Key Takeaways Net present value, or NPV, is used to calculate the current total value of a future stream of payments. If the NPV of a project or investment is positive, it means that the discounted present value of all future cash flows related to that project or investment will be positive, and therefore attractive. To calculate NPV, you need to estimate future cash flows for each period and determine the correct discount rate.
NPV can be calculated using tables, spreadsheets for example, Excel , or financial calculators. Article Sources. Investopedia requires writers to use primary sources to support their work.

The payback period refers to the amount of time it takes to recover the cost of an investment or how long it takes for an investor to hit breakeven. What Is a Hurdle Rate? A hurdle rate is the minimum rate of return on a project or investment required by a manager or investor.
What Is a Discount Rate? I can refer to the interest rate that the Federal Reserve charges banks for short-term loans, but it's also used in future cash flow analysis.
Partner Links. And while determining the future cash flows of a business is beyond the scope of this discussion, the key point is that a prospective investment could be a good deal, or a bad one, depending on the discount rate alone.
Example 1. Notably, the key determinant of the discount rate is not based on the investment itself, per se, but on the opportunity cost of using that money in lieu of some other alternative, instead. Click To Tweet. A pension is a guaranteed lifetime stream of cash flows, which inherently makes it difficult to evaluate relative to other more traditional investment alternatives.
Example 2. Another way of evaluating the decision of whether to take a pension lump sum or not is to calculate what discount rate is actually being used to provide the pension lump sum.
Example 2b. In this case, the IRR would be 5. To the extent that the lump sum investor could earn anything greater than 5. Of course, this is ultimately an unknown, particularly for an individual; while on average year-old males like Charlie may leave to age 87 which can be predicted fairly accurately thanks to the law of large numbers , Charlie himself might live much longer or shorter than this time period.
Which matters because having a longer time period, and receiving more pension payments, improves the internal rate of return of the pension compared to the lump sum, and makes the pension inherently more valuable.
Accordingly, the chart below shows the internal rate of return for Charlie, and how it changes as each additional pension payment is received from age 65 all the way to age In all cases, though, the fundamental point of the discount rate remains the same: it represents the opportunity cost of not taking the lump sum and investing it and spending from it , and should be compared to the available investment rate of return in the portfolio.
The higher the expected rate of return — the better the investment opportunities for the lump sum — the more discounted i. In this case, the challenge is that both alternatives — take lifetime payments early, or wait and take higher lifetime payments starting later — involve a series of lifetime payments over the span of years and decades, but with different starting points, which makes them difficult to compare.
As a result, one of the most common approaches to evaluating Social Security trade-offs is to calculate the discounted net present value NPV of each choice, and then see which one has the higher value.

Then add them together. That will be the present value of all your projected returns. You then subtract your initial investment from that number to get the NPV. If the NPV is negative, the project is not a good one. It will ultimately drain cash from the business. The larger the positive number, the greater the benefit to the company. Now, you might be wondering about the discount rate.
There are two things that managers need to be aware of when using NPV. The first is that it can be hard to explain to others.
