How it is calculated
Gross profit = revenue − cost of goods sold (COGS). Gross margin = gross profit ÷ revenue × 100% — the share of every dollar of revenue left after the direct cost of producing or buying what you sold.
COGS covers direct costs only: materials, raw goods, components, piece-rate wages of production staff. Office rent, marketing, accounting salaries and other overhead aren't part of COGS — they get subtracted later, on the way from gross profit to operating and net profit.
Gross margin shows whether a business even has room to cover overhead and turn a profit — if it's low or negative, no amount of cutting rent or ad spend will fix it: the problem is in pricing or direct product cost.
