Profit and the Income Statement (Edexcel 9BS0 2.3.1)
This topic covers the three measurements of profit, how they appear in the income statement (Edexcel's statement of trading performance), the margin ratios built from them, and the difference between profit and cash. Calculation questions here are near-guaranteed marks if you know the structure of the statement cold.
The structure of the statement
The income statement records a business’s trading performance over a period, usually a year, line by line from revenue down to the profit kept. Learn the order — Edexcel questions often give you two lines and ask for a third:
- Revenue (sales value, not cash received)
- minus cost of sales = gross profit
- minus operating expenses (rent, marketing, administration) = operating profit
- minus interest and other finance costs = net profit before tax
Each level answers a different question. Gross profit tests whether the core buying-and-selling activity works. Operating profit adds the cost of running the organisation around it. Net profit shows what is left for tax, dividends and reinvestment after the cost of borrowing — a figure that mattered more while interest rates stayed high through 2024 and 2025. Greggs reported revenue of £2,014m and pre-tax profit of £203.9m for 2024, numbers that only make sense once you can trace this structure.
Profit margins: the calculations
Margins turn profit into a percentage of revenue so that different-sized firms, or different years, can be compared fairly.
Worked example: a firm has revenue of £500,000, cost of sales of £320,000 and net profit of £45,000.
- Gross profit = 500,000 − 320,000 = £180,000
- Gross profit margin = 180,000 ÷ 500,000 × 100 = 36%
- Net profit margin = 45,000 ÷ 500,000 × 100 = 9%
The gap between the two margins is where overheads and interest live — here 27p of every £1 of sales. Real benchmarks help interpretation: Greggs’ 2024 pre-tax margin was around 10%, typical for food-on-the-go, while Next’s profit passed £1bn in the year to January 2025 on sales of just over £6bn, a margin around 16% that reflects premium pricing and a profitable online platform. A ‘good’ margin always depends on the industry.
Improving profit, and why profit is not cash
There are only two routes to higher profit: raise revenue or cut costs, and each carries a trade-off worth analysing. Raising prices widens margins but risks volume if demand is price-elastic; cutting ingredient quality lowers cost of sales but can destroy the reputation that supports the price. The best answers link the method to the specific business in the case.
The specification also demands the distinction between profit and cash, and it decides real survival:
- Revenue is recorded when a sale is made, but a customer on 60-day credit terms has paid nothing yet.
- A profitable firm can therefore run out of cash while waiting for receivables, especially when growing fast.
- Cash-rich months can hide an unprofitable model, as when deposits arrive before costs.
Examiners phrase it simply: profit is a matter of record, cash is a matter of timing. Confusing the two in an essay caps the answer.
Key terms
Practice questions
A business has revenue of £500,000, cost of sales of £320,000 and net profit of £45,000. Calculate the gross profit margin and the net profit margin. [4 marks]
Model answer guidance: Gross profit = £500,000 − £320,000 = £180,000. Gross profit margin = 180,000 ÷ 500,000 × 100 = 36%. Net profit margin = 45,000 ÷ 500,000 × 100 = 9%. Show the formula, the substitution and the percentage sign for full marks.
Explain one reason why a business can make a profit yet still run out of cash. [4 marks]
Model answer guidance: Identify the timing gap: revenue is recorded at the point of sale, not payment. Develop the chain — a firm selling on 60-day credit records profit immediately but waits two months for cash, while wages and suppliers must be paid now, so a growing order book can drain the bank account even as reported profit rises.
Discuss whether cutting costs is the best way for a food-on-the-go retailer to improve its net profit margin. [8 marks]
Model answer guidance: For: ingredient, energy and wastage savings flow straight to profit without needing extra customers, valuable when wage costs are rising. Against: visible quality cuts risk the value-for-money reputation the model depends on, and margins can also be improved by raising average transaction value through meal deals. Conclude that cost control works best when invisible to customers, so the source of the saving is the deciding factor.
Assess the usefulness of comparing profit margins between two businesses in different industries. [10 marks]
Model answer guidance: Useful: margins standardise for size, reveal different business models and help investors judge where each pound of sales goes. Limited: a supermarket running on 3% and a software firm on 25% may both be performing well for their sector, cost structures differ, and one-off items distort single years. Judgement: comparisons are meaningful against the same firm's history or sector average, weak across unrelated industries.
Assess whether a rising gross profit margin combined with a falling net profit margin should worry the shareholders of a retailer. [12 marks]
Model answer guidance: The pattern means trading is healthy but overheads or interest are swallowing the gains — possible causes include rising rents, marketing spend or debt costs at higher interest rates. Worrying if overhead growth is structural; less so if it reflects deliberate investment in stores or systems that will lift future profit. A strong judgement asks whether the spending is chosen or suffered, and over what timescale it should pay back.
Examiner tips
- Memorise the statement's order — revenue, cost of sales, gross profit, operating expenses, operating profit, interest, net profit — because Edexcel loves giving two lines and asking for a third.
- Always interpret a margin against a benchmark: the same firm last year or a named rival, never against a vague idea of 'high' or 'low'.
- Use the phrase 'profit is recorded, cash is received' to anchor any answer on the profit–cash distinction.
