SaaS Gross Margin measures profitability after COGS (Cost of Goods Sold) — hosting, support, third-party software, implementation. World-class SaaS achieves 80%+. The 'Rule of 40' uses gross margin × growth as a key metric for SaaS health.

SaaS COGS Composition

Hosting (AWS/Azure/GCP): 30-40% of COGS. Customer support: 25-35%. Third-party software (Twilio, Stripe): 10-15%. Implementation/onboarding: 10-20%. Total COGS should be 20-30% of revenue for healthy SaaS.

Margin Compression Triggers

AWS bills growing faster than revenue: optimize architecture. Support tickets/dollar high: invest in self-serve. Implementation cost: standardize, automate. Third-party costs: re-negotiate at scale.

Margin → Valuation

Public SaaS multiples correlate with gross margin: 80% margin = 8-12x revenue. 70% = 5-8x. 60% = 3-5x. PE/VC discounts low-margin SaaS heavily. Invest in margin improvement for valuation lift.
