Markup & Margin Calculator

Markup is the percentage added to cost to get the selling price, calculated as (profit / cost) x 100. Margin is the percentage of the selling price that is profit, calculated as (profit / selling price) x 100. A 50% markup equals a 33.3% margin.

Markup percentage is calculated by dividing the profit (selling price minus cost) by the cost, then multiplying by 100. For example, if an item costs $40 and sells for $60, the markup is ($20 / $40) x 100 = 50%.

Profit margins vary widely by industry. Retail typically sees 2-5% net margins, while software companies may achieve 20-40%. A healthy gross margin depends on your overhead costs, competition, and market positioning.
