What is a fundamental principle of IRR analysis?

The fundamental principle of Internal Rate of Return (IRR) analysis is that it equates the benefits and costs of a project by identifying the rate at which the net present value (NPV) of cash flows from an investment equals zero. In other words, IRR is the discount rate that makes the present value of the project's expected cash inflows equal to the present value of its outflows. This characteristic allows decision-makers to assess the profitability of potential projects by comparing the IRR to the required rate of return or the cost of capital. When the IRR exceeds the required rate, the project is considered a worthwhile investment.

While factors like budgeting, accounting profits, and liquidity are relevant to investment analysis, they are not the primary focus of IRR analysis. IRR directly connects the timing and magnitude of cash flows rather than merely assessing budgetary concerns, relying solely on accounting profits, or determining liquidity. These aspects may play a role in the broader financial analysis of a project, but they do not capture the essence of what IRR aims to evaluate regarding project feasibility and comparative returns.
