Understanding how customer-related metrics impact business decisions is crucial for optimizing profitability and growth. For instance, knowing a customer's lifetime value (CLV) helps a company decide how much to invest in customer loyalty programs. A coffee shop chain, for example, might offer a rewards program to encourage frequent visits, knowing that loyal customers are more valuable over time.

Retention and churn rates provide insights into customer satisfaction and loyalty. For example, an online education platform that notices many students renewing their subscriptions for advanced courses can conclude that its content meets learners' needs. On the other hand, if a meal delivery service sees customers leaving after their first few orders, it might need to improve the variety or quality of its meals to keep customers returning.

When calculating customer profit, it's essential to consider all associated costs, including marketing, support, and delivery. For instance, a clothing brand might discover that while a particular line of products is famous, the high cost of returns and exchanges reduces overall profitability. To address this, the brand could improve its sizing guide or product descriptions to decrease return rates, ensuring customer interactions are more profitable.
