In the world of financial planning and business management, measuring the performance of an investment is crucial for making informed decisions. One popular and easy-to-understand metric used by businesses, analysts, and students alike is the Accounting Rate of Return (ARR).
To help simplify this process, we’ve developed an intuitive Accounting Rate of Return Calculator. This powerful yet user-friendly tool allows you to calculate the ARR based on registered profit, years of investment, initial investment, working capital, and scrap value—instantly delivering clear and actionable insights.
What is the Accounting Rate of Return (ARR)?
Accounting Rate of Return (ARR) is a financial ratio that measures the expected profitability of an investment. It is calculated by dividing the average annual accounting profit by the average investment.
Unlike other return metrics such as internal rate of return or net present value, ARR focuses purely on accounting information rather than cash flows. It provides a quick way to evaluate whether an investment is likely to be worthwhile from an accounting standpoint.
ARR is usually expressed as a percentage and is commonly used in capital budgeting decisions, particularly in initial investment evaluations.
ARR Formula
The formula for ARR used in this calculator is:
ARR = (Average Annual Profit / Average Investment) × 100
Where:
- Average Annual Profit = Registered Profit / Years of Investment
- Average Investment = (Initial Investment + Working Capital + Scrap Value) / 2
This formula provides the percentage return on the average capital invested during the project’s lifetime.
How to Use the Accounting Rate of Return Calculator
Our tool makes calculating ARR effortless. Follow these steps:
- Enter Registered Profit ($)
This is the total profit the project is expected to generate over its life. - Enter Years of Investment
Indicate the total duration of the investment in years. - Enter Initial Investment ($)
Provide the upfront cost required to start the project. - Enter Working Capital ($)
Input the funds needed to support the daily operations of the project. - Enter Scrap Value ($)
Include the residual value of the investment at the end of its life. - Click the “Calculate” Button
The calculator instantly displays the ARR in percentage form.
Example Calculation
Let’s walk through a practical example using the calculator:
- Registered Profit = $120,000
- Years of Investment = 4
- Initial Investment = $150,000
- Working Capital = $30,000
- Scrap Value = $20,000
Step 1:
Average Annual Profit = 120,000 / 4 = $30,000
Step 2:
Average Investment = (150,000 + 30,000 + 20,000) / 2 = 200,000 / 2 = $100,000
Step 3:
ARR = (30,000 / 100,000) × 100 = 30%
So, the Accounting Rate of Return for this investment is 30%.

Benefits of Using ARR
- Simplicity: Easy to understand and apply without advanced financial knowledge.
- Comparison-Friendly: Useful for comparing different projects or investments.
- Accounting-Based: Relies on readily available profit and investment data.
- Time-Saving: Avoids the need for discount rate estimations used in other methods.
Limitations of ARR
While ARR is helpful, it’s important to be aware of its limitations:
- Ignores Time Value of Money: It doesn’t discount future profits, unlike NPV or IRR.
- Based on Accounting Profit: Doesn’t reflect actual cash flow, which can vary significantly.
- No Risk Adjustment: ARR doesn’t consider the variability or uncertainty of returns.
- Misleading for Uneven Profits: Assumes average profit, which may not be accurate in fluctuating revenue scenarios.
When to Use ARR
ARR is most effective when:
- You want a quick, high-level evaluation of a project.
- You’re comparing projects of similar duration and risk profile.
- You have limited access to detailed cash flow data.
- Simplicity and ease of interpretation are more important than financial depth.
