Whether you run a small business, freelance, or just want to understand your finances better, knowing how to calculate profit margin is one of the most valuable skills you can have. In this guide, we break down every type of margin with clear formulas and real examples — plus a free calculator to save you time.
What Is Profit Margin?
Profit margin is the percentage of revenue that remains as profit after costs are deducted. It tells you how efficiently a business (or product) is generating profit. A higher margin means more money kept per dollar earned.
The 3 Types of Profit Margin
1. Gross Profit Margin
Gross profit margin only subtracts the cost of goods sold (COGS) from revenue. It ignores operating expenses, taxes, and interest.
Formula: Gross Profit Margin = (Revenue − COGS) ÷ Revenue × 100
Example: Revenue = $50,000 | COGS = $30,000 → Gross Profit = $20,000 → Gross Margin = 40%
2. Operating Profit Margin
Operating margin subtracts COGS and operating expenses (salaries, rent, utilities) but excludes taxes and interest.
Formula: Operating Margin = Operating Income ÷ Revenue × 100
3. Net Profit Margin
Net margin is the most comprehensive — it deducts every single expense including taxes and interest. It is the true “bottom line” profitability.
Formula: Net Profit Margin = (Revenue − All Expenses) ÷ Revenue × 100
Example: Revenue = $100,000 | All Expenses = $82,000 → Net Profit = $18,000 → Net Margin = 18%
Profit Margin vs Markup: Don’t Confuse Them
One of the most common mistakes in business is confusing margin with markup. Margin is based on selling price; markup is based on cost. A 30% profit margin is NOT the same as a 30% markup.
Example: Cost = $70, Price = $100 → Margin = 30% | Markup = 42.86%

|---|---|
| Software / SaaS | 20–30% |
| Healthcare | 10–15% |
| Retail | 2–5% |
| Restaurants | 3–9% |
