From Wikipedia, the free encyclopedia. Gross margin is the difference between revenue and cost of goods sold, or COGS, divided by revenue, expressed as a percentage. Generally, it is calculated as the selling price of an item, less the cost of goods sold (production or acquisition costs, essentially). Gross Margin is often used interchangeably with Gross Profit, but the terms are different.
