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 changed debit economics permanently.
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.
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 illegal in Connecticut, Massachusetts, Maine, and Oklahoma. 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.
