Profit margin vs markup: the difference that costs shops money

By the Sumtrail editorial team. Published 3 October 2026. Last updated 3 October 2026.

Many shop owners mix up margin and markup. The result is prices that bring in less profit than planned.

The difference

  • Markup is profit as a percentage of the cost.
  • Margin is profit as a percentage of the selling price.

Buy at 1,000 and sell at 1,500: profit is 500. Markup is 500 ÷ 1,000 = 50%. Margin is 500 ÷ 1,500 = 33.33%.

Pricing for a target margin

To get a 25% margin, divide the cost by 0.75, not multiply by 1.25. A cost of 1,000 needs a price of 1,333.33. Multiplying by 1.25 gives 1,250, which is only a 20% margin.
