Definition
The direct costs of producing the goods or services sold by a business, including raw materials and direct labor. It covers direct production or acquisition costs during a specific period.
The direct cost attributable to the production or acquisition of the goods sold or services delivered by a company during a specific period.
Why it matters
Understanding COGS is essential for setting profitable prices and determining gross margin. If your direct costs are too high, scaling up will only accelerate your losses. Tracking COGS helps you optimize production efficiency and negotiate better rates with suppliers.
