What Is the Accounting Rate of Return (ARR)?
The Accounting Rate of Return (ARR), also known as the Average Accounting Return (AAR) or the Average Rate of Return, is a financial metric used to evaluate the profitability of an investment or project. It is a simple method that calculates the average annual accounting profit generated by an investment relative to its initial cost.
It’s important to note that ARR has some limitations and drawbacks:
- Focus on Accounting Profits: ARR uses accounting profit figures, which may not accurately reflect cash flows or consider the time value of money.
- Ignores Time Value of Money: ARR does not consider the concept of the time value of money, which is a critical factor in evaluating investment decisions.
- Subjectivity: The choice of accounting profit and the determination of useful life can be subjective and vary between analysts.
- Ignores Cash Flows: Cash flows are essential in investment analysis, as they represent the actual inflows and outflows of cash.
- No Clear Decision Criterion: Unlike other methods like Net Present Value (NPV) or Internal Rate of Return (IRR), ARR does not provide a clear decision criterion for whether an investment should be undertaken.
Due to these limitations, the Accounting Rate of Return is considered a less sophisticated method of investment appraisal compared to more advanced techniques like NPV, IRR, or Payback Period. As a result, it’s often recommended to use ARR in conjunction with other investment evaluation methods to make well-informed decisions.
Understanding the Accounting Rate of Return (ARR)
Let’s break down the concept of Accounting Rate of Return (ARR) further to ensure a clear understanding:
- Purpose: ARR is used to assess the potential profitability of an investment or project by comparing the average accounting profit generated over the investment’s life to the initial cost of the investment.
- Calculation:
- Calculate the average annual accounting profit, usually by taking the sum of the accounting profits over a certain period (often the useful life of the investment) and dividing it by the number of years.
- Divide the average annual accounting profit by the initial investment and multiply by 100 to express the result as a percentage.
- Components:
- Average Annual Accounting Profit: This is the average net income earned from the investment over its useful life. Net income is calculated by deducting all relevant expenses, taxes, and depreciation from the revenues generated by the investment.
- Initial Investment: This is the total amount of money invested in the project, including all costs associated with acquiring and setting up the asset.
- Pros:
- Simplicity: ARR is easy to calculate and understand, making it useful for quick preliminary evaluations.
- Utilization of Accounting Data: It uses readily available accounting information, making it accessible.
- Cons:
- Excludes Time Value of Money: ARR does not account for the fact that money received or spent in the future is not equivalent to money received or spent today.
- Ignores Cash Flows: ARR doesn’t consider the actual cash inflows and outflows, which are crucial in evaluating an investment’s financial performance.
- Subjectivity: The choice of accounting profit and useful life can be subjective and impact the ARR calculation.
- Lacks Clear Decision Rule: ARR doesn’t provide a specific benchmark for decision-making like some other methods (e.g., a required rate of return or a specific payback period).
- Use Cases:
- ARR might be useful for initial screening of investment options or for projects with relatively short lifespans and stable cash flows.
- It can be used in conjunction with other methods, such as Net Present Value (NPV) and Internal Rate of Return (IRR), to provide a more comprehensive view of an investment’s potential.
- Limitations:
- ARR should not be used as the sole criterion for investment decisions due to its limitations. It’s important to consider the time value of money, cash flows, and other relevant factors.
- For accurate assessments, it’s often better to use more sophisticated methods like NPV or IRR, which take into account the time value of money and cash flows.
The Formula for ARR
The formula for calculating the Accounting Rate of Return is as follows:
- ARR = (Average Annual Accounting Profit) / (Initial Investment) × 100%
Where:
- Average Annual Accounting Profit: This is typically calculated by taking the average of the accounting profits (net income) generated by the investment over its useful life.
- Initial Investment: The total amount of money invested in the project or asset.
The result is expressed as a percentage, representing the average annual return on the initial investment based on the accounting profits.
How to Calculate the Accounting Rate of Return (ARR)
Let’s walk through an example of calculating the Accounting Rate of Return (ARR) for a hypothetical investment.
Example Scenario: Company XYZ is considering investing in a new project that involves purchasing and installing a piece of manufacturing equipment. The equipment costs $200,000 and is expected to have a useful life of 5 years. The projected net income (accounting profit) generated by the equipment over these 5 years is as follows:
- Year 1: $40,000
- Year 2: $45,000
- Year 3: $50,000
- Year 4: $55,000
- Year 5: $60,000
Calculate the Accounting Rate of Return (ARR):
- Step 1: Calculate Average Annual Accounting Profit Average = \frac{40,000 + 45,000 + 50,000 + 55,000 + 60,000}{5} = \frac{250,000}{5} = $50,000
- Step 2: Calculate Initial Investment Initial Investment = $200,000
- Step 3: Apply the ARR Formula ARR = 50,000/200,000×100%=0.25×100%=25%
In this example, the Accounting Rate of Return (ARR) for the investment in the manufacturing equipment is 25%. This means that, on average, the investment is expected to generate a 25% return on the initial investment based on accounting profits over the 5-year period.
