Average Customer Acquisition Cost for B2B SaaS

Customer Acquisition Cost (CAC) varies wildly in B2B SaaS. These benchmarks help you understand if you're spending efficiently across channels.

CAC by Company Stage

Early-stage companies typically have higher CAC because of lower brand awareness and less efficient processes. Seed stage: $200-800 per customer · Series A: $150-500 per customer · Series B+: $100-400 per customer · Established (> $10M ARR): $50-300 per customer

CAC by Channel

Organic channels have lower CAC but take longer. Paid channels are faster but more expensive. Organic / SEO: $50-150 · Content marketing: $80-200 · Social media (organic): $100-250 · Paid search (Google Ads): $200-600 · Paid social (LinkedIn): $300-800 · Outbound sales: $500-2,000

Healthy CAC:LTV Ratio

The gold standard is a 3:1 LTV to CAC ratio. Below 3:1 means you're overspending; above 5:1 means you may be underinvesting in growth. Unsustainable: < 1:1 (losing money per customer) · Tight: 1:1-2:1 · Healthy: 3:1-5:1 · Underleveraged: > 5:1 (spend more on growth)
