Customer Lifetime Value (CLTV or LTV)
What is customer lifetime value?
Customer lifetime value (LTV, also CLV or CLTV) is the total revenue a business can expect from a single customer over the entire duration of their relationship. LTV accounts for purchase frequency, average order value, and customer retention, giving marketers a forward-looking measure of how valuable a new customer will be — not just at the moment of acquisition, but across their full relationship with the brand.
How does customer lifetime value work?
Measuring customer lifetime value involves assessing how much a customer spends on average in each purchase, the average number of purchases they make within a period (average purchase frequency), and how long they typically stay as a customer (average customer lifespan).
Types of customer lifetime value:
- Actual CLTV: This is the actual amount of money a customer spends with a business over their lifetime.
- Predicted CLTV: This is an estimate of the amount of money a customer is expected to spend with a business over their lifetime.
How to measure customer lifetime value: Calculating the average amount of money a customer spends on each purchase can be complex. The average purchase frequency is the average number of purchases a customer makes in a given period of time. The average customer lifespan is the average amount of time a customer remains a customer of the business.
Why is customer lifetime value important to marketers? CLTV provides insight into the profitability of customer relationships and is a key aspect to a brand’s retention efforts as well as their pricing strategies.

LTV and commerce media
Commerce media advertising optimized for LTV — rather than just first-purchase conversion — attracts customers who are more likely to return, spend more, and remain loyal. Post-transaction environments, which reach consumers at moments of active engagement, tend to attract higher-LTV customers because the placement context selects for consumers who are already demonstrating transactional intent.
In the Fluent context
Fluent's advertiser platform is optimized for downstream LTV, correlating campaign performance with purchase history, income signals, and loyalty patterns — not just first-touch conversion rates.
