Accounting Rate of Return Calculator

Use our Accounting Rate of Return (ARR) Calculator to make better decisions. This tool helps managers and investors measure return from an investment. It shows the average annual profit earned from an asset. It compares this profit with the original investment cost. It also gives a simple “Yes/No” signal for project approval.

What is Accounting Rate of Return (ARR)?

The Accounting Rate of Return is also called the Simple Rate of Return. It helps measure how profitable an investment can be. It uses accounting profit instead of cash flow. It also focuses on Net Operating Income.

ARR answers a simple question. It shows how much average annual profit a project can earn. It then compares that profit with the money invested. Many people use ARR for early project checks. It uses common accounting numbers from financial statements. These include depreciation and net income.

The Formula and Logic

Our calculator uses the standard academic method, which provides the most accurate view of capital usage over time.

• Step 1: Calculate Annual Depreciation
  Equation: (Initial Cost – Scrap Value)/Life Years = Annual Depreciation
• Step 2: Calculate Average Annual Profit
  Equation: Annual Cash Flow – Annual Depreciation = Accounting Profit
• Step 3: Calculate Average Investment
  Equation: (Initial Cost + Scrap Value)/2 = Average Investment
  Why divide by 2? Because the book value of the asset declines from its initial cost down to its scrap value over time. On average, you only have half the capital tied up.
• Step 4: Calculate ARR
  Equation: (Avg Annual Profit/Avg Investment) x 100 = ARR%

Clarifying the Advanced Parameters

• Scrap/Residual Value: This is the estimated value of the asset at the end of its useful life. For example, if you can sell a machine for $5,000 after five years, that amount reduces your depreciation expense. This also pushes your ARR higher.
• Annual Cash Flow: This refers to the net cash inflows from revenue minus operating expenses. It does not include depreciation.
• Target/Hurdle Rate: This is the minimum ARR your company will accept. If the calculated ARR falls below this number, the company typically rejects the project.

Global Investment Facts: ARR Usage by Region

United States (USA)

US finance teams often use ARR as a sanity check alongside DCF models. US GAAP puts strong emphasis on correct depreciation schedules. Most US corporate finance teams look for an ARR that beats the company’s current Return on Assets (ROA).

England/United Kingdom (UK)

UK firms follow IFRS standards and use ARR widely for smaller capital projects. Running a full DCF model for these projects is often unnecessary. A common benchmark in UK manufacturing sits between 15% and 20%. This reflects the higher cost of capital in unpredictable markets.

Canada (CAN)

Canadian resource companies in mining and forestry use ARR to evaluate heavy equipment purchases. These assets often hold high scrap values due to residual metal worth. This makes the ARR calculation very sensitive to the scrap value field in our calculator.

Australia (AUS)

Australian businesses often use ARR to determine internal performance bonuses. Managers tend to choose projects with high ARRs. This directly improves the company’s reported net profit. Higher net profit also drives share prices on the ASX.

India (IND)

In India, ARR is a standard metric for Chartered Accountants and commerce students. Indian small and medium enterprises prefer ARR over IRR in practice. It aligns better with bank loan interest rates. For example, if a machine earns an ARR of 15% and the bank charges 10% interest, the project makes financial sense.

Frequently Asked Questions

Why use ARR instead of IRR?

ARR is easier to calculate and easier to explain to non-financial managers. It connects directly to the company’s profit and loss statement. IRR, on the other hand, is a theoretical concept that focuses on cash flow.

What is the main limitation of ARR?

ARR ignores the time value of money. It treats a dollar earned in Year 1 the same as a dollar earned in Year 5. This makes ARR less reliable than NPV or IRR for long-term projects.

Should I use initial investment or average investment?

Our calculator uses average investment because it measures capital employed more accurately. Using initial investment in the denominator makes the ARR appear lower than it actually is.

Does depreciation affect ARR?

Yes, and it makes a big difference. Higher depreciation reduces your accounting profit, which lowers your ARR. However, depreciation also reduces your tax bill. Advanced analysts usually factor this in.

What is a “good” ARR?

A company typically accepts a project when its ARR exceeds the cost of capital plus a risk premium. For most companies, an ARR above 12% to 15% signals a healthy investment.
