About this IRR calculator
The internal rate of return is the discount rate that makes the net present value of a series of cash flows equal to zero. It measures the annualised return of an investment with regular, periodic cash flows.
Enter cash flows separated by commas, with outflows as negative and inflows as positive. The first value is usually the initial investment. The tool solves for the rate using Newton's method.
IRR assumes periodic cash flows at equal intervals. For irregular timings, use the XIRR calculator.
