3.5.3 - Financial performance and decisions
Learn how financial documents and ratios inform performance judgements and business decisions, including calculating average rate of return for an investment.
Reading financial performance
Financial performance is clearer when income, financial position and cash evidence are considered together.
An income statement shows revenue, expenses and profit over a period. A statement of financial position shows assets, liabilities and equity at a date. A cash-flow forecast estimates the timing of cash receipts and payments. These documents answer different questions: whether trading generates profit, what resources and obligations exist, and whether cash should be available when needed. Reading them does not require constructing the statements.
The following annual data are illustrative for a manufacturer with consistent accounting policies. All amounts are USD thousands for years ending 31 December. Profit for the year is after finance costs and tax.
| Measure | 2024 | 2025 |
|---|---|---|
| Revenue | 500 | 600 |
| Cost of sales | 300 | 360 |
| Gross profit | 200 | 240 |
| Other operating expenses | 150 | 198 |
| Operating profit | 50 | 42 |
| Profit for the year | 35 | 24 |
| Capital employed, stated year-end basis | 250 | 300 |
| Gross profit margin | 40% | 40% |
| Operating profit margin | 10% | 7% |
| Net profit margin | 7% | 4% |
| ROCE | 20% | 14% |
Gross margin in 2025 is ; net margin is . Although revenue and gross profit increased, other operating expenses grew enough to reduce operating profit and margin. The operating margin fell by 3 percentage points, from 10% to 7%; that is a 30% relative decrease in the margin, not a 3% relative decrease. ROCE also fell because operating profit fell while capital employed increased.

Illustrative annual margins, using the table above: revenue growth did not prevent lower operating and net profitability.
The owner should investigate the extra operating expenses, rather than assuming weak sales caused the falling margin. New equipment and training might support future growth but raise costs now. Net margin may also change because of finance costs or tax. The statement of financial position and cash forecast can show whether expansion increased debt or creates a payment shortage despite profitable sales.
Using documents for decisions
Financial evidence helps decision makers choose actions by showing their likely constraints and consequences.
Managers can compare costs and margins to identify where performance needs attention. If operating expenses have risen while gross margin is steady, investigating overtime or administration is more directly supported than changing suppliers automatically. Before expansion, the cash forecast can reveal whether equipment payments fall due before extra sales receipts arrive. The statement of financial position can show existing borrowing and resources; profitable trading alone does not establish that another loan is affordable.
Lenders may use liquidity, debt and profit evidence when judging repayment risk. Investors may consider profit for the year and returns relative to capital, together with risk and future prospects. Suppliers deciding whether to offer credit may focus on payment ability. The useful document depends on the decision: last year's income statement cannot by itself predict next month's bank balance.
In an illustrative manufacturer, a new line could cut annual production costs, but equipment must be paid for immediately and customers receive two months' credit. The income effect may be favourable while the cash forecast reveals a temporary shortage. A manager could investigate staged payments or suitable finance before deciding. Each option has costs and conditions: borrowing incurs interest, and staged payments require the supplier's agreement. Link evidence to the consequence and judge whether it meets the business's objective; figures do not make the decision automatically.
