Profit Margin Calculator

Calculate margin, markup, and profit from cost and revenue.

Margin vs. Markup

These two terms are often confused but mean very different things:

  • Profit Margin: Profit as a percentage of the selling price. "How much of the sale is mine?"
  • Markup: Profit as a percentage of the cost price. "How much did I add to the cost?"

Example

You buy a product for $100 and sell it for $150.

Profit = $50

Margin = (50 / 150) × 100 = 33.3%

Markup = (50 / 100) × 100 = 50.0%

Key Takeaway

Your markup percentage will always be higher than your margin percentage. Margin can never exceed 100%, but markup can be infinite.
