Profit Margin Calculator
Calculate gross profit, net profit and markup from cost and selling price. Works in reverse to find the required selling price for a target margin.
How to use
Margin vs markup — what's the difference?
Profit margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. A 50% markup on a £50 item gives a £75 selling price (£25 profit), which is actually a 33.3% margin — not 50%. The tool shows both clearly.
