Operating Profit Margin

An operating profit margin – a.k.a. an operating or earnings before income and tax (EBIT) margin – is a key profitability ratio. It shows, for a given period, what proportion of every dollar worth of sales a company makes is left over as profit after costs related to directly operating the company are paid (e.g. production of goods, staff costs, marketing). A higher profit margin is better.

Why should I care about operating profit margins?

For markets: Operating profit margins are a key indicator for investors to gauge a company's financial health and operational efficiency. A stable or increasing operating profit margin suggests that a company is managing its costs well and generating more profits from sales, which can positively influence its stock price.

For you personally: Understanding operating profit margins can help you make informed investment decisions. For instance, companies with high margins are often capable of offering consistent shareholder returns and have greater flexibility than lower-margin companys to withstand a downturn in sales. And while these characteristics are typically reflected in a company’s valuation, such companies may be particularly attractive to risk-averse investors.

How do you calculate a company’s operating profit margin?

Here’s a step-by-step method to calculate operating profit margins:

Identify key components: You’ll need the total revenue for the period, the cost of goods sold (COGS), and other operating expenses from a company’s income statement or profit-and-loss account.

Determine operating profit: Subtract COGS and operating expenses from the total revenue. This figure is your operating profit.

  • Operating profit = Revenue – COGS – operating expenses

Calculate the operating profit margin: Divide the operating profit by revenue to find the profit margin as a percentage. Use the formula:

  • Operating profit margin = (Operating profit / revenue)

What’s the difference between operating margins, gross margins, and net margins?

Operating margins measure profitability after paying expenses related to the day-to-day running of a company’s core operations, but before costs like interest or tax – which companies have to pay but aren’t necessarily anything to do with the product or service it provides. It indicates how profitable the company is from its core activities.

Gross margins measure profitability after what’s known as “direct costs”, related to the production or provision of the company’s product or service. If a company buys a widget for $10 and sells it for $20, its gross profit would be $20 minus $10, which equals $10. In this way, gross margins are a strong reflection of a company’s “pricing power” – its ability to charge more for its products to counteract its own rising prices (the widget costing the company $12 rather than $10) or to boost profitability (customers like the widget so much, they’d pay $22).

Net margins measure company profitability after taking all costs into account, including interest payments and taxes. In that way a net profit margin is the most comprehensive measure of profitability. However it also reflects costs that aren’t necessarily associated with the core business and can therefore be both volatile and misleading year to year or quarter to quarter.

What are the limitations of operating profit margins?

The operating profit margin, while useful, has several limitations that can affect its usefulness and reliability as a measure of a company's financial health.

  • Industry variability: Different industries or business models within them have inherently different cost structures, which can skew comparisons without appropriate industry-specific benchmarks. In other words, it may make sense to compare profit margins of businesses in the same industry and that work in similar ways, but it’s a less useful way to compare businesses in different industries.
  • Non-cash expenses: Accounting costs that are “non-cash” items like depreciation and amortization are included in operating expenses. They don't impact company cash flow but can distort profitability measures.
  • Capital expenditures (capex): The other side of the depreciation coin is capex – cash expenses that aren’t included in operating profit margin calculations. Overlooking capex, which necessary for long-term growth and maintenance, potentially misrepresenting a company’s financial sustainability.
  • Accounting practices: Changes in accounting methods or financial adjustments can affect operating profit, making it a less reliable metric.
  • “Below the line” items: Costs like interest and tax do affect how investors should think about companies but aren’t reflected in profit margin analysis. For instance, two companies in the same industry, doing the same thing, with the same profit margin but with different tax rates have different amounts of cash left over to grow the business or pay shareholders – and should therefore be valued differently. Similarly, if one company has much higher interest expenses than the other, all else equal, investors would likely treat them differently.
  • Non-recurring items: One-off costs like restructuring can distort profit margins in a given period. Expert analysts tend to “adjust” their figures to remove these distortions otherwise it can prove a limitation to analyzing operating profit margins.

How can companies improve their operating profit margins?

Improving profitability ultimately comes down to doing one of two things – and often both.

  • Reduce costs: For example, by streamlining the business, negotiating better terms with suppliers, or adopting more efficient technologies.
  • Increase sales: Selling more of a given product or service will help improve profitability by driving “operating leverage” on certain costs. For instance, a particularly effective marketing campaign which boosts demand over and above the amount spent on it. However, the biggest sales driver that impact profit margins is pricing. Companies can increase the prices of their products and hope there’s not a drop-off in demand, boosting margins. They can also do this via product mix, whereby changing the types (or mix) of products on offer – like a slightly smaller product at the same price as the bigger one – can increase the effective price customers pay per item. All else equal, that will improve a company’s profit margin.

Frequently Asked Questions on Operating Profit Margins (FAQs)

What does a 30% operating profit margin mean?

A 30% operating profit margin means that for every dollar generated in revenue, the company retains 30 cents as operating profit after covering variable costs and operating expenses. This is generally considered a strong margin, indicating effective cost management and a potentially competitive position within the industry.

What is a good operating profit margin?

A “good” operating profit margin varies by industry, company size, and business model. High-margin industries like software may see averages well above 20%, whereas low-margin sectors like grocery retail might average much lower, say 5%. Generally, a good margin exceeds the industry average, aligns with company growth objectives, and reflects efficient operations relative to peers. For S&P 500 companies, the average operating profit margin is 18.2%

Can an operating profit margin be negative?

Yes, profit margins can be negative when a company's operating costs exceed its revenues. This situation often indicates issues like excessive spending, poor pricing strategies, or declining sales, and if sustained, it can threaten the company’s financial stability.

Is the operating profit margin the same as an EBITDA margin?

No. Operating profit margins measure profitability after operating expenses, inclusive of accounting costs like depreciation and amortization, but exclusive of interest and taxes. EBITDA, however, is earnings before interest, tax, depreciation, and amortization – and its margin, therefore, excludes items that are included in operating profit. A company’s EBITDA margin is a closer indication of its cash profitability than its operating profit margin. but excluding non-cash expenses.
