10.1 Financial Statements – Statement of Profit or Loss (Income Statement)
1. Objective
To understand the meaning, statutory basis, purpose and structure of the Statement of Profit or Loss (SPL), how it links to the Statement of Financial Position, and how it is used by internal and external users of financial information.
2. What is the Statement of Profit or Loss?
- Definition: A financial statement that records a company’s revenue, expenses and the resulting profit or loss for a defined period (usually a year or a quarter).
- Statutory requirement: Mandatory under UK GAAP (FRS 102) and IFRS (IAS 1) as part of a complete set of financial statements.
Net Profit (Loss) = Total Revenue – Total Expenses
3. Primary Purposes
- Assess the profitability of the business during the reporting period.
- Provide information for managerial planning, control and strategic decision‑making.
- Supply external users (investors, lenders, suppliers, tax authorities, employees) with evidence of the firm’s ability to generate earnings and meet obligations.
- Form the basis for calculating retained earnings that appear in the Statement of Financial Position.
- Explain the movement in equity from one balance‑sheet date to the next (see Section 11).
4. Key Components – Definitions & Typical Items
- Revenue (Sales) – Total inflow from the entity’s core activities before any deductions.
- Typical items: cash sales, credit sales, service fees, interest income (if part of core business).
- Cost of Sales (Cost of Goods Sold – COGS) – Direct costs attributable to the production of goods sold or services delivered.
- Typical items: raw materials, direct labour, production overheads (e.g., factory utilities).
- Gross Profit – Revenue less Cost of Sales.
- Operating Expenses – Costs of running the business that are not directly tied to production.
- Salaries & wages (administrative), rent, utilities, advertising, depreciation, amortisation, research & development, insurance.
- Operating Profit (EBIT) – Earnings before interest and tax; Gross Profit less Operating Expenses.
- Interest Expense – Cost of borrowing (interest on loans, bonds, overdrafts).
- Profit Before Tax (PBT) – Operating Profit less Interest Expense (and any other non‑operating items such as gains/losses on disposals).
- Tax Expense – Current corporation tax payable on profit before tax.
- Net Profit (or Net Loss) – Final profit after all expenses, interest and tax have been deducted.
5. Inventory Valuation – Net Realisable Value (NRV)
For the SPL, inventory must be valued at the lower of cost and Net Realisable Value (NRV). NRV is the estimated selling price less estimated costs of completion and disposal.
| Item | Cost (£) | Estimated Selling Price (£) | Estimated Disposal Costs (£) | NRV (£) | Value Used (£) |
|---|
| Finished goods A | 12,000 | 15,000 | 1,500 | 13,500 | 12,000 (cost lower) |
| Finished goods B | 8,000 | 9,000 | 300 | 8,700 | 8,700 (NRV lower) |
Only the lower amount is recorded in Cost of Sales.
6. Depreciation – Straight‑Line Method (required for the exam)
Only the straight‑line method is examined in Cambridge 9609.
Formula:
Depreciation expense per year = (Cost of asset – Residual value) ÷ Useful life (years)
Example: A machine costs £30,000, has a residual value of £5,000 and a useful life of 5 years.
- Depreciation = (£30,000 – £5,000) ÷ 5 = £5,000 per year.
- The £5,000 is recorded as an operating expense in the SPL.
7. Cost Classifications & Costing Methods
| Classification | Definition | Examples |
|---|
| Direct costs | Costs that can be traced directly to a product or service. | Raw material, direct labour. |
| Indirect costs | Costs that cannot be traced directly; allocated to products. | Factory overhead, administration. |
| Fixed costs | Do not vary with output. | Rent, salaries of permanent staff. |
| Variable costs | Vary directly with output. | Raw material, direct labour (hourly). |
Full (Absorption) Costing: All production costs (direct + indirect + fixed) are absorbed into the cost of each unit. Used for external reporting.
Contribution (Marginal) Costing: Only variable production costs are assigned to units; fixed production costs are treated as period expenses. Useful for internal decision‑making (break‑even analysis, pricing).

