How to Use This Tool
Enter the card rate and fixed fee shown for your store, country and plan. Shopify's current US pricing page advertises online standard rates from 2.9% plus 30 cents, but rates vary by plan, location, card type and transaction channel. The defaults are therefore examples, not a universal table.
Third-party providers add another layer
Shopify's help documentation says third-party transaction fees can apply when an external provider processes the order, in addition to that provider's processing fee. Shopify Payments transactions generally avoid this extra layer. Enter the plan-specific percentage from your admin instead of assuming a rate copied from another country.
Refund economics are asymmetric
Some processing or third-party transaction fees are not returned when an order is refunded. The refund input estimates fees retained on refunded orders; verify the exact policy for the provider and payment method. The margin result shows how much of the pre-payment gross margin remains after fees.
Use basket-size scenarios
The table recalculates three order sizes using the same fee schedule. It makes low-priced products and split shipments easy to spot: a fixed charge can turn a nominal 2.9% rate into almost 9% on a five-dollar order.
