How the calculation works

Markup = (selling price − cost) / cost × 100

Markup describes the increase relative to original cost. A 50% markup on a $60 item produces a $90 price and a 33.33% margin. Confusing markup and margin can lead to underpricing. Include appropriate direct costs before using this tool to support a pricing decision.

A worked example

($100 − $60) ÷ $60 × 100 = 66.67% markup.

Reading your result

Use the main result together with its units and supporting figures. Display values are rounded; calculations keep their underlying precision. A change in inputs or assumptions can change the answer. Compare the step-by-step working with your intended use before relying on an estimate.

Frequently asked questions

What is a 100% markup?

A selling price twice the cost. That corresponds to a 50% gross margin.

Can cost be zero?

Not for this ratio: markup would divide by zero.
