What Are Interchange Fees?

Aug 4, 2023

It’s almost impossible for businesses to operate without accepting credit or debit cards, or both. Banks offer credit and debit cards to make it easier for consumers to make payments and faster for businesses to get paid. With each transaction, businesses pay a small fee—an interchange fee—in exchange for this value.

What is Interchange?

Interchange fees, also called “swipe fees”, play an important role in the payment ecosystem. Processing credit and debit card transactions is a complex process that involves multiple steps and many different organizations: the credit card issuer, acquiring bank, and card processing network, to name a few.

Interchange refers to the fees paid to the credit card issuer from the merchant’s bank for credit and debit card transactions. The interchange fee is a small percentage of the transaction amount plus a flat fee, for instance 1.19% + $0.05. The fee amount is set by the payment network, i.e. Visa, Mastercard, Discover, and American Express, and apply to almost all card transactions.

Interchange fees are just one of the fees that make up the overall cost that merchants pay for accepting credit cards. The overall cost is reflected in the merchant discount rate, or MDR, which includes:

  • Interchange fee
  • Payment processor markup, paid to the payment processor or acquiring bank
  • Assessments, charged by the payment network
  • Other fees charged by the merchant’s bank or payment service provider.

What Affects Interchange?

The exact interchange fee amount can vary depending on several factors.

  • Card brand: Visa, Mastercard, Discover, American Express
  • Card type: rewards card, corporate card
  • Transaction type: in-person, online, contactless
  • Business size and industry
  • Credit card program type, airline rewards, cash back rewards

Example of How Interchange Fees Work

Let’s say a customer makes a $100 credit card purchase a retail store and the interchange fee for the card is 2% of the transaction plus $0.15. The interchange fee for this transaction would be:

Interchange Fee = (Transaction Amount x 2%) + $0.15
Interchange Fee = ($100 x 0.02) + $0.15
Interchange Fee = $2 + $0.15
Interchange Fee = $2.15

The merchant’s bank processes the transaction. Before the merchant is paid, the $2.15 interchange fee is deducted from the transaction and paid to the customers card issuer. The merchant will receive $97.85.

Are Interchange Fees Beneficial?

Interchange fees are often subject to debate and scrutiny, criticized for lack of transparency, unfair, and expensive for businesses. Like other business costs, interchange fees do provide a number of benefits for the payment ecosystem.

  • Maintaining payment infrastructure, including secure data transmission, fraud prevention measures, and technological advancements.
