Gross Margin

What it measures

How much of each revenue dollar survives the cost of actually serving customers. For SaaS, COGS is the direct cost of running the service—hosting and infrastructure, customer support, and payment-processing fees—not sales, marketing, or R&D. Gross margin sets the ceiling on every downstream margin and unit-economics metric: LTV, CAC payback, and the Rule of 40 all degrade when it is low, because there is simply less of each dollar to work with. It is the structural reason software is a high-multiple business—once built, each additional customer is cheap to serve.

Benchmarks

• Software SaaS commonly runs ~70–80%+; the median total gross margin for private SaaS was ~71% in the 2024 KeyBanc survey, and subscription-only margin sat near 79% (KeyBanc 2024 / ICONIQ 2025).
• Self-serve / PLG models reach roughly 80–85% (lighter COGS: hosting, payment processing, automated support).
• Enterprise / high-touch models run roughly 70–75% (heavier COGS: implementation, professional services, DevOps).
• AI-native products often sit lower (~50–60%) because GPU compute and model-inference costs land in COGS.

What to watch

• Rising: Usually infrastructure efficiency (better cloud utilization, cheaper egress) or a mix shift toward higher-margin self-serve revenue. Confirm it’s structural and not a one-time credit—reserved-instance discounts and vendor credits flatter a quarter without changing the underlying cost curve.
• Falling: Watch for COGS creeping in where it doesn’t belong—heavy professional-services revenue, generous support staffing, or inference costs on an AI feature can drag blended margin down. Segment subscription margin from services margin; a healthy software margin can be masked by a low-margin services line bundled into the total.

In practice

A SaaS company reported a blended 62% gross margin and assumed its software economics were weak. Splitting the line revealed subscription margin was a healthy 81%, dragged down by a break-even professional-services arm sold to win enterprise logos. The product itself was fine; the services were a customer-acquisition cost masquerading as low-margin revenue. Reporting the two separately changed how the board read the business and stopped a misguided push to cut hosting spend that wasn’t the problem.
