The merchant’s acquiring bank or other financial institution deducts that charge before depositing the proceeds. The MDR normally combines interchange paid to the cardholder’s issuing bank, payment-network assessments, and the acquirer’s or processor’s markup and service charges.
The card user does not usually see a separate fee on a normal purchase. Acceptance costs can still reach consumers indirectly through overall prices, or directly through a surcharge where applicable law and network rules allow one. The amount passed through varies with competition, customer sensitivity and the merchant’s pricing choices; it is not a fixed, equal charge paid by every shopper.

What “swipe fee” means
“Swipe fee” is an industry nickname, not a separate fee that applies only when a plastic card is physically swiped. The same economics generally apply to chip, contactless and online card payments. In formal terms, the merchant pays a merchant discount rate under its acceptance agreement with an acquiring institution. That rate may be quoted as a percentage, a per-transaction amount, or both.

A Congressional Research Service (CRS) explanation places the MDR typically around 1% to 3% of a transaction, while noting that arrangements can combine a percentage with a fixed amount. That range is an illustration of the structure, not a guaranteed current price for any particular business. A small retailer, a large online merchant and a restaurant can receive very different offers.

How a card payment moves through the system
The four parties in a typical transaction
- Cardholder and issuing bank: The customer presents a card issued by a bank or other issuer. The issuer authorizes the purchase and later receives interchange through the payment network.
- Merchant and acquiring bank: The merchant submits the transaction through an acquirer, which provides the account and deposits the merchant’s proceeds after deducting the MDR.
- Payment network: The network carries authorization and settlement messages and sets interchange schedules and network charges for its system.
- Processor or other service provider: Processing services capture, route and settle transactions. Their charges are part of the merchant’s overall acceptance cost and are often negotiable.
Authorization confirms that the issuer will honor the transaction under the network’s rules. Settlement later moves funds from the issuer through the network and acquirer to the merchant. The merchant’s contract determines how the different costs appear on its statement; the business normally sees one combined discount or a set of line items rather than paying interchange directly.
What makes up the merchant discount rate
| Component | What it pays for | Typical recipient | What merchants should know |
|---|---|---|---|
| Interchange | Compensates the issuing side for authorization, settlement, fraud controls and related card-program costs. | Cardholder’s issuing bank | Usually the largest MDR component. The network publishes schedules, but the merchant does not normally remit this amount directly to the issuer. |
| Network assessment and related network fees | Use of the payment network, rules, connectivity and settlement infrastructure. | Payment network | Separate from interchange and generally tied to the network’s schedule and transaction characteristics. |
| Acquirer or processor charges | Merchant account, gateway, authorization, routing, settlement and other acceptance services. | Acquiring institution and processing providers | Often the most negotiable portion. Quotes may combine a percentage markup, fixed amount and service fees. |
Visa describes the merchant’s obligation as a negotiated “merchant discount” paid to its financial institution, rather than interchange paid directly by the merchant. Mastercard likewise describes interchange as one component of the MDR established by acquirers and paid by merchants for acceptance services. Those network descriptions explain why comparing an interchange table alone will not reveal a merchant’s total cost.
A $100 transaction, step by step
Suppose a merchant has an MDR of 3% and accepts a $100 purchase. The acquirer deducts $3, so the merchant receives $97. The $3 is then allocated among the acquirer, issuer and service providers according to the applicable interchange schedule, network charges and processing agreement. The customer’s receipt still shows a $100 purchase unless the merchant separately applies a permitted surcharge.

This calculation is a CRS illustration, not a promise that a current merchant will pay exactly 3%, nor does it show the internal split for a particular network or contract. A quote with a 2.4% percentage plus a fixed amount, for example, produces a different effective cost on a small ticket than on a large one.

Why one merchant or transaction costs more than another
Card product and rewards tier
Interchange schedules can distinguish among basic, rewards and premium products. Rewards cards may carry different rates because the issuing bank funds points, cash back or other benefits. The card’s product category is only one input; the merchant’s agreement and any processor markup determine the final MDR.
How the card is presented
Card-present transactions, where the chip or contactless credential is read at the point of sale, generally qualify differently from card-not-present transactions such as online or keyed orders. CRS describes remote transactions as tending to have somewhat higher interchange than in-person transactions because the transaction carries different authentication and fraud risks. A merchant should therefore ask for separate treatment of retail, keyed and e-commerce volume instead of applying a storefront quote to every channel.
Merchant category and sales volume
Networks classify merchants by category, and schedules can vary for supermarkets, general retail, gas stations, quick-service restaurants and e-commerce. Volume and merchant size can affect both the schedule that applies and the markup an acquirer is willing to negotiate. The Federal Reserve Bank of Kansas City’s data page, updated in August 2026, displays schedules by category and merchant size. It cautions that published schedules do not necessarily equal issuer revenue and that some large merchants may receive lower fees than the published schedule.

