What Markup Is and Why Calculating It Correctly Matters
Markup is the percentage added to a product's cost to arrive at its selling price. It sounds simple, but calculating markup incorrectly — or confusing it with profit margin — is one of the costliest mistakes any business can make.
Imagine you sell 500 products a month and use a 30% markup, thinking your margin is 30%. In practice, the real margin is only 23.08%. With an average cost of $50, you're losing $3.46 per product — which adds up to $1,730 per month simply vanishing from your profit.
The Two Markup Formulas
Simple Markup
Calculates the difference between the selling price and the cost, divided by the cost:
Example — Apparel product
T-shirt bought for $22.00, sold for $59.90.
- Profit = $59.90 − $22.00 = $37.90
- Markup = ($37.90 ÷ $22.00) × 100 = 172.3%
- Margin = $37.90 ÷ $59.90 × 100 = 63.3%
Divisor Markup (professional method)
Incorporates all variable expense percentages and margin into the calculation:
Selling Price = Cost ÷ Divisor
Example — Sale with marketplace fees
Product with a cost of $35.00. Expenses: 13% commission + 3% payment gateway + 6% tax + 20% desired margin = 42%.
- Divisor = 1 − 0.42 = 0.58
- Selling Price = $35.00 ÷ 0.58 = $60.34
- Equivalent simple markup: (60.34 − 35.00) ÷ 35.00 × 100 = 72.4%
Calculating Markup for Different Industries
Food Retail
Typical markup between 30% and 80%. Perishables require higher markups to cover losses from spoilage.
Restaurant
A food cost of 25% to 35% implies a markup of 185% to 300% on ingredients.
Apparel
Markups of 100% to 300% are common to cover seasonality and unsold inventory.
E-commerce
Include all fees in the divisor. Simple markup alone is misleading — use the divisor markup method.
Converting Markup to Margin and Vice Versa
Markup → Margin
Margin = Markup ÷ (1 + Markup)
Margin → Markup
Markup = Margin ÷ (1 − Margin)
