Unit 3.5: Profitability and Liquidity Ratios - IB Business Management

Profitability and Liquidity Ratios

Profitability and liquidity ratios help assess a business’s financial performance and condition over time. Students should be able to calculate each ratio, interpret what it indicates, and suggest ways to improve it.

Comparisons should be made cautiously: what counts as good performance can vary by industry.

Profitability ratios

Profitability ratios assess a firm’s ability to generate profit and can help investors consider the return they may receive.

• Gross profit margin Formula: Gross profit ÷ sales revenue × 100 Shows gross profit as a percentage of revenue and indicates how well the firm controls its direct costs. Include the percentage sign in answers.

• Return on sales Formula: Profit before interest and taxes (EBIT) ÷ sales revenue × 100 Shows EBIT as a percentage of revenue. Unlike gross profit margin, it reflects the effect of both direct and indirect costs.

• Return on capital employed (ROCE) Formula: EBIT ÷ capital employed × 100 Indicates how effectively the firm uses its long-term financing to generate profit. Capital employed includes equity and long-term liabilities or loans.

Ways to improve profitability: Increase revenue—for example, by adjusting prices or selling more—or reduce costs, such as the cost of sales, marketing expenses, or rent. Recommendations should be linked to the specific circumstances of the business being analyzed.

Liquidity ratios

Liquidity ratios measure whether a firm can use its current assets to pay its short-term liabilities. If it cannot meet these obligations, it may face a liquidity crisis.

• Current ratio Formula: Current assets ÷ current liabilities A guideline of 1.5:1 suggests that the firm has enough current assets to cover short-term debts, with some reserve. However, an unusually high ratio—such as 6:1 or 7:1—may suggest that assets are not being used efficiently and could potentially be invested in the business.

• Quick ratio (acid-test ratio) Formula: (Current assets − inventories) ÷ current liabilities This ratio excludes inventory because it may not be quickly converted into cash. For example, a bakery’s current ratio could appear healthy while much of its current assets consist of unsold goods that may spoil. The quick ratio focuses on more readily available assets, such as cash and accounts receivable. A guideline of 1:1 indicates enough highly liquid assets to cover current liabilities.

Ways to improve liquidity: Increase or make better use of current assets, such as by encouraging customers to pay in cash, or reduce current liabilities. A business might negotiate longer supplier credit periods, agree on payment schedules, or replace short-term borrowing with long-term loans.

Study and application advice

• Practice calculations and interpretation using case studies.
• Explain not only what a ratio’s value indicates, but also how and why it changes over time.
• Apply improvement strategies to the facts of a specific business rather than giving generic suggestions.
• Ratio analysis can also support the analytical section of a Business Management internal assessment.
