3.4.1 - Statements of comprehensive income
Read the main features of a statement of comprehensive income and use them to judge business performance. Explain why profit matters and why a profitable business still needs enough cash to pay its bills.
Reading income statement features
A statement of comprehensive income shows a business's revenue, costs and profit for a stated accounting period.
The period could be a month or a year; it is not a snapshot of assets and debts on one date. Managers use the statement to identify where profit is earned or reduced. Owners and potential lenders can use it to judge performance, alongside other financial information. This course requires you to interpret a supplied statement, not construct one.
The specification uses sales when listing features; assessments use the International Accounting Standards term revenue. Familiar older labels such as profit and loss account can help you recognise the document, but use its supplied IAS labels when interpreting figures.
| Feature | Meaning |
|---|---|
| Revenue | Income earned from sales during the period, before costs are deducted. |
| Cost of sales | The cost of the goods or services sold in the period, rather than every business expense. For a retailer, this includes the purchase cost of the goods actually sold. |
| Gross profit | Revenue less cost of sales. It shows what remains to cover other operating expenses. |
| Other operating expenses | Costs of running the business not already included in cost of sales, such as administration, rent or marketing in the supplied statement. |
| Operating profit | Gross profit less other operating expenses: profit from operating activity before items such as finance costs and tax. |
These are supplied in specification Appendix 4. Use the classifications in the given statement and avoid deducting the same cost twice.
Illustrative statement extract for a retailer, year ended 31 December 2025, all amounts in dollars:
| Item | Amount ($) |
|---|---|
| Revenue | 180,000 |
| Cost of sales | 108,000 |
| Gross profit | 72,000 |
| Other operating expenses | 52,000 |
| Operating profit | 20,000 |
Gross profit is . Deducting $52,000 expenses leaves $20,000 operating profit. Calling the whole $72,000 the amount available to owners would overlook those expenses. Inventory not yet sold is different from cost of sales for goods sold in this period.
Profit for the year is not automatically the same as operating profit. If finance costs of $3,000 and tax of $4,000 are the only further items in an illustrative extract, profit for the year is . This is the IAS term for what older sources may call net profit. Do not substitute it for operating profit when the task asks for operating profit.
Income data in decisions
Comparing the components of profit helps managers identify which changes deserve investigation before making a decision.
Illustrative annual extracts for the same retailer use identical classifications, currency and twelve-month periods:
| Item ($) | 2024 | 2025 |
|---|---|---|
| Revenue | 150,000 | 180,000 |
| Cost of sales | 90,000 | 108,000 |
| Gross profit | 60,000 | 72,000 |
| Other operating expenses | 38,000 | 52,000 |
| Operating profit | 22,000 | 20,000 |
Revenue grows by $30,000, or 20%, and gross profit grows by $12,000. Yet operating profit falls by $2,000 because expenses rise by $14,000. Looking only at higher sales would miss this deterioration. Managers might investigate extra marketing or premises costs, renegotiate suitable contracts, or check whether the increased expenses are a temporary cost of expansion.
For a retailer, higher cost of sales could lead it to compare suppliers or review prices. Cutting supplier costs may improve gross profit, but inferior goods could reduce customer demand. Raising prices may increase revenue per item, but customers might buy fewer items. The statement identifies a financial issue; product quality, competition and customers help decide the response.
