Operating Margin Calculator
Calculate operating margin (EBIT margin) from operating income and net revenue, or derive operating income from cost of goods sold and operating expenses. Compare a prior period and test a target margin.

Operating margin formula
Operating margin = operating income (EBIT) ÷ net revenue × 100%. EBIT is revenue after cost of goods sold and ordinary operating expenses, but before interest and income tax. With the statement method, EBIT = net revenue − COGS − operating expenses.
Total operating costs equal revenue minus EBIT. For a target, required operating income = net revenue × target margin; the gap is required operating income minus current EBIT.

| Inputs | Calculation | Result |
|---|---|---|
| $1,200,000 revenue and $180,000 EBIT | $180,000 ÷ $1,200,000 × 100 | 15.00% operating margin |
| $1,200,000 revenue, $720,000 COGS and $300,000 operating expenses | $1,200,000 − $720,000 − $300,000 | $180,000 EBIT and 15.00% margin |
| Prior margin 13.50%; current margin 15.00% | 15.00 − 13.50 | +1.50 percentage points; +11.11% relative |
| $1,200,000 revenue and 18.00% target | $1,200,000 × 18% | $216,000 required EBIT; $36,000 gap |
Operating margin, gross margin and EBITDA margin
Gross margin subtracts only cost of goods sold. Operating margin also subtracts operating expenses and therefore measures profit from core operations before financing and income tax. EBITDA margin adds depreciation and amortization back to EBIT, so it is usually higher than operating margin when those expenses are positive.
Inputs, limits and interpretation
- Net revenue must be greater than zero. Monetary inputs accept ordinary decimal notation, up to two decimal places and a magnitude no greater than 1,000,000,000,000.
- Operating income may be negative or zero. COGS and operating expenses cannot be negative; they may exceed revenue and produce a valid operating loss.
- The optional target accepts −1,000% through 1,000%. The calculation holds current revenue constant and does not forecast how costs would change.
- Enter both prior-period fields or leave both blank. Use consistent accounting classifications and periods before comparing results.
- The currency selector only changes number formatting. It does not convert currencies.
- This educational result does not adjust for unusual items, discontinued operations, industry-specific accounting or management-defined non-GAAP measures.
A higher margin can reflect pricing, volume, product mix or cost control, but it is not automatically better across unrelated industries. Compare the same definition over time and against relevant peers.
Frequently asked questions
Is operating margin the same as EBIT margin?
Usually, yes. When operating income and EBIT are defined the same way, both divide that amount by net revenue. Company presentations can use adjusted definitions, so reconcile the numerator.
Can operating margin be negative?
Yes. A negative result means operating costs exceeded net revenue for the period.
Should interest expense be included?
No. Operating margin is calculated before financing costs and income tax. Interest belongs below operating income under the standard formula used here.
