Margin and markup both compare price with cost, but they answer different questions. Confusing them can lead to a selling price that is materially lower than intended.
Gross margin uses selling price as the denominator
If a product costs $60 and sells for $100, gross profit is $40. Gross margin is $40 divided by the $100 selling price, or 40%.
Markup uses cost as the denominator
Using the same example, markup is the $40 gross profit divided by the $60 cost. That equals about 66.67%. The profit dollars are identical; only the denominator changes.
Use the formulas side by side
- Gross profit = price − cost.
- Gross margin % = gross profit ÷ price × 100.
- Markup % = gross profit ÷ cost × 100.
The Profit Margin Calculator computes all three from the same inputs so the distinction stays visible.
Convert a target margin into a selling price
To reach a target gross margin, divide cost by one minus the target margin rate. With a $60 cost and a 40% target margin, price = 60 ÷ 0.60 = $100.
Why a 40% markup does not create a 40% margin
A 40% markup on a $60 cost produces an $84 price. Gross profit is $24, and margin is $24 ÷ $84, or about 28.57%. That gap is why teams should label spreadsheets and dashboards explicitly.
Gross margin is not net margin
Gross margin does not automatically include operating payroll, rent, software, marketing, taxes, financing, returns or every delivery cost. Define what is included in “cost” before using the figure for decisions.
Choose the metric that matches the decision
Markup is intuitive when pricing starts from cost. Margin is often more useful when comparing gross profitability as a share of revenue. The important thing is to state which one you are using and keep the definition consistent.

Additional finance context
Keep your pricing model explicit about cost, gross profit and margin. The clean claim rate guide is a useful example of why business metrics should define their numerator and denominator before teams compare results.
