As explained in the first lesson, Net Present Value (NPV) is the cumulative present worth of positive and negative investment cash flow using a specified rate to handle the time value of money.
If the calculated NPV for a project is positive, then the project is satisfactory, and if NPV is negative then the project is not satisfactory.
The following video, NPV function in Excel , explains how NPV can be calculated using Microsoft Excel (8:04).
PRESENTER: In this video, I'm going to explain how to use NPV function in Excel to calculate the NPV of a cash flow. There are two main ways of calling NPV function in Excel. The first method is clicking in this little Fx here. When you click that, this window pops up, and then you can search the NPV function in this box.
You click Go. It finds the NPV function, or you can go to the Financial category here and you will find the NPV function. And then you click OK.
You can see three boxes here. The first one is asking you to enter the Rate. This rate is the interest rate that you're going to discount your cash flow when you calculate the NPV. You can write a number here, which is going to be 10%, or you can rate these from a cell, which I wrote 10% here. Then after, we can click this one or we can push Enter.
And then after, you can enter the cash flow. You can enter the cash flow one by one, in each of these values, or you can choose the cash flow as a series here. Then you click here. If you entered everything correctly, the NPV is going to be calculated and the function shows the NPV here. If something is wrong, you won't see a correct NPV here. Then I click OK. So as you can see, the NPV is calculated and shown.
The other way to call the NPV function is you just write equal sign, and then write NPV open parentheses, the first one, and then you can see did this thing pops up. In the first, you need to enter a rate. You can write a value here-- you can write 10%, or you can read it from this cell. And then you write a comma, and then you enter the values. You start from here, go all the way to the end of the cash flow. And you close the parentheses.
So one thing that you have to be very careful using the NPV function in Excel is NPV function in Excel always considers you are entering your cash flow from year 1. So if you have the cash flow that is happening at the present time, at time 0-- at year 0-- you have to enter that manually. NPV function in Excel does not consider any cash flow at time 0-- it doesn't understand a time 0. NPV assumes that you are entering everything from year 1.
So you can always double-check the result of this NPV function. If you calculate the present value of each of these payments, the summation of that discounted cash flow should be equal to this net present value. Let's quickly calculate that. Let's say we want to calculate the present value of these payments. The first one equals $50,000 divided by 1 plus interest rate. I put a dollar sign behind the column to fix this when I'm going to apply it to the other cells, and power, year.
So as you can see here, this is the present value of this $50,000 of investment. I apply that to the other cells. So the summation of this discounted cash flow, these present values, should be exactly the same as the NPV that we calculated using the NPV function in Excel, which you can see they are exactly the same.
So let's work on another example that has the cash flow at present time. So as you can see in this investment, we are going to have $60,000 of investment at present time, and also $50,000 of investment at year 1. This investment is going to yield the annual income of $24,000 a year, from year 2 to year 10. Let's see how we can calculate the NPV of this cash flow using the NPV function in Excel.
So as you can see here, because we are going to have a payment at present time, we need to enter that payment manually. So what we do is, we write the equal sign and then we add this payment, which is happening at the present time, or year 0. And then after, we use the NPV function for the rest of the cash flow. I write NPV-- I rate the interest rate from here. Then I select the cash flow, starting from the year 1 all the way to the year 10. I close the parentheses, and I press Enter. So this is the NPV, using the NPV function of this cash flow.
Let's double-check our result. Let's see if this is correct or not. So I'm going to calculate the present value of all these payments, and then the summation should be exactly same as this NPV-- using the NPV function. So present value equals this payment-- it is happening at the present time, so it doesn't need to be discounted. So it is equal same amount-- present value of this, $50,000, equals $50,000 divided by open parentheses 1 plus interest rate. I fix the column to make sure it doesn't change-- to make sure interest rates sale doesn't change when I'm going to apply to the other cells. I close the parentheses, and power, year. So this is the present value of this-- $50,000 happening at year 1.
So I apply this to the rest of cash flow, and the summation of this discounted cash flow should give me the exact same value as the NPV-- that I used the NPV function in Excel. As we can see, these are exactly the same.
So these are two ways of calculating NPV using Excel, and how we can double-check the other one.
In the video NPV and IRR in Excel 2010 (8:59) you can find another useful video for calculating NPV using Excel NPV function. In this video, cash flow is formatted in the vertical direction (there is absolutely no difference between vertical and horizontal formatting, using spreadsheet).
In the following video, IRR function in Excel , I'm explaining how to calculate the Rate of Return for a given cash flow using Microsoft Excel IRR function (4:19).
PRESENTER: In this video, I'm going to explain how to calculate rate of return for a given cash flow using IRR function in Excel. There are two ways that we can call IRR function. First, we can click on this fx icon. This window pops up, and we can write IRR in this box, which is a search box. Go, it finds it. Or, we can choose the financial from this list and find the IRR.
