SaaS CAC Benchmarks by Go-to-Market Motion
CAC varies by an order of magnitude across go-to-market motions. PLG companies acquire customers at a fraction of SLG costs — median CAC for PLG freemium is under $500 — but monetize a smaller percentage of users. Enterprise field sales CAC routinely exceeds $50,000 when fully loaded with marketing overhead, quota-carrying salaries, and sales engineering time. The efficiency ratio (CAC payback period) is the more actionable metric — world-class PLG companies recoup CAC in under 6 months, while enterprise deals often run 18–24 months. The hybrid PLG-plus-sales motion that OpenView calls 'Product-Led Sales' is showing the best CAC efficiency at scale, with CAC payback periods 30–40% shorter than pure SLG.
| Metric | Value | Source | Year | Context |
|---|---|---|---|---|
| Median CAC — PLG / Self-ServeVC-backed | $300–$500 | OpenView Partners PLG Index 2024 | 2024 | PLG CAC looks low because product does the selling; the hidden cost is R&D investment in activation and onboarding that isn't captured in sales & marketing. |
| Median CAC — Inside Sales (SMB)SMB | $1,800–$3,500 | Pacific Crest SaaS Survey 2024 | 2024 | Inside sales at SMB ACV typically needs 2–4x ACV in CAC to remain viable — any higher and payback periods exceed 18 months. |
| Median CAC — Inside Sales (Mid-Market)Mid-Market | $6,000–$12,000 | Pacific Crest SaaS Survey 2024 | 2024 | Mid-market inside sales CAC is justified by higher ACV and lower churn, making payback periods comparable to SMB despite the larger upfront cost. |
| Median CAC — Field Sales (Enterprise)Enterprise | $35,000–$65,000 | KeyBanc Capital Markets SaaS Survey 2024 | 2024 | Enterprise CAC is only defensible with ACV above $80K and multi-year contract structures that secure 3+ year customer relationships. |
| Median CAC — Channel / Partner | $2,000–$5,000 | SaaStr Annual Benchmarks 2024 | 2024 | Channel-sourced CAC is lower but revenue sharing (typically 15–25%) reduces gross margins, so net CAC efficiency must be evaluated holistically. |
| CAC:LTV Ratio Benchmark (healthy) | 1:3 or better | Pacific Crest SaaS Survey 2024 | 2024 | A 1:3 LTV:CAC ratio is the floor for sustainable economics; best-in-class SaaS companies sustain 1:5 to 1:8 ratios at maturity. |
| PLG-plus-Sales CAC vs Pure SLG | 30–40% lower | OpenView Partners PLG Index 2024 | 2024 | The hybrid motion wins on CAC efficiency because product-qualified leads close faster with less sales overhead than cold outbound. |
