Markup income typically refers to the profit or revenue generated by adding a markup or margin to the cost of goods or services. In business and finance, "markup" is the amount added to the cost of producing or purchasing a product or service to determine its selling price. The markup is essentially the difference between the cost of production and the final selling price. The formula for calculating markup is: Markup = Selling Price − Cost Price Markup=Selling Price−Cost Price Markup is often expressed as a percentage of the cost price. The formula for calculating the markup percentage is: Markup Percentage = ( Markup Cost Price ) × 100 Markup Percentage=( Cost Price Markup )×100 So, markup income is the additional revenue or profit earned by a business through the application of a markup to its costs.
