IRR & NPV Calculator
Calculate Internal Rate of Return and Net Present Value for a series of cash flows.
How IRR & NPV Work
NPV (Net Present Value) = Sum of all cash flows discounted back to present value minus the initial investment. If NPV > 0, the investment is profitable. IRR (Internal Rate of Return) is the discount rate that makes NPV = 0 — essentially the expected annual return. Payback Period shows how long it takes to recover the initial investment. Profitability Index = PV of future cash flows / Initial Investment; PI > 1 means the project creates value.
