Customer lifetime value
Customer lifetime value is an estimate of the economic value a customer contributes across the duration of the relationship, using observed or expected revenue and retention behaviour.
Customer lifetime value is a decision metric for the full customer relationship, not a score for a single purchase. It connects economic value to how long a customer remains active and how that behaviour changes over time.
RFM analysis provides one route into the measurement. Recency, frequency and monetary behaviour describe the customer's observed relationship with the programme, giving the value estimate a behavioural base instead of treating every customer as interchangeable.
Cohort analysis changes the question from “What is the average customer worth?” to “How does value develop for customers who entered at the same time or under the same conditions?” That distinction matters when acquisition periods, offers or programme rules change.
Churn rate supplies the retention signal. A lifetime value model that ignores churn can assign the same future to a customer who remains active and one who is already leaving. The rate does not explain the reason for departure, but it marks the point at which expected future value contracts.
The metric should also remain separate from revenue recognition. Customer lifetime value describes an economic relationship over time. Revenue recognition describes when revenue is recorded under the applicable accounting treatment. Using one as a substitute for the other turns a planning metric into an accounting claim.
A useful reading of the metric therefore keeps the customer view, the cohort view and the churn view visible together. RFM analysis describes the current pattern, cohort analysis shows how that pattern changes across groups, and churn rate constrains the future value assigned to the relationship.
If a customer generates 40 dollars of contribution each month and is expected to remain active for 10 months, the simple lifetime value estimate is 400 dollars. If a 20 percent retention adjustment is then applied to reflect expected churn, the adjusted estimate is 320 dollars, showing why the contribution amount and the expected duration have to be read together.
