Profit Margin Calculator
Calculate your gross profit, profit margin, and markup from cost and selling price.
How it works
Subtract the cost price from the selling price to find gross profit. Divide that profit by the selling price, then multiply by 100.
Profit margin = (Selling price - Cost price) ÷ Selling price × 100
