How it's calculated
margin % = (price − cost) ÷ price × 100, markup % = (price − cost) ÷ cost × 100
price = selling price, cost = unit cost; profit = price − cost. Margin is profit over price, markup is profit over cost.
Common questions
What is the difference between margin and markup?
Margin is profit as a percent of the selling price. Markup is profit as a percent of the cost. A 50 percent markup is only a 33 percent margin.
How do I get the selling price from cost and margin?
Divide cost by (1 minus the margin as a decimal). A 40 dollar cost at a 20 percent margin sells for 50 dollars.
