What this dot point is asking

AQA wants you to calculate and interpret profitability, liquidity and efficiency ratios, compare them over time and between businesses, and explain the limitations of ratio analysis. This is unit 3.1.12, and it carries the highest-tariff extended-answer questions on Paper 1, where marks are weighted towards interpretation and judgement (AO3) rather than the arithmetic.

Profitability ratios

Gross profit margin reflects the trading core: pricing, purchasing and sales mix. Profit for the year margin captures the effect of operating overheads and finance costs on top, so comparing the two margins over time is highly informative: a rising gross margin with a falling profit margin signals that overheads, not trading, are the problem. ROCE is the headline return measure, comparable to the interest a lender would charge or an investor could earn elsewhere; capital employed is total equity plus non-current liabilities (the long-term funding of the business).

Liquidity and efficiency ratios

Definition

The current ratio is $\dfrac{\text{current assets}}{\text{current liabilities}}$ , and the acid test (quick ratio) is $\dfrac{\text{current assets} - \text{inventory}}{\text{current liabilities}}$ , both measuring the ability to meet short-term debts; the acid test excludes inventory as the least liquid current asset. Efficiency ratios include the trade receivables collection period $\left(\dfrac{\text{trade receivables}}{\text{credit sales}} \times 365\right)$ , the trade payables payment period $\left(\dfrac{\text{trade payables}}{\text{credit purchases}} \times 365\right)$ , and inventory turnover $\left(\dfrac{\text{cost of sales}}{\text{average inventory}}\right)$ .

Liquidity ratios must be read with industry context: a supermarket with fast inventory turnover and few receivables can survive on a current ratio well below the textbook 1.5 to 2.0, while a manufacturer holding slow inventory needs more cover. The efficiency ratios link directly to working capital management: a lengthening receivables period ties up cash, a lengthening inventory period risks obsolescence, and stretching the payables period (within agreed terms) preserves cash.

Worked interpretation

Calculating and judging together

Gross profit margin

A business has revenue $200{,}000$ , gross profit $80{,}000$ , operating profit $30{,}000$ and capital employed $150{,}000$ . Gross profit margin $= \dfrac{80{,}000}{200{,}000} \times 100 = 40\%$ .

Return on capital employed

$\text{ROCE} = \dfrac{30{,}000}{150{,}000} \times 100 = 20\%$ .

Compare and interpret

A $20\%$ ROCE comfortably exceeds typical borrowing rates, so the capital is working hard. But the figures are only meaningful against last year, a competitor or an industry benchmark; a $40\%$ gross margin that has fallen from $45\%$ would signal price discounting or rising input costs.

State a judgement

The strong answer ends with a conclusion: on these figures the business is profitable and the capital is well used, but the trend and the benchmark must be checked before recommending action.

Limitations

Ratios use historic figures, so they describe the past not the future. They ignore qualitative factors such as staff capability, brand strength, customer loyalty and market conditions. They can be distorted by different accounting policies (depreciation method, inventory valuation), making cross-company comparison unreliable. A single ratio is meaningless without comparison, and period-end figures can be window-dressed. Always interpret and compare; never merely calculate.

Try this

Q1. A business has current assets $60{,}000$ , inventory $20{,}000$ and current liabilities $30{,}000$ . Calculate the acid test ratio. [2 marks] $\dfrac{60{,}000 - 20{,}000}{30{,}000} = 1.33$ .

Q2. State two limitations of ratio analysis. [2 marks] For example it uses historic data and ignores qualitative factors.

Exam-style practice questions

Practice questions written in the style of AQA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

AQA 20188 marksA business reports revenue

400,000, gross profit

160,000, operating profit

60,000, capital employed

300,000, current assets

90,000 (including inventory

30,000) and current liabilities $50,000. Calculate the gross profit margin, return on capital employed, current ratio and acid test ratio, and comment on the liquidity position.

A full worked ratio question; each ratio earns method and answer marks.

Gross profit margin: gross profit over revenue times 100 = (160,000 / 400,000) times 100 = 40% (2 marks).

Return on capital employed: operating profit over capital employed times 100 = (60,000 / 300,000) times 100 = 20% (2 marks).

Current ratio: current assets over current liabilities = 90,000 / 50,000 = 1.8 to 1 (2 marks).

Acid test: (current assets minus inventory) over current liabilities = (90,000 - 30,000) / 50,000 = 1.2 to 1 (1 mark).

Comment: both liquidity ratios are above 1, and the acid test of 1.2 shows the business can cover short-term debts even without selling inventory, a healthy position (1 mark). Markers reward correct formulae, the times-100 on percentages, and a comment tied to the figures.

AQA 20215 marksA company's gross profit margin has risen but its profit for the year margin has fallen over two years. Analyse the possible reasons and what this suggests about the business.

Show worked answer →

A 5-mark "Analyse" answer must reason from the divergence, not just define the ratios.

Gross margin rising means the business is keeping more of each sales pound after cost of sales, perhaps from higher selling prices, cheaper suppliers or a better sales mix (1 to 2 marks).

Profit margin falling despite this means operating expenses have risen faster than the gross gain, for example higher wages, marketing, rent or finance costs, or a one-off expense (2 marks).

The implication: the trading performance has improved but cost control below gross profit has worsened, so management should investigate overheads; the divergence is more informative than either ratio alone (1 mark). Markers reward analysing the gap between the two margins, not restating definitions.
