Metrics
Gross Margin
Quick definition
Revenue minus cost of goods sold, as a percentage; the share of revenue left after the direct cost to deliver the product.
Gross margin is revenue minus cost of goods sold (COGS), expressed as a percentage of revenue. It shows how much of each dollar is left after the direct cost of delivering the product, before sales, marketing, R&D, and G&A. Software gross margins are typically high (best-in-class SaaS runs 75-85 percent), but AI-native products that pass through model or inference costs can run much lower, which changes LTV, the Rule of 40, and how much a company can afford to spend to grow. Gross margin is one of the first numbers an investor checks, so get COGS classification right.
