Internal Rate of Return (IRR)

Internal Rate of Return (IRR) is a financial metric used to evaluate the profitability of an investment or project. It represents the Discount Rate at which the Net Present Value (NPV) of all Cash Flows (both incoming and outgoing) from an investment equals zero. In simpler terms, it is the rate at which an investor can expect to break even on an investment over time.

IRR is often used in Capital Budgeting to compare the profitability of different investments. A higher IRR indicates a more attractive investment opportunity. When evaluating projects, if the IRR exceeds the required rate of return (or hurdle rate), the project may be considered viable.

Example: Consider a project that requires an initial investment of $10,000 and is expected to generate Cash Flows of $2,500 per year for five years. The IRR is the rate that makes the following equation true:

0 = -10,000 + 2,500/(1+IRR) + 2,500/(1+IRR)² + 2,500/(1+IRR)³ + 2,500/(1+IRR)⁴ + 2,500/(1+IRR)⁵

In this case, calculating the IRR might yield an IRR of approximately 12.2%, meaning that if the required rate of return is below this percentage, the project is likely a good investment.

Case: A company is considering two projects, A and B. Project A has an IRR of 15% while Project B has an IRR of 10%. If the company’s required rate of return is 12%, Project A would be preferred over Project B because it exceeds the required rate, indicating a higher potential return on investment.
