Surcharging
What Is Surcharging? Definition and How It Works
Definition
Surcharging is the practice of adding a fee to the purchase price when a customer pays by card, to recover some or all of the merchant's card acceptance costs. Surcharging shifts part of the payment processing cost from the merchant to the customer choosing to pay by card, and is subject to significant variation in legal permissibility across jurisdictions, banned for consumer cards in the EU and UK, permitted in the US under certain conditions, and, in Australia, set to be removed on designated card networks from 1 October 2026 following the Reserve Bank of Australia's 2026 decision.
How it works
A merchant that surcharges displays a standard price and adds a surcharge at payment when the customer selects a card method. The surcharge must be disclosed before the customer finalises the transaction. In card-present environments, disclosure must appear on signage; in e-commerce, it must be displayed before checkout completion.
Where surcharging is permitted, card scheme rules cap the surcharge at the merchant's actual cost of acceptance for that card type, typically the effective MDR. Merchants cannot surcharge above their actual processing cost, and cannot profit from surcharging.
Cash discounting is a related but legally distinct practice: the listed price is the card price; cash or bank transfer customers receive a discount. This is more widely permitted in the US than surcharging because it is structured as a discount rather than an added fee.
Why it matters
Card acceptance costs, interchange, scheme fees, and acquirer margin, typically run 1.5%–3.5% of transaction value. For merchants with thin margins, this cost is material. Surcharging transfers some of this cost to customers choosing the more expensive payment method.
Surcharging can also influence payment method mix: customers aware that card payment costs more may choose to pay by cash, bank transfer, or alternative method, shifting transaction mix toward lower-cost rails. In markets with strong A2A payment infrastructure, visible pricing differentials have contributed to consumer adoption of Pay by Bank.

Frequently asked questions
Is surcharging legal?
Surcharging legality varies by jurisdiction. In the EU, surcharging consumer debit and credit cards subject to the Interchange Fee Regulation is prohibited; commercial cards may be surcharged. In the UK, surcharging consumer cards has been banned since January 2018. In the US, surcharging is generally permitted subject to state-level restrictions and card scheme rules capping the surcharge at the merchant's actual cost. In Australia, surcharging on eftpos, Mastercard, and Visa is currently permitted subject to reasonable cost recovery rules, but the Reserve Bank of Australia has decided to remove it on these networks from 1 October 2026.
What is the difference between surcharging and cash discounting?
In surcharging, the base price is the cash/non-card price and a fee is added for card payments. In cash discounting, the base price is the card price and a discount is offered for cash or alternative payment. The distinction matters legally: cash discounting is more widely permitted in the US because it is structured as a discount rather than a surcharge.
Can merchants surcharge different amounts for different card types?
Scheme rules allow different surcharges for different card categories (credit vs. debit, consumer vs. commercial) where actual acceptance costs differ. Merchants cannot arbitrarily surcharge more for one card brand than another for equivalent product types. The surcharge for any card type cannot exceed the actual cost of acceptance for that type.
