What is Internal Rate of Return?

Internal Rate of Return (IRR) is the discount rate that makes the net present value (NPV) of all cash flows from a project equal to zero. It represents the expected annualized rate of return for an investment. IRR is widely used in capital budgeting to compare the profitability of different investments. The Modified IRR (MIRR) addresses some limitations of traditional IRR by assuming reinvestment at a different rate.

How to use

Enter your initial investment, select a cash flow pattern (even, growing, or custom), specify the number of years and annual cash flows. You can also add terminal value and specify reinvestment/financing rates for MIRR calculation. The calculator displays IRR, MIRR, NPV, and provides investment recommendations.
