Markup (business) Markup is the ratio between the cost of a good or service and its selling price. It is expressed as a percentage over the cost.

The total cost reflects the total amount of both fixed and variable expenses to produce and distribute a product. Markup can be expressed as a fixed amount or as a percentage of the total cost or selling price. Retail markup is commonly calculated as the difference between wholesale price and retail price, as a percentage of wholesale. Other methods are also used.
