Profit margin is a straightforward concept that represents the percentage of sales kept as profit. For example, if a company reports a 38% profit margin for the past quarter, it means it retained 38 cents from every dollar of sales. There are various types of profit margins, and understanding each one allows you to make informed pricing decisions, choose the right product mix, and adapt strategies to enhance financial performance.

This Ameris Bank Equipment Finance blog article provides a profit margin guide for business owners. We explain the three common types of profit margins—gross, net, and operating—detailing how they work and how to calculate them..


Gross profit margin.

Gross profit margin, commonly known as gross margin, is one of the simplest financial metrics to use because it excludes expenses such as payroll, rent, marketing, and taxes. Instead, it focuses solely on the product’s sales price minus the cost of goods sold (COGS). This makes gross profit margin an excellent choice if you want to come up with fast pricing for your products.

Gross profit margin formula.

Total revenue – COGS ÷ total revenue × 100

It only takes a few steps to calculate. First, subtract your COGS from your total revenue to find your gross profit. This number shows the profit you made from selling your products before accounting for expenses. Then divide this figure by your total revenue to obtain a decimal, and multiply it by 100 to convert it to a percentage. The resulting percentage is your gross profit margin.

Gross profit margin example.

Let’s consider a scenario in which your business generated $750,000 in revenue this year and your cost of goods sold (COGS) was $300,000. To calculate your gross profit, subtract COGS from your revenue: $750,000 – $300,000 = $450,000. Next, you divide the gross profit by your total revenue: $450,000 ÷ $750,000, resulting in 0.6. Finally, to express this as a percentage, multiply by 100: 0.6 x 100 equals 60%. Thus, your gross profit percentage is 60%.

Net profit margin.

Net profit margin, often referred to as net margin, is the profit that remains after all expenses have been subtracted from a company’s sales revenue. Since expenses are considered, the net profit margin gives a clear and accurate indication of a company’s profitability. Calculating the net profit margin is more complex than calculating the gross profit margin because it requires tracking all inflows and outflows of funds in the business. Therefore, it is essential to have an up-to-date income statement.

Net profit margin formula.

Net income ÷ total revenue × 100

Calculating the net profit margin is simple when the required financial information is readily available. To begin, determine your business’s net income, which is the total earnings after all expenses and taxes have been deducted. Next, divide this net income by the total revenue generated. Finally, multiply the result by 100 to express the net profit margin as a percentage. This percentage shows how much profit your company earns for every dollar of revenue.

Net profit margin example.

To illustrate how to calculate the net profit margin, let’s assume that your business generated $1.5 million in gross income this year and had $950,000 in expenses—$500,000 in cost of goods sold (COGS), $325,000 in operating expenses, $60,000 in loan payments, $40,000 in marketing fees, and $25,000 in business taxes. In this example, you need to subtract expenses from total revenue to get net income ($1,500,000 – $950,000 = $550,000).

After completing this step, divide the net income by the total revenue ($550,000 ÷ $1,500,000 = 0.366). To express this ratio as a percentage and determine the net profit margin, multiply the decimal result by 100. Thus, you would calculate 100 × 0.366, yielding a net profit margin of 36.7%.

Operating profit margin.

The operating profit margin reveals how much money a company retains after covering its operating expenses, including payroll, rent, and marketing, but before interest and taxes. This metric helps business owners evaluate the efficiency of their company’s core operations and understand the profit generated for each dollar of revenue. A high operating profit margin indicates that a business effectively manages its operating costs, while a low operating profit margin suggests the opposite.

Operating profit margin formula.

Operating income ÷ revenue × 100

To perform this calculation, you need to determine your company’s operating income before interest and taxes, referred to as earnings before interest and taxes (EBIT). You can calculate EBIT by subtracting operating expenses from revenue, which you can find in your company’s income statement. The calculation involves two steps: First, divide your company’s operating income by its total revenue. Next, multiply the result by 100 to express it as a percentage.

Operating profit margin example.

If your company had revenues of $5 million, cost of goods sold (COGS) of $2.5 million, and incurred expenses of $750,000, your operating income would be $1,750,000. The calculation is as follows: $5,000,000 (revenues) – $2,500,000 (COGS) – $750,000 (expenses) = $1,750,000 (operating income). To calculate your operating margin, divide your operating income by your revenues: $1,750,000 ÷ $5,000,000 = 0.35. Finally, to express your operating profit margin as a percentage, multiply this number by 100: 0.35 x 100 = 35%.

Conclusion

Whether you own a small business or a multi-million-dollar commercial enterprise, it is essential to understand profit margins and monitor this key financial metric regularly. By doing so, you can identify trends and areas for improvement, and make informed decisions that can enhance profitability.
