Accounting Rate of Return (ARR): Definition & Examples

Businesses use Accounting Rate Of Return (ARR) to calculate what their expected ROI will be. Learn more about this important metric.

Accounting Rate of Return (AIS) Definition

The Accounting Rate of Return (ARR) is used to calculate the expected return on an investment and it’s a very important metric for businesses and investors.

Unlike other measures that might consider cash flows or market factors, the ARR focuses on accounting profits to assess the viability of an investment.

An Example Of An Accounting Equation

Consider a manufacturing company, Industrial Pioneers. Here’s how AIS might be implemented:

  1. Collecting Data: They capture all transactions related to sales, purchases, payroll, and more.
  2. Storing Data: A centralized database securely houses all this information.
  3. Processing Data: Through automated calculations, they analyze profits, expenses, and other financial metrics.
  4. Communicating Data: Financial reports are generated and shared with management, investors, and regulatory bodies.

The AIS allows Industrial Pioneers to manage their financial landscape with precision and agility.

Unlike other measures that might consider cash flows or market factors, the ARR focuses on accounting profits to assess the viability of an investment.

Here’s how ARR is calculated:

ARR = Average Annual Profit / Initial Investment

Let’s break down the components:

  1. Average Annual Profit: This is the net profit expected to be generated by the investment on an annual basis, often calculated by taking the sum of all expected profits over the investment’s life and dividing it by the number of years.
  2. Initial Investment: This refers to the total amount of capital initially invested in the project or asset.

The result is a percentage that gives an indication of the expected annual return on the investment. The ARR serves as a handy tool for businesses to make investment decisions, but it’s more than just a simple formula:

  • Simplicity: The ARR is straightforward to calculate, utilizing readily available accounting information.
  • Profit Focus: Unlike other metrics that may rely on cash flows, ARR uses profit figures, aligning closely with a company’s financial reporting.
  • Breadth of Application: It can be applied to various investments, from purchasing new machinery to launching a new product line.

However, it’s essential to note that the ARR has limitations, particularly since it does not take into account the time value of money, which can be a critical aspect of investment decision-making.

Key Insights

  • ARR allows companies to compare different investment opportunities, aiding in the selection process.
  • By focusing on profitability, ARR offers insights into the potential risk and reward of an investment.
  • It’s crucial to understand that ARR doesn’t consider cash flow timing or the project’s risk, making supplementary analysis often necessary.

An Example of ARR

Imagine a company, GreenTech Innovations, considering investing in a new recycling machine. Here’s how they might use ARR:

  • Average Annual Profit: $10,000
  • Initial Investment: $50,000
  • The ARR would be: ARR = $10,000 / $50,000 = 20%

This would mean that GreenTech Innovations expects a 20% return on their investment annually.


Is ARR suitable for all types of investments?

ARR is most applicable to projects with consistent profits over time. Its simplicity may not capture complex investments with varying cash flows.

How does ARR differ from other investment metrics?

Unlike metrics like the Internal Rate of Return (IRR), ARR focuses solely on accounting profits, not cash flows or the time value of money.

Can ARR be used alone for investment decisions?

While useful, ARR should ideally be used in conjunction with other metrics to provide a comprehensive view of an investment’s attractiveness.
