Profitability ratios help show how well a business is doing and they are focused on profit, capital employed and total revenue. The profit figure alone is not a useful performance indicator because it is necessary to look at the value of profit in relation to the value of turnover or the amount of money that has been invested in the business.

Gross profit margin

Shows the gross profit made on sales turnover.

$Gross profit margin = \frac{Gross profit}{Sales revenue} × 100$

Higher gross margins are preferable to lower ones. It is possible to rise the gross profit margin by raising turnover relative to cost of sales, for example, by increasing price. Note: Businesses that have high stock turnover tend to have lower gross profit margin compared to those businesses whose stock turnover is lower.

Improving gross profit margin

Raise revenue.
Reduce direct costs.

Net profit margin

Measures how well a business controls its overheads and cost of sales. If the difference between gross margin and net margin is small, this suggests that overheads are low. This is because net profit equals gross profits less overheads.

$Net profit margin = \frac{Net profit before interest and tax}{Sales revenue} × 100$

Again, higher margin is better than lower.

Improving net profit margin

Negotiate payment terms with creditors and suppliers. This may improve working capital.
Negotiate discounts for paying creditors on time.
Negotiate cheaper rent.
Reduce indirect costs such as not playing for first class, or reducing advertising or stationary.

Return on capital employed (ROCE)

Compares the profit made by the business with the amount of money invested. If the return is high, this means that the business is profitable, which would yield high dividends that current shareholders and potential investors are on the lookout for.

ROCE = \frac{Net profit before interest and tax}{Capital employed} × 100

The higher the ROCE, the bigger the return.

Improving ROCE

Reduce the amount of capital employed (i.e., loan less money).
Increase profitability of the company.

Profitability Ratios: A Deep Dive

Profitability ratios are crucial indicators of a business's financial health, focusing on profit, capital employed, and total revenue. These ratios provide insights into how well a business is performing by comparing profit figures to turnover and investments.

Gross Profit Margin

The Gross Profit Margin shows the gross profit as a percentage of sales revenue. It is calculated as:

Gross Profit Margin = (Gross Profit / Sales Revenue) × 100

Higher gross margins indicate better performance, and businesses can improve this ratio by increasing sales or reducing the cost of goods sold.

Net Profit Margin

The Net Profit Margin measures how effectively a business controls its overheads and cost of sales. It is calculated as:

Net Profit Margin = (Net Profit before Interest and Tax / Sales Revenue) × 100

A higher net profit margin is preferable, and businesses can improve it by negotiating better payment terms, reducing indirect costs, and managing overheads efficiently.

Return on Capital Employed (ROCE)

ROCE compares the profit made by the business with the capital invested. It is calculated as:

ROCE = (Net Profit before Interest and Tax / Capital Employed) × 100

A higher ROCE indicates a more profitable business. Improvements can be made by reducing capital employed or increasing profitability.

Real-Life Examples and IB Exam Pattern

Here are examples similar to what might be found on an IB exam:

Example 1: Retail Industry

A retail company reports a gross profit of $500,000 and sales revenue of $1,000,000. Calculate the Gross Profit Margin.

Answer: Gross Profit Margin = ($500,000 / $1,000,000) × 100 = 50%

Example: Electronics Manufacturer

An electronics manufacturer reports the following financial figures:

Sales Revenue: $2,000,000
Gross Profit: $800,000
Net Profit before Interest and Tax: $300,000
Total Capital Employed: $1,500,000

Calculate the Gross Profit Margin, Net Profit Margin, and Return on Capital Employed (ROCE).

Gross Profit Margin:

Gross Profit Margin = (Gross Profit / Sales Revenue) × 100

Gross Profit Margin = ($800,000 / $2,000,000) × 100 = 40%

This means that 40% of the sales revenue is gross profit.

Net Profit Margin:

Net Profit Margin = (Net Profit before Interest and Tax / Sales Revenue) × 100

Net Profit Margin = ($300,000 / $2,000,000) × 100 = 15%

This indicates that 15% of the sales revenue is net profit.

Return on Capital Employed (ROCE):

ROCE = (Net Profit before Interest and Tax / Capital Employed) × 100

ROCE = ($300,000 / $1,500,000) × 100 = 20%

A 20% ROCE indicates a healthy return on the capital invested in the business.

Conclusion

Understanding profitability ratios is essential for IB Business Management students. These ratios not only reflect a company's financial performance but also guide strategic decision-making.
