Once the free cash flow is calculated, it can be discounted back to the present at either the firm’s WACC or the appropriate hurdle rate. The payback method calculates how long it will take to recoup an investment. One drawback of this method is that it fails to account for the time value of money. For this reason, payback periods calculated for longer-term investments have a greater potential for inaccuracy. The full calculation of the present value is equal to the present value of all 60 future cash flows, minus the $1 million investment. The calculation could be more complicated if the equipment was expected to have any value left at the end of its life, but in this example, it is assumed to be worthless.
As you can see in the screenshot below, the assumption is that an investment will return $10,000 per year over a period of 10 years, and the discount rate required is 10%. In addition to factoring all revenues and costs, it also takes into account the timing of each cash flow that can result in a large impact on the present value of an investment. For example, it’s better to see cash inflows sooner and cash outflows later, compared to the opposite. Net present value is used to determine whether or not an investment, project, or business will be profitable down the line. The NPV of an investment is the sum of all future cash flows over the investment’s lifetime, discounted to the present value. In the context of evaluating corporate securities, the net present value calculation is often called discounted cash flow (DCF) analysis.
Advantages of NPV
At face value, Project B looks better because it has a higher NPV, meaning it’s more profitable. For example, is the net present value of Project B high enough to warrant a bigger initial investment? Financial professionals also consider intangible benefits, such as strategic positioning and brand equity, to determine which project is a better investment. To calculate NPV, you have to start with a discounted cash flow (DCF) valuation because net present value is the end result of a DCF calculation. While you could calculate NPV by hand, you can use an NPV formula in Excel or use the NPV function to get a value more quickly. There’s also an XNPV function that’s more precise when you have various cash flows occurring at different times.
- Finally, a terminal value is used to value the company beyond the forecast period, and all cash flows are discounted back to the present at the firm’s weighted average cost of capital.
- NPV is the result of calculations that find the current value of a future stream of payments using the proper discount rate.

- To illustrate the concept, the first five payments are displayed in the table below.
- An investor can perform this calculation easily with a spreadsheet or calculator.
A project or investment with a positive NPV is implied to create positive economic value, whereas one with a negative NPV is anticipated to destroy value. The Net Present Value (NPV) is the difference between the present value (PV) of a future stream of cash inflows and outflows. Also, for financial modeling and audit purposes, it’s harder with Method Two than with Method One to determine the calculations, figures used, what’s hardcoded, and what’s input by users. The present value method is preferred by many for financial modeling because its calculation and figures are transparent and easy to audit.

NPV plays an important role in a company’s budgeting process and investment decision-making. It requires the discount rate (again, represented by WACC), and the series of cash flows from year 1 to the last year. Be sure that you don’t include the Year zero cash flow (the initial outlay) in the formula. Assume the monthly cash flows are earned at the end of the month, with the first payment arriving exactly one month after the equipment has been purchased.
The WACC is used by the company as the discount rate when budgeting for a new project. When multi-year ventures need to be assessed, NPV can assist the financial decision-making, provided the investments, estimates, and projections are accurate. It is a comprehensive way to calculate whether a proposed project will be financially viable or not. If, on the other hand, an investor could earn 8% with no risk over the next year, then the offer of $105 in a year would not suffice.
From the second year (year one) onwards, the project starts generating inflows of $100,000. They increase by $50,000 each year till year five when the project is completed.

The number of periods equals how many months or years the project or investment will last. Sometimes, the number of periods will default to 10, or 10 years, since that’s the average lifespan of a business. However, different projects, companies, and investments may have more specific timeframes. Cash flows are any money spent or earned for the sake of the investment, including things like capital expenditures, interest, and loan payments.
NPV for a Series of Cash Flows
As NPV considers the time value of money, it provides a deeper insight into the viability of your investment options. Of course, there’s no reason to calculate NPV by yourself, especially since there are so many NPV calculators available to use instead. Investopedia provides a simple NPV calculator that you can use to determine the difference between the value of your cash inflows and cash outflows.
How about if Option A requires an initial investment of $1 million, while Option B will only cost $10? The NPV formula doesn’t evaluate a project’s return on investment (ROI), a key consideration for anyone with finite capital. Though the NPV formula estimates how much value a project will produce, it doesn’t show if it’s an efficient use of your investment dollars. A notable limitation of NPV analysis is that it makes assumptions about future events that may not prove correct.
NPV vs. Payback Period
You can use the basic formula, calculate the present value of each component for each year individually, and then sum all of them up. An NPV of greater than $0 indicates that a project has the potential to generate net profits. Usually, NPV is just one metric used along with others by a company to decide whether to invest.
On the downside, the initial cash outlay must be netted out manually, a need that can be overlooked by Excel users. Analysts, investors, and economists can use either of the methods, after assessing their pros and cons.

And the future cash flows of the project, together with the time value of money, are also captured. Therefore, even an NPV of $1 should theoretically qualify as “good,” indicating that the project is worthwhile. In practice, since estimates used in the calculation are subject to error, many planners will set a higher bar for NPV to give themselves an additional margin of safety. As long as interest rates are positive, a dollar today is worth more than a dollar tomorrow because a dollar today can earn an extra day’s worth of interest.
