Operating Profit Margin Formula
Alternatively: Operating Margin = (Revenue − COGS − Operating Expenses) ÷ Revenue × 100
Full formula details appear on the profit margin formula page. The step-by-step process is covered on the how to calculate profit margin page.
What Counts as Operating Expense
Salaries and wages (non-production), rent, marketing and advertising, software subscriptions, utilities, insurance, office supplies, professional fees, depreciation of operating assets, and similar day-to-day costs. Interest and income taxes are excluded from the operating calculation.
Practical Example
Revenue $48,000 · COGS $19,200 · Operating expenses $21,500
Gross profit $28,800 · Operating income $7,300 → Operating margin ≈ 15.2 %
Compare this with the higher gross margin (60 %) on the gross profit margin calculator page and the lower net margin (≈ 12.9 %) on the net profit margin calculator page. The gap between gross and operating margin reveals the weight of operating costs.

Frequently Asked Questions
What is operating profit margin?
Operating profit margin is operating income divided by revenue, expressed as a percentage. It measures profitability after cost of goods sold and operating expenses but before interest and taxes.
How do you calculate operating profit margin?
Operating Margin = Operating Income ÷ Revenue × 100. Operating Income = Gross Profit − Operating Expenses.
What are operating expenses?
Costs of running the business that are not direct product costs: salaries (non-production), rent, marketing, software, utilities, insurance, depreciation and similar items.
How does operating margin differ from net margin?
Operating margin excludes interest and taxes. Net margin includes them. Operating margin therefore reflects the efficiency of core operations more cleanly.
