How it works

Markup amount equals cost × markup percentage ÷ 100, and selling price adds that amount to cost. Margin is markup amount ÷ selling price × 100, so its denominator is revenue rather than cost.

  • A 30% markup on 50 is the editable illustration.
  • Tax, shipping, overhead, and target-margin conversion are excluded.

Worked example

Product Markup
Calculate selling price with a 40% markup on a $25 cost
Input
											Cost: 25
Markup percent: 40
Output
												Cost: $25.00
Markup: 40% (+$10.00)
Selling Price: $35.00
Profit Margin: 28.57%

When to use this

Retailers price from wholesale cost, craft sellers check gross margin, and quotes compare cost-plus percentages with selling prices.

Edge cases

  • A 30% markup produces a 23.08% margin, not 30%, because the denominators differ.
  • A negative markup lowers the selling price and is not automatically treated as a discount.
  • A zero or negative selling price makes margin meaningless even if arithmetic can be evaluated.
