Accounting Rate of Return (ARR): Unveiling Profitability

The accounting rate of return (ARR), also known as the average rate of return (ARR), is a financial ratio that measures the profitability of an investment by dividing the average annual profit by the average investment. It expresses the return as a percentage of the investment, offering a simple yet effective method to assess the attractiveness of various investment projects. This method is particularly useful for businesses needing a quick and easily understandable measure of return.

Key Aspects of ARR Calculation:

The calculation of ARR involves two key components:

1. Average Annual Profit: This represents the average net income generated by the investment over its projected lifespan. It's calculated by summing the projected annual net profits and dividing by the number of years.
2. Average Investment: This is the average amount of capital invested throughout the project's life. For projects with a constant investment, this is simply the initial investment. However, for projects with varying investment levels over time, an average must be calculated.

Discussion: Delving Deeper into ARR Calculation

To accurately determine ARR, a precise calculation of both average annual profit and average investment is crucial. Let's examine each component:

Average Annual Profit: This requires accurate profit projections for each year of the investment's life. These projections should account for all relevant costs and revenues, including depreciation and taxes. The sum of these annual profits is then divided by the number of years to obtain the average annual profit. The accuracy of this figure directly influences the reliability of the ARR.

Average Investment: This component accounts for the initial investment and any subsequent investments or disinvestments during the project's life. In simpler cases where investment remains constant, the initial investment value is used. However, in more complex scenarios with changes in investment, the calculation becomes more involved. Common methods include calculating the simple average of the beginning and ending investment or using a weighted average considering the duration of each investment level.

Accounting Rate of Return Calculation: A Step-by-Step Guide

The ARR is calculated using the following formula:

ARR = (Average Annual Profit / Average Investment) * 100

Let's illustrate this with an example:

Example: ARR Calculation for a New Machine

Suppose a company is considering investing in a new machine costing $100,000. The machine is expected to generate the following annual profits over its five-year lifespan:

• Year 1: $20,000
• Year 2: $25,000
• Year 3: $30,000
• Year 4: $25,000
• Year 5: $20,000

Step 1: Calculate the Average Annual Profit

Total Profit = $20,000 + $25,000 + $30,000 + $25,000 + $20,000 = $120,000

Average Annual Profit = $120,000 / 5 = $24,000

Step 2: Calculate the Average Investment

Assuming a constant investment (no additional investments or disposals), the average investment is equal to the initial investment.

Average Investment = $100,000

Step 3: Calculate the ARR

ARR = ($24,000 / $100,000) * 100 = 24%

This indicates that the investment is projected to yield an average annual return of 24% based on the projected profits.

Limitations of ARR:

While ARR offers a simple and intuitive method for investment appraisal, it does have limitations:

• Ignores the Time Value of Money: ARR doesn't account for the fact that money received today is worth more than money received in the future.
• Relies on Accounting Profits: Accounting profits can be manipulated through accounting policies, potentially distorting the ARR.
• Doesn't Consider Project Duration: ARR doesn't explicitly consider the lifespan of a project, leading to potential misinterpretations when comparing projects of differing lengths.

Advantages of ARR:

Despite its limitations, ARR remains a valuable tool:

• Simplicity: ARR is easy to calculate and understand, making it accessible to non-financial professionals.
• Intuitive: The percentage return facilitates easy comparison across different investment projects.
• Useful for Screening: ARR can be used as a preliminary screening tool to eliminate obviously unattractive investment options.

FAQ

Introduction: This section addresses frequently asked questions about the accounting rate of return.

Questions:

1. Q: What is the difference between ARR and other investment appraisal techniques like Net Present Value (NPV)?

   A: Unlike ARR, NPV considers the time value of money, making it a more sophisticated but complex method for assessing investment viability. NPV accounts for the fact that money received today is worth more than money received in the future. ARR does not.

2. Q: How do I handle depreciation when calculating average annual profit for ARR?

   A: Depreciation expense should be deducted from the annual revenue to arrive at the net profit before calculating the average annual profit. Different depreciation methods (straight-line, declining balance, etc.) will yield different results, influencing the final ARR.

3. Q: Can ARR be used to compare projects with different lifespans?

   A: While technically possible, comparing projects with vastly different lifespans using ARR can be misleading. Longer-lived projects might show a lower ARR than shorter-lived projects simply because of the longer period considered.

4. Q: What is considered a "good" ARR?

   A: A "good" ARR is relative to the company's cost of capital and the risk associated with the investment. A higher ARR compared to the cost of capital and a similar level of risk generally implies a more attractive investment.

5. Q: What are some common errors made when calculating ARR?

   A: Common errors include using incorrect profit figures (excluding taxes or depreciation), incorrectly calculating the average investment, and overlooking the limitations of ARR.

6. Q: How does ARR help in capital budgeting decisions?

   A: ARR provides a quick and simple way to rank projects according to their profitability, helping businesses to prioritize and select the most promising investment opportunities within budget constraints.

Summary: The ARR offers a useful initial assessment tool in capital budgeting, helping companies filter investments based on their average annual returns. However, it’s essential to acknowledge its limitations, particularly its failure to account for the time value of money.

Transition: While ARR provides a valuable perspective, a comprehensive investment analysis should incorporate other techniques like NPV and IRR for a more holistic approach.

Tips for Effective ARR Analysis:

Introduction: This section provides practical tips for effectively utilizing ARR in investment analysis.

Tips:

1. Accurate Forecasting: Ensure reliable revenue and expense projections for each year of the investment's life.
2. Consistent Accounting Methods: Use consistent accounting methods throughout the calculation process to avoid biases.
3. Consider Risk: Don't rely solely on ARR. Assess the risk profile of the investment alongside the ARR.
4. Compare with Alternatives: Compare the ARR of different investment options to make an informed choice.
5. Complement with other Methods: Use ARR in conjunction with other investment appraisal methods like NPV and IRR.
6. Sensitivity Analysis: Perform sensitivity analysis to determine how changes in key assumptions impact the ARR.
7. Consider qualitative factors: Don’t base your decisions solely on ARR. Incorporate qualitative factors like market conditions, competitive landscape and strategic fit.

Summary: By following these tips, businesses can effectively leverage ARR to enhance their investment decision-making process.
