Selling price

$1,250.00

$1,000.00 cost + $250.00 profit.

Markup

25.0%

Margin

20.0%

A 25% markup = 20.0% margin. They are not the same. Markup is measured against your cost; margin is measured against the price you charge.

Markup vs. margin: the formulas

Both describe profit, but they measure it against different bases:

  • Markup = (price − cost) ÷ cost
  • Margin = (price − cost) ÷ price
  • Margin from markup = markup ÷ (1 + markup)
  • Markup from margin = margin ÷ (1 − margin)

Worked example

Your cost is $1,000. You add a 25% markup, so you charge $1,250 and make $250. But $250 ÷ $1,250 is only a 20% margin. If you actually needed a 25% margin, you'd have to charge $1,333 — a 33.3% markup. That $83 gap on a single job becomes thousands across a year of underpricing.
