How margin and markup convert
Markup and margin describe the exact same dollar profit on a sale, but as a percentage of two different base numbers. Markup is profit divided by cost: markup% = (price − cost) ÷ cost. Margin is profit divided by the selling price: margin% = (price − cost) ÷ price. Because price is always larger than cost (assuming any profit at all), margin is always the smaller percentage of the two.
The conversion formulas are: margin = markup ÷ (1 + markup) and markup = margin ÷ (1 − margin) (both as decimals). These are worth memorizing for quick mental conversion — a 50% margin always corresponds to exactly a 100% markup, a useful anchor point since both describe doubling the cost to set the price.
Margin/markup conversion formulas are standard retail and cost-accounting relationships.
Worked example
A retailer knows their markup is 150% and wants the equivalent margin.
Real-world context
This mix-up causes real confusion in clothing retail negotiations and financial reporting: a buyer who says "we need at least a 50% margin" and a supplier who quotes "our standard markup is 50%" are describing very different profitability — the buyer's 50% margin equals a 100% markup, while the supplier's 50% markup only equals a 33% margin, a substantial gap that can derail a pricing conversation if the two sides aren't using the same term.
Financial statements and gross-profit reporting almost always use margin (percentage of revenue), since that's what maps directly to total company profitability, while day-to-day pricing decisions on the retail floor are more often expressed as markup, since it's the more intuitive "add this much to what I paid" framing for setting a shelf price.
Common misconceptions
"Margin and markup are just two names for the same percentage." They're numerically different. Except at 0%, markup is always a larger number than margin for the identical transaction, because of the different denominators.
"You can average or add margin and markup together." They shouldn't be mixed directly. Always convert to the same measure first — averaging a 50% margin and a 60% markup as if they're the same unit produces a meaningless number.

Frequently asked questions
What's the actual difference between margin and markup?
Margin is profit as a percentage of the selling price: profit ÷ price. Markup is profit as a percentage of cost: profit ÷ cost. Same dollar profit, two different percentages, because they divide by different numbers.
Why is a 100% markup only a 50% margin?
If cost is $20 and markup is 100%, profit is $20 and price is $40. Margin is profit ÷ price = 20 ÷ 40 = 50%. Markup uses the smaller number (cost) as its denominator, so markup percentages are always higher than the margin percentage for the same transaction, once above 0%.
Can margin ever be 100% or higher?
Margin can approach but never reach 100%, since that would mean zero cost. Markup, by contrast, has no upper limit — a very high markup (say, 900%) corresponds to a margin approaching but still under 100% (90% in that example).
Which one should I use for clothing retail pricing?
Markup is more common for setting prices from cost (multiply cost by a known markup factor); margin is more common for evaluating overall business profitability (what percentage of total revenue is actual profit). Both describe the same numbers — use whichever your business or accountant works in.
