## What Is The Difference Between Internal Rate Of Return And Return On Investment?

The internal rate of return (IRR) definition is a guideline for evaluating whether a project of investment is worth following for investors. And it’s is a metric used in capital budgeting to estimate the return for potential investments.

The return on investment (ROI) is another performance measure that’s used to assess the efficiency of an investment. Or it can be used to compare the efficiency of several investments.

What is the difference between IRR and ROI?

## Internal rate of return

IRR provides you with an annual growth rate and takes into consideration the time value of money.

IRR is the rate of return that equates the present value of an investment’s expected gain with the present value of its costs.

IRR is used for measuring long-term investments with different cash inflows and outflows.

IRR is especially useful in assessing alternative investments like real estate and hedge funds.

IRR is ideal for analysing capital budgeting projects comparing potential rates of annual return over a period of time.

## Return on investment

ROI indicates the growth of investment from beginning to end.

ROI is a performance measure that’s simple to calculate.

ROI is the percentage difference between the current value of an investment and the original value.

ROI figures will vary depending on figure included as earnings and expenses.

ROI faces challenges that can make long-term investment forecasts less meaningful.

ROI assumes that all cash flows are received at the end of the investment.

## Internal rate of return formula

The formula used for calculating IRR sets the net present value (NPV) to zero. Net present value is the difference between the present value of cash inflows and outflows over a period of time and is used in corporate budgeting.

T is the number of time periods

Ct is the total net cash flow during period t

CO are the total initial investment costs

The initial investment is always negative as it represents the outflow and each subsequent cash flow could be negative or positive depending on what cash the project delivers or if it needs a capital injection in the future.

Due to the nature of the formula, IRR can’t easily be calculated analytically and software programmed to carry out these calculations is often used.

## Modified rate of return

The modified internal rate of return (MIRR) assumes that positive cash flows are reinvested at the business’s cost of capital and that the initial outlays are financed by the business. This results in a more accurate reflection of the cost and profitability of a project.

Access to software programmes will enable calculations of MIRR using details of cash flows, financing rates, and reinvestment rates. This financial measure will help to determine the attractiveness of an investment and can also be used to compare different investments. It’s basically a modification of IRR which resolves some issues associated with that measure.

Calculating MIRR considers three key variables:

• The future value of positive cash flow discounted at the reinvestment rate
• The present value of negative cash flows discounted at the financing rate
• The number of periods

The view is that MIRR provides a more realistic picture of the return on an investment project compared to IRR with the MIRR being commonly lower, possibly returning only one solution.
