amazon.co.ukA* ratio analysis for AQA 7127 (3.8, 3.17): profitability, liquidity, efficiency, gearing and interest cover calculated from financial statements, with two-year interpretation, stakeholder viewpoints, window dressing and the limitations examiners want evaluated.
Profitability ratios answer one question in three ways: is the business generating adequate return from its sales and from the funds invested in it? The formulas are fixed in the AQA appendix, so formula recall earns nothing by itself - the marks are in calculation accuracy, comparison and causal interpretation.
| Ratio | Formula | What it measures |
|---|---|---|
| Gross profit margin | Gross profit ÷ revenue × 100 | Trading profitability after cost of sales |
| Mark-up | Gross profit ÷ cost of sales × 100 | Percentage added to cost in pricing |
| Operating profit margin | Operating profit ÷ revenue × 100 | Overall cost control after overheads |
| ROCE | Operating profit ÷ capital employed × 100 | Return on all long-term funds (equity + non-current liabilities) |
Formula discipline: use operating profit - not profit for the year - in both the operating margin and ROCE, and capital employed is equity plus non-current liabilities (equivalently, non-current assets plus current assets minus current liabilities). Using the wrong profit or the wrong denominator is the most common calculation error and zeroes the interpretation built on it.
Data (year ended 31 March): 2025 - revenue £900,000, gross profit £315,000, operating profit £90,000, equity £600,000, non-current liabilities £300,000. 2024 - revenue £800,000, gross profit £280,000, operating profit £72,000, equity £550,000, non-current liabilities £300,000.
| Ratio | 2025 | 2024 |
|---|---|---|
| Gross profit margin | 315,000/900,000 = 35.0% | 280,000/800,000 = 35.0% |
| Operating profit margin | 90,000/900,000 = 10.0% | 72,000/800,000 = 9.0% |
| ROCE | 90,000/900,000 = 10.0% | 72,000/850,000 = 8.5% |
Interpretation: the gross margin held at 35%, so trading economics (pricing versus direct costs) were stable. The operating margin improved from 9% to 10% - overheads grew more slowly than sales, evidence of operating leverage. ROCE rose from 8.5% to 10.0%: a better return even though capital employed grew from £850,000 to £900,000. The A* move is the decomposition: ROCE = operating margin × capital turnover (revenue ÷ capital employed). Here 10.0% = 10.0% × 1.00 in 2025, versus 8.5% = 9.0% × 0.94 in 2024 - so the improvement came from both margin and asset productivity, a two-cause explanation that scores above a one-cause answer.
Causes to attach to movements, ready-made for exams. A falling gross margin: price discounting in a competitive market; rising input costs not passed on; inventory losses (theft, obsolescence) inflating cost of sales; or a sales-mix shift towards lower-margin lines. A rising margin: price rises absorbed by customers; cheaper suppliers; better purchasing (bulk discounts); or - the sceptical check - a one-off reclassification. A falling operating margin with a stable gross margin: overhead creep (admin, distribution) outpacing sales; a falling margin with a rising gross margin suggests overheads were cut - a strategy with service-quality consequences worth mentioning. For mark-up, remember its exam use: with mark-up of 25% you can reconstruct cost of sales (100/125 of revenue) in incomplete-records questions - profitability ratios are computational tools, not just commentary.
ROCE invites benchmarking against three yardsticks: the prior year (trend), the industry (is 10% good for this sector?), and the cost of debt (if ROCE exceeds the interest rate on borrowing, gearing magnifies returns to shareholders; if not, it destroys them). That third comparison is the bridge to gearing in section 2 - and a favourite examiner link. When asked to evaluate profitability, resist one-number conclusions: a high margin on tiny revenue is worse than a modest margin on huge revenue, so pair margins with turnover and ROCE with growth. And state the movement in plain words before quantifying: 'ROCE improved by 1.5 percentage points because operating profit grew 25% while capital employed grew only 6%' is an analytical sentence; 'ROCE went up' is not.
Improvement strategies earn evaluation marks when tied to trade-offs. Raise the gross margin by raising prices (risk: volume loss), renegotiating supply (risk: quality), or pushing high-margin lines (risk: alienating existing customers). Improve ROCE by raising margin, increasing capital turnover (sweating the assets: sell idle equipment, outsource), or returning idle capital to investors. Every strategy has a second-order effect on another ratio - price rises may lengthen receivables days; asset disposals cut future capacity - and saying so explicitly is what separates the top band from mid band in AQA's 25-mark Section C questions.
A business prices at a mark-up of 25% on cost. If revenue is £150,000, cost of sales = 150,000 × 100/125 = £120,000 and gross profit = £30,000 (a margin of 20%). In incomplete-records questions this runs in reverse: a trial balance fragment showing revenue £150,000 and a known 25% mark-up implies cost of sales £120,000; any gap between that computed figure and the ledger's cost of sales points to unrecorded purchases, theft or stock losses. Mark-up is therefore not just commentary - it is the input that reconstructs missing figures, which is why the AQA appendix lists it alongside the margins.
