Cost of goods sold
The direct cost of producing the goods or services you actually sold — subtracted from revenue to get gross profit. What belongs in COGS, and what doesn’t, decides whether your margin is real.
In plain terms
What cost of goods sold means.
Cost of goods sold (COGS) is the direct cost of producing the goods or delivering the services a business sold during a period — materials, direct labor, and other costs tied directly to the sale. It is subtracted from revenue to calculate gross profit, the first real profitability line on the P&L.
The defining test is “direct”: a cost belongs in COGS if it rises and falls with what you sell. Rent, software, and admin salaries are operating expenses, not COGS, because you’d pay them whether or not you made a sale.
Miscategorized COGS hides your margin.
Gross margin (gross profit ÷ revenue) is one of the most important numbers a business watches — and it’s only meaningful if COGS is drawn in the right place consistently. Lumping operating expenses into COGS, or scattering true direct costs into overhead, makes the margin look better or worse than it is and breaks period-to-period comparison.
Getting the COGS line right — and consistent — is a frequent cleanup correction and depends on a chart of accounts built for how the business actually earns.
