For retailers and restaurateurs, credit and debit card payments are a routine part of doing business. However, many business owners are unaware of the actual costs involved in processing these transactions. One of the most important components of those costs is the interchange fee.
Interchange fees are often misunderstood, yet they play a crucial role in how much merchants pay to accept card payments. This guide breaks down what these fees are, how they are determined, and what retailers and restaurant owners can do to manage them effectively.
What Are Interchange Fees?
Interchange fees are charges that merchants pay every time a customer uses a credit or debit card. These fees are set by card networks like Visa and Mastercard and are paid to the bank that issued the customer’s card.
Although you pay these fees indirectly through your payment processor, they are a major component of the total cost of accepting card payments.
Who Sets and Collects Interchange Fees?
The card networks (Visa, Mastercard, etc.) set the fee structures. However, the money collected goes to the cardholder’s bank, not the network itself. This fee compensates the issuing bank for the risks and costs of facilitating the transaction, including fraud protection and payment guarantees.
How Interchange Fees Work in a Transaction
When a customer pays with a card, the payment processor deducts the interchange fee from the total transaction amount before it is deposited into your account. So, if a customer pays $100 and the interchange fee is 2 percent, you receive $98, and the remaining $2 goes to the card issuer.
Why Interchange Fees Matter for Your Business
For small business owners, especially those in retail or food service, interchange fees can significantly impact profit margins.
Understanding these fees allows you to make informed decisions when selecting payment processors and pricing your goods or services.
Fees Add Up Quickly
While the fee for each transaction may seem small, it adds up over hundreds or thousands of sales. If your business processes $50,000 in card payments per month, even a 0.5 percent difference in fees can result in a loss of $250 monthly or $3,000 per year.
Affects Pricing and Profitability
Businesses with thin margins, such as quick-service restaurants or convenience stores, must carefully factor in interchange fees when setting prices. Even a small increase in fees can erode profits if not accounted for properly.
Factors That Influence Interchange Fees
Interchange fees are not fixed for all transactions. They vary depending on several factors. Understanding what influences these charges can help you reduce costs and avoid unnecessary fees.
The more you know about how these fees are structured, the more control you have over your payment processing expenses.
Card Type
Rewards cards and business credit cards often have higher interchange fees than basic debit cards. This is because they come with perks like points or cashback, which the issuing bank funds in part through higher fees.
Transaction Type
Card-present transactions, where the card is physically swiped, inserted, or tapped, generally carry lower fees than card-not-present transactions, such as online or phone payments. This is due to the lower risk of fraud when the card is present.
Merchant Category Code (MCC)
Your business type is assigned a specific MCC, which can influence the fees you pay. Restaurants, retail stores, gas stations, and service providers each have different standard interchange rates. Some categories qualify for lower rates based on risk or industry standards.
Processing Method
Using outdated terminals or not capturing all necessary data during a transaction can result in a higher “downgraded” interchange fee. Ensuring your terminal is EMV-enabled and supports contactless payments can reduce these costs.
The Structure of Interchange Fees
Interchange fees are usually structured as a percentage of the transaction plus a fixed fee. The average rate varies depending on the factors mentioned earlier.
For example, a common interchange rate might be 1.65 percent plus 10 cents. On a $100 sale, that would be $1.75 in total fees.
Debit vs Credit
Debit card transactions typically have lower interchange fees than credit cards, especially if they are processed using a PIN. Credit cards involve higher risk for issuers, which is reflected in the higher fee structure.
Rewards Cards and Premium Products
Cards that offer travel rewards, airline miles, or business benefits often have significantly higher interchange rates. If your customer base frequently uses these cards, your average processing cost will be higher.
Interchange Plus vs Flat Rate Pricing
When working with a payment processor, you will encounter different pricing models. Two common options are interchange plus and flat rate pricing.
Knowing how each works is crucial for understanding how much of your transaction fee goes toward interchange costs and how much is markup from the processor.
