Ratio Analysis and Interpretation of Financial Statements for ACCA SBR

Updated 11 October 2026 · Fact-checked

Ratio analysis turns financial statements into measures of profitability, liquidity, efficiency, gearing and investor return. In SBR you rarely just calculate. You compare ratios across years or with peers, explain the causes using the scenario, check comparability and accounting policies, and conclude for a named user.

Understand Ratio Analysis and Interpretation of Financial Statements

A ratio relates one figure to another so you can judge performance without being misled by size. Revenue of $50 million means little alone. A margin of 12% can be compared with last year or with a competitor.

Ratios fall into groups. Profitability shows how well the business earns from sales and capital (gross margin, operating margin, ROCE). Liquidity shows if it can pay short-term debts (current and quick ratios). Efficiency shows how well it uses assets and working capital (asset turnover, inventory, receivable and payable days). Gearing shows reliance on debt and the ability to service it (gearing, interest cover). Investor ratios show returns to shareholders (EPS, P/E, dividend cover, dividend yield).

The difference between gross margin and operating margin matters. Gross margin shows the direct profit on what is sold, so it points to selling prices and cost of sales. Operating margin also deducts distribution costs, administrative expenses and other operating costs, so it points to overheads and cost control. If gross margin is stable but operating margin falls, look at overheads, not pricing.

SBR tests interpretation. A ratio is only a starting point. You must explain why it moved, using the facts in the scenario: a new acquisition, a change in accounting policy, a lease, a impairment, a revaluation, a currency movement or an unusual item. Trend analysis over several years shows direction. Comparison with a competitor or industry shows relative position, but only if accounting policies, year ends, definitions and business models are comparable.

Also remember the limits. Statements are historical, use judgement and estimates, and can be affected by earnings management. Ratios ignore non-financial matters such as customer satisfaction, staff, and sustainability. Good answers say what the ratios suggest, what else you need, and what the user should conclude.

Key rules to remember

Gross margin: Gross profit ÷ Revenue × 100; Shows direct profitability. Check changes in price, mix and cost of sales.
Operating margin: Profit from operations ÷ Revenue × 100; Define profit from operations clearly (before finance costs and tax) and use the same definition every year.
Return on capital employed (ROCE): Profit before interest and tax ÷ (Total assets − Current liabilities) × 100; Capital employed is usually equity plus non-current liabilities. State your definition.
Asset turnover: Revenue ÷ Capital employed; ROCE = operating margin × asset turnover when the same profit and capital figures are used.
Current ratio: Current assets ÷ Current liabilities; No universal ideal figure. Compare with the sector and the prior year.
Quick ratio: (Current assets − Inventory) ÷ Current liabilities; Removes inventory as the least liquid current asset.
Inventory days: Inventory ÷ Cost of sales × 365; Use closing or average inventory consistently.
Receivable days: Trade receivables ÷ Credit revenue × 365; Use total revenue if credit sales are not given.
Payable days: Trade payables ÷ Cost of sales (or credit purchases) × 365; Purchases is better if given.
Gearing: Debt ÷ Equity × 100, or Debt ÷ (Debt + Equity) × 100; State which version you use. Decide whether lease liabilities are included as debt.
Interest cover: Profit before interest and tax ÷ Finance costs; Shows how many times profit covers interest. Low cover signals risk.
Earnings per share: Profit attributable to ordinary shareholders ÷ Weighted average ordinary shares; Basic EPS under IAS 33.
Price/earnings ratio: Market price per share ÷ EPS; Reflects market expectations of growth and risk.
Dividend cover: Profit attributable to ordinary shareholders ÷ Ordinary dividends; Or EPS ÷ dividend per share.

How to solve Ratio Analysis and Interpretation of Financial Statements questions

Use this method for any ratio or performance question. It keeps you on interpretation, which is where the marks are.

1Read the requirement. Note who the user is (investor, lender, board, potential acquirer) and what decision they face.
2Scan the scenario for events that distort the numbers: acquisitions, disposals, policy changes, impairments, leases, unusual items, currency.
3Choose a small set of relevant ratios, usually profitability, liquidity or efficiency, and gearing, plus an investor ratio if needed. State each formula briefly.
4Calculate for each year or entity. Keep definitions identical and show workings in a short table-like list.
5Spot the biggest movements and work out the likely cause by linking one ratio to another (for example margin down while asset turnover up).
6Explain each point: what the ratio shows, why it changed, and whether it is good or bad for this user.
7Comment on comparability and limits: policies, year ends, size, timing, estimates, and missing non-financial information.
8Conclude with a clear view and a recommendation or further information needed. Add professional skills: balanced, sceptical, concise.

Quickest way: Three-point ratio comment under time pressure

When to use it: Use when time is short or the question asks for a brief assessment with only a few ratios.

Calculate only 6 to 8 ratios that cover profitability, liquidity or efficiency, and gearing.
For each key ratio write three short parts: the figure and movement, the reason from the scenario, the effect on the user.
Spend the last minutes on one comparability or policy caveat and a one-sentence conclusion.
If you run out of time, give the conclusion first and support it with the strongest two ratios.

