What is customer lifetime value (CLV) and why does it matter in marketing budgeting?

• A. CLV is the net profit expected from a customer over the relationship; it guides acquisition spend and retention investments.
• B. CLV is the yearly revenue from a customer.
• C. CLV is the number of customers acquired in a campaign.
• D. CLV is the product's list price.

Answer: (A)

Customer lifetime value is the net profit you expect to earn from a single customer over the entire time they do business with you. It combines revenue, margins, how long the relationship lasts, and the costs involved in serving that customer. This matters for marketing budgeting because it tells you how much you can safely spend to acquire a customer and how much to invest to retain them in order to maximize long-term profitability. When CLV is higher than the cost to acquire (CAC), you can justify stronger, long-term marketing efforts and compare channels by the value they generate over time, not just immediate sales. In short, CLV guides how to allocate budget toward activities that increase enduring value rather than focusing only on short-term gains. By comparison, yearly revenue, the number of customers acquired, or the product’s price alone don’t capture how valuable a customer is across the entire relationship.