Interchange Plus Pricing
In this model, you pay the actual interchange fee set by the card network plus a fixed markup from the processor. This method is more transparent and allows you to see exactly where your money is going.
If a transaction carries an interchange fee of 1.8 percent and your processor charges 0.3 percent plus 10 cents, your total cost would be 2.1 percent plus 10 cents. This model benefits businesses with high volumes or lower-risk transactions.
Flat Rate Pricing
Flat rate pricing combines interchange and processor fees into a single rate, such as 2.9 percent plus 30 cents per transaction. While easier to understand, flat rates often include a higher markup to cover fluctuations in interchange fees.
Flat rates may work well for small or seasonal businesses that value simplicity, but larger businesses may save more with interchange plus pricing.
How to Reduce Interchange Fee Expenses
You cannot eliminate interchange fees, but you can reduce their impact through smart business practices and better negotiation with payment providers.
Understanding where your money is going empowers you to take action that can result in noticeable savings over time.
Encourage Debit Over Credit
Since debit card transactions usually have lower fees, you can subtly encourage customers to use debit by promoting PIN-based transactions or offering incentives for cash or debit payments.
Use Proper Terminal Technology
Ensure that your POS system supports EMV, NFC, and tokenization. Transactions that are processed through outdated systems are more likely to incur higher fees due to added risk.
Minimize Downgraded Transactions
Always enter all required transaction data, including billing zip code and CVV for card-not-present transactions. Missing data can cause a downgrade, triggering a higher fee tier.
Choose the Right Processor
Not all processors are equally transparent. Work with one that offers interchange plus pricing and helps you understand your monthly statement. Avoid providers who hide interchange details behind flat rates without disclosing true costs.
Consider Your MCC Classification
If you suspect your merchant category code is inaccurate or outdated, contact your processor. An incorrect MCC can result in higher interchange fees. Ensuring you are properly classified might qualify you for lower rates.
Understanding Monthly Statements
To manage your interchange expenses effectively, you need to know how to read your monthly processing statement. These documents detail the interchange fees, processor markups, chargebacks, and other charges you incur.
Familiarity with your statement helps you catch errors, identify trends, and make informed decisions about whether to switch providers or renegotiate rates.
Look for Fee Breakdowns
Statements should show each type of card used and the associated interchange fee. If you only see a flat rate, you may be on a pricing model that hides the true cost of interchange.
Watch for Downgrades
Frequent downgrades can inflate your average interchange rate. These will usually appear as “non-qualified” or “mid-qualified” transactions and should prompt you to review how your terminal is processing payments.
Compare Monthly Trends
Track your interchange costs over several months. If fees are rising faster than sales, it may indicate inefficient processing or a shift in the type of cards customers are using.
Regulatory Landscape Around Interchange Fees
Interchange fees are a hot topic for regulators, especially in regions where they are considered high. Although changes in legislation take time, staying informed about regulatory developments helps you prepare for shifts in processing costs.
For example, the European Union has capped interchange fees at 0.3 percent for credit cards and 0.2 percent for debit cards. Similar proposals have been discussed in the United States, particularly for debit card transactions.
The Durbin Amendment
In the U.S., the Durbin Amendment limits interchange fees on debit card transactions for banks with assets over $10 billion. While this benefits merchants, not all transactions are eligible, and the rule only applies to regulated banks.
Ongoing Legal and Political Pressure
Retail associations continue to lobby for interchange fee reform. If you process a high volume of card transactions, particularly in the restaurant or grocery industry, regulatory changes could significantly affect your costs.
Conclusion
Interchange fees are a core part of payment processing and have a direct impact on your bottom line. While they may seem like a hidden cost, they are not beyond your control.
By understanding how interchange fees work, choosing the right pricing model, maintaining updated systems, and analyzing your monthly statements, you can manage these costs effectively. Retailers and restaurateurs who stay proactive about interchange fees will be better equipped to protect their profits and offer fair, transparent pricing to their customers.
