# NPV versus XNPV Excel Functions Tutorial

The NPV (Net Present Value) Function is used to calculate the net present value of an investment by evaluating a provided discount rate, a series of future payments (negative values) and income (positive values). The XNPV Function is used to return the net present value for a schedule of cash flows that are not periodic. The NPV is mostly utilized in capital budgeting in order to give an indication of the profitability of a projected investment. An investment calculation that yields a positive NPV, will more than likely be a profitable investment, whereas an investment calculation that results in a negative NPV will more than likely yield a loss. When one has calculated the NPV value for multiple investments and they all yield positive results, then it is advisable to invest in the project with the highest NPV value.

The syntax of the NPV function is:

The syntax of the XNPV function is:

So, let’s get started with a simple example to illustrate what NPV and XNPV are used for, and the main difference between them.

## Calculating NPV

The annual discount rate of an investment is 3%, the initial investment cost one year from today is $19,000. The return from year 1 is $5,000, year 2 is $5,500, year 3 is $5,700 and the return from year 4 is $6,200.

1) In order to calculate the NPV, in Cell C9 we input the following formula:

*=NPV (C3, C4, C5, C6, C7, C8)*

2) Upon pressing CTRL-ENTER, a positive value of $1 712.21 is returned which means that the investment would more than likely be profitable. An investor would thus be advised to consider this investment.

A point of value to note is that because the initial payment occurs at the end of the first period, this value is used as value1. If the payment was made at the beginning of the first period, it would not be included in the arguments input to the NPV function and instead added to the result afterward.

## Calculating XNPV

The discount rate of an investment is 3%, the initial investment cost made is $9,000. The return from 2 February 2017 is $2,000, the return from 7 March 2017 is $2,200, from 10 September 2017 is $2,800 and from 3 January 2018 is $2,900.

1) In order to calculate the XNPV, in Cell C9 we input the following formula:

*=XNPV (C3, C4: C8, A4: A8)*

2) Upon pressing CTRL-ENTER, a positive value of $741.79 is returned which means that the investment would more than likely be profitable. An investor would thus be advised to consider this investment.

## Conclusion

The main difference between the NPV and the XNPV functions are that the values input in the NPV function are equally spaced, whereas the values input in the XNPV function are not equally spaced and thus related to an exact date.
