The Excel XNPV function calculates the Net Present Value for a schedule of cash flows that is not necessarily periodic.
The syntax of the function is:
Where the arguments are:
|rate||-||The discount rate to apply to the cash flows.|
|dates||-||An array of dates corresponding to the array of payments. This array must be the same length as the supplied values array.|
|1||5%||- Discount rate|
|2||Jan-01-2016||-$10,000||- Initial investment cost|
|3||Feb-01-2016||$2,000||- Return from year 1|
|4||May-01-2016||$2,400||- Return from year 2|
|5||Jul-01-2016||$2,900||- Return from year 3|
|6||Nov-01-2016||$3,500||- Return from year 4|
|7||Jan-01-2017||$4,100||- Return from year 5|
|9||Net Present Value:|
|10||=XNPV( B1, B2:B7, A2:A7 )|
In the above spreadsheet on the right the Xnpv function is used to calculate the net present value of a series of cashflows.
The discounted rate is shown in cell B1 of the spreadsheet, the dates of the returns are stored in cells A2-A7 and the values of the returns are stored in cells B2-B7.
The Xnpv function, as shown in cell C10, is:
which gives the result $4,447.94
