Profitability Ratios for ACCA Financial Reporting

Updated 11 October 2026 · Fact-checked

Profitability ratios measure how well a business turns resources into profit. The main ones are ROCE, gross, operating and net margins, asset turnover and return on equity. Calculate each from the financial statements, compare with prior years or peers, and explain the cause of any change, not just the number.

Understand Profitability Ratios

Profitability ratios answer one question: how much profit does the business earn, relative to sales or to the money invested in it? Users such as investors, lenders and managers all want the answer, but they look at different ratios.

Margins compare profit with revenue. Gross margin uses gross profit, so it shows the effect of selling prices and cost of sales. Operating margin uses profit from operations (profit before finance costs and tax), so it adds the effect of distribution and administrative costs. Net margin uses profit after tax and includes finance costs and tax.

Return ratios compare profit with the money used to earn it. ROCE (return on capital employed) shows the return on all long-term finance, both equity and debt. Return on equity (ROE) shows the return to the shareholders only.

Asset turnover shows how much revenue each unit of capital employed generates. It links to ROCE: ROCE = operating margin × asset turnover. So ROCE can rise because margins improve, because assets are used harder, or both. Examiners love this link, because it lets you explain why ROCE moved.

A ratio on its own means little. Compare it with the prior year, a competitor or the industry. Then give reasons, such as price changes, cost control, new assets bought late in the year, or a change in sales mix.

Key rules to remember

Return on capital employed (ROCE): ROCE = Profit before interest and tax ÷ (Total assets − Current liabilities) × 100%; Capital employed equals equity plus non-current liabilities. Use the same definition every year and state it.
Gross profit margin: Gross profit ÷ Revenue × 100%; Shows the effect of selling prices and cost of sales.
Operating profit margin: Profit from operations (before finance costs and tax) ÷ Revenue × 100%; Compare with gross margin to see whether overheads are under control.
Net profit margin: Profit after tax ÷ Revenue × 100%; Affected by finance costs and tax as well as operations. Some questions use profit before tax, so state your choice.
Asset turnover: Revenue ÷ Capital employed (times); Same capital employed figure as in ROCE. Some questions use total assets or net assets, so state it.
ROCE link: ROCE = Operating profit margin × Asset turnover; Works exactly only if the same profit and capital employed figures are used throughout.
Return on equity (ROE): Profit after tax ÷ Total equity × 100%; Profit attributable to owners of the parent over equity attributable to them is used in group questions.

How to solve Profitability Ratios questions

Use this method for any profitability question, whether the task is calculation, interpretation or both.

1Read the requirement. Note who the user is and whether you must compare years or companies.
2Choose the definitions you will use for profit and capital employed. Write them down briefly and apply them consistently.
3Pull the figures from the statement of profit or loss and the statement of financial position. Check which year's figures you are using.
4Calculate each ratio for every year or entity. Round to one decimal place and show the workings.
5Compare: state the direction and size of each change, such as margin down from 20.0% to 17.5%.
6Explain the reasons. Use the ROCE link: did margin or asset turnover drive the change? Use clues from the scenario.
7Conclude for the user. Say whether performance has improved or worsened overall and note any limits, such as year-end asset purchases or different policies.

Quickest way: Margins and turnover first, then ROCE check

When to use it: Use this in multiple-choice questions or when time is short in a Section C interpretation.

Calculate operating margin and asset turnover first. They are simple divisions.
Multiply them to check ROCE. If it matches a direct calculation, your figures are consistent.
Compare gross margin with operating margin. If gross margin is steady but operating margin falls, overheads are the cause.
In MCQs, check which profit figure and capital employed the question defines before dividing.
Write one sentence per ratio in the form: change, cause, implication.

Common mistakes in Profitability Ratios

Using profit after interest in ROCE.
Students take the last profit figure on the statement.
Fix: ROCE uses profit before interest and tax, because capital employed includes debt. Add back finance costs to profit before tax.
Using only equity as capital employed.
Confusing ROCE with ROE.
Fix: Capital employed is total assets less current liabilities, which equals equity plus non-current liabilities.
Confusing gross margin with operating margin.
Both are margins on revenue, so the labels get mixed.
Fix: Gross uses gross profit only. Operating uses profit after distribution and administrative costs but before finance costs and tax.
Stating the ratio changed without explaining why.
Students stop once the calculation is done.
Fix: Always give a cause, supported by the scenario, and say what it means for the user.
Inconsistent definitions between years or companies.
Figures are picked in a hurry.
Fix: Fix your definitions before calculating and use them for every period.
Ignoring year-end timing of asset purchases or revaluations.
Students treat capital employed as an average over the year.
Fix: Note that closing capital employed may include assets that have not yet earned profit, which depresses ROCE and asset turnover. Revaluations also raise capital employed without raising profit.

