Calculate selling price, markup percentage, and profit margin
Markup and margin are both ways to express profit, but they use different bases. Markup is the percentage added to your cost price. Margin is the percentage of the selling price that is profit. A 50% markup results in a 33.3% margin. A 100% markup results in a 50% margin.
Selling Price = Cost × (1 + Markup/100). Profit Margin = (Selling Price - Cost) ÷ Selling Price × 100.
