Key Takeaways The internal rate of return IRR rule states that a project or investment should be pursued if its IRR is greater than the minimum required rate of return, also known as the hurdle rate.
The IRR Rule helps companies decide whether or not to proceed with a project. A company may not rigidly follow the IRR rule if the project has other, less tangible, benefits. Compare Accounts. The offers that appear in this table are from partnerships from which Investopedia receives compensation.

A situation in which the internal rate of return for a project has more than one value. The internal rate of return is the present value of cash flows that will result in a project breaking even; multiple rates of return occur when one calculates cash inflows and cash outlows in the internal rate of return.
A net cash flow stream will have multiple IRRs when it includes more than one sign change. When the calculated IRR is higher than the true reinvestment rate for interim cash flows, the measure will overestimate—sometimes very significantly—the annual equivalent return from the project. The formula assumes that the company has additional projects, with equally attractive prospects, in which to invest the interim cash flows.
Moreover, since IRR does not consider cost of capital, it should not be used to compare projects of different duration. Last but not least, in the case of positive cash flows followed by negative ones and then by positive ones, the IRR may have multiple values. When cash flows of a project change sign more than once, there will be multiple IRRs; in these cases NPV is the preferred measure. In the case of positive cash flows followed by negative ones and then by positive ones, the IRR may have multiple values.
In this case a discount rate may be used for the borrowing cash flow and the IRR calculated for the investment cash flow. This applies for example when a customer makes a deposit before a specific machine is built. In this case it is not even clear whether a high or a low IRR is better. Examples of this type of project are strip mines and nuclear power plants, where there is usually a large cash outflow at the end of the project.
Multiple internal rates of return : As cash flows of a project change sign more than once, there will be multiple IRRs. NPV is a preferable metric in these cases. When a project has multiple IRRs, it may be more convenient to compute the IRR of the project with the benefits reinvested.
It has been shown that with multiple internal rates of return, the IRR approach can still be interpreted in a way that is consistent with the present value approach provided that the underlying investment stream is correctly identified as net investment or net borrowing.
Apparently, managers find it easier to compare investments of different sizes in terms of percentage rates of return than by dollars of NPV. IRR, as a measure of investment efficiency may give better insights in capital constrained situations. However, when comparing mutually exclusive projects, NPV is the appropriate measure. It is used in capital budgeting to rank alternative investments of equal size.
Firstly, IRR assumes that interim positive cash flows are reinvested at the same rate of return as that of the project that generated them. The IRR therefore often gives an unduly optimistic picture of the projects under study. Generally, for comparing projects more fairly, the weighted average cost of capital should be used for reinvesting the interim cash flows.
Secondly, more than one IRR can be found for projects with alternating positive and negative cash flows, which leads to confusion and ambiguity. MIRR finds only one value. Where n is the number of equal periods at the end of which the cash flows occur not the number of cash flows , PV is present value at the beginning of the first period , and FV is future value at the end of the last period.
The formula adds up the negative cash flows after discounting them to time zero using the external cost of capital, adds up the positive cash flows including the proceeds of reinvestment at the external reinvestment rate to the final period, and then works out what rate of return would cause the magnitude of the discounted negative cash flows at time zero to be equivalent to the future value of the positive cash flows at the final time period.
Let take a look at one example. If an investment project is described by the sequence of cash flows: Year 0: , year 1: , year 2: , year 3: IRR can be Privacy Policy.
