CLV anchors economic decisions about acquisition spend, retention investment, and segment prioritization. The simplest version multiplies average revenue per user by gross margin and average lifespan; more sophisticated versions discount future cash flows and incorporate churn probability. CLV is highly sensitive to churn assumptions — a 1-point monthly churn change can swing CLV 20%+. Healthy SaaS businesses target a CLV:CAC ratio of 3:1 or better. CLV correlates strongly with NPS in long-cycle businesses: Bain research finds promoters have 2.5×-5× the lifetime value of detractors in subscription categories. ## Formula `CLV = (Average Revenue × Gross Margin) / Monthly Churn Rate` ## Example A SaaS with $80/mo ARPU, 80% gross margin, and 2.5% monthly churn: CLV = (80 × 0.80) / 0.025 = $2,560. If CAC is $640, CLV:CAC = 4:1. ### Run a Customer Lifetime Value (CLV / LTV) survey free SpaceForms includes pre-built templates with validated wording.