Accounting Rate of Return vs. Required Rate of Return
Accounting Rate of Return (ARR) and Required Rate of Return (RRR) are two distinct financial concepts used in investment analysis, but they serve different purposes and focus on different aspects of an investment.
Let’s compare them:
Accounting Rate of Return (ARR):
- Purpose: ARR is used to assess the potential profitability of an investment by comparing the average annual accounting profit generated by the investment to the initial cost of the investment.
- Calculation: ARR is calculated as the average annual accounting profit divided by the initial investment, expressed as a percentage.
- Focus: ARR is concerned with the accounting profits (net income) generated by the investment and does not consider the time value of money or cash flows.
- Simplicity: ARR is relatively simple to calculate and provides a quick initial assessment of an investment’s profitability.
- Limitations: ARR ignores important financial concepts like the time value of money and cash flows, and it lacks a clear decision criterion for comparing investments.
Required Rate of Return (RRR):
- Purpose: RRR, also known as the hurdle rate or minimum acceptable rate of return, is the minimum rate of return that an investor or company requires from an investment to compensate for the risk associated with it.
- Calculation: The RRR is based on a variety of factors, including the investor’s cost of capital, the risk-free rate, market risk premiums, and the specific risk of the investment. It’s typically expressed as a percentage.
- Focus: RRR is concerned with the investor’s required return and considers factors like the time value of money, inflation, and risk.
- Decision Making: RRR is used as a benchmark for evaluating investments. If an investment’s expected return (e.g., using methods like NPV or IRR) is higher than the RRR, it may be considered acceptable. If it’s lower, the investment might be rejected.
- Flexibility: The RRR can vary based on factors such as the company’s risk tolerance, the nature of the investment, and prevailing economic conditions.
In summary, ARR is a simple method that focuses on comparing accounting profits to initial investment, while RRR is a more comprehensive concept that considers the investor’s required return based on factors like risk and time value of money. RRR is often used as a decision-making tool to evaluate whether an investment meets the investor’s minimum criteria, whereas ARR is a basic indicator of potential profitability but lacks the sophistication of considering these important financial considerations.
Advantages and Disadvantages of the Accounting Rate of Return (ARR)
The Accounting Rate of Return (ARR) has its own set of advantages and disadvantages when used as a method for evaluating investments. Let’s explore these:
Advantages of ARR:
- Simplicity: ARR is easy to understand and calculate, making it accessible to a wide range of users, including those without a strong financial background.
- Utilization of Accounting Data: ARR uses readily available accounting information, which can be convenient and efficient for preliminary evaluations.
- Quick Assessment: It provides a quick initial assessment of an investment’s potential profitability, allowing for a rapid screening of projects.
- Useful for Comparisons: ARR can be useful for comparing projects or investments based on their accounting profitability, especially when the investments have similar risk profiles.
Disadvantages of ARR:
- Excludes Time Value of Money: ARR does not consider the time value of money, which means it fails to account for the fact that a dollar received in the future is worth less than a dollar received today.
- Ignores Cash Flows: ARR focuses solely on accounting profits and ignores cash flows, which are crucial for understanding an investment’s actual financial impact.
- Subjectivity: The choice of accounting profit and the determination of the investment’s useful life can be subjective, leading to variations in ARR calculations.
- Lacks Decision Criterion: ARR does not provide a clear benchmark for decision-making. There is no universally accepted standard for what constitutes an acceptable ARR, making it difficult to determine whether an investment is worthwhile based solely on its ARR.
- Inconsistent with Investment Goals: ARR may lead to suboptimal investment decisions if the goal is to maximize shareholder wealth, as it doesn’t account for factors like risk and the time value of money.
- Doesn’t Consider Reinvestment: ARR assumes that the accounting profits are not reinvested, which can be unrealistic for many investments.
Given these limitations, ARR is often considered a less robust method of investment appraisal compared to other techniques such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period. While it can provide a simple snapshot of potential profitability, it is recommended to use ARR alongside other methods to ensure a comprehensive and accurate evaluation of investment opportunities.