Two distortions deserve a reflex. Sales mix: a stable blended gross margin can hide two offsetting movements - higher prices on a shrinking line, lower prices on a booming one - so where mix data is given, comment on the components rather than the blend. One-off items: a disposal profit inside other income lifts the operating margin in the year of sale and vanishes the next; restructuring costs depress one year only. When the question supplies a note ('operating profit includes £25,000 profit on disposal of a warehouse'), strip it out before interpreting, and state that you have done so - examiners reward the explicit adjustment, because it shows you are reading the accounting policies behind the number, not just the number.
Industry benchmarking needs the same care to earn marks. A 35% gross margin is excellent in grocery (high turnover, low margin) and poor in jewellery (low turnover, high margin) - what matters is the combination of margin and capital turnover that produces ROCE, so a low-margin, fast-turning business can out-return a high-margin, slow one. Always ask what a benchmark measures: national averages smear very different business models together; a named competitor of similar scale is better evidence; the business's own plan is the fairest test of management performance. Where the question supplies prior-year data only, use the trend and add that industry norms would sharpen the conclusion - that sentence is itself an analysis mark, and in evaluation questions it becomes the 'further information required' point.
Common calculation errors to drill out: using revenue in the ROCE denominator (that gives asset turnover, not return); averaging capital employed when the question gives one figure (average is only required if both opening and closing are given - follow the data provided); computing payables days on revenue instead of purchases (use cost of sales or credit purchases as directed); and confusing a 35% margin with 35% growth. Set answers out in a small table - ratio, 2025, 2024, movement - because AQA markers credit clear working, and an error in one figure then costs one mark, not the thread of the interpretation built on it.
Liquidity asks whether short-term obligations can be met; efficiency asks how fast working capital turns; gearing asks who financed the business and how risky the structure is. The three interlock - a business can be profitable yet illiquid, liquid yet inefficient, and efficient yet dangerously geared - so AQA rewards answers that connect them.
| Ratio | Formula | Benchmark/guide |
|---|---|---|
| Current ratio | Current assets ÷ current liabilities | ~1.5-2:1 |
| Acid test | (Current assets − inventory) ÷ current liabilities | ~1:1 |
| Inventory turnover | Cost of sales ÷ average inventory (or 365 ÷ inventory days) | Sector-specific |
| Trade receivables days | Trade receivables ÷ credit sales (revenue) × 365 | Compare with credit terms |
| Trade payables days | Trade payables ÷ credit purchases (cost of sales) × 365 | Compare with suppliers' terms |
| Gearing | Non-current liabilities ÷ (equity + non-current liabilities) × 100 | >50% high by convention |
| Interest cover | Operating profit ÷ finance costs | >2-3× comfortable |
2025: inventory £75,000, receivables £110,000, cash £15,000, current liabilities £150,000 (of which payables £120,000), cost of sales £585,000. 2024: inventory £60,000, receivables £80,000, cash £60,000, current liabilities £160,000 (payables £115,000), cost of sales £520,000.
| Ratio | 2025 | 2024 |
|---|---|---|
| Current ratio | 200,000/150,000 = 1.33:1 | 200,000/160,000 = 1.25:1 |
| Acid test | 125,000/150,000 = 0.83:1 | 140,000/160,000 = 0.88:1 |
| Receivables days | 110,000/900,000 × 365 = 45 days | 80,000/800,000 × 365 = 37 days |
| Payables days | 120,000/585,000 × 365 = 75 days | 115,000/520,000 × 365 = 81 days |
| Inventory days | 75,000/585,000 × 365 = 47 days | 60,000/520,000 × 365 = 42 days |
| Working capital cycle | 47 + 45 − 75 = 17 days | 42 + 37 − 81 = −2 days |
Read the story: the current ratio edged up but cash collapsed from £60,000 to £15,000, receivables days stretched by 8 days (looser credit control, or a customer problem), payables days shortened (paying earlier - possibly straining cash or earning early-payment discounts), and inventory moved slower. Net effect: the working capital cycle swung from −2 days (suppliers effectively financed the business) to +17 days the business must fund itself. Liquidity looked stable while its quality worsened - exactly the layered reading AQA's top band rewards. The acid test below 1 is acceptable here only if receivables are collectable; note receivables of £110,000 cover most of the £150,000 current liabilities, so the ratio depends on collection discipline.
