Frequently asked questions
What's a good LTV:CAC ratio?
3:1 or better is the common benchmark; below 1:1 means you lose money on each customer. Much above 5:1 can mean you're under-investing in growth.
What's a good churn rate?
For SMB SaaS, 3–5% monthly is typical; enterprise SaaS aims for under 1% monthly (under 10% annually).
What's a good payback period?
Under 12 months is strong for SMB products; enterprise companies often accept 18–24 months.
