The Internal Rate of Return (IRR) is a financial metric that is used to calculate the profitability of an investment. It represents the annual rate of return that is expected to be earned on a project or investment, assuming that the expected future cash flows are reinvested at the IRR rate. The IRR is widely used in capital budgeting and investment analysis to determine the viability of a proposed project or investment. It helps investors and decision-makers to compare the expected return from different investments and choose the one with the highest return.
The IRR is calculated as the discount rate that makes the present value of future cash inflows equal to the initial investment. If the IRR is higher than a required rate of return, then the investment is considered to be viable and profitable. If the IRR is lower than the required rate of return, then the investment is considered to be less profitable and may not be worth pursuing.
It's important to note that IRR assumes that the cash flows generated by the investment are reinvested at the same rate, which may not always be accurate in real-world situations. In such cases, other metrics such as net present value (NPV) or modified internal rate of return (MIRR) may be used to get a more realistic picture of an investment's profitability.
