What you'll learn
This topic teaches you how to evaluate business performance by calculating and interpreting key financial ratios from statements of financial position and income statements. CIE IGCSE Accounting exams regularly test your ability to compute ratios, compare results across periods, and provide reasoned commentary on a business's profitability, liquidity and efficiency.
Key terms and definitions
Ratio analysis — the process of calculating numerical relationships between figures in financial statements to assess business performance and position.
Profitability ratios — measures that show how effectively a business generates profit relative to sales, capital employed or equity investment.
Liquidity ratios — indicators of a business's ability to meet short-term debts and obligations as they fall due.
Return on Capital Employed (ROCE) — profit expressed as a percentage of the capital invested in the business; measures efficiency of capital usage.
Gross profit margin — gross profit as a percentage of revenue (sales); shows profit before expenses.
Net profit margin — profit for the year as a percentage of revenue; shows profit after all expenses.
Current ratio — current assets divided by current liabilities; measures short-term liquidity.
Liquid (acid test) ratio — (current assets minus inventory) divided by current liabilities; stricter liquidity measure excluding inventory.
Core concepts
Understanding ratio categories
Financial ratios fall into three main categories tested at IGCSE level:
Profitability ratios measure how successfully a business generates profit:
- Gross profit margin: (Gross profit ÷ Revenue) × 100
- Net profit margin: (Profit for the year ÷ Revenue) × 100
- Return on Capital Employed: (Profit for the year ÷ Capital employed) × 100
Liquidity ratios assess the ability to pay short-term debts:
- Current ratio: Current assets ÷ Current liabilities
- Liquid (acid test) ratio: (Current assets – Inventory) ÷ Current liabilities
Efficiency ratios evaluate how well resources are managed:
- Rate of inventory turnover: Cost of sales ÷ Average inventory
- Return on equity (ROE): (Profit for the year ÷ Equity) × 100
Calculating profitability ratios
Gross profit margin indicates the profit made on trading activities before expenses are deducted. A business with revenue of $80,000 and gross profit of $32,000 has a gross profit margin of 40% [(32,000 ÷ 80,000) × 100]. Higher percentages suggest better control over purchasing costs or stronger pricing power. Retail businesses typically have lower margins (20-40%) than service businesses (50-80%).
Net profit margin shows the percentage of revenue remaining after all expenses. If the same business has a profit for the year of $8,000, the net profit margin is 10% [(8,000 ÷ 80,000) × 100]. This ratio reveals how efficiently expenses are controlled. A declining net profit margin despite stable gross profit margin indicates rising operating expenses.
Return on Capital Employed (ROCE) measures profit relative to the total resources invested. Capital employed equals non-current liabilities plus equity, or total assets minus current liabilities. If capital employed is $50,000 and profit for the year is $8,000, ROCE is 16% [(8,000 ÷ 50,000) × 100]. This ratio allows comparison with alternative investments and competitor performance. ROCE above 15% generally indicates good capital utilization in most sectors.
Calculating liquidity ratios
Current ratio compares current assets to current liabilities. A business with current assets of $25,000 and current liabilities of $10,000 has a current ratio of 2.5:1 (25,000 ÷ 10,000). This means the business has $2.50 of current assets for every $1.00 of current liabilities. The ideal current ratio typically ranges between 1.5:1 and 2:1. Ratios below 1:1 indicate potential liquidity problems; ratios above 3:1 may suggest inefficient use of resources.
Liquid (acid test) ratio provides a stricter test by excluding inventory, which cannot be converted to cash immediately. If the business above holds inventory of $8,000, the liquid ratio is 1.7:1 [(25,000 – 8,000) ÷ 10,000]. A minimum of 1:1 is considered acceptable, though 0.8:1 to 1:1 can be sufficient for businesses with rapid cash inflows like supermarkets. Manufacturing businesses typically need higher liquid ratios than retailers.
Interpreting ratio results
Ratios become meaningful through comparison:
Trend analysis — comparing the same business's ratios over multiple accounting periods identifies improvement or deterioration. A gross profit margin declining from 42% to 38% to 35% over three years signals problems with pricing or supplier costs.
