Understanding Operating Profit Margin: A Quick Guide

Business Numbers Blog - Understanding Operating Profit Margin

When running a business, profitability is crucial. But profit isn't just a simple, one-size-fits-all term. You need to understand different profit margins, including operating profit margin, to make informed decisions. This quick guide will explain the operating profit margin and how it differs from gross and net profit.

What is Operating Profit Margin?

The operating profit margin is a measure of a company's profitability. It shows how much profit a business generates from its operations after deducting the cost of goods sold (COGS) and operating expenses.

It differs from your gross profit margin because it doesn't include other income or expenses, such as interest on loans, return on investments or taxes.

Net profit margin, on the other hand, represents a business's profit after deducting all expenses, including taxes.

Operating profit is simply measuring how much your business makes from its operations, ignoring other financial aspects.

Knowing your operating profit margin is important because it indicates how efficient your business is. A high margin means you're generating a lot of profit from your operations, and your business is running smoothly. On the other hand, a low margin could mean you need to sell more or your operating expenses are too high.

Calculating Operating Profit Margin

The first step in working out your operating profit margin is to calculate your operating profit.

To do this, you need to know your business's total revenue and cost of sales, as well as its operating expenses.

Operating expenses include things like rent, wages, utilities and insurance.

Once you have this information, you can calculate your operating profit by deducting your cost of sales and operating expenses from your total revenue.

For example, if your business had total revenue of $100,000 last year, your cost of goods sold was $50,000, and your operating expenses were $30,000, your operating profit would be $20,000.

To determine your operating profit margin, divide your operating profit by your total revenue and multiply the result by 100. So, in the example above, your operating profit margin would be 20%.

In summary, the formula for working out your operating margin is:

Operating Profit ÷ Total Revenue x 100 = Operating Profit Margin %


Comparing your operating profit margin against your gross and net profit margins is important.

Your operating margin will usually be lower than your gross profit margin because it doesn't include other forms of income, such as interest or investments.

However, it should be higher than your net profit margin because it doesn't take into account all expenses, including taxes.

 If your operating margin is lower than both your gross and net margins, it could be a sign that your business is inefficient or that your operating expenses are too high.

 It would be best to compare your operating profit margin year-on-year because a decline could indicate your business is becoming less profitable.

Factors that Impact Operating Profit Margin

Several factors can impact your operating profit margin, including:

  • Sales volume: An increase in sales volume can boost your operating profit margin.
  • Cost of sales: A decrease in the cost of sales can increase your margin.
  • Operating expenses: Decreasing your operating expenses can improve your margin.
  • Industry norms: Operating profit margins vary by industry, so comparing your margin to other businesses in your sector is crucial.

Final Thoughts

It's important to keep track of all your business's financial metrics, including operating profit margin.

By understanding your operating profit margin, you can get a good indication of how efficient and profitable your business is. You can also use it to compare your performance against other businesses in your industry.

Operating profit margins vary depending on the industry you're in. Some industries are naturally more profitable than others, so compare your margin to businesses in the same sector to get a more accurate idea of how you're faring.
