What this dot point is asking

AQA wants you to analyse financial performance using the income statement, calculate gross and net profit and their margins, use financial data to make decisions, and recognise the limitations of financial information.

The income statement

The income statement works top to bottom. It starts with revenue (total sales), subtracts the cost of sales to give gross profit, then subtracts other operating expenses to give net profit (sometimes shown as operating profit at GCSE). Reading down the statement tells you a story: a healthy revenue but a thin net profit points to high overheads, while a falling revenue with a steady margin points to a demand problem rather than a cost problem. AQA case studies usually give you an extract and ask you to pull the right figures and interpret them.

Gross and net profit

Gross profit shows how much is left after the direct cost of goods; net profit shows what is left after all running costs. The two together are diagnostic. If gross profit is strong but net profit is weak, the issue is overheads. If gross profit itself is weak, the issue is either the price charged or the cost of supplies. This is why examiners like questions that move between the two: the point of the analysis is to locate where money is being lost.

Profit margins

A higher margin means the business keeps more of each pound of sales as profit. Margins matter more than the raw profit figure because they let you compare fairly across time and against rivals of different sizes. A corner shop and a supermarket might both make a 20,00020{,}000 net profit, but if the shop did it on 100,000100{,}000 of sales (a 20%20\% margin) and the supermarket on 2,000,0002{,}000{,}000 (a 1%1\% margin), the shop is keeping far more of each pound. Improving a margin means either raising prices, cutting the cost of sales, or trimming overheads, and each route has knock-on effects on demand and quality that an evaluation answer should weigh.

Using and limiting financial data

Financial data helps a business compare performance over time (trend analysis), benchmark against rivals, set targets, support a loan application and make decisions such as whether to cut costs or expand. A bank, an investor and the owner all read the same statement for different reasons. But it has clear limitations that AQA expects you to recognise in higher-mark answers:

Because of these limits, good analysis pairs the numbers with context: a falling margin is only worrying once you know the cause, and a strong year means little if it rests on a one-off. The exam reward is for using the data to reach a supported judgement rather than just quoting it.

Try this

Q1. Revenue is 50,00050{,}000 and cost of sales is 30,00030{,}000. State the gross profit. [1 mark]

  • Cue. 50,00030,000=20,00050{,}000 - 30{,}000 = 20{,}000.

Q2. Net profit is 8,0008{,}000 and revenue is 40,00040{,}000. Calculate the net profit margin. [2 marks]

  • Cue. 8,00040,000×100=20%\dfrac{8{,}000}{40{,}000} \times 100 = 20\%.

AQA 20204 marksA retailer has revenue of 250,000250{,}000, cost of sales of 150,000150{,}000 and other operating expenses of 60,00060{,}000. Calculate the retailer's gross profit margin and net profit margin. (Paper 2, Section B)

Two margins, method rewarded.

Gross profit =250,000150,000=100,000= 250{,}000 - 150{,}000 = 100{,}000. Gross profit margin =100,000250,000×100=40%= \frac{100{,}000}{250{,}000} \times 100 = 40\%.

Net profit =100,00060,000=40,000= 100{,}000 - 60{,}000 = 40{,}000. Net profit margin =40,000250,000×100=16%= \frac{40{,}000}{250{,}000} \times 100 = 16\%.

Full marks need the correct profit figure, division by revenue (not by cost), and the ×100\times 100 to make a percentage. Common errors penalised: dividing net profit by gross profit, or forgetting the ×100\times 100 and giving 0.160.16.

AQA 20239 marksA clothing business has seen its gross profit margin stay at 45%45\% but its net profit margin fall from 12%12\% to 7%7\% over two years. Analyse what this tells the business about its financial performance. (Paper 2, Section C)

A 9-mark analyse question rewarding a chain of reasoning, not definitions.

A steady gross margin means the gap between selling price and the direct cost of sales has not changed, so pricing and supplier costs are stable. Yet the net margin has fallen sharply, which means the problem lies in the other expenses deducted after gross profit: rising rent, wages, marketing or energy bills. The business is selling at the same markup but keeping far less of each pound because overheads have grown.

Develop the consequence: the business should investigate and control its operating expenses (renegotiate rent, review staffing) rather than change its pricing, because pricing is not the cause. Markers reward linking the two margins to locate the problem in overheads, plus a sensible course of action.
