What Is Gross Margin? A Complete Guide for Retailers
Gross margin is the single most-quoted profitability metric in retail. This guide explains the formula, benchmarks by category, and the practical levers that move it.
Calculate markup percentage from cost and selling price. Useful for pricing decisions and category planning.
Markup
50.00%
Profit per Unit
$50.00
Selling Price
$150.00
Cost
$100.00
Formula Used
((Selling Price − Cost) ÷ Cost) × 100
((Selling Price − Cost) ÷ Cost) × 100
Markup is the amount added to the cost of a product to determine its selling price, expressed as a percentage of cost.
A store buys a backpack for $40 and sells it for $60. Markup = ((60 − 40) ÷ 40) × 100 = 50%. So the markup over cost is 50%.
Markup is a percentage of cost. Margin is a percentage of selling price. A 50% markup equals roughly a 33% margin.
Not necessarily. Higher markup may reduce sales velocity. Balance markup against turnover.
Margin = Markup ÷ (1 + Markup). For example, a 50% markup = 0.5 / 1.5 = 33.33% margin.
