What is the difference between required rate of return and irr

Internal rate of return : Internal rate of return is the rate at which the NPV of an investment equals 0. One advantage of the IRR method is that it is very clear and easy to understand. In other words, an investment is considered acceptable if its internal rate of return is greater than an established minimum acceptable rate of return or cost of capital. Most analysts and financial managers can understand the opportunity costs of a company.

If the IRR exceeds this rate, then the project provides financial accretion. However, if the rate of an investment is projected to be below the IRR, then the investment would destroy company value. IRR is used in many company financial profiles due its clarity for all parties. The IRR method also uses cash flows and recognizes the time value of money. Compared to payback period method, IRR takes into account the time value of money. This is because the IRR method expects high interest rate from investments.

In addition, the internal rate of return is a rate quantity, it is an indicator of the efficiency, quality, or yield of an investment. This is in contrast with the net present value, which is an indicator of the value or magnitude of an investment. The first disadvantage of the IRR method is that IRR, as an investment decision tool, should not be used to rate mutually exclusive projects but only to decide whether a single project is worth investing in.

In addition, IRR assumes reinvestment of interim cash flows in projects with equal rates of return the reinvestment can be the same project or a different project. Therefore, IRR overstates the annual equivalent rate of return for a project whose interim cash flows are reinvested at a rate lower than the calculated IRR. This presents a problem, especially for high IRR projects, since there is frequently not another project available in the interim that can earn the same rate of return as the first project.

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. Subscribe for unlimited access. Create an account to read 2 more. Financial analysis.

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.
