Difference between NPV and XNPV

Difference between NPV and XNPV

The NPV (net present value) and XNPV (extended net present value) formulas are used to calculate the present and future cash flows of a project. The main difference between the two formulas is that the NPV formula uses the company’s required rate of return, while the XNPV formula uses a weighted average cost of capital. Both formulas are important in determining whether a project is worthwhile for a company.

What is NPV?

NPV is a financial metric that measures the difference between the present value of cash inflows and the present value of cash outflows. NPV can be used to assess the profitability of an investment or compare different investments. The NPV formula is as follows: NPV = C1/(1+r) + C2/(1+r)^2 + … + Ci/(1+r)^i – P0, where C1, C2, … ,Ci are the cash inflows, r is the discount rate, and P0 is the initial investment.

NPV is typically used with a discount rate that reflects the riskiness of the investment. For example, if an investment has a higher risk, a higher discount rate will be used. NPV can be a useful tool for making investment decisions. However, it is important to note that NPV is only one metric that should be considered when making investment decisions. Other factors such as risk and return should also be taken into account.

What is XNPV?

XNPV is the discounted value of cash flow based on a certain interest rate. XNPV formula is one of the most important methods used in finance to determine the present value of an investment. XNPV can be applied to any kind of investment, including stocks, bonds, real estate, and mortgages. The XNPV formula takes into account the time value of money, which states that money today is worth more than money in the future. This is because money today can be invested and earn interest, while money in the future cannot. The XNPV formula discounts cash flow at a given interest rate to find the present value of that cash flow.

The XNPV formula is: XNPV = ∑​t=1nCFt(1+r)t Where: XNPV = Net Present Value CFt = Cash Flow at period t r = Discount Rate n = Number of periods XNPV is a critical tool for investment analysis because it allows you to compare different investments on a level playing field. By discounting all future cash flows to the present, you can see whether one investment is better than another from a purely financial perspective. XNPV is also important for capital budgeting decisions.

Difference between NPV and XNPV

NPV and XNPV are two formulas used to derive the cash flow of a project. NPV stands for net present value and XNPV stands for extended net present value. NPV is the sum of all cash flows discounted at the project’s cost of capital, while XNPV is the sum of all cash flows discounted at a rate that reflects the project’s true cost of capital.

The main difference between NPV and XNPV is that NPV only accounts for the time value of money, while XNPV also accounts for the riskiness of the project. As a result, NPV will usually underestimate the true cost of a project, while XNPV will usually provide a more accurate estimate. This makes NPV more useful for evaluating projects with low risk, while XNPV is more useful for evaluating projects with high risk.


The NPV and XNPV formulas are two different methods of deriving a cash flow. Both have their own advantages and disadvantages, which we’ve outlined in this blog post. It’s important to understand the difference between the two so you can choose the right one for your needs.
