Margin vs. Markup
This calculator finds your profit, profit margin, and markup based on the cost of a product and the price you sell it for. Margin and markup are related but different: margin is profit as a percentage of selling price, while markup is profit as a percentage of cost.
The Formula
Profit = Selling Price – Cost. Margin = (Profit ÷ Selling Price) × 100. Markup = (Profit ÷ Cost) × 100.