When we choose IRR, this window opens up. And it has two boxes. The first box needs you to enter the cash flow. There's a very important point in calling Excel IRR function. That requires you to enter the cash flow, and it assumes your cash flow starts from year zero. So you should be very careful using IRR function in Excel. It assumes your cash flow starts from year zero or present time.
So I select the cash flow starting from year zero. And I click here or press Enter. So here, it already calculated the IRR. But sometimes, the IRR function cannot find a rate of return. So you need to give it an initial guess. If you don't have any assumption in your mind, just give it 10%. If still it doesn't calculate it, give it 20%, and so on. And you press OK. So as you can see here, the rate of return for this cash flow, starting from year zero, is 14.06%.
The other way to call the IRR function in Excel is just writing the IRR function. You write the equals sign, and then you write IRR. You can see Excel shows this here, shows the function here. You open the parentheses. You select the cash flow from starting from year zero all the way to the year 10. A comma, and the initial guess, which is going to be 10%. And the result.
So we can always double-check this result that we calculated rate of return using Excel IRR function. As you know, rate of return is a rate that makes NPV equal zero. So if I calculate the NPV for this rate, it should be exactly zero, or very close to zero. So let's see. Let's calculate the NPV for this rate.
So because we are going to have a payment at present time, I have to enter that payment manually. And then I have to calculate the NPV of the rest of the cash flows that start from year one using the NPV function.
NPV, open parentheses. Rates. I choose the rate. Comma, and then I select the cash flow that starts from year one. And I close parentheses. And you can see the NPV equals zero. So it shows that the rate of return that I calculated for this cash flow is correct.
Please calculate the NPV for the following cash flow, considering minimum discount rate of 10% and 15%.
=60,000 | =50,000 | =24,000 | =24,000 | ... | =24,000 |
0 | 1 | 2 | 3 | ... | 10 |
C: Cost, I:Income
If using spreadsheet, following method can be more convenient:
Figure 3-5 illustrates the calculation of the NPV function in Microsoft Excel. Please note that in order to use the NPV function in Microsoft Excel, all costs have to be entered with negative signs.
Benefit Cost Ratio (B/C ratio) or Cost Benefit Ratio is another criteria for project investment and is defined as present value of net positive cash flow divided by net negative cash flow at i*.
For the project assessment:
Present Value Ratio (PVR) can also be used for economic assessment of project(s) and it can be determined as net present value divided by net negative cash flow at i*.
Calculate the B/C ratio and PVR for the cash flow in Example 3-6.
Figure 3-6 illustrates the calculation of the B/C function in Microsoft Excel. Please note that you need to use the absolute value in the denominator or multiply the answer by -1.
Figure 3-7 illustrates the calculation of the PVR function in Microsoft Excel. Please note that you need to use the absolute value in the denominator or multiply the answer by -1.

Evaluate the return and payback on a company's capital investment
Most companies make long-term investments that require a large amount of capital invested in the initial years, mostly in fixed assets such as property, machinery, or equipment . Due to the significant amount of cash outflows required, companies perform a capital investment analysis to evaluate the profitability of an investment and determine whether it is worthy. This is especially important when a business is presented with multiple potential opportunities and needs to make an investment decision based on the long-run returns they can get.
To assess the profitability of a capital investment, companies can build a capital investment model in Excel to calculate key valuation metrics including the cash flows , net present value (NPV) , internal rate of return (IRR) , and payback period .
In this guide, we will outline the major line items that should be included in a capital investment model and how to use the calculated metrics to evaluate the investment.
The first step to building a capital investment model is to determine the cash flows for the investment period. In this simplified model, we are presenting the income statement using the minimal number of line items – revenue, expenses, and profit. By subtracting the expenses from the annual revenue we can determine the profit for each year within the investment period, which will be used as cash inflows for the capital investment.
Next, we need to determine the amount of capital invested in the project, which equals the cash outflows during the investment period. With that information, we can then calculate the annual cash flows using the following formula:
Cash Flow (Annual) = Profit – Capital Investment
The cash flow line will be the major input in the calculations of net present value (NPV) and internal rate of return (IRR) for this capital investment.
We also need to determine the cumulative cash flow, which is essentially the sum of all cash flows expected from the investment. The cumulative cash flow figures will be used to compute the payback period of the investment.
The net present value (NPV) is the value of all future cash flows over the entire life of the capital investment discounted to the present. In this example, we will determine the NPV using three different discount rates – 10%, 15%, and 20%. This rate is often a company’s weighted average cost of capital (WACC) , or the required rate of return investors expect to earn relative to the risk of the investment.
In Excel, you can use the NPV function to find the present value of a series of future cash flows with equal time periods. The formula for the NPV function is = NPV(rate, cash flows).
