LTV (Lifetime Value)
Lifetime Value is the predicted total revenue a business can expect from a single customer account throughout the entire duration of their relationship. It helps businesses determine how much they can afford to invest in acquiring and retaining customers. A customer who subscribes for three years generates far more value than one who churns after a month, and LTV captures this difference quantitatively.
The simplest LTV calculation multiplies average revenue per customer by average customer lifespan. More sophisticated models factor in gross margin, expansion revenue from upsells, and discount rates to arrive at a net present value. For subscription businesses, LTV often correlates directly with churn rate: lower churn means longer customer lifespans and higher lifetime value.
For web development and digital product teams, LTV has practical implications. The ratio of LTV to customer acquisition cost determines whether a business model is sustainable. An LTV-to-CAC ratio below three typically signals that acquisition spending is too high or retention is too low. This metric drives decisions about feature investment, onboarding optimization, and whether to allocate engineering resources toward reducing churn rather than acquiring new users.
