Margin & Markup Formulas

Quick answer: Margin and markup are not the same thing.

This calculator helps you switch between cost, selling price, profit, gross margin %, and markup %.

  • Profit: Profit = Selling Price − Cost
  • Gross Margin %: Margin = (Profit ÷ Selling Price) × 100
  • Markup %: Markup = (Profit ÷ Cost) × 100
  • Selling Price from Margin: Price = Cost ÷ (1 − Margin Decimal)
  • Selling Price from Markup: Price = Cost × (1 + Markup Decimal)
Margin uses selling price as the base. Markup uses cost as the base.

FAQ

What is the difference between margin and markup?

Margin is profit as a percentage of selling price. Markup is profit as a percentage of cost. They use different bases, so the percentages are different.

Can margin be negative?

Yes. If your selling price is lower than your cost, profit becomes negative and your margin is negative.

Why is a 50% margin not the same as a 50% markup?

Because 50% margin means profit is half of selling price, while 50% markup means profit is half of cost.

Can I use this for products and services?

Yes. It works for product pricing, labor pricing, wholesale pricing, retail pricing, service quotes, and internal business planning.
