Customer Lifetime Value (LTV)

Customer lifetime value represents the total economic value of a customer relationship. For a subscription business, this depends on the monthly revenue per customer and how long they stay. For a retail business, it depends on average order value, purchase frequency, and customer lifespan. LTV is the ceiling for how much you can profitably spend to acquire and retain a customer.

LTV is not just a financial metric; it is a strategic guide. A high LTV justifies investing heavily in customer experience, support, and retention. It supports premium acquisition channels that lower-LTV competitors cannot afford. It also shifts focus from transactional revenue to relationship-building, because a 10% improvement in retention can increase LTV by 30-50%.

Calculating LTV accurately requires honest inputs. The most common mistake is using theoretical or optimistic retention rates instead of actual data. Another mistake is ignoring variable costs and calculating LTV on revenue rather than gross profit. The most useful LTV calculation uses gross profit per customer and empirically measured retention rates, not wishful projections.
