Gross Margin

Category: Metrics & KPIs · Level: Entry · Also called: Gross profit margin

TL;DR

The percentage of revenue remaining after subtracting cost of goods sold (COGS), reflecting the unit economics of delivering the product.

Gross margin is the revenue left over after the direct costs of delivering the product — hosting, customer support, payment processing, third-party services. It's the most fundamental unit-economics measure: low gross margin caps how much the company can spend on sales, marketing, R&D, and operations.

SaaS gross margin typically runs 70–85%; transactional businesses 30–60%; e-commerce and marketplaces vary widely depending on take rate. The trend matters as much as the level — gross margin should expand as the company scales.

Formula

Gross Margin = (Revenue − COGS) ÷ Revenue

  • Revenue — Net revenue in the period
  • COGS — Direct cost of delivering the product (hosting, support, processing)

Worked example

SaaS revenue $10M, COGS (hosting + customer support + payment processing) = $1.8M. Gross margin = ($10M − $1.8M) ÷ $10M = 82%. Marketplaces typically run 50–70%; pure SaaS 75–85%; managed services 30–50%.

Common pitfalls

  • Excluding important direct costs (support, infrastructure) from COGS.
  • Comparing gross margin across business models that don't compare.
  • Ignoring gross margin trend when it's quietly compressing.
