What Is a Good CAC for B2B SaaS?

Customer Acquisition Cost (CAC) measures the total spend required to win one new customer. In B2B SaaS, median CAC runs $300–600 for SMB and $1,000–5,000 for mid-market, depending on channel mix. The critical number isn't CAC in isolation — it's the LTV:CAC ratio, where 3:1 is the minimum acceptable and 5:1 is elite.

A common trap: teams benchmark CAC against industry averages rather than against their own LTV. A $2,000 CAC on a $40,000 ACV account is exceptional. The same CAC on a $3,000 ACV account is a structural problem. Context always wins over the absolute number.