Efficiency commentary patterns: receivables days above stated credit terms signal weak credit control or disputed invoices - chasing them releases cash at zero cost; payables days below suppliers' terms may waste discounts, but very long payables days risk supply refusal and signal cash distress to the market; slow inventory ties up cash, incurs storage and risks obsolescence - and under the prudence concept may need writing down to net realisable value, hitting gross profit. Efficiency links to profitability directly: cash trapped in working capital cannot earn ROCE elsewhere; that is the overtrading diagnosis - rapid revenue growth funded by stretching payables and an overdraft, where margins look healthy but the cash cycle runs dry. Spot the symptoms: rising revenue with falling liquidity, payables days rising, ROCE fine but cash negative.
Gearing is the structural risk ratio. In the example above, gearing = 300,000/900,000 = 33% (2025) versus 35% (2024) - falling as equity accumulates. High gearing cuts both ways: with interest cover of 3.0 (90,000/30,000), shareholders are geared for upside if returns on assets exceed the 12% cost of debt implied by 36,000 on 300,000... check the question's given rate - but if operating profit falls by half, cover drops to 1.5 and the business is near the edge. Evaluation points AQA expects: interest is a fixed obligation paid before any dividend; secured lenders take assets on default; high gearing removes flexibility to borrow for opportunities; but debt is often cheaper than equity and interest is tax-deductible, so modest gearing is rational. Never conclude 'gearing is high, therefore bad' without interest cover, cash stability and the purpose of the borrowing (growth funding versus survival refinancing) on the table.
Connect the three families in your conclusions: improving profitability by stretching payables days damages supplier goodwill (qualitative), tightening receivables days improves liquidity but may cost sales, cutting inventory improves the cycle but risks stockouts. The exam's higher-order demand is a recommendation: 'extend the overdraft facility and tighten credit control rather than cut inventory, because...' with figures quoted as evidence. That sentence structure - recommendation, evidence, mechanism - is the template for full marks.
A retailer doubles revenue from £400,000 to £800,000. Gross margin holds at 40%. Inventory rises from £50,000 to £130,000; receivables from £35,000 to £95,000; payables from £45,000 to £130,000; the bank account moves from £10,000 credit to a £60,000 overdraft. Liquidity: current ratio 1.55:1 to 1.30:1; acid test 0.94:1 to 0.71:1. The margins tell a growth story; the working capital accounts tell a funding crisis - inventory and receivables grew faster than equity could finance, so the gap was bridged by stretching payables and the overdraft. Remedies in priority order: inject equity or long-term debt (match funding to the asset growth); slow the growth; tighten receivables and inventory control. An examiner's one-line diagnosis: profitable on the statement of profit or loss, starving on the statement of financial position.
Company questions may also pull in the investment ratios from the AQA appendix, so keep the set in working memory: earnings per share = profit attributable to ordinary shareholders ÷ number of ordinary shares; dividend per share and dividend yield (dividend ÷ market price × 100 - income as a percentage of what the share costs today); dividend cover = earnings per share ÷ dividend per share (how safely the dividend is paid; cover below about 2 signals strain); and price/earnings = market price ÷ earnings per share (how many years of current earnings the market is paying for - a confidence and growth expectation measure). They belong in answers about shareholders and valuation, and they inherit every limitation listed in section 3 - a window-dressed profit inflates EPS exactly as it inflates the margins.
Seasonality is a final reading caution that shows genuine understanding. A year-end snapshot can misrepresent a seasonal business: a retailer measured in January looks cash-rich and inventory-poor; the same business in November is the reverse. If the question flags a seasonal trade, recommend reading month-end figures through the cycle and comparing like month with like month. And remember the units: days should be sensible (a grocer with 60 inventory days and a car dealer with 60 are telling opposite stories), receivables days beyond credit terms means something is wrong operationally - disputed invoices, a distressed customer, or weak administration - and saying which, with the evidence available, is the analytical standard.
Finally, connect liquidity back to the concepts. Inventory at cost in the current ratio assumes it is worth that - under prudence, write down to net realisable value anything damaged, obsolete or slow-moving before computing the ratio, or your liquidity picture is flattered by stock that will never convert at cost. Receivables in the acid test assume collection - deduct any allowance for doubtful debts, and treat a customer-specific problem as a write-off issue, not just a days ratio. This is the cross-topic reflex AQA likes: an adjustment question in Paper 1 and a ratio question may test the same underlying event from two directions, and students who see both directions answer twice as fast.
Calculation is the cheap half of 3.17. The examinable skill is interpretation and communication: selecting the right ratios for the question, comparing them against the right benchmarks, reading causes behind the numbers, and delivering a conclusion a stakeholder could act on. Build answers on a five-step frame and the 25-mark extended question becomes structured rather than improvised.
