A 3% credit card surcharge costs you more than a 2% cash-back card earns back. Before you pay, look for the surcharge notice at the register or a fee line on your bill. If you find one, pay with your debit card, since card network rules bar merchants from surcharging debit.
About a third of small businesses add a surcharge when you pay by credit card, according to a 2025 JD Power survey. Merchants use it to pass along what taking your card costs them, typically 1.5% to 3.5% of the sale, including the interchange fee that goes to the bank that issued your card.
The rules that allow surcharges also limit them. Visa caps a surcharge at 3% and Mastercard at 4%, and neither network lets it exceed the merchant’s cost or apply to a debit or prepaid card. A merchant that surcharges must post a notice at the entrance and the register. The fee must also appear as its own line on your receipt. Most states allow surcharges, but Connecticut, Maine, and Massachusetts ban them.
A cash discount works the other way. The posted price is the card price, and paying cash lowers it. Cash discounts are legal even where surcharges are banned. The networks’ debit rule doesn’t apply to them, so ask whether debit gets the cash price.
Before you pay a contractor or a medical office, ask whether a credit card payment adds a fee. If it does, pay with debit, cash, or a check where the business accepts one. If a merchant surcharges your debit card or skips the notice, report it to Visa or Mastercard.
Sometimes the surcharge is worth paying. A 3% surcharge on a $1,200 car repair adds $36, while a 2% card earns $24 back, so paying by card costs you $12. That $12 buys the federal right to dispute a credit card charge for work that isn’t done as agreed, which is worth having on a big job you pay for up front.
Make debit your default wherever a surcharge appears, and save the credit card for purchases where that dispute right is worth the fee.
