Using the Internal Rate of Return (IRR) as a measure for investment alternatives is particularly favored because it provides a clear acceptance or rejection criterion. IRR represents the discount rate that makes the net present value (NPV) of an investment equal to zero. This characteristic allows decision-makers to compare the IRR of a project against the required rate of return or a benchmark return, which is essential for evaluating whether to proceed with an investment. If the IRR exceeds the benchmark rate, the investment is generally accepted; if not, it is rejected.

This clarity in decision-making is one of the essential advantages of using IRR, enabling investors to make informed choices based on a straightforward threshold. It simplifies the evaluation process, as stakeholders can easily determine the viability of multiple projects based on an absolute rate of return.

While other factors may also be relevant, such as the ease of calculation or consideration of cash flows, the distinctive feature of IRR is its definitive criterion for acceptance or rejection, making it a valuable tool in capital budgeting and investment analysis.
