Interchange Fees in 2026: how merchants pay, and why it matters for which card you use
Interchange is the fee paid by the merchant's processor to the card-issuing bank every time you swipe. It explains why gas stations, hotels, and small merchants behave differently depending on which card you use, and why the Durbin Amendment reshaped debit economics.
2026 rate ranges: the numbers
Typical interchange per $100 transaction (2026)
Sources: Visa USA Interchange Reimbursement Fees (2026); Mastercard published merchant rates schedule (2026); 12 CFR 235.3 (Durbin cap for regulated issuers).
Credit card interchange
Typically 1.5-2.5% for consumer cards. Higher for premium rewards, business, and corporate cards. The merchant pays this on every credit-card transaction. This is why some merchants offer a cash discount: they are passing some of the interchange saving to the consumer.

Regulated debit (Durbin cap)
Banks with $10B+ in assets are subject to the Durbin Amendment (Dodd-Frank 2010). Their debit interchange is capped at $0.21 + 0.05% per transaction under 12 CFR 235.3. On a $100 transaction, that is $0.26, compared to $1.50-$2.50 for credit. This is why merchants prefer debit for large-ticket regulated-issuer transactions.
Note: in Corner Post v. Board of Governors (6 Aug 2025) a North Dakota federal court vacated Regulation II, holding the Fed exceeded its authority. The court stayed its own ruling pending the Board's appeal to the Eighth Circuit, so the $0.21 + 0.05% cap remains in effect for now.
PIN debit vs signature debit: the consumer impact
When you have a debit card and the terminal asks Credit or Debit, you are choosing the routing network, not the card type:
Choose “Credit” on a debit card
- Routes through signature-debit network (Visa/MC)
- Merchant pays slightly higher interchange
- No PIN required; signature or tap
- Fraud-protection chain: Reg E (unauthorized) + voluntary network chargeback
- Not the same as a credit card: still comes from your bank balance
Choose “Debit” and enter PIN
- Routes through PIN-debit network (Star, Pulse, NYCE)
- Merchant often pays lower interchange under Durbin
- PIN entry adds fraud-signal clarity (harder to clone)
- Transaction clears faster
- Still only Reg E protection
Surcharges and cash discounts in 2026
Credit-card surcharges are legal in most US states, but merchants must disclose them clearly and caps apply (typically 3-4% per Visa/MC rules). As of 2026, surcharges remain prohibited in Connecticut, Massachusetts, and Maine. Oklahoma's anti-surcharge statute is still on the books but has been struck down by the federal courts as unconstitutional, so surcharging is permitted there in practice. Cash discounts, where a lower price is offered for cash, are always legal everywhere.
Some merchants now use dual-pricing terminals that show both the cash price and the credit price simultaneously. This is a legal alternative to a surcharge and is becoming more common at gas stations, medical offices, and service businesses.
