Divide net profit by revenue to get the margin that survives every cost, tax and interest charge.
Margin divides profit by revenue; markup divides the same profit by cost. They are routinely confused, so both are shown — a 50% margin is a 100% markup. Margin is what funds every fixed cost in a business business, and mispricing by a few points is the difference between scaling profitably and scaling losses.
