Interpreting Ratios and Writing a Report for ACCA Financial Accounting

Updated 11 October 2026 · Fact-checked

Interpreting ratios means explaining what the numbers say about performance, liquidity, efficiency and risk. Compare each ratio with a prior year or similar entity, state the change, give a likely reason, and link related ratios. In the exam, choose the answer that fits all the evidence, not one ratio alone.

Understand Interpreting Ratios and Writing a Report

A ratio on its own tells you almost nothing. A gross margin of 30% is neither good nor bad until you know last year's margin, the industry norm, or a competitor's figure. Interpretation is the skill of turning a calculated number into a useful judgement.

There are two main bases of comparison. Trend analysis compares the same entity across periods. Comparison with others looks at a competitor, an industry average or a budget. Both only work if the figures are calculated the same way and the entities are truly similar.

Ratios work in groups. Profitability, liquidity, efficiency and gearing each look at one angle, and they affect each other. A company that cuts prices may see sales rise but gross margin fall. A company that stretches its payables may show a better cash position but a longer payables period and supplier risk. Always ask what one ratio does to another.

Good commentary follows a simple pattern: state the movement, quantify it, give a reason that fits the facts, and say what it means for the entity. Ratio calculation and interpretation can be examined in both objective test questions and multi-task questions. You answer by selecting, matching or entering answers rather than writing long reports, and your choice should always rest on evidence from the data.

Remember the limits. Ratios use historical figures, can be distorted by different accounting policies, year-end timing, seasonal trading and inflation. They show where to look, not the full answer.

Key formulas to remember

Gross profit margin: Gross profit ÷ Revenue × 100; Shows profit after cost of sales. Falls if prices drop or direct costs rise.
Operating profit margin: Profit before interest and tax (PBIT) ÷ Revenue × 100; In this page, operating margin means PBIT ÷ revenue. Compare with gross margin to spot changes in overheads.
Return on capital employed (ROCE): Profit before interest and tax ÷ (Total assets − Current liabilities) × 100; Capital employed is equity plus non-current liabilities. Also equals PBIT margin × asset turnover, provided you use the same capital employed figure in both ROCE and asset turnover.
Asset turnover: Revenue ÷ Capital employed; Shows how hard assets are worked. ROCE = operating margin (PBIT ÷ revenue) × asset turnover, but only when the same capital employed figure is used in both.
Current ratio: Current assets ÷ Current liabilities; Short-term liquidity. No single ideal figure; depends on the industry.
Quick (acid test) ratio: (Current assets − Inventory) ÷ Current liabilities; Removes inventory as it is the least liquid current asset.
Inventory days: Inventory ÷ Cost of sales × 365; Use year-end inventory unless told to use an average.
Receivables days: Trade receivables ÷ Credit revenue × 365; Use revenue if credit sales are not given.
Payables days: Trade payables ÷ Cost of sales × 365; Use purchases if given.
Gearing: Debt ÷ Equity × 100, or Debt ÷ (Debt + Equity) × 100; State which version you use. Follow the question's definition.
Interest cover: Profit before interest and tax ÷ Finance costs; Shows how easily profit covers interest.
Commentary pattern: Movement → Amount → Reason → Meaning; Use for every point you make.

How to solve Interpreting Ratios and Writing a Report questions

Use this method for any interpretation question, whether you must calculate ratios or draw conclusions from given ones.

1Read the requirement. Note whose view you take (investor, lender, manager) and which areas are asked about.
2Identify the comparison: two years of one entity, or two entities. Check the figures are on the same basis.
3Calculate any missing ratios using the formulas given, or the standard ones. Keep the same method for both periods.
4Spot the biggest movements or differences first. Work out the size of each change, not just its direction.
5Link ratios. Ask: does a margin change explain the ROCE change? Does a longer receivables period explain a weaker current ratio or cash position?
6Give a likely reason from the facts in the question, such as a price cut, new loan or new asset. Do not invent facts.
7State the meaning: is the position improving, worsening, risky or healthy for the user named?
8In objective questions, test each option against every ratio. Remove any option that contradicts one piece of data.

Quickest way: Direction, size, link

When to use it: Use in Section A when you have about three minutes and several ratios to read.

Mark each ratio as up or down between the periods or entities.
Group them: profit, liquidity, efficiency, gearing.
Find the one story that explains most movements, such as falling margin with rising sales.
Check each answer option against the story. Discard any that contradict a single figure.
If calculating, round sensibly and confirm the answer is of the right size before moving on.