How a transaction is submitted, what security information accompanies it and whether required data is captured can affect qualification under a network schedule. A transaction that lacks expected verification data may be priced differently from one submitted with complete, authenticated information.

Domestic versus cross-border use
Domestic and cross-border transactions can have different network and interchange treatment. A merchant serving international customers should request a quote that identifies those transactions rather than assuming its domestic effective rate applies worldwide.
Who pays, and who ultimately bears the cost?
The direct payer is the merchant
The business that accepts the card is contractually charged the MDR by its acquirer or financial institution. The merchant receives the sale proceeds net of that deduction. Calling the fee an “issuer fee” or saying that the shopper pays it at checkout confuses the parties: the issuer receives interchange, but the merchant pays the combined acceptance charge.
Consumers can bear part of it indirectly
A merchant may set prices with card acceptance in mind, spreading the cost across all sales. In a highly competitive market, however, raising prices can cost customers, so the business may absorb some or all of the expense. The result is not uniform: two merchants with the same card rate can pass through different amounts, and cash-paying customers may share a price that was influenced by card use.
Surcharges make the charge visible
Where state or local law and network rules permit, a merchant may add a credit-card surcharge and disclose it to the customer. Requirements can include advance notice, signage, receipt disclosure and limits tied to the merchant’s actual cost. Because the rules vary by jurisdiction and card program, a business must check the rules that apply where it operates before adding one. A surcharge is not evidence that every merchant is recovering its full MDR; many merchants use one price for all payment methods.

Credit cards and debit cards are regulated differently
Regulation II, implemented by the Federal Reserve, establishes standards for interchange fees on covered debit transactions and requires routing choices that prevent network exclusivity from blocking the prescribed options. Certain small issuers, government-administered programs and specified reloadable prepaid cards are exempt from the fee limitations.
Those provisions should not be described as a general cap on credit-card interchange. Credit and debit transactions can have different schedules and economics, and a debit rule does not automatically change the rate on a credit purchase. The Federal Reserve’s Regulation II information is dated May 17, 2024; anyone relying on a specific proposed or pending change should verify the current rule.

The Federal Reserve Bank of St. Louis reported that U.S. banks collected nearly $66 billion in interchange, or “swipe,” fees in 2025, up from $64 billion in 2024 and $52 billion in 2021. It said interchange represented approximately 11% of U.S. banks’ noninterest income in 2025. These are bank interchange figures, not the entire MDR that merchants pay: network assessments and acquirer or processor charges are outside that bank total.
Interchange supports issuer activities such as authorization, settlement, fraud protection and rewards programs, according to Julianne Baer of the St. Louis Fed. A large national total therefore describes revenue on the issuing side of the system; it does not tell an individual merchant what rate appears on its next statement.

Store cards can follow a different economic model
Private-label or retail-card programs may distribute economics differently from general-purpose cards. The Consumer Financial Protection Bureau has reported that a retailer can share in a retail-card program’s profits while also paying for rewards or discounts and, in some arrangements, helping fund promotional financing. Those contract-specific arrangements do not establish a standard rule for every store card, co-branded card or merchant. A retailer evaluating such a program must read its agreement rather than infer terms from ordinary network interchange.
How merchants should compare acceptance offers
The useful comparison is the complete cost of acceptance, not a headline interchange percentage. Request statements or quotes that separate the following items:
| Comparison point | Question to ask |
|---|---|
| Effective percentage | What percentage remains after interchange, network assessments and the provider’s markup are included? |
| Fixed amount | Is there a per-transaction charge in addition to the percentage, and how does it affect low-value sales? |
| Transaction type | Are in-person, keyed, card-not-present and cross-border transactions priced separately? |
| Volume and category | Does the quote reflect the merchant’s category and expected volume, and are there lower tiers at higher volume? |
| Negotiable markup | Which processing or acquirer charges can be reduced, and which network charges are pass-through amounts? |
| Service bundle | What account, gateway, equipment or other service fees are included, and which are billed separately? |
| Statement transparency | Will the merchant receive enough detail to reconcile the MDR with deposits and identify changes? |
Calculate an effective rate using a full statement: divide total card-acceptance charges by card sales for the same period, then examine how fixed charges change the result. Compare offers using the merchant’s actual mix of ticket sizes, card products and sales channels. A provider that advertises a low percentage can cost more if its fixed charge or separate service fees are high.
Quick Recap
Common misconceptions to avoid
- “The merchant pays interchange directly.” The merchant pays its acquirer’s MDR; interchange is one component that the network routes to the issuer.
- “Swipe fees apply only to a physical swipe.” The term covers card-acceptance economics across chip, contactless and remote transactions.
- “Every merchant passes the exact fee to customers.” Prices, competition and customer sensitivity determine how much is recovered.
- “A debit interchange cap also caps credit cards.” Regulation II addresses covered debit transactions and routing, not credit-card interchange generally.
- “A published schedule is the merchant’s final price.” Network schedules omit or do not determine every acquirer, processor and service charge, and large merchants may negotiate different terms.
