Example

Your store processed 1,256 returning customer orders in April with $4,892 in total transaction costs:

Component	Amount	% of RC Revenue
RC Gateway Cost	$3,841	2.8%
RC Other Transaction Cost	$1,051	0.8%
RC Total Transaction Cost	$4,892	3.6%

Transaction costs for returning customers are typically lower as a percentage of revenue compared to new customers due to higher average order values.

How It Works

Returning Customer Transaction Cost aggregates all payment-related fees specifically for repeat buyer orders. Gateway costs are pulled from Shopify’s transaction data for orders where the customer has at least one prior purchase. Other Transaction costs come from user-defined order cost entries with the “Transaction” category. This metric is deducted from RC CM1 to calculate RC CM2.
