How to Calculate Markup and Set a Selling Price

Use markup to turn cost into a selling price, then check the resulting dollar profit and margin.

Markup is the percentage added to cost to produce a selling price. It is useful when cost is the number you know first and you need a repeatable pricing rule.

Markup formula

markup % = (selling price − cost) ÷ cost × 100

Set a selling price from markup

selling price = cost × (1 + markup rate)

For a $50 cost with a 40% markup: 50 × 1.40 = $70.

The resulting margin is different

The $20 profit is 40% of the $50 cost, but only 28.57% of the $70 selling price. That is the margin.

Quick markup-to-margin examples

Markup Approx. margin
25% 20%
50% 33.33%
100% 50%
200% 66.67%

Build a useful cost figure first

If your input includes only the supplier price, the calculated profit may disappear after freight, packaging, labour, card fees, marketplace commissions, returns, or other direct costs. Decide whether your markup policy is based on landed cost, material cost, labour cost, or another clearly defined base.

Pricing is not only arithmetic

A formula can produce a mathematically consistent price, but the market still matters. Competitor pricing, perceived value, capacity, inventory turnover, and customer acquisition costs can all change the price a business can sustainably charge.