Cost of Sales 300,000
Gross Profit 200,000

Change in depreciation method increased depreciation by £5,000 and re‑classified £15,000 of overheads from COGS to operating expenses. |

11. Link to the Statement of Financial Position (Balance Sheet)
- Net profit for the period is added to Retained Earnings (or deducted if a loss) in the equity section of the Statement of Financial Position.
- Dividends declared (but not yet paid) are subtracted from retained earnings after the SPL is prepared.
- Thus, the SPL explains the movement in equity from one balance‑sheet date to the next.
12. Limitations of the Statement of Profit or Loss
- Prepared on an accrual basis – does not show actual cash inflows/outflows.
- Historical cost accounting may undervalue assets and distort profit (e.g., revaluation gains are excluded).
- Non‑operating items (one‑off gains/losses, tax adjustments) can obscure core operating performance.
- Subject to management’s accounting estimates (depreciation, provisions) which involve judgment.
- Only covers a single period; trend analysis is required for a fuller picture.
13. Ratios Derived from the Statement of Profit or Loss
These ratios are examined in Cambridge 9609 and help interpret raw figures.
| Ratio | Formula | Interpretation |
|---|
| Gross Profit Margin |
(Gross Profit ÷ Revenue) × 100 % |
Measures efficiency of production/purchasing. |
| Operating Profit Margin |
(Operating Profit ÷ Revenue) × 100 % |
Shows profitability after covering operating costs. |
| Net Profit Margin |
(Net Profit ÷ Revenue) × 100 % |
Overall profitability after all expenses. |
| Earnings per Share (EPS) |
(Net Profit – Preferred Dividends) ÷ Shares Outstanding |
Profit attributable to each ordinary share. |
| Current Ratio (Liquidity) |
Current Assets ÷ Current Liabilities |
Ability to meet short‑term obligations. |
| Acid‑Test (Quick) Ratio |
(Current Assets – Inventories) ÷ Current Liabilities |
Liquidity excluding inventory. |
| Return on Capital Employed (ROCE) |
Operating Profit ÷ (Total Assets – Current Liabilities) × 100 % |
Efficiency of capital utilisation. |

14. Cash‑Flow Forecasts (Link to the SPL)
Although cash‑flow statements are a separate financial statement, the SPL provides the basis for forecasting cash inflows and outflows.
| Cash‑flow Category | Typical Sources / Uses |
|---|
| Operating cash‑inflows | Cash sales, collection of credit sales, interest received (if operating). |
| Operating cash‑outflows | Payments to suppliers (COGS), wages, rent, tax payments, interest paid. |
| Investing cash‑flows | Purchase or sale of plant & equipment (linked to depreciation), investment in securities. |
| Financing cash‑flows | Proceeds from loans or issue of shares, dividend payments, repayment of borrowings. |
Simple cash‑flow forecast example (quarterly):
| Quarter | Cash In (£) | Cash Out (£) | Net Cash Flow (£) |
|---|
| Q1 | 120,000 | 95,000 | 25,000 |
| Q2 | 130,000 | 100,000 | 30,000 |
| Q3 | 115,000 | 90,000 | 25,000 |
| Q4 | 140,000 | 110,000 | 30,000 |
Operating cash‑flows are derived from the SPL figures (e.g., sales, COGS, operating expenses, tax and interest).
15. Preparing the Statement – Step‑by‑Step Checklist
- Collect all revenue figures for the period (sales invoices, service contracts, etc.).
- Value opening inventory and calculate closing inventory at the lower of cost and NRV; determine Cost of Sales.
- Derive Gross Profit (Revenue – Cost of Sales).
- Identify and total all Operating Expenses, including straight‑line depreciation.
- Compute Operating Profit (EBIT) = Gross Profit – Operating Expenses.
- Adjust for non‑operating items (gains/losses, interest expense) to obtain Profit Before Tax.
- Apply the appropriate corporate tax rate to calculate Tax Expense.
- Subtract Tax Expense to arrive at Net Profit (or Net Loss).
- Link Net Profit to Retained Earnings in the Statement of Financial Position and record any dividends declared.
- Review the SPL for compliance with FRS 102/IAS 1 presentation requirements and for any required disclosures.
16. Summary
The Statement of Profit or Loss is a compulsory financial statement that records a company’s ability to generate profit over a defined period. It details revenue, cost of sales, operating expenses, interest, tax and the resulting profit. Mastery of its structure, the required inventory valuation (NRV), straight‑line depreciation, cost classifications, and the link to the balance sheet is essential for Cambridge A‑Level Business (9609). In addition, students must be able to calculate and interpret a full set of profitability, liquidity, efficiency and gearing ratios, and understand how the SPL feeds into cash‑flow forecasts.
