How margin and markup differ

Margin vs. markup

Margin divides profit by the selling price; markup divides the same profit by the cost. The two match only when profit is zero, and grow further apart as the profit percentage increases.

Common uses

  • Price a product to hit a target margin.
  • Check whether a markup convention matches the margin your finance team expects.
  • Compare pricing strategies across products with different costs.

Worked example

A product costing $80 sold for $100 has $20 profit: a 20% margin (20/100) but a 25% markup (20/80) — the same profit, two different percentages.

Margin vs markup example

Profit
price - cost
Margin
profit / price * 100
Markup
profit / cost * 100

Cost 60, price 100

Profit is 40, margin is 40%, and markup is 66.67%.

Calculation notes

All math runs in your browser; the cost and price you enter are never sent anywhere.

Frequently Asked Questions

Why are margin and markup different for the same sale?

Margin is profit divided by price; markup is the same profit divided by cost. Since price is always higher than cost when there's a profit, markup is always the larger percentage.

What if cost is 0?

Markup would be undefined (division by zero), so the calculator shows a symbol for infinite markup instead of a number.

Which one should I use to set my price?

If your target is a percentage of revenue, use margin. If your target is a markup over cost (common in retail and manufacturing), use markup — plugging the same profit into the wrong formula will misprice the product.

Can I use this for investment return instead of retail pricing?

Yes. Switch the view to Investment (ROI): cost becomes your initial investment (plus any extra costs), price becomes the amount returned, and markup becomes ROI — the same formula, since ROI is profit divided by total cost. That view also adds a return multiple.
