Gross profit isolates the efficiency of production and pricing. Cost of goods sold (COGS) includes raw materials, direct labour and manufacturing overhead — but excludes sales, marketing, R&D, rent and admin.
Gross margin (gross profit ÷ revenue) is the comparable metric across firms and industries. Software businesses typically run 70–90% gross margin; supermarkets 20–30%; commodity manufacturers 5–15%. A falling gross margin warns of pricing pressure or rising input costs.
Gross Profit = Revenue − Cost of Goods Sold
A bakery sells CHF 500,000 of bread per year and pays CHF 200,000 in flour, yeast and baker wages — gross profit is CHF 300,000, a 60% gross margin.
