Profit Margin Calculator
Enter your selling price and your cost. The calculator shows your profit, your profit margin as a percentage of the price, and the markup as a percentage of the cost.
Enter a revenue and cost above to see your profit, margin, and markup.
Margin vs markup
Margin and markup measure the same profit from two angles. Margin is profit as a share of the price you charge. Markup is profit as a share of what the item cost you. A $40 profit on a $100 sale is a 40% margin and a 66.7% markup.
This calculator shows both at once, so you can price from either direction. Need to price up from a known cost instead? Use the Markup Calculator.
