What is LTV (Lifetime Value)?
Lifetime Value (LTV), also called Customer Lifetime Value (CLV), measures the total net revenue or profit a business expects to generate from a customer across their entire relationship—from first purchase until they stop buying.
Instead of focusing on a single sale, LTV evaluates long-term value. Customers who repeatedly buy over months or years usually generate far more profit than their first transaction suggests.
Why does LTV matter?
- Helps decide how much you can spend on customer acquisition (CAC)
- Improves retention strategy and reduces churn
- Guides pricing, upselling, and cross-selling
- Ensures sustainable unit economics
- Increases company valuation and investor confidence
- Supports predictable long-term growth
How does LTV work?
- Measure average revenue per customer
- Estimate customer lifespan or tenure
- Include gross margins (not just revenue)
- Factor in churn rate
- Calculate expected lifetime value
- Compare with Customer Acquisition Cost (CAC)
- Optimize retention and spending strategies
Common LTV Formulas
- Basic: Avg Revenue × Customer Lifespan
- SaaS: (ARPU × Gross Margin) ÷ Churn Rate
- LTV/CAC Ratio: Lifetime Value ÷ Acquisition Cost
Healthy businesses typically target an LTV/CAC ratio of 3:1 or higher.
