THE HOWThe formula
Margin = (revenue − cost) ÷ revenue × 100
A practical example
Revenue of $100 minus cost of $60 gives $40 profit and a 40% margin. Markup is 66.67%.
What to keep in mind
Revenue must be positive and cost cannot be negative. Losses produce a negative margin. Markup is undefined when cost is zero.
