Frequently asked questions
How is markup calculated?
Markup is profit expressed as a percentage of the cost price: selling price = cost price × (1 + markup% ÷ 100).
What is the difference between markup and margin?
Markup is profit as a percentage of cost. Margin is profit as a percentage of selling price. A 40% markup is not the same as a 40% margin — this calculator shows both.
How do I convert a markup percentage to a margin percentage?
Margin % = markup ÷ (100 + markup) × 100. For example, a 40% markup equals roughly a 28.6% margin.
Is anything I type sent to a server?
No. Every calculation runs entirely in your browser — nothing is transmitted or logged.
