Gross margin = (revenue − COGS) ÷ revenue. Don't confuse it with markup, which is profit ÷ COGS — markup is always higher than margin.

About this tool

Margin vs markup — they are not the same

Margin = profit / revenue. Markup = profit / cost. A 40% markup is a ~28.6% margin. Confusing the two is the most common pricing mistake in small businesses.
