How it works
Ratio analysis turns raw financial statements into comparable measures of performance and position. A profit of 90,000 means little on its own, but a 9% net margin can be compared with competitors, with last year, or with the industry average. The calculator groups 16 standard ratios into the four families that ACCA FR, ICAP CAF, ICAEW Accounting and US CMA Part 2 examiners test.
Liquidity: can the business pay its short-term debts?
Current ratio = Current assets ÷ Current liabilities
Quick ratio = (Current assets − Inventory) ÷ Current liabilitiesProfitability: how well does it turn sales and capital into profit?
Gross margin = Gross profit ÷ Revenue
Operating margin = PBIT ÷ Revenue
ROCE = PBIT ÷ (Equity + Non-current debt)
ROE = Profit after tax ÷ EquityROCE breaks down into operating margin × asset turnover, which shows whether a change in return comes from pricing and costs or from how hard the assets are worked.
Efficiency: how quickly does working capital turn over?
Inventory days = Inventory ÷ Cost of sales × 365
Receivable days = Trade receivables ÷ Revenue × 365
Payable days = Trade payables ÷ Cost of sales × 365Gearing: how much financial risk is there?
Gearing = Debt ÷ (Debt + Equity)
Interest cover = PBIT ÷ Interest expenseWorked example
The example figures loaded in the calculator describe a company with revenue of 1,000,000:
- Current ratio 250,000 ÷ 125,000 = 2.0x, and quick ratio (250,000 − 120,000) ÷ 125,000 = 1.04x. Liquidity is healthy even without selling inventory.
- Gross margin 400,000 ÷ 1,000,000 = 40%, and operating margin 15%.
- ROCE 150,000 ÷ (500,000 + 250,000) = 20%. That equals the 15% operating margin × 1.33 turnover of capital employed.
- Inventory days 120,000 ÷ 600,000 × 365 = 73 days, and receivable days 100,000 ÷ 1,000,000 × 365 = 36.5 days.
- Gearing 250,000 ÷ 750,000 = 33.3%, and interest cover 150,000 ÷ 30,000 = 5x. That is moderate debt, comfortably serviced.
Change any input and every ratio and interpretation updates instantly. Try halving operating profit to see interest cover fall into the danger zone.
Limitations to mention
Ratios rely on historical figures, can be distorted by year-end window dressing, seasonal trade or different accounting policies (such as revaluations or depreciation methods), and need a meaningful comparator. In exam answers, pair each calculation with a reason drawn from the scenario.
