What is the Mastercard Interchange?
Definition and Purpose
Mastercard interchange rates are integral to the payment card transaction ecosystem, representing the fee collected by the customer's credit card bank from the merchant’s bank for each transaction made using a Mastercard. These rates are set by Mastercard annually and apply uniformly across all payment processors, ensuring consistency and predictability in transaction costs.
Interchange rates contribute to the Merchant Discount Rate (MDR), which includes other components like network fees and acquirer markups, ensuring the payment network remains secure and sustainable.

Mastercard Interchange Rates
How Rates are Determined
Mastercard sets interchange rates by balancing the benefits to cardholders with the costs imposed on merchants. These rates depend on various factors, such as:
- Card Type: Different rates apply to various cards (e.g., consumer credit, business debit card, and prepaid cards). Business debit cards, in particular, can result in varying fee structures that merchants need to consider in their payment processing.
- Transaction Type: Card-present transactions usually incur lower fees compared to card-not-present transactions due to the reduced fraud risk.
- Merchant Category Code (MCC): Merchants are categorized by industry, with each category subject to different rates.
- Purchase Amount: Larger transactions may attract lower percentage fees but higher fixed fees.

Interchange Fees
Types of Interchange Fees
Mastercard’s interchange fees vary based on the specifics of the transaction. These fees are collected by the MasterCard card issuer during transactions. Categories include:
- Business and Consumer Debit Cards: These often incur higher fees due to the additional complexity and benefits associated with such transactions.
- Standard Credit Cards: Baseline rates apply, with premium cards attracting higher fees due to the benefits they offer cardholders.
These fees are a part of the Merchant Discount Rate, where the acquirer adds a markup over the interchange fee. This markup is determined by the acquirer’s pricing strategy, which reflects the services provided to the merchant.
Mastercard Network Fees
New Mastercard Network Fees
Mastercard has introduced several network fees to enhance the security and efficiency of transactions. One notable addition is the Digital Enablement Fee for card-not-present transactions, particularly in Canada, where it stands at 0.02% per transaction with a minimum of $0.02 and a maximum of $0.20. These fees are applied to all purchase transactions conducted with a Mastercard. These updates also include adjustments to fraud mitigation fees for services like Address Verification Service (AVS) and Card Verification Code.
Acquirer Role
The Role of the Acquirer in Determining Interchange Rates
Acquirers are financial institutions that enable merchants to accept card payments. While Mastercard sets the interchange rates, acquirers determine the overall Merchant Discount Rate (MDR) by adding their own markup. This rate reflects the acquirer’s risk assessment, service levels, and pricing strategy, which can influence the total cost for the merchant.
Understanding these fees is crucial for merchants accepting Mastercard cards to effectively manage transaction costs.
