Purchase frequency formula
Purchase Frequency measures how many orders the average customer places during a specific period. It is a core ecommerce retention metric because increasing purchase frequency usually leads to higher customer lifetime value and more predictable revenue.
Purchase Frequency equation
A higher Purchase Frequency means customers buy more often, increasing revenue per customer and reducing dependence on acquiring new buyers.
What affects Purchase Frequency?
Purchase Frequency improves when customers repeatedly return to buy because of strong products, excellent customer experience, effective email marketing and loyalty programs.
Purchase Frequency example
What is a good purchase frequency?
A good Purchase Frequency depends on your products, buying cycle and customer behavior. Stores selling consumables or subscription products generally achieve higher purchase frequencies than businesses selling products that customers buy only occasionally.
Low
Most customers purchase only once, making growth highly dependent on acquiring new buyers.
Average
Some customers return for additional purchases, but there is significant opportunity to improve customer loyalty.
Healthy
Customers purchase regularly, creating stronger revenue per customer and a more stable ecommerce business.
Excellent
Customers buy frequently, increasing lifetime value, improving retention and reducing long-term acquisition costs.
- Purchase Frequency measures how often customers place orders during a given period.

Common purchase frequency mistakes
Purchase Frequency is a useful customer retention metric, but incorrect data or missing context can make the result misleading. Avoid these common mistakes when evaluating how often customers buy from your store.
Using different reporting periods
Total orders and total customers must cover the same period. Comparing monthly orders with annual customer data produces an inaccurate Purchase Frequency.
Counting customers more than once
Use the number of unique customers, not the total number of customer records or transactions. Duplicate customers can artificially reduce or increase the result.
Ignoring the product buying cycle
Purchase Frequency varies by product type. Consumables and subscription products naturally generate more repeat orders than durable or occasional purchases.
Assuming more orders always mean more profit
Higher Purchase Frequency is valuable only when repeat orders remain profitable. Discounts, free shipping, refunds and low-margin products can reduce the value of frequent purchases.
Why purchase frequency matters in ecommerce
Purchase Frequency is one of the strongest indicators of customer loyalty. When customers buy more often, your Shopify store generates more revenue from existing customers, increases Customer Lifetime Value and becomes less dependent on acquiring new buyers through paid marketing.
What affects purchase frequency?
- Customer satisfaction and product quality.
- Email marketing and post-purchase communication.
- Loyalty and rewards programs.
- Product replenishment cycles.
- Upselling, cross-selling and subscription offers.
Frequent purchases should also be profitable
A high Purchase Frequency is valuable only when repeat orders generate healthy margins. Discounts, shipping costs, refunds and low-margin products can reduce the profit created by returning customers.
MarginLab combines Purchase Frequency with Customer Lifetime Value, product margins, discounts, refunds and Shopify profitability, helping merchants understand which customers drive long-term business growth.

These are some of the most common questions about Purchase Frequency, repeat orders and ecommerce customer retention.
What is Purchase Frequency?
Purchase Frequency is the average number of orders placed by each customer during a specific reporting period. It helps ecommerce businesses understand how often customers return to buy again.
How do you calculate Purchase Frequency?
Purchase Frequency is calculated by dividing total completed orders by the number of unique customers during the same period. For example, 3,200 orders divided by 2,000 customers equals a Purchase Frequency of 1.60.
What is a good Purchase Frequency?
A good Purchase Frequency depends on your product category and buying cycle. Consumable, subscription and replenishment products usually generate more frequent purchases than durable or occasional products.
How can I increase Purchase Frequency?
You can increase Purchase Frequency through post-purchase emails, replenishment reminders, loyalty programs, subscriptions, product bundles, cross-selling and a strong customer experience.
What is the difference between Purchase Frequency and Repeat Purchase Rate?
Purchase Frequency measures the average number of orders per customer. Repeat Purchase Rate measures the percentage of customers who complete at least one additional purchase after their first order.
How does Purchase Frequency affect Customer Lifetime Value?
Higher Purchase Frequency normally increases Customer Lifetime Value because each customer generates more orders and revenue throughout their relationship with your business.
Can higher Purchase Frequency reduce profit?
Yes. Frequent purchases may still produce weak profit if they depend on heavy discounts, free shipping, low-margin products or expensive retention campaigns. Repeat order volume should always be evaluated together with profitability.
