ARR, or Accounting Rate of Return, is an important tool in capital budgeting that helps assess how profitable an investment is over time. It plays a crucial role in assessing long-term projects by focusing on average accounting profit rather than cash flow. In this blog, we explore the full spectrum of advantages and disadvantages of the ARR, helping decision-makers weigh its strengths and limitations before using it in financial analysis.
What Is ARR? Understanding the Meaning and Calculation Method
The Accounting Rate of Return measures a project’s average yearly accounting profit against its average invested amount..
Formula:
ARR = (Average Annual Accounting Profit / Average Investment) × 100%
It’s widely used for its simplicity and accessibility, especially for businesses that prioritize profit-based decision-making.
Importance of ARR in Investment Appraisal
ARR is instrumental in evaluating whether a project meets a company’s return expectations. It allows decision-makers to compare proposed projects with internal benchmarks or the company’s required rate of return. Because it uses accounting data, ARR integrates naturally into financial reporting and performance reviews.
Advantages of the ARR
1. Simplicity and Ease of Calculation
ARR uses standard financial statements, making it easy to calculate and interpret, even for non-finance professionals.
2. Uses Familiar Accounting Data
Since ARR uses accounting profit, companies don’t need to make complex cash flow projections.
3. Focuses on Profitability
ARR highlights how profitable a project is over its lifetime, aligning well with profitability goals.
4. Whole-Project Evaluation
It evaluates performance over the entire project life, providing a complete profitability picture.
5. Benchmarking Performance
ARR enables easy comparison of various investments against a set internal standard or industry rate.
6. Depreciation Accountability
Unlike cash-based methods, ARR accounts for depreciation, offering a more comprehensive evaluation of project profitability.
Disadvantages of the ARR
1. Ignores the Time Value of Money
ARR treats all future profits equally, disregarding when the profits occur—a major limitation in long-term planning.
2. Relies on Accounting Profit, Not Cash Flow
Profit figures may not reflect actual liquidity. ARR doesn’t consider when cash is received or spent.
3. Vulnerable to Accounting Policies
Different accounting treatments can lead to varying ARR values for the same project.
4. No Time-Based Decision Rule
ARR doesn’t provide a clear cutoff point or internal consistency in decision-making.
5. Ignores Risk and Uncertainty
ARR doesn’t adjust for market or project-specific risks, which can distort return expectations.
6. Bias Toward Short-Term Gains
ARR may favor projects that generate higher profits earlier, neglecting projects with long-term value.
7. Limitations When Compared with Discounted Cash Flow Approaches
ARR doesn’t align with discount-based models such as Net Present Value (NPV) or Internal Rate of Return (IRR), which incorporate the time value of money into their analysis.
Common Pitfalls in ARR Usage
- Assumes profits are evenly distributed
- Over-reliance on accounting rules can skew outcomes
- Lack of uniform calculation practices among firms
- Doesn’t adjust for inflation or changing market dynamics
Strategic Adjustments to Improve ARR
1. Modified ARR Using Discounted Profit
Discounting accounting profits helps reflect the time value of money while maintaining the ARR approach.
2. Incremental ARR for Comparisons
Evaluating only the incremental profits of competing projects improves ARR accuracy.
3. Risk-Adjusted ARR
Introduce risk adjustments by using hurdle rates or adjusting projected profits for risk sensitivity.
4. Consistent Accounting Norms
Uniformity in accounting policies ensures valid ARR comparisons across projects.
ARR vs Other Appraisal Metrics
ARR vs Net Present Value (NPV)
NPV considers the time value of money and cash flows, whereas ARR uses average accounting profit.
ARR vs Internal Rate of Return (IRR)
IRR provides a discount rate that sets NPV to zero, while ARR offers a straightforward profitability percentage.
ARR vs Payback Period
Payback period focuses on how quickly the investment is recovered; ARR measures average return.
ARR vs Profitability Index
The Profitability Index relates present value to cost, whereas ARR evaluates annual profit over investment.
Practical Uses of ARR in Business
- Initial screening of project feasibility
- Useful in performance reviews and strategic planning
- Small businesses benefit due to its simplicity
Illustrative ARR Calculation Example
Assume a ₹1,000,000 project generating ₹200,000 average profit annually over 5 years with an average investment of ₹500,000.
ARR = (₹200,000 / ₹500,000) × 100 = 40%
This 40% ARR may be compared to the firm’s required rate of return to evaluate project feasibility.
ARR in Different Industries
In manufacturing, where depreciation is significant, ARR can help reflect profitability better. In service or software industries, where capital expenditure is lower, ARR might be less relevant. Project context matters significantly.
Best Practices When Using ARR
- Use ARR for initial screening, not final decisions
- Combine ARR with DCF metrics like NPV or IRR
- Adjust ARR for risk and timing of profits
- Maintain consistent accounting policies across projects
Key Takeaways: Balancing Advantages and Disadvantages
While ARR offers ease and accessibility, its limitations—chiefly ignoring time value and over-reliance on accounting profit—demand cautious application. It serves best when used in conjunction with more robust methods like NPV and IRR.

Frequently Asked Questions (FAQs)
What ARR percentage is considered favorable?
A good ARR varies by industry, but it should exceed the company’s required rate of return or cost of capital.
Does ARR include the time value of money?
ARR overlooks the impact of when profits are earned, ignoring the time value of money concept. It treats all profits equally regardless of timing.
How does depreciation affect ARR?
Increased depreciation expenses lead to reduced accounting earnings, which in turn diminishes the ARR figure. Different methods can affect ARR calculations significantly.
Is ARR effective for evaluating projects that have varying durations?
Not directly. You must adjust ARR or use methods like equivalent annual annuity to ensure comparability.
Is ARR better than NPV?
ARR is simpler but less accurate. NPV provides better insight by considering time value and actual cash flows.
What’s the difference between ARR and ROI?
ARR focuses on average annual profit over investment; ROI is total profit over total investment.
Should ARR be used alone?
No. It should be used alongside methods like NPV and IRR for complete investment appraisal.
Conclusion
ARR is a useful tool in the investment decision-maker’s toolkit, offering simplicity and clear profitability insights. However, its limitations make it unsuitable as a standalone metric. Tools like Emagia can bridge these gaps, delivering enhanced analytical power and strategic clarity.