Stakeholders need different lenses, and naming the lens shows application. A supplier deciding to sell on credit reads liquidity first (acid test, receivables days, working capital), then gearing. A bank reads interest cover, gearing and cash flow before any margin. A shareholder reads ROCE, the company investment ratios (earnings per share, dividend yield, dividend cover, price/earnings - specified for companies in the AQA appendix), and gearing for risk. Management reads the efficiency set and margins against budget. Two facts matter more than the rest when the question says evaluate for stakeholder X: most accounting data is historical, and stakeholders' decisions are about the future.
Now the limitations - the marks that separate A* from A. Historical cost: statements record what was paid, so inflation distorts margins (revenue is at current prices, depreciation at historic cost, overstating profit in real terms) and non-current asset values may bear no relation to market value. Estimates everywhere: depreciation rates, useful lives, allowance percentages and inventory valuations are judgemental, so two identical businesses can report different profits by policy choice - always check whether the comparative years used consistent policies. Window dressing: legitimate transactions timed to flatter ratios.
Current assets £200,000 (including cash £50,000), current liabilities £150,000: current ratio 1.33:1, acid test 125,000/150,000 = 0.83:1. Two days before the year end, the business pays £20,000 of payables, replenishing the balance after the year end.
The lesson doubles the marks: window dressing works on the ratio it targets but often damages another - and a reader comparing current ratio with acid test spots the manipulation. Combine with a statement that the underlying position is unchanged: the same obligations exist on 2 January.
Single-year, single-company snapshots: one bad year may be investment spending (new stores depress margins now, raise them later); one good year may be luck. Non-financial factors: staff turnover, customer satisfaction, brand, technology and ESG performance shape future cash flows and appear nowhere in the ratios. Data comparability: different year ends, one-off items (restructuring costs, disposal profits), and IFRS-versus-UK terminology all cloud trend reading. The A* evaluation ends with further information required: cash flow statements (profit is an opinion, cash is a fact), segmental data, industry benchmarks, and the notes to the accounts.
Command-word mapping for Paper 1 Section C. Analyse the performance: calculate, compare, explain causes - two linked chains of reasoning minimum. Evaluate the financial position: weigh two-sided evidence (liquidity improved but quality worsened), reach a supported judgement, and state what would change your mind. Discuss the usefulness of ratio analysis: balance the framework's power (comparability, early warning, communication) against the limitations above, and conclude on usefulness for a stated purpose - usefulness is always relative to the decision at hand, which is the sentence examiners underline.
Two additions complete the toolkit. First, the statement of cash flows: profit is built on accruals and estimates, cash is a fact - a company reporting rising profits while cash flow from operations falls is a classic warning combination (profits booked ahead of cash, or working capital absorbing the profit). When a question offers cash flow data, use it as your truth-test in the conclusion. Second, comparability hygiene: check year ends match, watch for one-off items in either year, confirm depreciation policies and allowance rates are consistent across the comparison, and translate any IFRS terminology (revenue/turnover, inventory/stock, receivables/debtors) before computing - mixed terminology is a common source of 'error' in student answers and a gift of an easy fix.
Push the limitations beyond the standard list when the question allows, because the top band rewards developed rather than listed points. Estimates: depreciation rates, useful lives, allowance percentages and inventory valuations are judgemental, so two identical businesses can report different profits by policy choice alone - check whether the comparative years use consistent policies before trusting a trend. Window dressing takes several forms beyond delaying payables: offering unusually generous year-end credit terms to pull sales forward, deferring routine maintenance (cash preserved, expense avoided, risk accumulated), and classifying a short-term loan as long-term to polish liquidity ratios. Non-financial factors - staff turnover, customer satisfaction, brand strength, technology, environmental performance - shape future cash flows and appear nowhere in the ratios; an answer that names one or two relevant to the scenario (a restaurant with high staff turnover, a manufacturer with an ageing machine fleet) turns a generic limitation into applied analysis.
A skeleton for the 25-mark answer, worth committing to memory: paragraph 1 - profitability (two ratios calculated, compared, causes, one limitation); paragraph 2 - liquidity and efficiency (same structure); paragraph 3 - gearing and risk (including interest cover); paragraph 4 - judgement for the named stakeholder with the two strongest pieces of evidence both ways; closing sentence - the further information that would refine the decision. Under exam timing, write the topic sentence of each paragraph first, then fill with figures: if you run out of time, the skeleton alone often secures the structure marks.
One closing discipline: keep your conclusions conditional and evidence-bound. 'The company is illiquid' is a claim; 'on these figures the company's liquidity is weakening - the acid test fell to 0.83:1 and cash covers only a tenth of current liabilities - so, pending sight of the cash flow statement and an aged receivables schedule, credit terms beyond 30 days would be imprudent' is an A* conclusion. The difference is the mechanism (which figure, which direction, what follows) and the stated boundary of the evidence. Ratio analysis never proves anything on its own; your job is to show the reader exactly how far the numbers carry the argument, and where judgement takes over.
