Your complete guide to using a Profit Margin Calculator — how to calculate gross margin, net margin, operating margin, and markup for any business in the USA, UK, Canada, and Australia. By Rajesh Kumar Ram
Profit margin is the single most important metric for any business — it tells you how much of every revenue dollar you actually keep as profit. Whether you're running an ecommerce store, an Amazon business, a restaurant, or a professional services firm, understanding and calculating your profit margins is essential for pricing, cost control, and growth planning. Use our free Profit Margin Calculator to compute all your margins in one place.
The Four Key Profit Margin Formulas
Gross Profit = Revenue − COGS
Gross Margin % = (Gross Profit / Revenue) × 100
Operating Profit = Gross Profit − Operating Expenses
Operating Margin % = (Operating Profit / Revenue) × 100
EBITDA = Operating Profit + Depreciation + Amortization
EBITDA Margin % = (EBITDA / Revenue) × 100
Net Profit = Operating Profit − Interest − Taxes
Net Margin % = (Net Profit / Revenue) × 100
Markup % = (Gross Profit / COGS) × 100
Break-Even Revenue = Fixed Costs / Gross Margin %
Profit Margin Worked Example
A US ecommerce business with:
- Revenue: $500,000/year
- COGS (products, shipping, fulfillment): $280,000
- Operating expenses (marketing, software, team, rent): $150,000
- Depreciation: $10,000
- Interest expense: $5,000
- Tax (25%): applied to pre-tax profit
Calculation:
- Gross Profit: $500,000 − $280,000 = $220,000 → Gross Margin: 44%
- Operating Profit: $220,000 − $150,000 = $70,000 → Operating Margin: 14%
- EBITDA: $70,000 + $10,000 = $80,000 → EBITDA Margin: 16%
- Pre-tax profit: $70,000 − $5,000 = $65,000 → Tax: $16,250
- Net Profit: $48,750 → Net Margin: 9.75%
- Markup: ($220,000 / $280,000) × 100 = 78.6%
