Understanding Customer Lifetime Value
Why LTV Matters
LTV tells you how much revenue you can expect from a customer. This determines how much you can spend on acquisition, which products to invest in, and whether your business model is sustainable.
How to Increase LTV
Three levers control LTV: reducing churn (extend lifespan), increasing ARPU (upsells, price increases), and improving margins. Chargezen helps with all three through AI-powered retention and checkout optimization.
