How to Calculate Accounting Rate of Return (ARR): A Comprehensive Guide for Investors and Financial Analysts

What is Accounting Rate of Return (ARR)?

The Accounting Rate of Return (ARR) is a financial metric used to evaluate the profitability of an investment. It represents the average net income earned on an investment, expressed as a percentage of its average book value. This metric is particularly useful in capital budgeting because it provides a straightforward way to compare different investment opportunities.
ARR is calculated based on the net income generated by an investment and its average book value over its lifespan. Unlike other metrics like the Internal Rate of Return (IRR) or Net Present Value (NPV), ARR does not take into account the time value of money, making it simpler but also less comprehensive.

How to Calculate Accounting Rate of Return

Step-by-Step Process

Calculating ARR involves a few straightforward steps:
1. Calculate the Average Annual Profit:
– Project the estimated increase in annual revenues.
– Subtract the increase in annual costs, including non-cash charges for depreciation.
– This will give you the net profit before taxes.
2. Calculate the Average Investment Cost:
– Take the initial book value of the investment.
– Add the book value at the end of its life.
– Divide this sum by two to get the average book value.
3. Apply the ARR Formula:
– Use the formula: ( \text{ARR} = \frac{\text{Average Annual Profit}}{\text{Average Investment}} \times 100\% )

Example Calculation

Let’s consider an example to illustrate this process:
Suppose you are considering purchasing a new machine for $100,000. Here are some projected figures:
– Annual increase in revenues: $30,000
– Annual increase in costs (excluding depreciation): $10,000
– Annual depreciation: $20,000
1. Calculate Average Annual Profit:
– Net profit before taxes = $30,000 (revenue) – $10,000 (costs) – $20,000 (depreciation) = $0
However, since depreciation is a non-cash expense:
– Adjusted net profit = $30,000 – $10,000 = $20,000
2. Calculate Average Investment Cost:
– Initial book value = $100,000
– End-of-life book value (assuming it depreciates fully) = $0
– Average book value = ($100,000 + $0) / 2 = $50,000
3. Apply the ARR Formula:
– ARR = ($20,000 / $50,000) * 100% = 40%

Components of the ARR Calculation

Average Annual Profit

To determine the average annual profit, you need to project the estimated increase in annual revenues and subtract the increase in annual costs. This includes adjustments for non-cash expenses like depreciation. For instance:
– If your annual revenue increase is $30,000 and your annual cost increase is $10,000 with an additional $20,000 in depreciation,
– Your net profit before taxes would be adjusted by adding back the depreciation since it’s not a cash expense.

The average investment cost is calculated by taking the initial book value of the investment plus its book value at the end of its life and dividing by two. This gives you an average over its lifespan.

Advantages and Disadvantages of ARR

Advantages

The Accounting Rate of Return has several advantages that make it a popular choice among investors and financial analysts:
– Simplicity: ARR is easy to understand and calculate compared to more complex metrics like IRR or NPV.
– Quick Evaluation: It provides a quick snapshot of an investment’s profitability without needing sophisticated financial models.

Disadvantages

Despite its simplicity, ARR has some significant limitations:
– Neglects Time Value of Money: Unlike other metrics, ARR does not account for the time value of money, which can lead to inaccurate comparisons between investments with different lifespans.
– Focus on Net Income: ARR focuses on net income rather than cash flow, which can be misleading if there are significant non-cash items involved.
– Subjective Adjustments: The calculation can be affected by subjective adjustments such as depreciation methods chosen by management.

Using ARR in Financial Decision-Making

When using ARR in financial decision-making, it’s important to compare the calculated ARR with the company’s minimum required rate of return. Here’s how you can do it:
1. Compare with Minimum Required Rate: If the calculated ARR exceeds the company’s minimum required rate of return (often referred to as the cost of capital), it may indicate that the investment is profitable enough to pursue.
2. Consider Other Metrics: While ARR provides valuable insights into profitability, it should not be used in isolation. Other financial metrics such as IRR, NPV, and payback period should also be considered for a comprehensive evaluation.
