CAC benchmarks by industry

  • B2B SaaS: Healthy CAC payback under 12 months; LTV:CAC ratio 3:1 or better.
  • E-commerce: Healthy CAC under 30% of first-year LTV.
  • Professional services: CAC under 15% of first-year revenue per client.
  • Marketplaces: Two-sided CAC requires separate calculation per side.

How to lower CAC

  1. Replace platform-reported attribution with marketing mix modeling and incrementality testing.
  2. Reallocate budget from low-incremental channels (typically branded search, retargeting) to upper-funnel.
  3. Improve activation and onboarding to convert more trial signups to paid.
  4. Build content and SEO infrastructure for organic acquisition (lower CAC over time).
  5. Implement product-led growth loops for compounding acquisition.
