What is Interchange and How Does It Work?
Global Payment
What is Interchange?
Interchange, often referred to as interchange fees, is a cost that merchants pay to the card-issuing bank every time a customer uses a credit or debit card to make a payment. This fee is primarily designed to compensate the issuing bank for providing the payment infrastructure, covering the risks of fraud, and processing the transaction.
Interchange fees are typically a percentage of the transaction amount plus a fixed fee. These rates are determined by card networks like Mastercard, and others, and they vary based on the type of card used (credit vs. debit), the nature of the transaction (in-person or online), and the country in which the transaction occurs.
Understanding how interchange fees work is essential for businesses looking to manage their payment processing costs and optimize their profitability.
How to Calculate Interchange Fees?
The calculation of interchange fees is influenced by several factors, including:
-
Type of card: Credit cards often have higher interchange fees than debit cards, and premium cards (like rewards or business cards) tend to have even higher rates.
-
Transaction method: Transactions made in-person (card-present) typically have lower fees than online transactions (card-not-present), due to lower fraud risks.
-
Industry: Certain industries, such as e-commerce or travel, often face higher interchange fees due to their higher fraud risk.
-
Country or region: Interchange rates differ significantly by country, with the U.S. typically having higher rates compared to Europe, where regulations have capped interchange fees.
Here’s an example formula to understand interchange fees:
Interchange Fee = (Percentage Fee x Transaction Amount) + Fixed Fee
For example, if a Visa card charges a 1.5% interchange fee and a $0.10 fixed fee for a $100 transaction, the interchange fee would be:
(1.5% x $100) + $0.10 = $1.50 + $0.10 = $1.60
The exact interchange fees charged vary widely based on the above factors, making it important for merchants to understand how their industry and transaction types affect costs.
How do Interchange Fees Operate?
When a cardholder makes a purchase, the interchange fee is deducted before the payment is transferred to the merchant. Here's how the process works:
-
Cardholder makes a purchase: The customer uses their card to pay the merchant for goods or services.
-
Merchant's acquiring bank processes the transaction: The acquiring bank (merchant’s bank) forwards the transaction to the card network (UnionPay, Mastercard, etc.).
-
Card network contacts the issuing bank: The card network requests authorization from the issuing bank (customer’s bank) to approve or decline the transaction.
-
Issuing bank approves and charges interchange fee: If approved, the issuing bank sends the funds, minus the interchange fee, to the acquiring bank, which in turn deposits the payment into the merchant’s account.
The interchange fee typically goes to the cardholder’s issuing bank, which uses it to cover processing costs, risk management, and customer rewards.
Credit Card Interchange Fees & Debit Card Interchange Fees
Credit Card Interchange Fees
Credit card interchange fees are generally higher than debit card fees. This is because credit card transactions come with higher risks (e.g., the possibility of chargebacks) and often offer cardholder perks like rewards points or travel miles, which add to the cost for the issuing bank.
The average credit card interchange fee ranges between 1.5% to 3.0% of the transaction amount. High-end rewards cards or business credit cards can have even higher rates due to the benefits they offer to cardholders.
Debit Card Interchange Fees
Debit card transactions tend to have lower interchange fees since they draw directly from the cardholder’s bank account, reducing the risk for the issuing bank. Debit card interchange fees are generally lower, around **0.5% to 1.5%**.
In regions such as the European Union, interchange fees for debit cards are often regulated, with maximum caps set to reduce costs for businesses.
In What Ways do Interchange Fees Impact Cardholders?
Although interchange fees are not directly charged to cardholders, they can still indirectly impact them in several ways:
-
Higher prices: Merchants may increase their prices to offset the cost of interchange fees, meaning customers might pay more for goods and services.
-
Limited payment options: Some merchants may choose not to accept certain types of cards (especially high-reward or premium cards) due to their high interchange fees, limiting payment options for customers.
-
Less access to rewards: As interchange fees decrease (due to regulations or competition), card issuers may cut back on rewards programs, offering fewer perks like cashback, travel miles, or purchase protection.
Strategies for Businesses to Decrease Interchange Fees
Businesses can take several steps to reduce the impact of interchange fees:
-
Choose the right payment processor: It is crucial to cooperate with a payment processing platform that provides transparent rates and low fees. Global payment platforms and digital financial infrastructure providers like PhotonPay provide one-stop services including Global Accounts, Payouts, FX Management, etc., which can help merchants optimize payment processes and reduce costs.
-
Encourage debit card payments: Since debit card fees are typically lower, businesses can incentivize customers to use debit cards over credit cards to reduce costs.
-
Negotiate with processors: For large-volume merchants, negotiating better interchange rates based on transaction volume can lead to substantial savings.
-
Optimize transaction data: Providing complete and accurate data with each transaction (such as customer billing information or merchant category codes) can sometimes result in lower interchange fees for qualified transactions.
-
Consider surcharging or offering cash discounts: Some businesses choose to pass interchange fees to customers by applying a surcharge on credit card transactions or offering a discount for cash payments.
Frequently Asked Questions
1. Can interchange fees be negotiated?
In most cases, individual interchange fees are set by the card networks (Visa, Mastercard, etc.) and cannot be negotiated. However, large merchants can sometimes negotiate lower rates with their payment processors based on transaction volume.
2. Are interchange fees the same for all businesses?
No, interchange fees vary by industry, transaction type, and region. For example, e-commerce businesses might pay higher fees due to the card-not-present nature of transactions.
3. Who sets interchange fees?
Interchange fees are set by the card networks (Visa, Mastercard, etc.) and vary based on the type of card and transaction.
4. Can businesses pass interchange fees to customers?
In some countries or states, businesses can add a surcharge to cover interchange fees, though there may be legal restrictions on this practice. Alternatively, businesses can offer a discount for cash payments to offset the cost of card processing fees.
