Profit Margin & Markup Calculator (Gross & Net Profit %)
Calculate Gross Profit Margin, Net Profit, and Markup percentage from your selling price and cost of goods sold (COGS).
Profit Margin vs. Markup: GAAP Formulas & Benchmarks (2026)
How to calculate gross profit margin %, net profit margin, and cost-of-goods-sold markup with practical mathematical conversions and industry benchmarks.
Profit Margin is the percentage of total sales revenue retained as profit after deducting costs: (Profit ÷ Revenue) × 100. Margin can never exceed 100%. Markup is the percentage added on top of the cost of goods sold (COGS) to set the selling price: (Profit ÷ Cost) × 100. A product that costs $50 and sells for $100 has a 50% Gross Margin and a 100% Markup.
The Destructive Impact of Unplanned Discounting
Because fixed operating costs and product COGS stay static, offering a retail discount comes 100% out of your net profit margin. If a business operates at a 20% net margin, running a 10% flash sale slashes net profits by 50%, requiring twice the volume of sales simply to make the exact same dollar profit.

| Desired Gross Margin % | Required Markup % | Cost of Goods (COGS) | Target Retail Price | Gross Profit Kept |
|---|---|---|---|---|
| 20.0% | 25.0% | $100.00 | $125.00 | $25.00 |
| 33.3% | 50.0% | $100.00 | $150.00 | $50.00 |
| 50.0% | 100.0% | $100.00 | $200.00 | $100.00 |
| 75.0% | 300.0% | $100.00 | $400.00 | $300.00 |
| 80.0% (SaaS) | 400.0% | $100.00 | $500.00 | $400.00 |
Gross Margin % = ((Revenue − COGS) ÷ Revenue) × 100
Measures production and product sourcing efficiency before indirect administrative, payroll, and rent overhead.
Net Margin % = ((Revenue − COGS − Operating Expenses) ÷ Revenue) × 100
Measures true bottom-line enterprise profitability available for dividend distributions or capital reinvestment.
