Profit Margin Calculator
Revenue in, cost in, margin out — plus the markup that produced it.
Method
How it works
Enter total revenue and the cost associated with producing it. The difference is gross profit, and dividing that profit by revenue gives the profit margin.
Markup uses cost as its base instead, while the cost ratio shows the share of revenue consumed by cost. This is why markup and margin are not interchangeable.
Common questions
Frequently asked questions
What is the difference between margin and markup?
Margin divides profit by revenue, while markup divides profit by cost.
Can profit margin be negative?
Yes. Margin is negative when cost is greater than revenue.
Should I enter gross or net revenue?
Enter the revenue figure that matches the margin you want to measure: gross revenue before returns and discounts for a gross sales view, or net revenue after those deductions for a net sales view. Keep the cost figure on the same basis.
