Calculate The Accounting Rate of Return

The Accounting Rate of Return (ARR) is a financial metric used to evaluate the profitability of an investment or business venture. Unlike the Internal Rate of Return (IRR), which considers cash flows, ARR is based on accounting income and expenses, providing a more straightforward measure of financial performance.

What is the Accounting Rate of Return?

The Accounting Rate of Return is calculated by dividing the accounting income by the average investment. It provides a simple ratio that shows how much profit is generated per dollar invested, based on accounting figures rather than cash flows.

This metric is particularly useful for comparing the performance of different investments or projects when cash flow timing is not a major concern. It's commonly used in business valuation and investment analysis.

How to Calculate the Accounting Rate of Return

To calculate the Accounting Rate of Return, follow these steps:

Determine the accounting income for the period
Calculate the average investment during the period
Divide the accounting income by the average investment
Multiply by 100 to express the result as a percentage

The result is the Accounting Rate of Return, expressed as a percentage. A higher percentage indicates better financial performance relative to the investment.

Accounting Rate of Return Formula

Formula

Accounting Rate of Return (ARR) = (Accounting Income / Average Investment) × 100

Where:

Accounting Income - The net income reported on the income statement
Average Investment - The average amount of capital invested during the period

Note

The average investment is typically calculated as (Beginning Investment + Ending Investment) / 2.

Example Calculation

Let's say a company has an accounting income of $50,000 and an average investment of $250,000 over a year. Here's how to calculate the Accounting Rate of Return:

Calculation

ARR = ($50,000 / $250,000) × 100 = 20%

In this example, the Accounting Rate of Return is 20%, meaning the company generated $20 in profit for every $100 invested.

Interpretation of Results

The Accounting Rate of Return helps investors and business owners understand the profitability of their investments or business operations. Here's how to interpret different ARR values:

ARR Range	Interpretation
Below 10%	Poor financial performance, may indicate inefficiency or high costs
10% - 20%	Moderate performance, may need improvement
20% - 30%	Good performance, indicates effective use of resources
Above 30%	Excellent performance, may indicate high profitability or efficient operations

While ARR provides valuable insights, it should be considered alongside other financial metrics for a comprehensive evaluation of investment performance.

FAQ

What is the difference between Accounting Rate of Return and Internal Rate of Return?

The Accounting Rate of Return uses accounting income and expenses, while the Internal Rate of Return considers cash flows. ARR is simpler and doesn't account for timing of cash inflows and outflows.

How is average investment calculated?

Average investment is typically calculated as (Beginning Investment + Ending Investment) / 2. This provides a midpoint measure of capital invested during the period.

What does a high Accounting Rate of Return indicate?

A high ARR indicates that the investment or business operation is generating significant profits relative to the amount invested, suggesting good financial performance.
