Profit margin is the percentage of revenue remaining after subtracting costs. Gross margin considers only production costs; net margin accounts for all business expenses including taxes.
Three Types of Profit Margin
- Gross Margin: (Revenue − COGS) ÷ Revenue. Measures production efficiency.
- Operating Margin: (Revenue − COGS − Operating Expenses) ÷ Revenue. Measures operational efficiency.
- Net Margin: (Revenue − All Expenses) ÷ Revenue. The bottom-line profitability.
What Is a Good Margin
It varies by industry. Software: 70-80% gross, 20-30% net. Retail: 25-35% gross, 2-5% net. Restaurants: 60-70% gross, 3-9% net. Manufacturing: 25-35% gross, 5-10% net.
Real-World Example
A product sells for $100. COGS: $40. Operating expenses: $25. Taxes: $8. Gross margin: ($100-$40)/$100 = 60%. Operating margin: ($100-$40-$25)/$100 = 35%. Net margin: ($100-$40-$25-$8)/$100 = 27%.
Frequently Asked Questions
What is the difference between margin and markup?
Margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. A 50% markup on a $10 item means selling at $15. The margin on that same sale is 33% ($5 profit on $15 revenue). Margin is always lower than markup.
How can I improve profit margin?
Increase prices, reduce cost of goods (negotiate with suppliers, reduce waste), cut operating expenses, increase sales volume to spread fixed costs, or shift product mix toward higher-margin items.
Why do some businesses have low margins but high profits?
Volume. Walmart has a net margin of about 2-3% but generates $15+ billion in annual profit because revenue exceeds $500 billion. High-volume businesses can thrive on thin margins; low-volume businesses need higher margins.
