What is one of the limitations of the IRR method?

The limitation of the Internal Rate of Return (IRR) method is that it does not fully account for the timing of cash flows. While IRR calculates the rate at which the net present value of cash flows becomes zero, it treats all cash flows as if they were received at the same point in time, which can lead to misleading conclusions about the profitability of an investment.

In practice, cash flows occur over time, and the value of future cash flows is less than that of cash flows received today due to the time value of money. IRR can sometimes misrepresent investment opportunities, especially if cash flows vary significantly over the investment period. Consequently, an investment with a higher IRR may not necessarily be preferable if it means that cash inflows happen at different times compared to another investment with a lower IRR but more favorable cash flow timing.

Understanding this limitation is crucial for making informed investment decisions, as relying solely on IRR could lead to overlooking the greater financial implications associated with cash flow timings.
