Net Present Value Calculator
What is NPV?
Net present value (NPV) discounts every future cash flow to today and subtracts the initial investment. A positive NPV means the project earns more than the discount rate on a present-value basis. Pair this tool with the IRR calculator and the NPV vs IRR guide when ranking projects.
For uneven series without a separate outlay field, the cash flow calculator remains useful; for a single future amount, use the present value calculator.

Example
Outlay −$100,000; five end-of-year inflows $30k–$50k; r = 10%. If NPV is positive, the project clears a 10% hurdle rate in present-value terms.
