About the IRR Calculator
The internal rate of return (IRR) is the discount rate at which an investment breaks even (net present value = 0). Enter the initial investment, the annual cash flow, and the number of years and the calculator solves for the IRR. It's a core metric for comparing projects and investments on an equal footing.

Frequently asked questions
What is IRR?
The discount rate that makes an investment's net present value zero. A higher IRR means a more attractive investment, all else equal.
How is IRR different from ROI?
ROI is a simple total return; IRR accounts for the timing of cash flows and the time value of money, so it's more rigorous.
