Quick answer
Margin is profit read as a slice of revenue. Subtract cost from revenue to get profit, then divide by revenue. Sell for $60 against a $40 cost and the $20 profit is 20 ÷ 60 = 33.33% margin. In plain terms, a third of every sale dollar is profit. Because the base is revenue and not cost, margin can never top 100%.

How it works

margin = (revenue − cost) ÷ revenue × 100profit = revenue − cost

profit as a percent of revenue

Margin is capped at 100%, since the most you can keep is all of the revenue when cost is zero. That is what separates it from markup, which sits on top of cost and can run past 100% with room to spare.

Subtract cost from revenue, divide by revenue, and multiply by 100.

No. Margin measures profit against revenue; markup measures it against cost. The same $20 profit is a 33% margin but a 50% markup.
