Total payment gateway fees for orders placed by returning customers.

Formula Components

Data Source	Shopify
Aggregation	Sum

Example

Your store processed $2,089 in gateway fees from returning customers in January:

Customer Type	Orders	Gateway Cost	Avg per Order
Returning Customers	835	$2,089	$2.50
New Customers	412	$1,247	$3.03

Returning customers have lower per-order gateway costs due to higher average order values and repeat purchase patterns.

How It Works

This metric sums all payment gateway processing fees—including percentage-based fees and flat per-transaction charges—for orders placed by returning customers. Shopify identifies returning customers as those who have at least one prior order in your store history.