In this example, the NPV of this capital investment would be $120,021 when the discount rate is 10%, $77,715 when the discount rate is 15%, and $48,354 when the discount rate is 20%. It tells us that when there is a higher risk associated with a capital investment, investors expect to pay less today and a higher return in the future.
The internal rate of return (IRR) is the expected compound annual rate of return earned on a capital investment. IRR is usually compared to a company’s WACC to determine whether an investment is worthy or not. If the IRR is greater than or equal to the WACC, then the company would accept the project as a good investment. Vice versa, the company would reject the investment if the IRR is less than the WACC.
You can use the IRR function in Excel to compute the rate of return based on a series of future cash flows. The formula for the IRR function is =IRR(rate, cash flows).
The last metric to calculate for a capital investment is the payback period , which is the total time it takes for a business to recoup its investment. The payback period is similar to a breakeven analysis but instead of the number of units to cover fixed costs, it looks at the amount of time required to return the investment.
A simple way to calculate the payback period is to count the number of periods until the company earns a positive cumulative cash flow on the investment. In the example provided, the company starts to have positive cumulative cash flow in year 5 and, thus, the payback period for this investment is 5 years.
Besides calculating the payback period, a cash flow chart is also a good way to visualize the cash flow trend over the investment period and the time when the investment breaks even. In the example above, the column chart in blue represents the annual cash flow of the investment, while the line chart in orange shows the cumulative cash flow over the period.
The point where the orange line intersects with the horizontal axis is the breakeven point, where the company earns zero cumulative cash flow and begins to recognize positive cash flow after paying back all of the initial investment.

A cash flow or profit forecast answers, “What do I expect to happen?” You then use ratios and other metrics to answer, “Is that good enough to proceed?”
In this article, I’ll walk through three common metrics used to assess the return on investments:
Internal rate of return (irr), time to break even.
I’m not going to give you the formulas for most of these metrics, but I will show you how to derive them in Excel. For you math fans, you can click on these links to dig into the formulas: IRR and NPV .
Net Present Value answers the question, “Is the current value of cash flows enough to justify this investment?”
The net present value of a series of cash flows is their value today. You can’t just add up the cash flows to get this number because one dollar today is worth more than getting one dollar in the future. This is called the time value of money.
The economic theory behind this is that if you give me one dollar today I can invest it to get more than one dollar in a year. For example, I can put in a savings account and get one dollar and three cents in a year. That assumes I’m perfectly rational and self-controlled. Economists’ assumptions aren’t based on normal people that have a knack for losing money from bad decisions, lack of control, or bad luck.
The huge assumption with NPV, aside from the cash flows, is the discount rate. What rate should you use? A good starting point is your weighted average cost of capital. In other words, what’s the weighted average cost of the funds you will use? Let’s say the company owners expect a 10% return on their cash and can borrow money at 6%. If the location is financed by cash, you would use 10%. If you were funding half of it with cash and half with debt, then you may use 8%. You should then adjust that for the riskiness of the project.
Excel has two NPV formulas:
Here is a table of sample cash flows discounted by an assumed 10% discount rate.
The formula in cell C3 for NPV is: =NPV(C2,B6:B10). I also showed at the bottom of the image how each year’s discounted cash flow sums up to the total NPV of the project. The NPV function assumes that cash flows occur at the end of each period, which means the cash flow for year one occurs one year in the future.
What do you do if your cash flows occur at the beginning of the year? This is common since the initial investment often occurs on day one, while the cash flows of the investment occur over multiple years. In that case, you would discount the cash flows at the end of periods 1-4. Then add the initial investment as an undiscounted cash flow. The timing of the payments to be discounted is still a bit imprecise, which can be fixed with XIRR, which I’ll discuss later.
What you are hoping for is at least a positive number. Your discount rate should be the risk-adjusted minimum rate of return you would want from the project. When comparing projects, you would lean toward picking the projects with the highest NPV.
In this example, the NPV is negative, which means we may not want to open the new location. It may still make sense to open the new location if there are qualitative factors that offset the negative NPV.
NPV can change based on how many years you project. I only projected five years in this analysis. If I projected two more years of $155,000 of cash flow, the NPV jumps to $44,553. The longer into the future that you project, the less certain of the cash flows you become. This is why you may be OK with only projecting five to ten years in the future. If you are buying or constructing the location, make sure to put the sale value of the building at the end of the cash flows.
I mentioned earlier that Excel’s IRR function assumes payments occur at the end of each period. It also assumes that all periods are the same length. What if you want more precise dates for cash flows or if they occur at differing lengths of time? That’s when you use Excel’s XNPV function.
The formula for XNPV is =XNPV(Discount Rate, Series of Values, Dates for Values).
The formula for XNPV in cell D3 is: =XNPV(D2,C6:C11,A6:A11).
