Profit Margin and Markup Formulas
Profit Margin % is calculated as ((Selling Price minus Cost Price) divided by Selling Price) x 100, expressing profit as a share of revenue, while Markup % is calculated as ((Selling Price minus Cost Price) divided by Cost Price) x 100, expressing profit as a share of cost. Because the denominators differ, Markup % is always numerically higher than Margin % for the same rupee profit, and the two can be converted using Margin % = Markup % / (1 + Markup %).
