Understanding the Accounting Rate of Return Calculator

The accounting rate of return (ARR) is a financial metric used to evaluate the profitability of an investment. It measures the average annual net income generated by an investment as a percentage of the initial investment cost. Calculating the ARR can help investors and businesses make informed decisions about their investment opportunities.

What is ARR?

ARR, also known as the average rate of return, is a simple yet powerful tool in financial analysis. It provides a quick snapshot of the potential return on investment (ROI) for a project or investment opportunity. By comparing the ARR of different projects, investors can prioritize and select the most profitable ones.

What is the Accounting Rate of Return formula?

The formula to calculate the ARR is straightforward:

ARR = Average Annual Net Income / Initial Investment Cost

The average annual net income is calculated by dividing the total net income over a specified period by the number of years in that period. The initial investment cost refers to the total cost of acquiring and setting up the investment.

How to calculate ARR

To calculate the ARR, follow these steps:

1. Determine the net income generated by the investment over a specific period.
2. Identify the initial investment cost.
3. Divide the net income by the number of years in the period to obtain the average annual net income.
4. Divide the average annual net income by the initial investment cost.
5. Multiply the result by 100 to convert it to a percentage.

ARR Calculation – an example

Let's consider a hypothetical scenario where a company invests $100,000 in a new project. The project generates a net income of $20,000 per year for five years. To calculate the ARR:

1. The net income over the five-year period is $20,000 × 5 = $100,000.
2. The initial investment cost is $100,000.
3. The average annual net income is $100,000 / 5 = $20,000.
4. The ARR is $20,000 / $100,000 = 0.2.
5. Multiply 0.2 by 100 to convert it to a percentage: 0.2 × 100 = 20%.

How to calculate Accounting Rate of Return in Excel?

Excel is a powerful tool that can simplify financial calculations, including the accounting rate of return. To calculate the ARR in Excel:

1. Enter the net income figures in a column.
2. Use the Excel formula =AVERAGE to find the average annual net income.
3. Divide the average annual net income by the initial investment cost.
