Customer Lifetime Value

In marketing, customer lifetime value (CLV), lifetime customer value (LCV), or lifetime value (LTV) is the net present value of the cash flows attributed to the relationship with a customer. The use of customer lifetime value as a marketing metric tends to place greater emphasis on customer service and long-term customer satisfaction, rather than on maximizing short-term sales. One of the first accounts of it is in the 1988 book Database Marketing, and includes detailed worked examples.[1][2]

Customer lifetime value has intuitive appeal as a marketing concept, because in theory it represents exactly how much each customer is worth in monetary terms, and therefore exactly how much a marketing department should be willing to spend to acquire each customer. In reality, it is difficult to make accurate calculations of customer lifetime value. The specific calculation depends on the nature of the customer relationship. Customer relationships are often divided into two categories. In contractual or retention situations, customers who do not renew are considered "lost for good". Magazine subscriptions and car insurance are examples of customer retention situations. The other category is referred to as customer migration situations. In customer migration situations, a customer who does not buy (in a given period or from a given catalog) is still considered a customer of the firm because she may very well buy at some point in the future. In customer retention situations, the firm knows when the relationship is over. One of the challenges for firms in customer migration situations is that the firm may not know when the relationship is over (as far as the customer is concerned).[3]
