Average Credit Card Processing Fees and Costs in America

U.S. merchants paid $198.25 billion in credit and debit card processing fees in 2025, a new annual record, according to Merchant Payments Coalition, citing data from the Nilson Report. Processing fees paid by merchants have more than tripled from $62.1 billion in 2009.

Processing fees -- particularly from credit cards -- are among the largest operating costs most merchants face outside of labor. The fees flow through three layers: interchange (paid to the card-issuing bank), assessment fees (paid to the payment network), and a markup charged by the payment processor. The actual rate a merchant pays depends on the card network, card type, merchant category, and whether the card is physically present at the point of sale.

The tables below show current rates from Visa, Mastercard, and Discover's published 2026 interchange schedules, Federal Reserve data on regulated debit interchange, and weighted effective rate averages from payment processor Helcim.

Total swipe fees

Visa and Mastercard together account for more than 80% of U.S. credit card transaction volume, and their average combined credit card interchange rate reached 2.36% in 2025, up from 2.02% in 2010, according to the Merchants Payments Coalition.

Interchange rates have risen gradually as more Americans have switched to premium and rewards credit cards, which carry higher interchange fees than standard cards. The Merchant Payments Coalition estimates that rising swipe fees have cost more than $1,200 per average American family annually, through a combination of higher retail prices and direct surcharges.

Average credit card processing fees by network

The figures a merchant actually sees on a processing statement are higher than interchange alone.

The table below shows all-in effective rates under interchange-plus pricing, which stacks interchange, network assessment fees, and a processor markup into a single per-transaction cost.

For most merchants, this is the most useful benchmark for what card acceptance costs in practice. Merchants using flat-rate processors will typically pay more; those negotiating subscription-model contracts may pay less at higher volumes.

The gap between in-person and card-not-present rates reflects higher fraud risk for online transactions. Card-not-present fraud accounted for 54.3% of all debit card fraud losses in 2023, according to the Federal Reserve Board's 2023 Interchange Fee Revenue Report.

Credit card interchange fee rates, by network

Interchange is the largest component of a processing fee. It flows from the merchant's bank (the acquirer) to the cardholder's bank (the issuer) and is set by the payment network. The primary factors that determine a transaction's interchange rate are the merchant category code (MCC), the card tier (standard, rewards, premium), and whether the card is physically present.

Visa Consumer Credit (effective April 18, 2026)

Discover Consumer Credit

Card tier -- which reflects card type, such as those that offer cash back, travel points, or other perks -- is the biggest single variable within any network. A World Elite Mastercard at a standard retail merchant carries a Merit I rate of 2.60% plus $0.10, while a Core Mastercard at the same merchant qualifies for 1.95% plus $0.10.

When a transaction fails to meet the data or authorization requirements for a qualified rate, both Visa and Mastercard fall back to their Standard (non-qualifying) rate of 3.15% plus $0.10, the highest consumer credit rate either network publishes.

Assessment fees by payment network

Assessment fees are charged by the payment network itself, separate from the interchange fee that goes to the issuing bank. They are a much smaller component of total processing cost.

Discover publishes its assessment fee components directly in its interchange schedule. For Visa and Mastercard, assessment rates are not broken out in a single published figure the way Discover does; industry data places them at approximately 0.14% to 0.165% of transaction value, with additional per-transaction flat fees for specific services.

The Federal Reserve's 2023 Interchange Fee Revenue Report found that total network fees across all U.S. debit card transactions reached $12.95 billion, or $0.129 per transaction on average. Acquirers and merchants paid 64.9% of those network fees, a share that has risen steadily from 44.3% in 2009, while issuers paid the remainder.

Payment processor pricing models

Interchange and assessment fees are non-negotiable and set by the networks. What merchants can influence is the pricing model their payment processor uses to pass those costs along.

Under interchange-plus, every transaction's cost is fully visible: the interchange rate, the assessment fee, and the processor markup appear as separate line items.

Under flat-rate and tiered models, those components are bundled, which makes the effective rate easier to predict but harder to verify.

At higher sales volumes, the monthly fee charged by subscription-model processors typically more than pays for itself in reduced per-transaction costs.

Debit card interchange and the Durbin Amendment

Debit card interchange is governed by a separate regulatory framework. The Durbin Amendment to the Dodd-Frank Act, implemented through the Federal Reserve's Regulation II, caps interchange fees for debit card transactions at financial institutions with $10 billion or more in assets.

The cap is $0.21 plus 5 basis points of the transaction value, with an additional $0.01 fraud-prevention adjustment available to qualifying issuers.

According to the Federal Reserve's 2023 Interchange Fee Revenue Report, published in December 2025, the average interchange fee for covered debit transactions was $0.22 for dual-message networks (traditionally signature-based) and $0.24 for single-message networks (traditionally PIN-based). Both figures have remained essentially flat since Regulation II took effect in the fourth quarter of 2011.

Exempt issuers, those with under $10 billion in consolidated assets, averaged $0.52 per transaction in 2023, more than double the covered-issuer average. In 2023, 80.1% of covered issuers had per-transaction costs at or below the Regulation II cap, and those issuers represented 99.2% of all covered transactions.

Debit card processing costs merchants considerably less than credit, which is why merchants at high debit-card volume benefit most from the cap and why some merchants charge a surcharge specifically for credit card use.

Total U.S. debit and general-use prepaid card transaction volume reached 100.7 billion transactions in 2023, valued at $4.7 trillion, growing at an average annual rate of 4.6% from 2021 to 2023, according to the Federal Reserve.

How much are credit card processing fees for small businesses?

For merchants without the volume to qualify for performance-tier interchange rates, the effective cost of accepting credit cards typically falls within the following ranges, based on the published 2026 network schedules and Helcim's weighted effective rate data.

The card type the customer presents, not the merchant's processor choice, determines where within these ranges a given transaction lands. A merchant that accepts premium rewards cards, which are common among higher-income cardholders, will consistently pay toward the top of those ranges.

What credit card swipe fee data shows

Credit card processing fees have risen every year since 2009, and the 2025 record of $198.25 billion reflects both growth in card spending volume and a slow, steady increase in the average interchange rate merchants pay. The average Visa and Mastercard credit card rate has climbed from 2.02% in 2010 to 2.36% in 2025, a 17% increase over 15 years that compounds across billions of transactions.

For businesses, choosing a payment processor matters less than understanding which cards customers actually use. A regulated debit transaction costs a merchant roughly $0.22 to $0.24 flat. A standard credit card runs 1.43% to 1.95% plus a small flat fee. A premium rewards card -- the kind with travel points or cash-back bonuses -- can push that to 2.60% or higher, at the same register, with the same processor. Merchants with a high share of premium card customers will consistently pay toward the top of any published rate range.

Legislative pressure on swipe fees has intensified. The Credit Card Competition Act, endorsed by President Trump earlier in 2026, would require banks with $100 billion or more in assets to enable credit card routing over at least two unaffiliated networks, introducing competition that the Merchants Payments Coalition estimates could save merchants and consumers more than $17 billion annually. The outcome of that legislation could influence the trajectory of credit card swipe fees for years to come.
