## Definition of 'IRR Rule'

The internal rate of return (IRR) rule is a method of capital budgeting used to evaluate the profitability of an investment. It is calculated by finding the discount rate that makes the net present value (NPV) of an investment equal to zero. The IRR rule states that an investment should be accepted if its IRR is greater than the company's cost of capital, and rejected if its IRR is less than the cost of capital.

The IRR rule is a popular method of capital budgeting because it is easy to understand and implement. However, it has some limitations. First, the IRR rule does not take into account the time value of money. Second, the IRR rule can be misleading when comparing investments with different cash flow patterns.

Despite its limitations, the IRR rule is a useful tool for evaluating the profitability of an investment. It is important to understand the limitations of the IRR rule before using it to make investment decisions.

The IRR rule can be used to compare investments with different cash flow patterns. However, it is important to note that the IRR rule does not take into account the time value of money. This means that an investment with a higher IRR may not necessarily be more profitable than an investment with a lower IRR.

To illustrate this point, consider two investments with the following cash flows:

* Investment A: $100 today, $100 in one year, and $100 in two years

* Investment B: $100 in one year, $200 in two years, and $300 in three years

The IRR of Investment A is 10%, and the IRR of Investment B is 15%. However, Investment B is more profitable than Investment A because it has a higher NPV. The NPV of Investment A is $93.46, and the NPV of Investment B is $115.87.

This example shows that the IRR rule can be misleading when comparing investments with different cash flow patterns. In this case, Investment B is the better investment, even though it has a lower IRR.
