What is Internal Rate of Return (IRR)?
The Internal Rate of Return (IRR) is a financial metric used to measure the profitability of an investment. In simple terms, IRR is the discount rate that makes the net present value (NPV) of future cash flows equal to zero.
For investors, IRR is an indicator of the expected annual growth rate of an investment. A higher IRR means higher profitability.
Formula:
While the mathematical formula for IRR is complex, it essentially solves for the discount rate where:
NPV = 0
That’s why most professionals prefer using an IRR Calculator rather than manually solving it.
