Customer LTV is calculated by dividing Average Revenue Per User (ARPU) by churn rate, or using more complex formulas that factor in gross margins and growth rates.
Customer Lifetime Value (LTV) represents the total revenue a SaaS business can expect from a single customer throughout their subscription lifecycle. Accurate LTV calculation is crucial for determining appropriate customer acquisition spending and business valuation.
Basic LTV Formula: LTV = ARPU ÷ Churn Rate
For example, if ARPU is $100/month and monthly churn is 5%, then LTV = $100 ÷ 0.05 = $2,000
Advanced LTV Formula: LTV = (ARPU × Gross Margin %) ÷ Churn Rate
This accounts for the actual profit contribution rather than just revenue.
Cohort-Based LTV: For more accuracy, calculate LTV by analyzing actual customer cohorts over time, considering:
Key Considerations:
The LTV:CAC ratio should ideally be 3:1 or higher, indicating healthy unit economics. Lower ratios suggest acquisition costs are too high or retention needs improvement.
Joni Van Langenhoven recommends using cohort-based analysis for the most accurate LTV calculations when presenting to investors.
