Operating Margin Calculator — EBIT Margin
Enter revenue, cost of goods sold and operating expenses to instantly calculate your operating margin — the percentage of revenue that remains as operating income (EBIT) after all production and overhead costs, before interest and taxes.

How does this calculator work?
Operating Margin = (Revenue − COGS − Operating Expenses) / Revenue × 100%. It shows what fraction of revenue survives all operating costs before interest and tax. Calculate gross profit first (Revenue − COGS), then deduct operating overhead to get EBIT. Compare against industry peers — context matters more than any single benchmark.
Formula
How this is calculated
Operating margin (also called EBIT margin — Earnings Before Interest and Tax) answers a fundamental question: for every dollar of revenue, how much profit does the business generate from its core operations, before the effects of how it is financed (interest) or how it is taxed? It is calculated in two steps: first subtract the cost of goods sold (COGS — direct production costs) from revenue to get gross profit; then subtract operating expenses (SG&A, R&D, depreciation, amortisation) to get operating income. Dividing operating income by revenue and multiplying by 100 gives the margin as a percentage.
Operating margin is especially useful for comparing companies of different sizes in the same industry, because it is a ratio rather than an absolute number. A 20% operating margin means $0.20 of operating income per $1.00 of revenue regardless of whether the business is small or large. Software and pharmaceutical companies typically achieve margins of 20–40%; grocery retailers often operate on 1–5%. Over time, a rising margin indicates improving efficiency or pricing power; a falling margin may signal cost pressures or pricing competition.
This calculator does not include interest expense, income tax, or non-recurring items (restructuring charges, gains/losses on asset sales). Those are below-the-line items that appear after operating income on the income statement. For a full bottom-line view, use a net profit margin calculator.
Frequently asked questions
Gross margin = (Revenue − COGS) / Revenue. It covers only direct production costs. Operating margin additionally deducts operating expenses (salaries, rent, R&D, depreciation) that are necessary to run the business but not tied directly to making each unit. Operating margin is therefore always lower than (or equal to) gross margin and gives a fuller picture of profitability.
It varies enormously by industry. Technology/software companies often show 20–40%+. Industrial manufacturers typically range 5–15%. Grocery retail may be 1–5%. The most meaningful comparison is against direct competitors in the same sector and against the company's own historical trend. Consistently improving margin signals operational leverage.
Interest depends on how the business is financed (debt vs. equity) and tax rates vary by jurisdiction and year — neither reflects how well the core operations are managed. Excluding them makes it easier to compare companies with different capital structures or in different tax regimes, and to focus on the profitability of the underlying business model.
