About the Margin Calculator

Profit margin is the fundamental measure of business profitability, and understanding the difference between margin (percentage of selling price) and markup (percentage of cost) is critical for any business owner. Our margin calculator computes gross profit margin, net profit margin, and markup percentage — plus lets you work backwards to find the selling price required to achieve a target margin.

How It Works

Gross Profit Margin = (Revenue − COGS) ÷ Revenue × 100. Markup = (Revenue − COGS) ÷ COGS × 100. Key insight: a 50% markup does NOT equal 50% margin. A product costing $10 with a 50% markup sells for $15, giving a 33.3% margin ($5 profit ÷ $15 revenue). To achieve a 50% margin on a $10 cost item, you need to price it at $20 (100% markup). Confusing these two destroys profitability.

Tips & Best Practices

• ✓Retail industry average gross margins: grocery 25%, apparel 50%, software 70–80%, restaurants 60–70%.
• ✓Don't set prices based on cost + markup alone — also consider competitor prices and perceived value.
• ✓Contribution margin (revenue minus variable costs) is more useful than gross margin for break-even analysis.
• ✓A price increase of just 1% with stable volume improves operating profit by 8–11% for average businesses.
• ✓High margins attract competitors; sustainable businesses combine reasonable margins with scale.
