Repeat Purchase Rate is closely related to Customer Loyalty and Customer Retention Rate. Customer loyalty indicates the likelihood of customers returning to make repeat purchases, and a high Repeat Purchase Rate reflects strong customer loyalty. The Customer Retention Rate measures the percentage of customers a company retains over a period, which directly impacts the Repeat Purchase Rate.

Customer Lifetime Value (CLV) estimates the total revenue a business can expect from a single customer over their entire relationship. A higher Repeat Purchase Rate increases the CLV as customers make more frequent purchases. On the other hand, Customer Acquisition Cost (CAC) is the expense incurred to acquire a new customer. A higher Repeat Purchase Rate can lower the CAC over time since retaining existing customers is generally more cost-effective than acquiring new ones.

Customer Satisfaction (CSAT) and Customer Engagement are vital for a high Repeat Purchase Rate. Satisfied and engaged customers are more likely to return and make repeat purchases. Net Promoter Score (NPS) is another relevant metric, indicating the likelihood of customers recommending the business to others, which can indirectly boost the Repeat Purchase Rate.

Purchase Frequency measures how often customers make purchases within a given period, which is a direct contributor to the Repeat Purchase Rate. Average Order Value (AOV) represents the average amount spent each time a customer places an order. While AOV focuses on the value of each transaction, increasing the Purchase Frequency can enhance the Repeat Purchase Rate and overall revenue.

Churn Rate measures the percentage of customers who stop doing business with a company over a given period. A high Churn Rate negatively impacts the Repeat Purchase Rate, as it indicates customers are not returning for repeat purchases. Reducing the Churn Rate is essential for improving the Repeat Purchase Rate and sustaining business growth.