I set up this to match the NPV example, so the dates occur at the end of each year. The eagle-eyed auditor types out there may notice that the sum of the annual discounted cash flows doesn’t equal the XNPV formula. What’s going on?
Cash flows dated the last day of each year don’t all have the same length of time between cash flows. The discount rate I used on each yearly row assumes they do like the NPV formula does.
Leap years have 366 days; all other years have 365 days. 2024 is a leap year.
In this example, I adjusted the dates for 2024 and 2025, so now each year is 365 days long. Now XNPV matches the yearly totals.
This shows how XNPV can show different (and more accurate) results for cash flows that are just one day different. More importantly, your projection is likely a series of months (rather than years) whose dates range from 28-31 days. XNPV is more accurate in this situation.
The accuracy of XPNV increases compared to NPV as the difference in the number of days in each period increases. You will want to use XNPV if your cash flows have highly irregular timing.
The questions you may answer with IRR are:
The internal rate of return, or IRR, is the discount rate for the cash flows on an investment to equal the initial investment. You could think of it as the yield or return on your investment. The question you want to ask is whether the IRR is higher than the yields on other investment options you have.
The Excel formula for IRR is fairly simple: =IRR(series of values)
The formula for IRR in cell C2 is: =IRR(B6:B10). Like NPV, Excel assumes cash flows occur at the end of each period.
This table shows the year of the cash flows and their discounted values at the IRR. Notice that the sum of the discounted cash flows equals zero when you use the IRR as the discount rate.
Like NPV, IRR can change based on how many years you project. I only projected five years in this analysis. If I projected two more years of $155,000 of cash flow, the IRR would jump to 19%.
Using Excel’s XIRR Function
XIRR returns the internal rate of return for a series of cash flows where you provide both the timing of the cash flows and their amounts. This will provide a more accurate result, especially if your cash flows rise and fall at different times. You likely are projecting both the dates (e.g., months) and the cash flow amounts, so this is the better formula if you have that data for the formula.
The formula for XIRR is =XIRR(Series of Values, Dates for Values). The formula for XIRR in cell D2 is: =XIRR(C7:C11,A7:A11).
I set up this to match the IRR example, so the dates occur at the end of each year. Once again, this creates a small difference between the annual discounted cash flows (using the equal length of time assumption) and XIRR.
I adjusted the dates as I did for XNPV to show that XIRR will match the sum of the yearly cash flows when every time period is the same length.
Like XNPV, XIRR the accuracy of XIRR increases compared to IRR as the difference in the number of days in each period increases. You will want to use XIRR if your cash flows have highly irregular timing. Using XIRR instead of IRR is very easy if you already have dates in your projection.
Time to Break Even answers:
A shorter time to break even may also indicate less risk. Your ability to accurately predict cash flows diminishes as the projection horizon increases.
The time to break even is the number of months or years until the cumulative cash flows from the new location rise above zero. It’s when your initial investment is finally paid back.
The benefit of this is that it’s much easier to understand than NPV or IRR. On the other hand, it’s harder to judge the return of the location and compare its profitability to other projects.
Here’s an example of the time to break even. The breakeven occurs sometime in year 5.
You can perform this on cash flows or profit amounts.
Which metric is best? There is rarely one number that tells you everything to make a decision. Each of these metrics helps you analyze an investment from a different perspective. Your company and industry metrics add further perspectives and points of comparison.
Metrics do help condense all the assumptions and projections into yes/no questions.
Your analysis will be challenged by people who don’t like the answers to these questions. If they can’t discredit the assumptions and analysis, they’ll point to qualitative factors that “you can’t measure” or “you aren’t considering.”
I created a loan pricing system for a bank. Loans had to meet a hurdle rate of return. If they didn’t, the joke was that the loan officer would say, “But this customer is a great referral source.”
It’s true that not everything can be measured. If the decision is financial, those qualitative factors eventually need to produce cash flows. You will need to arrive at some estimate or range of estimates for the future cash flows of the qualitative factors so they can be added to the analysis.
The qualitative factors may fulfill some other non-financial purpose of the company. For example, the location may benefit an underserved population that the owners want to serve. In that case, you’ll need to weigh the financial results of the analysis with the non-financial benefits.

Determining npv, determining irr, what is the formula for npv, what does a negative npv indicate, which is better: npv or irr, the bottom line.
Net present value (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time. By contrast, the internal rate of return (IRR) is a calculation used to estimate the profitability of potential investments.
Both of these measurements are primarily used in capital budgeting , the process by which companies determine whether a new investment or expansion opportunity is worthwhile. Given an investment opportunity, a firm needs to decide whether undertaking the investment will generate net economic profits or losses for the company.
