How To Calculate Irr On Investment

What is IRR and Why it Matters

Internal Rate of Return (IRR) is a metric used to evaluate the profitability of an investment. It represents the annualized effective compounded return rate that would result in the net present value of the investment being equal to zero.

IRR is crucial because it helps investors compare the expected returns of different investments, regardless of their size or duration.

Formula & Methodology

The IRR formula is based on the net present value (NPV) of the cash flows. The IRR is the discount rate at which the NPV of the cash flows equals zero.

The calculation involves an iterative process, starting with an initial guess and refining it until the NPV is zero.
