What is Average Customer Lifespan?

Average Customer Lifespan is the duration of time that a customer continues to do business with you before they churn or become inactive.

How do you calculate customer lifespan from churn?

The simplest way is: Lifespan = 1 / Churn Rate. For example, if your monthly churn is 5% (0.05), the average lifespan is 1 / 0.05 = 20 months.

Why does lifespan matter for LTV?

Customer Lifetime Value (LTV) is directly calculated as (Average Order Value x Purchase Frequency x Lifespan). Improving lifespan is the most powerful lever for increasing LTV.

How can I increase the average customer lifespan?

Focus on proactive customer success, personalized engagement flows, loyalty programs, and resolving product friction points that cause early-stage churn.