Common mistakes in Interpreting Ratios and Writing a Report

Just restating the numbers, such as 'ROCE went from 12% to 10%'.
Students think calculation is the hard part and stop there.
Fix: Add a reason and a meaning every time: why it moved and what it implies for the user.
Treating a higher ratio as always better.
Ratios feel like scores.
Fix: Ask what the user wants. Higher payables days help cash but may harm supplier relations. A very high current ratio may mean idle cash or slow inventory.
Looking at each ratio in isolation.
Ratios are learned one at a time.
Fix: Link them: margin and asset turnover to ROCE, borrowing to gearing and interest cover, receivables and inventory to liquidity.
Comparing entities without checking they are similar.
The numbers look comparable on the page.
Fix: Check size, industry, accounting policies and year-end. Note differences such as one entity renting premises and the other owning them.
Mixing methods, such as year-end inventory in one year and average in the other.
Data is missing for one period.
Fix: Use the same basis for all periods and state it.
Inventing reasons that the data does not support.
Students want to sound insightful.
Fix: Say 'this may be due to' and tie it to information given, or suggest what extra information you would need.

Worked examples

Example 1

A company's figures for two years are: Revenue $800,000 (Year 1) and $1,000,000 (Year 2). Gross profit $240,000 and $270,000. Operating profit $120,000 and $100,000. Here, operating profit is taken as profit before interest and tax (PBIT). Compare margins and comment.

Show the solution

Gross margin Year 1 = 240,000 ÷ 800,000 = 30%.
Gross margin Year 2 = 270,000 ÷ 1,000,000 = 27%.
Operating margin Year 1 = 120,000 ÷ 800,000 = 15%.
Operating margin Year 2 = 100,000 ÷ 1,000,000 = 10%.
Gross margin fell 3 percentage points. Operating margin fell 5 points. The extra 2-point fall comes from overheads rising as a share of revenue.
Overheads (gross profit minus operating profit) rose from $120,000 to $170,000. That is from 15% of revenue (120,000 ÷ 800,000) to 17% (170,000 ÷ 1,000,000), which explains the extra 2-point fall.
Revenue grew 25%, yet operating profit fell by $20,000.
Meaning: growth may have come from price cuts or discounts, and costs were not controlled.

Answer: Gross margin fell from 30% to 27% and operating margin (PBIT ÷ revenue) from 15% to 10%. Sales grew but profitability worsened, probably from lower prices and higher overheads, which needs investigation.

Example 2

Company A and Company B are in the same industry. ROCE: A 20%, B 14%. Operating margin: A 10%, B 14%. Which statement is best supported? (1) B is more profitable at every level. (2) A uses its assets more efficiently, with a lower margin. (3) A has higher margin than B. (4) B has a higher asset turnover than A.

Show the solution

ROCE = operating margin × asset turnover, so asset turnover = ROCE ÷ margin.
Company A: 20% ÷ 10% = 2.0 times.
Company B: 14% ÷ 14% = 1.0 times.
Option 1 is wrong: A has the higher ROCE.
Option 3 is wrong: A's margin is 10%, lower than B's 14%.
Option 4 is wrong: B's turnover is 1.0, below A's 2.0.
Option 2 fits: A has the lower margin but double the asset turnover.

Answer: Option 2: A earns a higher ROCE through much stronger asset turnover (2.0 times against 1.0), despite a lower margin.

Exam tips

In multiple response questions, read the number of answers required and test every option against all the data before choosing.
Check which ratio definition the question gives and use it. Do not switch to your preferred version.
Use the link between operating margin, asset turnover and ROCE to explain differences between entities quickly.
When asked about a specific user, such as a lender, focus on gearing, interest cover and liquidity rather than shareholder returns.
For number entry answers, recompute once if time allows and check that the unit, such as days or percent, matches the requirement.

Interpreting Ratios and Writing a Report: frequently asked questions

How do I write ratio analysis commentary in ACCA FA?

Use the pattern: movement, amount, reason, meaning. For example, state that receivables days rose from 40 to 55, suggest slacker credit control, and say this strains cash. Keep each point short and tied to the data.

How do I compare two companies using ratios?

Calculate the same ratios on the same basis for both. Then check they are comparable in size, industry and accounting policies. Explain differences using links, such as margin against asset turnover.

Is a higher ratio always better?

No. It depends on the ratio and the user. A higher gearing figure may mean more risk, while very high inventory days may mean slow sales or obsolete stock.

Do I need to write full reports in the FA exam?

FA is a computer-based objective exam, so you mostly select, match or enter answers rather than write long text. The commentary method still helps you choose the right option quickly.
