Customer Lifetime Value in Practice

Simple CLV Calculation

CLV = Average order value × Number of purchases per year × Average customer lifespan

Example: A customer spends $70 on average, 4 times per year, and remains a customer for 5 years: CLV = $70 × 4 × 5 = $1,400

CLV and Churn

Average customer lifespan = 1 / Churn rate

Example: Monthly churn = 5% → Average customer lifespan = 1 / 0.05 = 20 months

Segmented CLV

One of the most important applications of CLV is segmentation: Which customer segments have the highest CLV? What characterizes them? And which touchpoints and experiences drive retention for those specific segments?

Typically, companies find that 20% of customers generate 80% of CLV. Therefore, identifying and prioritising these high-CLV segments is one of the most effective strategic exercises. Additionally, use NPS data segmented by customer value to understand what drives retention of your most important customers.

CLV and Customer Experience

Customer experience drives CLV through three mechanisms:

1. Retention: Good experiences reduce churn and extend customer lifespan
2. Increased spending: Satisfied customers buy more and more often (upsell/cross-sell)
3. Advocacy: Promoters recommend the company, which lowers CAC for newly acquired customers

NPS programs with close the loop can be directly credited with CLV improvement when Detractors are saved from churn and reactivated as neutral or positive customers.
