The main aim of all business enterprises is to earn profit. Moreover, earning profit is considered essential for business prosperity.
Profit is like the engine that drives the business forward. It is also the key to examining the efficiency of the company.
The following important formulae should be understood:
Gross Profit Ratio
This ratio measures the relationship of gross profit to net sales. In general, this percentage is calculated on sales.
The formula for the gross profit ratio is as follows:
GP ratio = (Sales - Cost of goods sold) x 100 / Net sales
Consider the following information and calculate the gross profit ratio:
- Net sales: $320,000
- Sales return: $20,000
- Cost of goods sold: $200,000
At the outset, we need to calculate net sales. This is calculated as follows:
Net sales = $320,000 - 20,000 = $300,000
To calculate the gross profit ratio, the following working is used:
GP = Net sales - Cost of goods sold
= 300,000 - 200,000 = $100,000
GP ratio = (GP x 100) / Net sales = (100,000 x 100) / 300,000
GP ratio = 33.33%
The operating ratio is useful to identify the relationship between the cost of goods sold and other operating expenses, on the one hand, and sales on the other hand. Here, operating cost is divided by net sales. In other words:
Operating ratio = (Operating cost x 100) / Net sales
Operating Cost = (Cost of goods sold + Operating exp.) x 100 / Net sales
Consider the following:
- Cost of goods sold: $300,000
- Selling exp.: $40,000
- Administrative. exp.: $60,000
- Total net sales: $600,000
Operating ratio = (Operating cost x 100) / Net sales $300,000 + 40,000 + 60,000 = 400,000 = 400,000 x 100 / 600,000 = 66.66%
Comment: Two-third of the sales are consumed by operating costs. The balance is to cover up the interest charges, income tax, dividends, and retention of profits.
Operating Profit Ratio
This ratio reflects how much of sales is consumed by operating costs. A higher operating ratio is always harmful because a small margin is left for interest, income tax, dividends, and reserves. It is a test of a company’s operating efficiency.
The operating profit ratio is calculated as follows:
Operating profit = Net sales - Operating cost or Net sales - Cost of goods sold + Operating cost
Net operating profit = Net profit + Non-operating exp. - Net operating income - Operating profit ratio
= 100 - Operating ratio
From the following information, calculate the operating profit ratio:
- Cost of goods sold: $400,000
- Administrative exp.: $30,000
- Selling exp.: $50,000
- Net sales: $600,000
Operating profit ratio = (Operating profit x 100) / Net sales = 600,000 - (400,000 + 30,000 + 50,000) = $120,000 Operating profit ratio = 120,000 x 100 / 600,000 = 20%
Various expenses are related to total net sales. The lower the expense ratio, the greater the profitability, whereas the higher the ratio, the lower the profitability. The expense ratio is calculated as follows:
Expense ratio = (Specific expenses x 100) / Net sales
Net Profit Ratio
The net profit ratio is calculated as follows:
Net profit ratio = (Net profit x 100) / Net sales
While calculating net profit, there are two schools of thought.
- Net profit after tax
- Net profit before tax
This ratio is very useful from the perspective of shareholders.
Return on Shareholders' Investment or Net Worth
To calculate ROI, use the following formula:
ROI = Net profit (after tax and interest) x 100 / shareholders’ funds
Here, net profit is defined as follows:
Net profit = Out of Profit - Interest and income
Also, to calculate shareholders’ funds, use the following formula:
Consider the following information:
- 20,000 equity shares at $10 each: $200,000
- 2,000 10% preference shares at $100 each: $200,000
- Total: $400,000
Reserved and Surplus
|Reserves for emergencies||30,000||100,000|
|Net profit before tax and interest||200,000|
Required: Calculate the return on shareholders’ investment.
Shareholder’s investment Share capital $200,000 + 200,000 + 100,000 = $500,000
|Net profit before interest and tax||200,000|
|Less: 50% tax||80,000|
Return on shareholders’ investment = Net profit after tax x 100 / Shareholders’ investment
= 80,000 x 100 / 5,00,000 = 16%
Comment: ROI is useful when measuring a company’s profitability, and so shareholders and management are interested in it. The greater the ratio, the higher the level of efficiency that the company has used shareholders’ funds.

Return on assets (ROA) reflects how efficient a company is in using its assets to generate profits. It helps an investor understand the profitability of the enterprise with reference to its total assets. Higher ROA usually indicates greater efficiency.
Operating profit ratio, also known as operating margin ratio, refers to the amount of money earned by a company through its operations expressed in percentage terms. It shows how much it costs for a company to make one dollar of revenue. This metric is especially useful when comparing profitability among different companies or industries with varying cost structures.