Worked examples

Example 1

Alpha Ltd has revenue of $800,000, gross profit of $240,000, profit from operations of $96,000, finance costs of $16,000 and tax of $20,000. Total assets are $700,000, current liabilities are $100,000 and equity is $440,000. Calculate gross margin, operating margin, net margin, ROCE, asset turnover and ROE.

Show the solution

Gross margin = 240,000 ÷ 800,000 = 30.0%.
Operating margin = 96,000 ÷ 800,000 = 12.0%.
Profit before tax = 96,000 − 16,000 = 80,000. Profit after tax = 80,000 − 20,000 = 60,000. Net margin = 60,000 ÷ 800,000 = 7.5%.
Capital employed = 700,000 − 100,000 = 600,000. ROCE = 96,000 ÷ 600,000 = 16.0%.
Asset turnover = 800,000 ÷ 600,000 = 1.33 times.
Check: 12.0% × 1.333 = 16.0%.
ROE = 60,000 ÷ 440,000 = 13.6%.

Answer: Gross margin 30.0%, operating margin 12.0%, net margin 7.5%, ROCE 16.0%, asset turnover 1.33 times, ROE 13.6%.

Example 2

Beta Ltd had the following results. Year 1: revenue $500,000, gross profit $150,000, operating profit $75,000, capital employed $300,000. Year 2: revenue $600,000, gross profit $174,000, operating profit $72,000, capital employed $400,000. Calculate and explain the change in ROCE.

Show the solution

Year 1 gross margin = 150,000 ÷ 500,000 = 30.0%. Year 2 = 174,000 ÷ 600,000 = 29.0%.
Year 1 operating margin = 75,000 ÷ 500,000 = 15.0%. Year 2 = 72,000 ÷ 600,000 = 12.0%.
Year 1 asset turnover = 500,000 ÷ 300,000 = 1.67 times. Year 2 = 600,000 ÷ 400,000 = 1.5 times.
Year 1 ROCE = 75,000 ÷ 300,000 = 25.0%. Year 2 ROCE = 72,000 ÷ 400,000 = 18.0%.
Check Year 2: 12.0% × 1.5 = 18.0%.
Gross margin fell by only one point, but operating margin fell by three points. So overheads grew faster than revenue.
Asset turnover fell, so the extra $100,000 of capital has not yet produced proportionate sales. It may have been invested late in the year.

Answer: ROCE fell from 25.0% to 18.0%. Revenue grew by 20% but operating profit fell, because overheads rose sharply. The larger capital base also generated less revenue per $1 invested, with asset turnover down from 1.67 to 1.5 times.

Exam tips

Write your definition of capital employed and profit in one line before calculating. Markers give credit for clear, consistent definitions.
In Section C, spend more time on explanation than arithmetic. Each point needs a change, a cause and a consequence.
Use the ROCE = margin × asset turnover link to structure your answer, and say which factor drove the change.
Use the scenario clues, such as new stores, price cuts, a revaluation or a loan taken, to support your reasons.
In objective questions, read which profit figure is defined and check units and percentages before choosing.

Profitability Ratios: frequently asked questions

How do I calculate ROCE in ACCA FR?

Divide profit before interest and tax by capital employed, then multiply by 100. Capital employed is total assets less current liabilities, which is equity plus non-current liabilities.

What is the difference between gross profit margin and operating profit margin?

Gross margin uses gross profit, which is revenue less cost of sales. Operating margin uses profit after distribution and administrative costs but before finance costs and tax. A gap that widens between them points to rising overheads.

How are asset turnover and ROCE related?

ROCE equals operating profit margin multiplied by asset turnover, if you use the same profit and capital employed figures. It lets you explain whether a change in ROCE came from margins, asset use or both.

What is the return on equity formula?

Return on equity is profit after tax divided by total equity, multiplied by 100. It shows the return to shareholders. In group questions, use profit and equity attributable to the owners of the parent.
