10.7 - Profitability Ratios
The meaning and importance of profitability
Profitability refers to how effectively a business generates profit relative to its sales or invested capital, rather than just the total profit amount. It provides a clearer picture of performance, as high profits might not indicate strong efficiency if sales or capital are also very large.
Key aspects of profitability:
- Profitability compares profit to revenue or capital to evaluate business success.
- Higher profitability increases the likelihood of better returns for investors.
- It is a more reliable measure of performance than raw profit figures, helping to assess management efficiency.
Gross profit margin ratio
The gross profit margin ratio evaluates how well a business turns revenue into gross profit by considering the cost of sales. It highlights management's ability to add value to direct costs.
Formula for gross profit margin ratio
Where:
- Gross profit = Revenue minus cost of sales (£)
- Revenue = Total income from sales (£)
Factors affecting gross profit margin
- A lower margin might stem from strategies like low pricing or higher per-unit costs, such as increased material or direct labour expenses.
- This ratio shows how effectively value is added to the cost of sales.
- Comparisons across industries can be misleading due to varying risks and typical margins.
Worked example - Calculating gross profit margin ratio
A business has revenue of £200,000 and gross profit of £80,000. Calculate the gross profit margin ratio.
Step 1: Identify the values
- Gross profit = £80,000
- Revenue = £200,000
Step 2: Apply the formula
Step 3: Perform the calculation
Operating profit margin ratio
The operating profit margin ratio measures a business's success in converting revenue into profit after accounting for all operating expenses. It reflects overall management effectiveness in controlling costs.
Formula for operating profit margin ratio
Where:
- Operating profit = Gross profit minus overhead expenses (£)
- Revenue = Total income from sales (£)
Significance of operating profit margin
- Operating profit is found by deducting overheads from gross profit.
- Trends in this ratio over time reveal how well revenue is turned into profit after all costs.
- A rising trend indicates improving management efficiency.
Worked example - Calculating operating profit margin ratio
A company reports revenue of £250,000 and operating profit of £50,000. Calculate the operating profit margin ratio.
Step 1: Identify the values
- Operating profit = £50,000
- Revenue = £250,000
Step 2: Apply the formula
Step 3: Perform the calculation
Return on capital employed ratio (RoCE)
Return on capital employed (RoCE) is the primary measure of business profitability, comparing operating profit to the capital invested. It is often called the primary efficiency ratio and helps assess returns on investments.
Formula for return on capital employed ratio
Where:
- Operating profit = Profit from operations (£)
- Capital employed = Non-current liabilities + shareholders' equity (£), where shareholders' equity = issued shares + reserves
Interpreting RoCE
- Higher ratios indicate better returns on invested capital.
- Compare with other firms, past performance, or interest rates to identify trends.
- If RoCE is below borrowing interest rates, additional loans could lower shareholder returns.
- Improving RoCE involves more efficient asset use or higher profits.
Worked example - Calculating return on capital employed ratio
A firm has operating profit of £60,000 and capital employed of £300,000. Calculate the RoCE.
Step 1: Identify the values
- Operating profit = £60,000
- Capital employed = £300,000
Step 2: Apply the formula
Step 3: Perform the calculation
Methods of improving profitability
Businesses can enhance profitability through strategies targeting profit margins or RoCE. These methods often involve cost reductions or efficiency gains, but they come with potential drawbacks.
Methods to increase profit margins
Reduce direct costs:
- Use cheaper materials.
- Evaluation: This could harm product quality and damage the business's reputation.
- Lower labour costs, such as relocating production to countries with lower wages.
- Evaluation: Communication issues may arise, risking product quality.
- Boost productivity via automation.
- Evaluation: Initial equipment costs raise overheads, and staff retraining is needed.
- Cut employee pay.
- Evaluation: This might reduce motivation, leading to lower productivity and quality.
Increase prices:
- Raises profit per unit sold.
- Evaluation: Sales may fall if customers switch to rivals, depending on price elasticity.
Reduce overhead costs:
- Relocate to cheaper premises.
- Evaluation: Could affect brand image if location is key to prestige.
- Cut marketing spending.
- Evaluation: Sales might drop more than the savings achieved.
- Flatten management structure.
- Evaluation: May impair decision-making and efficiency.
- Reduce long-term debt, perhaps by issuing shares.
- Evaluation: Depends on market confidence in the business's future.
Methods to increase RoCE
Boost operating profit without raising capital employed:
- Implement price rises.
- Evaluation: Effectiveness hinges on customer price sensitivity.
- Lower unit costs.
- Evaluation: Quality might suffer as a result.
- Trim administrative costs.
- Evaluation: Short-term gains could lead to longer-term sales declines.
Reduce capital employed:
- Sell off underused assets and use funds to pay down debt.
- Evaluation: These assets might be vital for future expansion.
