Margin to Markup Converter

Enter a profit margin percentage to get the equivalent markup percentage.

How it is calculated

Gross margin is profit as a share of the selling price; markup is profit as a share of the cost. Since cost = price − profit, the two are linked by markup = margin ÷ (1 − margin), with both written as fractions (the tool takes the margin as a percentage and multiplies back by 100). Enter the margin as a plain percentage, for example 35 for 35%. The result is always larger than the margin, because the same profit is divided by a smaller number. A margin of 0 gives 0, and 50 gives exactly 100. Margins below 0 or at 100 and above return nothing: a 100% margin would mean a cost of zero and an infinite markup. The tool converts one number into the other; it does not know your actual price or cost.

Worked example

You want a 35% margin. Written as a fraction that is 0.35, so the cost is 1 − 0.35 = 0.65 of the price. Markup = 0.35 ÷ 0.65 ≈ 0.5385, which is 53.85%. Check with money: a product that sells for $100 with a 35% margin has $35 profit and $65 cost, and $35 ÷ $65 = 53.85%. So to hit a 35% margin you must add 53.85% on top of cost, not 35%.

Common mistakes

  • Adding the margin percentage on top of cost. A 35% markup on a $65 cost gives a price of $87.75 and a margin of only 25.9%, not 35%.
  • Entering a fraction (0.35) instead of a percentage (35). The tool would read it as a margin of 0.35%.
  • Typing a markup into the margin field. Use this tool only to go from margin to markup; the reverse conversion is a different formula.
  • Expecting a margin of 100% or more to work. Margin cannot reach 100% because cost would have to be zero.
  • Mixing gross margin with net margin. This conversion only applies to a margin measured on selling price against cost of the product, before overheads.

About this calculator

Margin and markup both measure profit, but relative to different bases: margin expresses profit as a percentage of the selling price, while markup expresses it as a percentage of the cost. Because of this, a fixed dollar profit produces two different percentages, and the two figures are easy to mix up when pricing products.

This tool converts a margin percentage into its equivalent markup using markup = margin ÷ (1 − margin) — for example, a 25% margin converts to a 33.3% markup. Retailers, wholesalers and finance teams use the conversion to translate between margin-based pricing targets and markup-based cost-plus pricing without redoing the underlying math each time.
