Repeat Purchase Rate
Repeat purchase rate is the percentage of customers who make more than one purchase from a store within a defined time period, calculated by dividing the number of returning customers by total customers.
Understanding Repeat Purchase Rate
If your store had 1,000 unique customers in a quarter and 250 of them made at least two purchases, your repeat purchase rate is 25%. This metric is a fundamental indicator of customer loyalty and product-market fit. A high repeat purchase rate means customers are satisfied enough to come back, which is far more profitable than constantly acquiring new ones.
The economics are compelling. Acquiring a new customer costs five to seven times more than retaining an existing one, and returning customers tend to spend more per order because they already trust your brand. For consumable products like skincare, supplements, or coffee, repeat purchase rates above 40% are common and expected. For durable goods like furniture or electronics, lower rates are normal.
Several factors drive repeat purchase rate: product quality and satisfaction, post-purchase communication (email flows, loyalty programs), the breadth of your catalog (more products give reasons to return), and overall shopping experience. Stores that follow up after first purchase with personalized recommendations and timely replenishment reminders see measurably higher repeat rates.
Tracking repeat purchase rate over time reveals whether your retention strategies are working. A declining rate despite growing customer counts means you are acquiring less loyal customers or your product experience is degrading. Segmenting by acquisition channel shows which traffic sources bring customers who stick around.
Why It Matters for E-Commerce
Repeat purchase rate is one of the strongest predictors of long-term e-commerce profitability. Businesses with high repeat rates can afford higher customer acquisition costs because each customer generates more lifetime revenue, creating a sustainable competitive advantage that compounds over time.

Customer lifetime value (CLV) is the total net revenue a business can expect from a single customer account throughout their entire relationship. It accounts for repeat purchases, average order value, and the duration of the customer relationship.
Customer retention rate is the percentage of customers who continue to purchase from your store over a given period. It is calculated by taking the number of customers at the end of a period minus new customers acquired, divided by the number of customers at the start of the period.
A post-purchase flow is a sequence of automated communications and experiences delivered to customers after they complete a purchase. It typically includes order confirmations, shipping updates, review requests, cross-sell recommendations, and loyalty program invitations.
Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, calculated by dividing all sales and marketing expenses by the number of new customers gained during a specific period.
