What is customer lifetime value?
Customer lifetime value is a prediction of the net profit attributed to the entire future relationship with a customer. It answers a deceptively simple question: how much is a customer worth to your business, not just on their first purchase, but across every transaction over months or years?
The basic formula is straightforward: average purchase value multiplied by average purchase frequency multiplied by average customer lifespan. But the real power of CLV lies in how you use it. When you know the lifetime value of a customer, you can make smarter decisions about how much to spend acquiring them, which segments to prioritize, and where to invest in retention.
CLV reframes your entire marketing strategy. Instead of optimizing for the cheapest acquisition cost, you optimize for the most profitable long-term relationships. A customer who costs more to acquire but stays for three years and refers others is far more valuable than a bargain-bin lead who churns after one month.
