What Is Cost of Goods Sold (COGS)?

The cost of goods sold is traditionally the costs of materials and production of the goods a business sells.

For a manufacturing company this is materials, labor, and factory overhead. For a retail shop it would be what it pays to buy the goods that it sells to its customers.

For service businesses, that don’t sell goods, the same concept is normally called “cost of sales,” which shouldn’t be confused with “sales and marketing expenses.” The cost of sales in this case is directly analogous to cost of goods sold. For a consulting company, for example, the cost of sales would be the compensation paid to the consultants plus costs of research, photocopying, and production of reports and presentations.

In standard accounting, costs of sales or costs of goods sold are subtracted from sales to calculate gross margin. These costs are distinguished from operating expenses, because gross profit is gross margin less operating expenses. Costs are not expenses.
