Pricing Model
A surcharge is a fee added to a transaction when a customer pays by credit card. It is disclosed separately from the base price and allows merchants to pass card processing costs to card-paying customers. Surcharging is one of the most regulated pricing practices in payment processing.

Important compliance note: Surcharging is prohibited or restricted in some U.S. states. Card network rules require advance registration, specific signage, and receipt disclosures. Surcharging debit cards is prohibited under card network rules. Rules can change. This page is educational — always verify current state laws and card network requirements with your processor and legal counsel before implementing any surcharge program.
Quick Answer
A surcharge adds a fee to the base price when a customer pays by credit card. The fee must be disclosed separately, cannot exceed the merchant's actual cost of acceptance (capped at a network-defined maximum), is prohibited on debit transactions, and requires advance registration with card networks. Some states prohibit or limit surcharging by law.
A surcharge is added to a transaction's base price when the customer chooses to pay by credit card. For example: a $100 item with a 2.5% credit card surcharge would cost $102.50 when paid by credit card, and $100 when paid by cash, debit, or other non-surcharged payment method.
Card networks (Visa, Mastercard) permit surcharging for credit card transactions under specific rules. Merchants must notify their acquirer before implementing a surcharge program — Visa requires at least 30 days' advance notice; verify the current Mastercard notification period with your acquirer. Merchants must also display the surcharge prominently at entry and point of sale, disclose the surcharge on receipts, and cap the surcharge at the network-defined maximum — historically 3% for Visa and 4% for Mastercard, each also limited by the merchant's actual cost of acceptance. Verify current limits directly with each network and your processor.
Surcharging is not permitted for debit card transactions under card network rules — regardless of whether the debit card runs as credit or debit at the terminal.
Advance notification
Must notify acquirer before implementing a surcharge program. Visa requires at least 30 days' advance notice. Verify the current Mastercard notification period with your acquirer.
Signage at entry
Required signage disclosing that a surcharge applies to credit card payments must be displayed at the store entrance or website homepage.
Point-of-sale disclosure
Surcharge must be disclosed at the point of sale before the customer completes the transaction.
Receipt disclosure
Surcharge amount must appear as a separate line item on the receipt.
Maximum cap
Surcharge cannot exceed the merchant's actual cost of acceptance or the card network's maximum (verify current limits directly with your processor).
Credit cards only
Debit card transactions cannot be surcharged under card network rules — this applies to debit cards run as 'credit' at the terminal as well.

Verification note
Visa and Mastercard operating rules establish network-wide requirements for surcharging — including advance notification requirements, maximum surcharge caps, disclosure signage, and receipt requirements. Visa has historically capped credit card surcharges at 3%; Mastercard has historically capped them at 4%; both limits are also constrained by the merchant's actual cost of acceptance. Visa requires at least 30 days' advance notice to the acquirer; verify the current Mastercard notification period with your acquirer. These rules govern card-network obligations only and do not establish whether surcharging is permissible under applicable state law — state requirements vary and are a separate question. Both networks restrict surcharging to credit card transactions; debit and prepaid card transactions are not eligible. Caps and notification requirements are subject to change. Merchants must verify current state laws and card network requirements with their processor and qualified legal counsel before implementing any surcharge program.
