Operating margin is one of the most useful profitability metrics for comparing companies across industries. It focuses on the profit a business generates from its core operations before interest and taxes, making it a practical way to evaluate operating efficiency and pricing power. Because industries have different cost structures, competitive dynamics, and capital requirements, average operating margins can vary substantially from one industry to another.
The operating margin measures operating income as a percentage of revenue. It shows how much of each dollar of sales remains after a company pays for the direct costs of producing its goods or services and its operating expenses.
Operating Margin (%) = Operating Income / Revenue
Operating margin sits between gross margin and net margin in the profitability stack. It is broader than gross margin because it includes selling, general, and administrative expenses, but narrower than net margin because it excludes interest expense and taxes. That makes it especially useful when comparing businesses with different financing structures but similar operations.
The average operating margins can vary significantly across different industries. Here is a table of some common company industries in the US and their average operating margins as of Jun 2026:

Operating margins vary widely because industries incur different operating costs to generate revenue. Asset-light software and service businesses can often convert a larger share of revenue into operating profit, while industries with high labor, logistics, or maintenance costs may operate on thinner margins even when demand is healthy.
Competitive intensity also matters. Industries with differentiated products, recurring revenue, or high switching costs may maintain stronger operating margins because they have more pricing power. By contrast, commodity-like industries or markets with heavy price competition often show lower operating margins because companies must absorb cost increases or compete aggressively on price.
Software and digital platform businesses often post high operating margins once they reach scale. After the initial investment in development and infrastructure, each additional customer can generate revenue with relatively low incremental cost. That operating leverage can translate into strong margins, especially for companies with subscription-based revenue and limited distribution costs.
Retailers and distributors frequently operate with lower operating margins because they face higher fulfillment, labor, and overhead costs while competing in price-sensitive markets. Even if sales volumes are large, margin pressure from inventory management, transportation, and store or warehouse expenses can limit operating profitability.
Compared with gross margin, operating margin gives a more complete picture of operating efficiency because it includes overhead and operating expenses beyond direct production costs. Compared with EBITDA margin, operating margin is more conservative because it includes depreciation and amortization. And compared with net margin, it removes the effects of financing decisions and taxes, which can make peer comparisons cleaner.
When investors analyze a company’s operating margin, they typically compare it with industry averages and with the company’s own historical trend. A rising operating margin can suggest improving efficiency, better pricing discipline, or greater scale. A declining operating margin may signal rising input costs, operational inefficiencies, or weakening competitive positioning.
Operating margin should still be used together with other metrics. It does not capture capital intensity, working-capital demands, or non-operating risks, and it can be influenced by temporary cost actions. A strong analysis usually combines operating margin with revenue growth, cash flow, return metrics, and a review of the company’s cost structure.
