How to Calculate Profit Margin
Profit margin shows how much profit a business keeps from its revenue after costs are subtracted.
Profit margin formula
The basic formula is:
Profit = Revenue - Cost
Profit Margin = Profit / Revenue * 100 Worked example
If a business makes $10,000 in revenue and has $6,500 in cost, its profit is $3,500.
Divide $3,500 by $10,000, then multiply by 100. The profit margin is 35%.
Margin vs markup
Margin and markup use different denominators. Margin compares profit to revenue. Markup compares profit to cost. A 35% margin is not the same as a 35% markup. See markup vs margin for a detailed comparison.
