NPV Calculator

Net present value prices a stream of cash flows in today's money by dividing each one by (1 + r) raised to its period number and adding the results. Enter the series starting at period 0 with outlays negative, or use the level-income mode for one outlay followed by equal receipts, and set the discount rate; back come the NPV, the present value of each period, the profitability index, discounted payback and the same series priced two points either side of your rate. The discount rate is an input, so it decides the answer: it is the return the money would otherwise earn, not something the tool can work out for you. Periods can be years, quarters or months as long as the rate matches them. If you want the rate that drives the NPV to zero instead, that is the internal rate of return and it has its own page.

Calculator Type

Type the whole series, starting with period 0. Money out is negative, money in is positive.

Separate with commas or spaces. An outlay today is the first figure and is usually negative.
The return the money could earn elsewhere, per period, not per year unless the periods are years.