To do this, the firm estimates the future cash flows of the project and discounts them into present value amounts using a discount rate that represents the project's cost of capital and its risk. Next, all of the investment's future positive cash flows are reduced into one present value number. Subtracting this number from the initial cash outlay required for the investment provides the net present value of the investment.
Let's illustrate with an example: suppose JKL Media Company wants to buy a small publishing company. JKL determines that the future cash flows generated by the publisher, when discounted at a 12% annual rate, yields a present value of $23.5 million. If the publishing company's owner is willing to sell for $20 million, then the NPV of the project would be $3.5 million ($23.5 - $20 = $3.5). The NPV of $3.5 million represents the intrinsic value that will be added to JKL Media if it undertakes this acquisition .
So, JKL Media's project has a positive NPV, but from a business perspective, the firm should also know what rate of return will be generated by this investment. To do this, the firm would simply recalculate the NPV equation, this time setting the NPV factor to zero, and solve for the now unknown discount rate . The rate that is produced by the solution is the project's internal rate of return (IRR).
For this example, the project's IRR could—depending on the timing and proportions of cash flow distributions—be equal to 17.15%. Thus, JKL Media, given its projected cash flows, has a project with a 17.15% return. If there were a project that JKL could undertake with a higher IRR, it would probably pursue the higher-yielding project instead.
Thus, you can see that the usefulness of the IRR measurement lies in its ability to represent any investment opportunity's possible return and compare it with other alternative investments.
Let's imagine a new project that has the following annual cash flows:
A single IRR can't be used in this case. Recall that IRR is the discount rate or the interest needed for the project to break even given the initial investment. If market conditions change over the years, this project can have multiple IRRs. In other words, long projects with fluctuating cash flows and additional investments of capital may have multiple distinct IRR values.
Another situation that causes problems for people who prefer the IRR method is when the discount rate of a project is not known. In order for the IRR to be considered a valid way to evaluate a project, it must be compared to a discount rate. If the IRR is above the discount rate, the project is feasible. If it is below, the project is considered not doable. If a discount rate is not known, or cannot be applied to a specific project for whatever reason, the IRR is of limited value. In cases like this, the NPV method is superior. If a project's NPV is above zero, then it's considered to be financially worthwhile.
The formula for NPV is:
Investopedia
If the net present value of a project or investment is negative, then it is not worth undertaking, as it will be worth less in the future than it is today.
It depends. IRR is usually more useful when you are comparing across multiple projects or investments, or in situations where it is difficult to determine the appropriate discount rate. NPV tends to be better for when cash flows may flip from positive to negative (or back again) over time, or when there are multiple discount rates.
Both IRR and NPV can be used to determine how desirable a project will be and whether it will add value to the company. While one uses a percentage, the other is expressed as a dollar figure. While some prefer using IRR as a measure of capital budgeting, it does come with problems because it doesn't take into account changing factors such as different discount rates. In these cases, using the net present value would be more beneficial.
CBInsights. " What is the NPV Formula in Excel? "
When you prepare a project in line with PMI or other established project management methodologies , you will have to create a project business case. This business case is usually a study on the expected qualitative and financial benefits of a single project or different project options. An essential part of this process is the cost-benefit analysis (sometimes also called benefit-cost analysis).
What is a cost-benefit analysis used for, net present value (npv), benefit-cost ratio (bcr), payback period (pbp / pbp), return on investment (roi), internal rate of return (irr), comparison of approaches – differences between npv vs bcr vs pbp vs roi vs irr, step 1) define the scope and purpose of a cost-benefit analysis, step 2) define the fundamental assumptions, step 3) determine the qualitative advantages and disadvantages of a project or investment option, step 4) develop a forecast of investments, costs and benefits, step 5) choose the methods to assess a project option (e.g. npv, bcr, irr), step 6) calculate the value of the success measures, step 7) consolidate, compare and interpret the results, forecast of cash flows, determination of the discount rate, comparison of npv, bcr, pbp, roi and irr results.
Before a project is initiated, the potential benefits need to be analyzed in a project business case. This document is also the basis for stakeholder decisions and the selection of project options.
The Project Management Institute (PMBOK®, 6 th ed., part 1, p. 30) defines the business case as a ‘documented economic feasibility study’ that outlines the business needs, the current situation, an economic analysis and recommendations. In practice, the structure of business case documents is typically tailored to the requirements and expectations of the stakeholders and the organization. In order to evaluate the economic effects of a project and make different project options comparable, project managers leverage the tools and techniques of the cost-benefit analysis (see next section).
A business case is often accompanied by a benefits management plan (which is also suggested by the PMBOK). This document sets out how the project is going to ensure that the expected benefits will eventually materialize in reality. Both the business case and the benefits management plan are the foundation and input documents of the project charter which is the formal documented authorization and mandate for the initiation of a project.
