FAQ

Customer lifetime value questions answered

What's the difference between simple and predictive LTV?+
Simple LTV = ARPU × Gross Margin / Churn — uses averages. Predictive LTV uses early customer behavior to project future value. Both are useful: simple for quick benchmarks, predictive for identifying high-value segments.
What's a healthy LTV:CAC ratio?+
Target LTV:CAC > 3x. Below 3x means you're spending too much to acquire customers. Between 3x-5x is healthy. Above 5x means you may be under-investing in growth. SaaS investors look for >3x.
What's a good CAC payback period?+
Payback period = CAC / (Monthly ARPU × Gross Margin). Best-in-class SaaS: <12 months. Acceptable: 12-18 months. Concerning: >24 months. Longer payback strains cash flow and increases risk.
Should I include gross margin in LTV?+
Yes — absolutely. LTV without gross margin overstates customer value because it ignores COGS. Use gross margin for accurate profitability measurement. Our calculator includes it automatically.
How do I calculate LTV for non-subscription businesses?+
For ecommerce/retail: LTV = Average Order Value × Purchase Frequency × Average Customer Lifespan (in years) × Gross Margin. Our advanced mode supports this formula.
What's the difference between LTV and CLV?+
No difference — LTV (Lifetime Value) and CLV (Customer Lifetime Value) are the same metric. Different acronyms, same meaning.
How does churn affect LTV?+
Churn has an exponential impact on LTV. Reducing monthly churn from 5% to 3% doubles LTV. Our churn improvement simulator shows this dramatic effect.
What's the average LTV for SaaS companies?+
SMB SaaS: $5,000-25,000 LTV. Mid-market: $25,000-100,000. Enterprise: $100,000-500,000+. LTV varies by pricing, churn, and gross margin. Use our calculator with your numbers.