Inter-firm comparison — comparing ratios with competitors or industry averages reveals relative performance. A ROCE of 12% appears weak if the industry average is 18% but strong if the average is 8%.
Context is essential:
- A low current ratio (0.9:1) may be acceptable for a cash business like a supermarket with rapid inventory turnover
- High profitability ratios with low liquidity ratios suggest overtrading
- Seasonal businesses show ratio fluctuations depending on the statement date
- Economic conditions affect acceptable ratio levels
Calculating rate of inventory turnover
Rate of inventory turnover measures how many times per year a business sells and replaces its inventory. The formula is: Cost of sales ÷ Average inventory. If cost of sales is $48,000 and average inventory (opening plus closing divided by 2) is $6,000, inventory turns over 8 times per year.
Higher turnover indicates:
- Efficient inventory management
- Fresh stock (important for perishable goods)
- Lower storage costs
Lower turnover suggests:
- Slow-moving or obsolete stock
- Overstocking
- Poor buying decisions
Inventory turnover varies by sector: supermarkets (20-30 times), furniture retailers (4-6 times), jewelers (1-2 times).
Making recommendations from ratios
Exam questions frequently require recommendations based on ratio analysis. Strong answers:
- Identify the problem clearly using ratio evidence
- Explain the cause — what financial decision created this result
- Suggest specific actions with reasoning
For declining profitability:
- Increase selling prices (if market allows)
- Negotiate better supplier terms to reduce cost of sales
- Cut operating expenses through efficiency savings
- Discontinue unprofitable product lines
For poor liquidity:
- Negotiate extended payment terms with suppliers
- Offer discounts for prompt payment by receivables
- Reduce inventory levels
- Inject additional capital
- Arrange bank overdraft facilities
Limitations of ratio analysis
Examiners expect awareness that ratios have limitations:
- Historical data — ratios use past figures; conditions may have changed
- Accounting policies — different depreciation methods or inventory valuations affect comparability between businesses
- External factors — ratios don't capture market conditions, management quality or competitive threats
- Manipulation — window dressing can artificially improve ratios
- Qualitative factors — staff morale, customer loyalty and brand reputation don't appear in ratios
- Inflation — comparisons over time may be distorted by price changes
Worked examples
Example 1: Profitability analysis
The income statements for Hassan Trading show:
| 2023 | 2024 | |
|---|---|---|
| Revenue | $150,000 | $180,000 |
| Cost of sales | $90,000 | $117,000 |
| Gross profit | $60,000 | $63,000 |
| Expenses | $35,000 | $42,000 |
| Profit for the year | $25,000 | $21,000 |
Required: Calculate gross profit margin and net profit margin for both years and comment on the results. [6 marks]
Solution:
Gross profit margin 2023: (60,000 ÷ 150,000) × 100 = 40%
Gross profit margin 2024: (63,000 ÷ 180,000) × 100 = 35%
Net profit margin 2023: (25,000 ÷ 150,000) × 100 = 16.7%
Net profit margin 2024: (21,000 ÷ 180,000) × 100 = 11.7%
Commentary:
Both profitability ratios have declined significantly. The gross profit margin fell by 5 percentage points, indicating Hassan paid more for purchases relative to sales revenue or reduced selling prices to increase volume. The net profit margin fell by 5 percentage points, showing expenses increased disproportionately to revenue (20% expense growth versus 20% revenue growth but from lower profit base). Despite higher revenue, actual profit decreased by $4,000. Hassan should review supplier contracts, increase prices if possible, and control expenses more tightly.
