LTV
Customer Lifetime Value
The total revenue expected from a customer over their entire relationship with the business. The LTV:CAC ratio is a core health metric; a ratio above 3:1 generally indicates a sustainable growth model for subscription businesses.
How LTV works in practice
LTV = Average Revenue Per User (ARPU) × Gross Margin % ÷ Monthly Churn Rate. For a SaaS product with £100 ARPU, 70% gross margin, and 3% monthly churn, LTV = £100 × 0.7 ÷ 0.03 = £2,333. Improving gross margin by 5% or reducing monthly churn by 1 percentage point each increases LTV by 15–30%, making retention and margin optimisation high-leverage LTV improvement strategies that also create more CAC headroom. LTV predictions made at the point of acquisition, before long-run retention data exists, must be based on early engagement signals (activation rate, D7 retention, product usage frequency) correlated with LTV in historical cohorts rather than extrapolating from limited early data.
