Enter cost and revenue to see your profit, margin and markup.
Margin = (Revenue − Cost) / Revenue × 100%. Markup = (Revenue − Cost) / Cost × 100%.
Cost $60, sell for $100 → Profit $40, margin 40%, markup 66.67%.
Profit margin is one of the clearest signals of business health. A healthy margin gives you room to reinvest, weather downturns and reward the team.
It varies by industry — 10% net margin is average, 20%+ is strong.
Retailers usually price with markup and report performance with margin.
