Many business owners think they’re more profitable than they actually are. The problem? They don’t calculate profit margin correctly.
Profit margin is simple in theory but frequently misunderstood in practice. This guide shows you exactly how to calculate it—and what to do if your margin is too low.
What Is Profit Margin?
Profit margin is the percentage of revenue that becomes profit. It answers one critical question: Of every dollar I make, how much do I actually keep?
Example: If you make $100,000 in revenue and keep $25,000 as profit, your profit margin is 25%.
Three Types of Profit Margin
1. Gross Profit Margin
Formula: (Revenue – Cost of Goods Sold) / Revenue × 100
Measures: Profitability before operating expenses (rent, salaries, utilities)
Example: You make $100,000 selling products that cost $60,000 to produce. Gross margin = ($100,000 – $60,000) / $100,000 = 40%
2. Operating Profit Margin
Formula: (Revenue – COGS – Operating Expenses) / Revenue × 100
Measures: Profitability after you pay for operations (but before taxes and interest)
Example: Your gross profit is $40,000, but operating expenses (rent, salaries, marketing) are $15,000. Operating margin = ($40,000 – $15,000) / $100,000 = 25%
3. Net Profit Margin
Formula: (Net Income / Revenue) × 100
Measures: Your actual bottom-line profit after everything
Example: After all expenses, taxes, and interest, you keep $20,000. Net margin = $20,000 / $100,000 = 20%
What’s a “Good” Profit Margin?
This depends on your industry:
- Retail: 5-10% net margin is healthy (high volume, lower margin)
- Service Businesses: 20-35% net margin (lower overhead)
- Software/SaaS: 40-70% net margin (highly scalable)
- Ecommerce: 10-25% net margin (depends on product type)
- Restaurants: 3-9% net margin (high overhead, thin margins)
How to Improve Your Profit Margin
