Interchange fees: What they are and how they work

Every time a transaction is made via a card scheme (Visa, Mastercard, etc.), the acquirer pays the cardholder’s bank an interchange fee. The business then pays the interchange fee back as part of its card processing fees.

Card payment processing comes with three fees:

• Acquirer markup: Charged by the acquirer for acquiring the funds from your shopper

• Card scheme fees: Charged by the card scheme for using its network

• Interchange fee: Charged by the cardholder’s bank

Interchange fees make up the most significant chunk of card processing fees.

On average, interchange fees are around 0.3-0.4% of the transaction amount in Europe and 2% in the US.

Card schemes determine interchange fees and are non-negotiable. They are also regularly adjusted. For example, Visa and Mastercard publish new rates in April and October every year.

The most accurate and up-to-date way to find the current rates is to check the card scheme’s website. Below you can find the interchange rates for Visa and Mastercard in different regions:

Visa interchange rates: EU, US, SG, AU, IN Mastercard interchange rates: EU

Some card networks, including American Express and Discover, work slightly differently to Visa and Mastercard and don’t publish their rates online.

Many factors influence the interchange fee amount. Here are the key ones to be aware of and how they affect the amount you're charged:

Card scheme

Different card schemes charge different interchange rates. So the cost of a customer paying with a Visa card won't be the same as with a Mastercard.

Card-present vs. card-not-present

Card-present (CP) transactions, also known as face-to-face transactions, have lower interchange fees than card-not-present (CNP) transactions. This is because the risk of fraud is lower when the customer’s card is physically present.

Credit vs. debit cards

Credit and deferred debit cards have higher interchange fees than immediate debit and prepaid cards as the level of risk is considered higher.

Merchant category code (MCC)

Your assigned MCC can affect your interchange fees. For example, in the US and Australia, Visa and Mastercard grant lower rates to businesses like charities, travel agents, streaming services, and utilities.

Consumer vs. commercial

Commercial cards charge higher interchange fees than those issued to an individual.

Transaction regionality

Domestic transactions, where the card-issuing bank is in the same country as the business, are generally cheaper than cross-border transactions.

Rewards cards

If a customer uses a rewards card to pay, the interchange fees are generally higher. This is because the increased fees pay for the extras offered by rewards programs.

Can you control any of these factors?

Some of the factors above you can influence, but others you can't change. For instance, if you convinced your customers to buy more in-store than online, you could reduce your interchange fees.

When it comes to your MCC, however, you have no control. Your MCC is assigned to you and is dependent on the type of business you have.

Lowering your interchange fees may not result in more profit. By limiting your customers' choices, you could deter them from purchasing from your business. However, understanding the components of your card processing fees can help you better manage these costs.

Interchange++ (or Interchange Plus Plus) and Blended are the most widely used pricing models for card transactions. The main difference between the two is transparency in card processing fees.

Interchange++ shows you a detailed breakdown of the three card processing costs mentioned earlier: the acquirer markup, card scheme fee, and interchange fee.

You only pay the interchange fee the card issuer actually charged you. As interchange fees vary depending on many factors, they can sometimes be lower than a fixed rate.

The alternative to Interchange++ is Blended pricing. The Blended model charges an average card processing fee plus a fixed markup. You're charged the same markup for every transaction, and you can't see the split of the costs.

This makes it easy to understand, but intransparent. And there's no guarantee your processor will share any savings with you made from lower interchange fees.

Traditionally, there was very little transparency into how interchange fees were calculated. Large businesses with a high volume of transactions could negotiate lower fees, while smaller firms had to pay the full amount.

Markets dominated by the large international card schemes were most vulnerable. Businesses couldn't afford to refuse the payment methods most of their customers used.

Fortunately, recent progress has been made to standardize interchange fees, with stricter rules and fee caps introduced, and overall transparency increased.

Below is a breakdown of the domestic consumer interchange fee caps across different regions:

The Durbin Amendment (US only)

This amendment, enacted in 2010, is an example of a card processing fee cap for debit and prepaid card transactions.

The Durbin amendment is dependent on the size of the issuing bank's assets. If the issuing bank has assets of $10bn or more, its debit and prepaid cards will be charged regulated rates. These cards are then subject to an interchange rate of 0.05% + $0.21 or 0.05% + $0.22, depending on fraud prevention policies.

European Interchange Fee Regulation (IRF)

The European Economic Area (EEA) introduced interchange fee regulations in 2015, leading to heavy regulations where interchange fees are capped for consumer cards across all EEA countries. As a result, the EEA is now one of the cheapest options worldwide and is considered an excellent place to set up entities for cross-border transactions.

Since the UK’s withdrawal from the EU, the EEA fee caps no longer apply for transactions when an EEA-issued card is used to pay at a merchant located in the UK and vice versa.

The interregional caps, however, still apply for transactions at merchants located in the EEA and the UK. The EEA and UK interregional fee caps for card-present transactions are 0.20% for debit transactions and 0.30% for credit transactions. For card-not-present transactions, the fee caps are 1.15% for debit transactions and 1.50% for credit transactions.
