Net Present Value Calculator
Calculate the NPV of a series of future annual cash flows discounted at a chosen rate, minus the initial investment. A positive NPV means the investment creates value.
Inputs explained
- Initial Investment — The upfront amount invested (entered as a positive number). Example: 10000.
- Discount Rate — The annual rate used to discount future cash flows, as a percentage. Example: 10.
- Annual Cash Flows — The cash received each year, comma-separated in order. Example: 3000, 4000, 5000, 4000.

Understanding the result
Example: Investing $10,000 with cash flows of $3,000, $4,000, $5,000, $4,000 at a 10% discount rate gives an NPV of about $2,521.69.
Frequently asked questions
What does it mean if the NPV comes out negative? A negative NPV means the discounted future cash flows are worth less than the initial investment, so the project would destroy value at the chosen discount rate rather than create it.
How sensitive is NPV to the discount rate you choose? Very sensitive — raising the discount rate reduces the present value of every future cash flow, so a project that looks profitable at 10% can show a negative NPV at 15%; the rate should reflect your actual cost of capital or required return.
