What encompasses the total revenue from a client over the relationship with a business?

Customer lifetime value is a key metric that represents the total revenue a business can expect from a single client throughout their entire relationship. This calculation considers factors such as the average purchase value, purchase frequency, and the duration of the customer's engagement with the business. Understanding customer lifetime value helps businesses strategize around customer acquisition and retention, ensuring they invest appropriately to maximize long-term profitability.

The other options focus on different aspects of business performance. Profit margin pertains to the percentage of revenue that exceeds costs, reflecting overall profitability rather than client-specific revenue. Customer retention rate measures the percentage of clients a business retains over a specific period, providing insights into customer loyalty but not quantifying revenue. Market share represents the portion of a market controlled by a business compared to competitors, which does not account for individual client revenue contributions.
