COGS

Full name: Cost of Goods Sold

Also known as: cost of sales, direct costs, cost of goods sold

Definition

The direct costs of producing the goods or services sold by a business, including raw materials and direct labor.

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.

Formula

COGS = Beginning Inventory + Purchases - Ending Inventory

Improvement tips

  • Negotiate bulk discounts with material suppliers to reduce unit costs.
  • Track direct labor hours carefully to ensure production time remains efficient.
  • Audit inventory regularly to identify and minimize material waste or shrinkage.

Common mistakes

  • Including indirect operating expenses like office rent or administrative salaries in COGS.
  • Failing to account for raw material price fluctuations when calculating product profitability.
  • Neglecting direct labor costs when calculating the COGS for service-based businesses.
