internal rate of return (IRR) One of the two discounted cash flow (DCF) techniques (the other is net present value or NPV) used in comparative appraisal of investment proposals where the flow of income varies over time. IRR is the average annual return earned through the life of an investment and is computed in several ways. Depending on the method used, it can either be the effective rate of interest on a deposit or loan, or the discount rate that reduces to zero the net present value of a stream of income inflows and outflows.
While the internal rate of return (IRR) assumes the cash flows from a project are reinvested at the IRR, the modified IRR assumes that positive cash flows are reinvested at the firm's cost of capital, and the initial outlays are financed at the firm's financing cost.or example, say a two-year project with an initial outlay of $195 and a cost of capital of 12%, will return $121 in the first year and $131 in the second year. To find the IRR of the project so that the net present value (NPV) = 0: NPV = 0 = -195 + 121/(1+ IRR) + 131/(1 + IRR) 2 NPV = 0 when IRR = 18.66%.
