Net Present Value Calculator

Discount cash flows, compare IRR and payback, run sensitivity analysis, and model growing annuities — all in one NPV toolkit.

How It Works

  1. Enter discount rate and cash flows. Use comma-separated values — the first is usually the initial investment (negative).
  2. Read NPV. Positive NPV means the project adds value at your discount rate; negative means it destroys value.
  3. Year-by-year table. See present value of each period with an editable year table and initial investment.
  4. IRR, PI & payback. Compare internal rate of return, profitability index, and simple payback period.
  5. Sensitivity & growth. Test ±2% rate changes or model constant/growing annual cash flows.
