Gross margin vs markup: the mix-up that quietly costs you money

Your sales team says 30%. Finance says 23%. Nobody is lying. They're just using different words for different numbers.

The short version
  • Margin is profit as a share of the selling price. Markup is profit as a share of the cost.
  • Same product, same profit, two different percentages: margin is always the smaller one.
  • Pricing with a markup when you meant a margin gives away profit on every sale.

Same $30, two percentages

You buy a product for $70 and sell it for $100. You keep $30.

  • Gross margin = $30 ÷ $100 price = 30%
  • Markup = $30 ÷ $70 cost = 43%

Both are correct. Finance almost always talks in margin, because it links straight to the P&L: gross margin is gross profit divided by revenue. Sales and purchasing teams often talk in markup, because they start from the cost.

Illustrative figures. Same $30 of profit, expressed two ways.

Quick math: the pricing mistake

Your boss says "we need a 30% margin on this product." The product costs $70. You add 30% to the cost: $70 × 1.30 = $91.

Check the margin: you keep $21 on a $91 price. That's a 23% margin, not 30%. On every sale you've given away $9 of gross profit compared with the $100 price you needed (same cost, same number of sales).

The fix is one formula: price = cost ÷ (1 − target margin). Here: $70 ÷ 0.70 = $100.

The cheat sheet

  • Margin to markup: margin ÷ (1 − margin). A 30% margin is a 43% markup.
  • Markup to margin: markup ÷ (1 + markup). A 50% markup is a 33% margin.
  • A 100% markup (doubling the cost) is only a 50% margin.

In our course, Halvard's Pro machine sells for $11,000 and costs $6,600 to build. That's a 40% gross margin, or a 67% markup. Same machine, same $4,400 of profit.

Why it matters to you

If you set prices, approve quotes or negotiate with suppliers, agree the language before you agree the number. Many pricing disputes in budget meetings are really a margin-versus-markup misunderstanding. And once margin is clear, look at what a discount does to it: the true cost of a discount is usually much bigger than people expect.

From the finance director's chair

When a proposal says "30%", I ask "30% of what?" before anything else. It saves about ten minutes of confusion per meeting.

Ask Finance

"When we say margin, do we mean gross margin on the selling price, and what's our target by product?"