A cost-benefit analysis is an economic evaluation of investment alternatives and project options with respect to their profitability and liquidity effects. It can also consider non-financial and qualitative aspects which however may or may not be reflected in the forecast of cost and benefits.
Besides forecasting investments, cost and benefits over an individually defined time horizon, a cost-benefit analysis usually involves a number of indicators. These measures aggregate forecasts and assumptions into catchy numbers that can be used for comparison and communication purposes.
Discounting cash flows, determining the amortization time, and calculating return rates are the most common approaches for calculating key performance indicators of a forecast in a cost-benefit analysis. We will cover these approaches in detail in the next section.
There are several reasons for using a cost-benefit analysis. The most obvious one is to determine the expected financial returns and profitability of an investment or a project. Subsequently, different options can be compared with each other based on cost-benefit analyses. This can be the basis for decision-making and the selection of the alternative or option to go for (source). This is a typical step before project initiation and often part of a project business case.
The initial cost-benefit analysis results also serve as a baseline for the measurement of success in an ongoing project. Thus, they help project managers, sponsors and other stakeholders to measure, monitor and manage the value a project is creating against the original expectation.
Although the cost-benefit analysis is not an original risk management technique, its results can be used to assess and consider certain risks of a project. An example is a benefit-cost ratio greater than 1: the closer it gets to 1, the higher the risk that even small deviations from the forecasted benefits lead to a loss-producing project.
On the other side, discounted cash flow-based approaches can be calculated using a risk-adjusted discount rate. This allows taking inherent risk into account when net present values or benefit-cost ratios are calculated.
An inevitable part of a project business case and a cost-benefit analysis are certain success measures. While the set of indicators needs to be in line with the organization’s requirements, there are in fact a number of very common indicators that are introduced below. Although the following list is not exhaustive, it covers the generic types of the most common success measures, namely:
These success measures allow project managers to conduct a balanced cost-benefit analysis that covers different aspects such as profitability, liquidity and riskiness of project options. At the same time, these indicators are comparatively simple to calculate and easy to understand in the course of stakeholder communication .
The NPV represents the present value of a series of cash flows. The calculation involves the discounting of net cash flows with a discount rate. This rate is part of the set of assumptions required for applying the net present value method.
The underlying series of cash flows begins with the initial investment as an outflow, followed by net cash flows for each period of the time horizon of the forecast. Future cash flows and a remaining value (or salvage value), as well as disposal costs or further returns expected in subsequent periods, are reflected in a residual value.

The benefit-cost ratio compares the present values of all benefits with the present value of all costs expected in a project or investment. A value greater than 1 indicates a profitable project with a total return exceeding the discount rate. A value of less than 1 suggests that the forecasted series of cash flows is not a profitable option.

The payback period determines the period in which the cumulative cash flows of a project turn positive for the first time. At that point, the initial investment has been ‘paid back’.
The series of cash flows usually starts with an investment (an outflow, hence a negative number), followed by positive and/or negative net cash flows. These can be even, i.e. the net cash flow remains constant for the entire forecast horizon, or uneven with different values among the periods of a forecast.
When determining the payback period, the generic approach does not use any discount rates or other adjustments which may be inaccurate for long-term forecasts. However, there are a number of modified PbP approaches that can be used to resolve this disadvantage.

The basic formula of the ROI is a division of expected constant returns by the investment amount. It is usually calculated for only one period. However, there are several variants of the return on investment method, including a cumulative and annualized ROI (for multiple periods).

The internal rate of return is determined by using a net present value calculation. The IRR is the discount rate that would lead to an NPV of 0 if applied to the individual forecast. The resulting rate is the fictive interest or return rate of an investment.

Follow these 7 steps to prepare a cost-benefit analysis. You will need some input data, as set out in the individual steps, a calculator and a fundamental understanding of the aforementioned indicators. You can download this checklist which will help you gather the required information and data.
The following steps refer to both the qualitative and the financial aspects of a cost-benefit analysis.
First things first: before you start assessing different project options or investment alternatives, make sure that you develop and agree on a clear definition of the scope and purpose of the analysis.
The scope describes what exactly you are going to evaluate. This may refer to high-level project options, single investments or other types of endeavors that are selected for the analysis. For a proper cost-benefit analysis, it should be clear which components are expected to be included (e.g. indirect / internal costs and benefits) and which are not (e.g. direct or indirect taxes).
Determining the purpose of the analysis relates to the expected result type. It clarifies whether solely economic aspects are to be considered, or whether qualitative criteria are also relevant and part of this analysis. A project manager should also be aware of whether profitability, liquidity or risk is the organization’s most relevant consideration.
Examples of cost-benefit analyses that may not solely focus on economic criteria are non-profit projects or social projects run by governments or NGOs.
Before you start, make sure that the basic assumptions of the analysis are known and will be considered in subsequent steps. Assumptions may range from implementation scenarios, headcount, resource needs, etc. to agreed expectations regarding the discount rate and the organization’s target profitability.
