TL;DR: Credit Card Interchange Fees
Credit card interchange fees (or “swipe fees”) are transaction charges paid by a merchant’s acquiring bank to the customer’s issuing bank every time a card payment is processed. Set by major card networks, these fees typically range from 1.5% to 3% of each transaction plus a small fixed fee, serving as the largest single component of payment processing costs for most businesses.
Key Takeaways
-
The Model: Interchange fees are designed to compensate issuing banks for managing transaction risk, providing fraud protection, and funding reward programs. The merchant receives the net amount after these fees are automatically deducted before settlement.
-
Ideal Context: Highly critical for SaaS and subscription businesses where card-not-present (CNP) transactions, recurring billing cycles, and high transaction volumes compound these fees quickly, acting as a direct drag on profit margins.
-
The Variables: Rates are non-negotiable and determined by card networks based on card type (premium rewards/corporate cards cost more), processing method (online carries higher fraud risk than in-person), and Industry Merchant Category Codes (MCC).
-
Pricing Breakdown: The total Merchant Discount Rate (MDR) consists of interchange fees (paid to the issuing bank), assessment fees (paid to the card network), and processor fees (paid to the payment processor). Only processor fees are negotiable.
Implementation Steps
-
Route to ACH: Transition high-ticket or predictable recurring transactions to ACH and bank transfers to swap percentage-based fees for low flat rates.
-
Optimize Data Submission: For B2B or corporate transactions, submit enhanced Level 2 and Level 3 data (tax amounts, line items) to qualify for lower interchange tiers.
-
Flag Transactions Correctly: Ensure your billing system accurately applies the “recurring indicator” to card networks to prevent transactions from defaulting to more expensive standard rates.
-
Maintain Card Freshness: Deploy card account updater services to proactively refresh expired card details, cutting down on failed payment retries and associated processor penalties.
The Bottom Line
Interchange fees are an inevitable cost of accepting card payments, but recurring revenue businesses do not have to accept maximum rates passively. By migrating to a robust platform like Ordway Recurring Billing Software or Ordway Subscription Invoicing Software, companies can leverage advanced automation, optimize data compliance, and intelligently route payments to safeguard their margins.
Are you looking to automate your payment routing and lower your processing costs, or are you currently trying to manage interchange fee transparency manually?
Credit card interchange fees are transaction charges paid by a merchant’s acquiring bank to the customer’s issuing bank every time a card payment is processed. Set by card networks like Visa and Mastercard, these fees typically range from 1.5% to 3% of each transaction—making them the largest component of payment processing costs for most businesses.
For subscription and SaaS companies processing thousands of recurring transactions, interchange fees compound quickly and can represent a significant drag on margins. This guide covers how interchange fees work, what determines the rate you pay, and practical strategies to reduce your costs.
What are credit card interchange fees
What are credit card interchange fees and why do they exist?
Credit card interchange fees—often called “swipe fees”—are transaction charges paid by a merchant’s acquiring bank to the customer’s issuing bank. Card networks like Visa and Mastercard set these rates, which typically range from 1.5% to 3% of the transaction amount plus a small fixed fee.
Interchange fees compensate the issuing bank for handling transactions, providing fraud protection, and funding customer reward programs. Every time a customer pays with a credit card, the merchant receives less than the full sale amount because interchange is deducted before settlement.
How credit card interchange fees work
How do interchange fees flow through a card transaction?
When a customer swipes, taps, or enters their card online, the transaction passes through several parties before the merchant receives funds. The merchant never sees the full transaction amount—the acquiring bank deducts fees, including interchange, before depositing funds.
Here’s how the money moves:
- Cardholder: Initiates payment using their credit card
- Merchant: Submits the transaction to their acquiring bank
- Acquiring bank: Routes the transaction through the card network
- Card network: Facilitates authorization and determines the interchange rate
- Issuing bank: Approves the transaction and collects the interchange fee
Who sets and collects credit card interchange fees
Who determines interchange rates and who receives the money?
Card networks—Visa, Mastercard, Discover, and American Express—set interchange rates. Individual banks and payment processors do not control interchange pricing. The issuing bank (the bank that issued the customer’s card) collects the interchange fee on each transaction.
Networks publish their rate schedules publicly and typically update them twice per year, in April and October. You can review the official guides on Visa’s and Mastercard’s websites to see current rates by merchant category and transaction type.
How much are credit card interchange fees
How much do interchange fees typically cost merchants?
