Calculate the selling price and profit margin based on cost and markup percentage.
Markup is the percentage added to cost to get the selling price. Margin is the percentage of the selling price that is profit. A 50% markup equals a 33.3% margin.
Markup% = Margin% / (100 − Margin%) × 100. For example, a 25% margin equals a 33.3% markup.
It varies by industry. Grocery stores typically use 25-50% markup, clothing 50-100%, jewelry 100-300%, and restaurants 200-400% on food items.