Make sure that you are incorporating and addressing all the criteria deemed important by the organization. If you compare different project options, it is crucial that the assumptions are used consistently among all the alternatives you are comparing.
If different or even contradicting types of assumptions are requested, you should consider assessing them separately and in different scenarios.
Gather and document the pros and cons of each and every option you are assessing. Group them into categories and compare them among each other, e.g. in a structure similar to our table in the previous section.
Depending on the type of project, you may wish to consider converting qualitative aspects into financial benefits or cash flow equivalents. This could be done for qualitative advantages that are indirectly affecting financial cash flows. Examples are increasing process efficiency, customer satisfaction and engagement as well as improved quality of products and services.
This may however not be working for other types of advantages and disadvantages. For instance, social and ecological considerations ( source ) as well as long-time effects such as brand image may not be convertible into cash flows of a mid-term forecast.
Come up with a forecast of future benefits and costs (or cash inflows and outflows), investment amounts and other financial considerations.
Depending on the complexity of the options that you are analyzing, you may want to involve subject matter experts to create or validate estimates.
This step usually requires a number of assumptions on a granular level. You should therefore develop an understanding of the uncertainty inherent in this forecast. If you are in doubt, you better create different scenarios (e.g. a base and a worst case) to reflect situations where things turn out differently than expected.
A cost benefit analysis can be performed with different tools and techniques. Net present value, benefit-cost ratio , payback period, return on investment and internal rate of return are the most common methods to assess economic effects from projects, investments and initiatives. Refer to the above-mentioned introduction and read the detailed articles on these measures. Eventually, you will come up with a set of indicators that is suitable for the individual situation.
If you have selected the indicators, you need to apply them to the forecasts that you have developed in a previous step. You will find the formulas in the detailed articles on those methods . When calculating the success measures, apply every method in a consistent manner to all options. This will ensure the comparability and thus the integrity of the results.
As a last step, consolidate all the aspects and results that you have produced in the course of the analysis. You can do this by creating a table that contains the calculated values, the qualitative pros and cons and a ranking of each of the options.
If you are working in scenarios, you will probably want to breakdown each option into the different scenarios (e.g. best, middle, worst case) that you have used previously.
At the completion of the cost-benefit analysis, you should have a clear view on the economic and qualitative aspects of the alternatives you are comparing. Ideally, you are able to recommend a certain option or discard others at this point.
In this illustrative example, we will compare 3 different project options for the implementation of a new IT system with each other. For illustrative purposes, the analysis focuses on the economic aspects only, not taking qualitative and strategic considerations into account.
In order to perform the cost-benefit analysis with all three options, the project manager has obtained estimates of the investments , running and maintenance costs and expected benefits. The benefits consist of both savings from more efficient processes and increased revenue given that the new software improves the way customers are served. The following table shows the consolidated forecast of the three alternatives.
Now | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Year 6 | |
Investment & Costs | -5,000 | -5,000 | -1,000 | -500 | -500 | -1,000 | -1,000 |
Benefits | – | – | 3,000 | 5,000 | 5,000 | 4,000 | 4,000 |
Net Cash Flow | -5,000 | -5,000 | 2,000 | 4,500 | 4,500 | 3,000 | 3,000 |
Now | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Year 6 | |
Investment & Costs | -15,000 | -1,000 | -1,000 | -1,000 | -500 | -500 | -1,000 |
Benefits | – | 2,500 | 5,000 | 5,000 | 5,000 | 5,000 | 5,000 |
Net Cash Flow | -15,000 | 1,500 | 4,000 | 4,000 | 4,500 | 4,500 | 4,000 |
Now | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Year 6 | |
Investment & Costs | -3,000 | -3,000 | -2,500 | -1,000 | -500 | -500 | -500 |
Benefits | – | – | 3,000 | 4,000 | 4,000 | 3,000 | 3,000 |
Net Cash Flow | -3,000 | -3,000 | 500 | 3,000 | 3,500 | 2,500 | 2,500 |
One could be tempted to simply calculate the sum of the cash flows. However, this is not an accurate approach to deal with cash flows occurring at different points in time. We will nevertheless use the simple sum in the result table for comparison purposes.
If one of the more accurate approaches such as NPV and BCR are used, a discount rate is necessary to perform the calculation. This discount rate can be a market interest rate which may be risk- or time-adjusted. In organizations and projects, more common alternatives are either the company’s target return rate or the cost of capital. In this example, the organization expects a return of 12% on all investments which will be used as a discount rate accordingly.
The following table compares the results of the different methods applied to this example. Refer to the dedicated articles on each of these indicators for the respective illustrated step-by-step calculation.