Interchange fees generally range from approximately 1.5% to 3% of the transaction amount, plus a small per-transaction fee (often $0.10 to $0.30). The exact rate depends on card type, processing method, and merchant category.
Credit card interchange fees are typically higher than debit card interchange fees. Premium rewards cards and corporate cards carry the highest rates, while basic consumer cards fall on the lower end.
How credit card interchange fees are calculated
What factors determine the interchange rate on a transaction?
Several variables affect the specific interchange rate a merchant pays:
- Card type: Premium rewards cards and corporate cards have higher fees than standard credit cards
- Processing method: Card-present transactions (chip or tap) have lower rates than card-not-present transactions (online or keyed)
- Merchant category code (MCC): Industry classification affects fee tiers—supermarkets, airlines, and hotels each have different rates
- Transaction size: Some categories cap fees for large transactions
- Data submitted: Providing enhanced transaction data (Level 2 or Level 3) can qualify B2B transactions for lower rates
The basic formula for calculating interchange on a single transaction is:
Total Interchange Fee = (Transaction Amount × Percentage Rate) + Fixed Per-Transaction Fee
For example, on a $500 transaction with a 2.1% rate plus $0.10 fixed fee:
- Interchange Fee = ($500 × 0.021) + $0.10
- Interchange Fee = $10.50 + $0.10
- Interchange Fee = $10.60
Credit card interchange rates by network
What interchange rates do Visa, Mastercard, American Express, and Discover charge?
Rates vary by merchant category and transaction type. Here are general ranges for each major network:
| Card Network | Typical Interchange Rate Range |
|---|---|
| Visa | 1.4% – 2.5% |
| Mastercard | 1.5% – 2.6% |
| Discover | 1.55% – 2.5% |
| American Express | 2.3% – 3.5% |
Visa interchange rates
Visa publishes rates in their USA Interchange Reimbursement Fees guide. Their CPS (Custom Payment Service) rates offer lower interchange for transactions meeting specific data and processing requirements.
Mastercard interchange rates
Mastercard’s Merit rates reward merchants who submit enhanced transaction data. Their published interchange guide details rates by merchant category and card product.
American Express interchange rates
American Express historically operated as a closed-loop network with higher rates. Their OptBlue program allows smaller merchants to accept Amex at rates closer to Visa and Mastercard.
Discover interchange rates
Discover’s interchange rates are generally competitive with Visa and Mastercard, though their card volume is smaller in the U.S. market.
Card present, card not present, and recurring interchange rates
Why do interchange rates differ based on how the card is processed?
Risk level drives rate differences. Transactions where the card is physically present carry lower fraud risk and receive lower interchange rates.
Card present interchange rates
Card-present transactions occur when the customer physically presents their card and uses the chip or contactless tap feature. Card-present transactions carry the lowest interchange rates because fraud risk is minimal.
Card not present interchange rates
Card-not-present transactions include online purchases, phone orders, and manually keyed entries. Card-not-present transactions carry higher rates due to increased fraud risk—particularly relevant for e-commerce and SaaS businesses.
Recurring payment interchange rates
Card networks offer specific interchange categories for recurring transactions like subscription billing and membership fees. Properly flagging transactions as recurring can qualify merchants for lower rates, though billing system configuration matters.
Interchange pricing models for merchants
How do payment processors charge merchants for interchange fees?
The pricing model your processor uses determines both transparency and total cost.
Interchange plus pricing
Interchange-plus pricing passes through the actual interchange rate plus a fixed processor markup. Interchange-plus is the most transparent model and allows merchants to see exactly what they’re paying.
Flat rate pricing
Flat-rate pricing charges a single percentage on all transactions regardless of card type. Flat-rate pricing is simple but often results in overpayment on transactions that would qualify for lower interchange.
Tiered pricing
Tiered pricing groups transactions into qualified, mid-qualified, and non-qualified buckets. The processor determines classification, which often lacks transparency and can result in higher effective rates.
Subscription processor pricing
Subscription pricing charges a flat monthly fee plus wholesale interchange rates. Subscription pricing can benefit high-volume merchants with predictable transaction patterns.
Interchange fees vs assessment fees vs payment processor fees
What is the difference between interchange fees, assessment fees, and processor fees?
The total Merchant Discount Rate (MDR) includes three distinct components:
| Fee Type | Paid To | Purpose |
|---|---|---|
| Interchange fees | Issuing bank | Compensate for transaction risk, fraud protection, rewards |
| Assessment fees | Card network | Fund network operations and infrastructure |
| Processor fees | Payment processor | Cover processing services, gateway, support |
Interchange typically represents the largest portion of total processing costs. Only processor fees are negotiable—interchange and assessment fees are set by the networks.
