What Is Operating Margin? (eCommerce Definition)
Operating margin is EBIT divided by revenue: what is left after COGS and all operating costs, before interest and tax. For ecommerce operators, it is a cleaner signal than gross margin because it captures marketing and fulfilment overhead. Public DTC top quartile runs 14 to 22%. Private brands at 20M ARR should target 4 to 8%.
Operating margin is the percentage of revenue left as profit from the core operating business, after cost of goods sold and operating expenses, but before interest, tax, depreciation, and amortization adjustments. It is the cleanest view of "how profitable is the business model itself."
How operating margin is calculated
Operating margin (%) = Operating Income (EBIT) ÷ Revenue × 100
Operating income = Revenue − COGS (Cost of Goods Sold) − SG&A − R&D. Excludes interest expense, tax, and one-time items.
Example
A DTC brand with $40M revenue, $14M COGS, $20M operating expenses (SG&A + R&D). Operating income = $40M − $14M − $20M = $6M. Operating margin = $6M ÷ $40M = 15%.

The most common mistake
Comparing your operating margin to the public DTC median. The median is depressed because growth-stage brands capitalize spend through P&L. Use top-quartile (1422%) as the operational target, that is what mature, well-run brands actually run.
Frequently Asked Questions
is operating margin the same as EBIT margin?
Yes. EBIT (earnings before interest and tax) is operating income; EBIT ÷ revenue = operating margin.
what's the difference between operating margin and EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) margin?
EBITDA adds back depreciation and amortization. EBITDA margin is 1 to 5 points higher than operating margin. See What is EBITDA margin?
why don't most public DTC brands show high operating margins?
Most choose to reinvest in growth, which flows through P&L. Top-quartile public brands (14-22%) demonstrate what's achievable when growth and profitability are balanced.