Rank | Project Option | Benefit Cost Ratio (BCR) | Net Present Value (NPV) | Payback Period (PbP) | Return on Investment (ROI) | Internal Rate of Return (IRR) | |
1 | Option 3 | 1.19 | 1,764.82 | 4.71 | 75.00% (annualized: 9.78%) | 20.68% | |
2 | Option 1 | 1.12 | 1,415.12 | 4.77 | 77.78% (annualized: 10.06%) | 16.76% | |
3 | Option 2 | 0.99 | -185.04 | 5.22 | 50.00% (annualized: 6.99%) | 11.61% |
Based on the economic cost-benefit analysis, Option 3 seems to be the most promising one in all measures except ROI. Although the simple sum of its net cash flows is the lowest in this comparison, it creates the highest net present value and the highest internal rate of return. This is because the period when expenses and benefits occur is considered in the NPV. It also comes with the highest benefit-cost ratio. Thus, there is a certain buffer if the benefits do not materialize in the way it was initially expected. With a payback period of 4.71, this option achieves a full amortization in less than 5 years which can be a reasonable time horizon for many organizations.
Option 2 which has the highest sum of non-discounted cash flows does in fact not even yield the required return rate of 12%. As this rate has been used as a discount rate, both the BCR and the NPV indicate a non-profitable investment.
Note that the ROI, as well as the annualized ROI, are not accurate for these examples. Refer to the detailed ROI calculation for further explanations. We have not included the Disconted Payback Period (DPP) as it is not mentioned in the PMBOK. You can find the DPP for the above case study in this article though.
This example refers to the economic aspects of a cost-benefit analysis. In practice, you would want to consider and analyze the qualitative pros and cons as well.
A proper project business case usually requires a financial cost-benefit analysis. While there are a number of calculation methods that help compare and evaluate different project options, you should be aware of the risks and weaknesses ( source ).
Financial models and indicators are always an abstraction of the reality and forecasts may or may not be met in reality. Therefore, all the methods introduced above rely on assumptions. In some cases, it may even be only one single figure turning it into a loss-producing or profitable option (e.g. a perpetuity in the NPV).
So, make sure you understand these dependencies, work with different scenarios if sensible and maintain a comprehensive and honest communication with the stakeholders. Read our detailed articles on cost-benefit analysis methods to learn more about these methods and use this checklist when doing a cost-benefit analysis.

The IRR or internal rate of return is a means of evaluating a project by finding the discount rate at which the net present value of the cash flows is equal to zero. At the IRR, the cash flow returned by the project is equal to the cash flow invested in the project. This free IRR calculator allows for up to five projects and ten years of future cash flows following the initial investment amount.
For example, if a project has an investment in year 0 of 20,000 and a cash inflow in year 1 of 21,000, then the IRR calculator shows the IRR is 5%, and the net present value of the cash flows at 5% would be zero.
If however, the business has a cost of borrowing or a required return higher than the IRR of say 8%, then the net present value of the cash flows would be negative (-556) and the project is probably not worthwhile.
Likewise, if the business has a cost of borrowing or required rate of return lower than the IRR say 2%, then the net present value of the cash flows would be positive (588) and the project probably is worthwhile.

Uncover the intricacies of Internal Rate of Return (IRR) with our in-depth guide. ... Cash Flow Considerations. Primarily, you'd want to have a look at the cash flows that occur at the beginning and end of each investment or project. In order to accurately estimate the IRR, you would need to consider both inflow and outflow of cash, typically ...
And then after, we use the NPV function for the rest of the cash flow. I write NPV-- I rate the interest rate from here. Then I select the cash flow, starting from the year 1 all the way to the year 10. I close the parentheses, and I press Enter. So this is the NPV, using the NPV function of this cash flow. Let's double-check our result.
The company must calculate the IRR for each project. This involves an iterative process. The IRR for Project A is approximately 16.61%, while the IRR for Project B is around 5.23%. Given that the company's cost of capital is 10%, management should proceed with Project A and reject Project B based on the IRR rule.
Internal Rate of Return Definition. Another common investment assessment approach is to calculate the Internal Rate of Return (IRR), which is also called the Discounted Cash Flow method. Essentially, the IRR is the rate at which the NPV of an investment equals zero. When you calculate IRR, you treat it as a cut-off point for investment decisions.
With that information, we can then calculate the annual cash flows using the following formula: Cash Flow (Annual) = Profit - Capital Investment. The cash flow line will be the major input in the calculations of net present value (NPV) and internal rate of return (IRR) for this capital investment.
The Excel formula for IRR is fairly simple: =IRR (series of values) The formula for IRR in cell C2 is: =IRR (B6:B10). Like NPV, Excel assumes cash flows occur at the end of each period. This table shows the year of the cash flows and their discounted values at the IRR. Notice that the sum of the discounted cash flows equals zero when you use ...
