What is an Interchange Fee?

What are interchange fees? Interchange fees are transaction fees that merchants must pay when processing credit or debit card payments.

An interchange fee is a fee merchants pay to the bank issuing a customer’s credit or debit card whenever a transaction is processed. This fee is a crucial part of the payment system, ensuring that card-issuing banks are compensated for handling the transaction.

For example, when you swipe your credit card at a store or enter your card details online to make a purchase, the merchant pays an interchange fee to your bank. This fee is typically a small percentage of the amount from credit or debit card transactions, along with a fixed amount. It’s not a flat fee.

Interchange fees are applied in various settings, from everyday purchases like groceries and gas to online shopping and large business transactions. Whether you’re buying a coffee or booking a flight, interchange fees are silently at work in the background, helping to facilitate the smooth operation of the global payments system.

How do Interchange Fees Work?

The process of how interchange fees work

In a credit or debit card transaction, interchange fees, which are a type of transaction fees, play a pivotal role in the payment process. When you make a purchase, the acquiring bank—responsible for processing card payments on behalf of the merchant—funnels a portion of the transaction amount to the card network, such as Visa or Mastercard.

The majority of this fee goes to the card issuer, the bank that provided the card to the customer. However, a small percentage is returned from the issuer to the card network.

Interchange fees help cover various costs, including the issuance of credit and debit cards, and the operational expenses tied to card usage. Additionally, these fees often fund rewards programs and fraud prevention efforts, ensuring the continued efficiency and security of the payment system.

The Factors that Affect Interchange Rates

Card type

Different types of cards, such as credit or debit cards, as well as premium or business cards, come with varying interchange rates. Premium or business cards often carry higher fees, which can affect the overall cost of processing payments.

Transaction type

The way a transaction is conducted—whether in-person, online, or over the phone—can influence the interchange rate. Card-not-present transactions, like those made online, usually incur higher fees due to increased risk compared to credit card transactions.

The card network

The payment network (Visa, Mastercard, etc.) that processes the transaction also impacts the interchange rate. Credit card companies have their own network and fee structure, and the rates can vary even for similar types of transactions.

Rewards programs

Cards that offer rewards to customers, such as cashback or travel points, typically have higher interchange rates. The additional cost helps fund these reward programs, which are an attractive feature for cardholders.

Network partner programs

Some payment networks offer programs with partner banks or service providers, which can influence interchange rates. Participation in these programs may result in different fee structures that could raise or lower your business's costs.

Merchant category code (MCC)

Your business type, classified under a Merchant Category Code (MCC), affects the interchange rate. Certain industries, especially those considered higher risk or with lower transaction volumes, may face higher fees.

Merchant size and volume

Larger businesses or those with higher transaction volumes often have more leverage to negotiate lower interchange rates. Your size and the number of transactions you process can significantly impact your overall fees, potentially leading to lower interchange fees.

Issuing banks

The bank that issued your customer’s card, known as the issuing bank, plays a key role in setting the credit card interchange fees. Different banks may have different fee structures, affecting what you ultimately pay.

Which Cards Charge Higher Interchange Fees?

If you’re a merchant, knowing which cards cost you more to process can save you money. These higher interchange fees, often referred to as swipe fees, can significantly impact both merchants and consumers during card transactions. As mentioned previously, premium and business credit cards—like those offering travel rewards or cashback—come with higher interchange fees than regular credit or debit cards.

Final Thoughts

Understanding the factors that shape interchange rates puts you in the driver’s seat when it comes to managing your payment processing. With this insight, you can negotiate better rates, choose the most cost-effective card networks, and streamline your transactions to keep fees in check. Managing these costs effectively isn’t just about cutting expenses—it’s about setting your business up for greater efficiency and profitability. When you’re informed, you’re empowered to make smarter decisions that can positively impact your bottom line.