How credit card interchange fees impact recurring revenue businesses
Why do interchange fees matter for SaaS and subscription businesses?
Recurring revenue models process the same customers repeatedly, which compounds the impact of interchange fees over time. High-volume, lower-ticket subscriptions feel the impact most acutely.
Most subscription transactions are card-not-present, meaning they automatically fall into higher interchange categories. Additional challenges include failed transactions that may incur retry fees, expired cards requiring re-authorization, and chargebacks that add costs beyond interchange.
For subscription businesses processing thousands of recurring payments monthly, even small rate differences translate to meaningful cost savings.
How to reduce credit card interchange fees
How can businesses reduce the interchange fees they pay?
While interchange rates are non-negotiable, merchants can optimize operations to qualify for lower rate categories.
1) Route recurring payments to ACH and bank transfers
ACH transactions have flat fees (typically $0.20–$1.00) rather than percentage-based interchange. For a $500 monthly subscription, ACH might cost $0.50 versus $10+ for credit card interchange. Global options like BACS, SEPA, and PAD offer similar savings for international customers.
2) Flag transactions with the correct recurring indicator
Card networks offer lower interchange categories for properly flagged recurring transactions. Missing or incorrect indicators can push transactions into higher-rate categories.
3) Use a card account updater service
Updater services automatically refresh expired or replaced card details, reducing failed transactions and the retry fees that follow.
4) Submit Level 2 and Level 3 data for B2B cards
B2B and corporate cards qualify for lower interchange when merchants provide enhanced data—tax amounts, customer codes, and line-item details. Enhanced data can reduce rates by 0.5% or more on qualifying transactions.
5) Apply a surcharge or convenience fee
Merchants can pass processing costs to customers in most U.S. states, though legal restrictions and card network rules vary. Surcharges apply specifically to credit cards, while convenience fees apply to alternative payment channels.
6) Negotiate interchange plus pricing with your processor
While interchange is fixed, processor markup is negotiable. Interchange-plus pricing provides the transparency needed to optimize, and volume commitments may unlock better processor rates.
7) Reduce chargebacks and failed transactions
Chargebacks incur fees beyond the original interchange, and failed transaction retries accumulate costs. Proactive dunning and clear customer communication help prevent payment failures.
Credit card interchange fee regulation in the United States
Are credit card interchange fees regulated in the United States?
Credit card interchange remains largely unregulated in the U.S., unlike debit card interchange which faces caps under federal law.
Credit card interchange regulation and the Credit Card Competition Act
The proposed Credit Card Competition Act would require large banks to enable routing through at least two unaffiliated networks, potentially increasing competition and lowering interchange rates. As of now, credit card interchange faces no federal caps.
Debit card interchange and the Durbin Amendment
The Durbin Amendment (part of the Dodd-Frank Act) capped debit card interchange fees for large banks at approximately $0.21 plus 0.05% per transaction. The Durbin Amendment is why some merchants prefer debit card acceptance—regulated rates are significantly lower than credit card interchange.
Lowering interchange costs with recurring payments automation
How can recurring billing automation reduce interchange and payment costs?
Automated billing platforms help subscription businesses optimize payment costs by routing payments to lower-cost methods like ACH, properly flagging recurring transactions to qualify for lower interchange categories, and maintaining card data freshness with automatic updater integrations.
Platforms like Ordway’s Recurring Payments solution integrate with multiple payment gateways and support ACH, cards, and global bank transfers to help subscription businesses optimize payment costs while automating the entire collection lifecycle.
Frequently Asked Questions about Credit Card Interchange Fees
Is it illegal for merchants to charge a 3% surcharge fee on a credit card transaction?
Surcharging is permitted in most U.S. states when properly disclosed, though some states prohibit surcharging and card network rules impose specific requirements.
Who decides the interchange fee on a credit card?
Card networks (Visa, Mastercard, Discover, American Express) set interchange rates, not individual banks or payment processors.
Are debit card interchange fees lower than credit card interchange fees?
Yes, debit card interchange is generally lower, especially for regulated banks under the Durbin Amendment, making debit a lower-cost payment method for merchants.
Do interchange fees apply to refunds and chargebacks?
Original interchange fees are typically not refunded when a transaction is reversed, and chargebacks may incur additional fees from the processor.
