Customer lifetime value (LTV or CLV) is the money an average customer brings in from first purchase to last: every order, renewal, and upsell, minus refunds. One conversion is a snapshot. LTV is the movie.
It is the pair of churn: if people leave fast, LTV collapses even when ads look cheap. Track it in a CRM and analytics as a KPI next to ROI — acquisition only pays if LTV is higher than what you spent to win them. SaaS counts months of subscription; a shop counts years of baskets. A loyalty program exists to grow this number, not to give away free coffee for sport.
A real-life example of customer lifetime value
A Decatur coffee shop’s “regular” spends $8 a visit, twice a week, for three years. That is thousands of dollars — not the $8 ticket. If they churn after a month of burnt espresso and silence, you just paid Facebook for a tourist. The CRM should show that math, not only last week’s sales.