Common mistakes in Ratio Analysis and Interpretation of Financial Statements

Listing calculated ratios with little or no comment.
Calculating feels safe and gives visible work.
Fix: Allow at least as much time for explanation as for calculation. Each ratio needs a cause and a consequence.
Using inconsistent definitions between years or companies.
Students rush and pick different profit or capital figures.
Fix: State the formula once and apply it identically everywhere. Show the figures you used.
Giving generic reasons not linked to the scenario.
Students memorise standard comments such as 'efficient credit control'.
Fix: Tie each movement to a scenario fact such as an acquisition, a new lease or a price cut. If the cause is uncertain, say it is a possible explanation.
Treating gross margin and operating margin as the same.
Both are profit as a percentage of revenue.
Fix: Use gross margin for pricing and direct costs and operating margin for overhead control. Compare the two movements.
Ignoring comparability and accounting policy differences.
Students assume reported numbers are directly comparable.
Fix: Check revaluation versus cost, lease treatment, capitalised development costs, year ends and one-off items. Adjust if the data allows, or say what bias exists.
Calling a ratio good or bad without reference to the user or sector.
Students rely on rules of thumb such as a current ratio of 2.
Fix: Judge against the prior year, peers and the user's needs. A lender focuses on interest cover and gearing, a shareholder on returns and growth.

Worked examples

Example 1

Alpha Co reports the following for Year 2 and Year 1 ($m). Year 2: revenue 600, gross profit 150, operating profit 60, finance costs 15, capital employed 400. Year 1: revenue 500, gross profit 140, operating profit 65, finance costs 8, capital employed 350. Calculate gross margin, operating margin, ROCE and interest cover for both years, and comment for a lender.

Show the solution

Gross margin Year 2: 150 ÷ 600 = 25.0%. Year 1: 140 ÷ 500 = 28.0%.
Operating margin Year 2: 60 ÷ 600 = 10.0%. Year 1: 65 ÷ 500 = 13.0%.
ROCE Year 2: 60 ÷ 400 = 15.0%. Year 1: 65 ÷ 350 = 18.6% (18.57%).
Interest cover Year 2: 60 ÷ 15 = 4.0 times. Year 1: 65 ÷ 8 = 8.1 times (8.125).
Comment: revenue grew 20% but margins fell. Gross margin fell 3 percentage points, and operating margin fell by the same 3 points, so overheads grew roughly in line with revenue. The fall is mainly in direct costs or pricing, for example discounting to win sales.
ROCE fell because profit fell while capital employed rose by $50m. Growth has not yet produced a return.
Interest cover halved from 8.1 to 4.0 times because finance costs almost doubled and profit fell. This suggests more borrowing.

Answer: Gross margin 25.0% (28.0%), operating margin 10.0% (13.0%), ROCE 15.0% (18.6%), interest cover 4.0 times (8.1 times). For a lender, the trend is weakening: profit has fallen as debt rose. Cover of 4.0 times is still adequate, but the lender should ask why margins fell, check covenants and the plans for further borrowing.

Example 2

Beta Co and Gamma Co operate in the same sector. Beta: revenue $800m, operating profit $96m, capital employed $480m. Gamma: revenue $800m, operating profit $96m, capital employed $640m. Beta carries property at cost; Gamma has revalued its property upwards. Compare ROCE and asset turnover and explain why the comparison needs care.

Show the solution

Beta operating margin: 96 ÷ 800 = 12.0%. Gamma: 96 ÷ 800 = 12.0%.
Beta asset turnover: 800 ÷ 480 = 1.67 times. Gamma: 800 ÷ 640 = 1.25 times.
Beta ROCE: 96 ÷ 480 = 20.0%. Gamma: 96 ÷ 640 = 15.0%. Check: 12.0% × 1.67 = 20.0% and 12.0% × 1.25 = 15.0%.
Margins are identical, so the ROCE gap comes entirely from asset turnover. Gamma generates less revenue per dollar of capital.
Comparability: Gamma's revaluation raises capital employed (via the revaluation surplus in equity) and so lowers ROCE and asset turnover without any change in operations. Beta's cost basis understates its asset base and flatters its ratios.
Gamma may also have higher depreciation on the revalued asset, which would reduce its profit, but here the profits are equal, so note this as a point to investigate.
To compare fairly, restate Gamma's property to cost, or Beta's to current value, if information is available.

Answer: Beta ROCE 20.0% and asset turnover 1.67 times, Gamma ROCE 15.0% and asset turnover 1.25 times, with identical operating margins of 12.0%. Beta looks more efficient, but part of the gap is likely due to Gamma's revaluation. The conclusion should be cautious until both are put on the same measurement basis.

Exam tips

Always identify the user and the decision. Link your conclusion to them.
Use the scenario clues. Examiners place events in the data to explain the ratio movements. Missing them loses marks.
State your formula and any assumption (for example, whether leases are in debt). Marks are awarded for a sensible, consistent approach.
Do not spend most of your time calculating. Choose focused ratios and leave time for evaluation.
Show professional skills: give a balanced view, challenge the data quality, and say what further information you would request.

Ratio Analysis and Interpretation of Financial Statements: frequently asked questions

How many ratios should I calculate in an SBR question?

Calculate only those that answer the requirement, usually six to eight across profitability, liquidity or efficiency, gearing and investor measures. More ratios cost time and rarely earn extra marks. Marks come mostly from interpretation.

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

Gross margin shows profit after direct costs of sales, so it reflects pricing and product costs. Operating margin also deducts overheads such as distribution and administration, so it reflects cost control. Comparing movements in both shows where a profit change arose.

How do I deal with comparability of ratios?

Check accounting policies, year ends, size, business models and one-off items. Examples are cost versus revaluation, lease treatment and capitalised development. State the effect on the ratio, adjust if the data allows, and treat the comparison with caution.

Do I need to memorise ideal ratio values?

No. There is no universal ideal for most ratios. Judge them against the prior year, competitors or the sector, and against the needs of the user. State your reasoning.