Example 2: Liquidity analysis
Zara's statement of financial position extracts:
| 31 March 2024 | |
|---|---|
| Current assets: | |
| Inventory | $18,000 |
| Trade receivables | $12,000 |
| Bank | $3,000 |
| $33,000 | |
| Current liabilities: | |
| Trade payables | $15,000 |
| Bank overdraft | $3,000 |
| $18,000 |
Required: Calculate the current ratio and liquid ratio. State whether the liquidity position is satisfactory. [5 marks]
Solution:
Current ratio: 33,000 ÷ 18,000 = 1.83:1
Liquid ratio: (33,000 – 18,000) ÷ 18,000 = 0.83:1
Assessment:
The current ratio of 1.83:1 is within the ideal range (1.5:1 to 2:1), suggesting satisfactory short-term liquidity. However, the liquid ratio of 0.83:1 is slightly below the recommended minimum of 1:1. This indicates Zara may face difficulties meeting immediate debts if inventory cannot be sold quickly. The business should consider reducing inventory levels, collecting receivables more promptly, or negotiating extended payment terms with suppliers to improve the liquid position.
Example 3: Return on Capital Employed
Ahmed's business shows capital employed of $80,000 on 31 December 2024 and profit for the year of $14,400. A competitor's ROCE is 20%.
Required: Calculate Ahmed's ROCE and compare it with the competitor. [4 marks]
Solution:
ROCE: (14,400 ÷ 80,000) × 100 = 18%
Ahmed's ROCE of 18% indicates that for every $100 invested in the business, $18 profit is generated annually. This represents reasonable capital efficiency. However, the competitor's ROCE of 20% is superior, meaning the competitor generates $2 more profit per $100 invested. Ahmed should investigate whether the competitor achieves higher profit margins or uses capital more efficiently. Ahmed might improve ROCE by increasing profit (through higher prices or lower costs) or reducing capital employed (by paying off loans or withdrawing excess capital).
Common mistakes and how to avoid them
Confusing gross and net profit in margin calculations — gross profit margin uses gross profit (before expenses); net profit margin uses profit for the year (after all expenses). Check which profit figure the question specifies.
Forgetting to multiply by 100 for percentage ratios — profitability ratios and ROCE must be expressed as percentages. A gross profit margin of 0.35 is incorrect; write 35%.
Calculating ratios as percentages when they should be ratios — current ratio and liquid ratio are expressed as X:1 format, not percentages. Write 2.5:1, not 250%.
Omitting inventory from current assets when calculating liquid ratio — the liquid ratio must deduct inventory from current assets. Using the full current assets figure produces the current ratio, not the liquid ratio.
Failing to interpret or comment after calculating ratios — calculation alone earns limited marks. Examiners award most marks for explaining what the ratio means, whether it's satisfactory, and suggesting improvements.
Comparing ratios between businesses without acknowledging different contexts — recognize that acceptable ratio levels vary by industry, business model and economic conditions. A supermarket naturally has different liquidity ratios than a manufacturing business.
Exam technique for Analysis and Interpretation of Financial Statements
Command word "Calculate" requires numerical answers with workings shown. Present formulae, substitute figures, show calculations and state answers clearly with appropriate units (%, :1). Marks are awarded for method even if the final answer is wrong.
Command word "Comment" or "State whether satisfactory" requires interpretation. Define what the ratio measures, state whether the figure is acceptable (with reference to ideal ranges or benchmarks), and explain what caused the result or what problems it indicates. Typically 2-3 marks available per ratio commented upon.
Marks for recommendations are earned by suggesting specific, relevant actions linked to ratio evidence. Vague advice like "improve profitability" earns no marks; "negotiate bulk-buying discounts with suppliers to reduce cost of sales and increase gross profit margin" earns marks.
Show workings for all calculations — if your final answer is incorrect but your method is right, you gain partial marks. Write out formulae in full before substituting numbers. Round percentages to one decimal place unless told otherwise; express ratios like 1.5:1 or 1.83:1.
Quick revision summary
Financial statement analysis uses ratios to evaluate business performance. Profitability ratios (gross profit margin, net profit margin, ROCE) measure profit-generating efficiency. Liquidity ratios (current ratio, liquid ratio) assess ability to pay short-term debts. Calculate ratios using formulae, express correctly (% or :1), and interpret by comparing trends or competitors. Comment on whether results are satisfactory and recommend specific improvements. Recognize limitations: ratios use historical data, ignore qualitative factors, and vary by industry. Exam answers require accurate calculations with workings plus meaningful interpretation for full marks.
