Credit card processing fees, explained for owners

Every card fee you pay is split 3 ways: the bank that issued the card, the card network, and your processor. The issuer's share is set by published tables, not by your processor. The processor's share is where you have room to compare and negotiate.

This guide explains the 3 parts of a card fee, why the same $400 job can cost you very different amounts depending on the card, and how to work out your real rate from one monthly statement.

The 3 parts of every card fee

Interchange is paid to the bank that issued your customer's card. The card networks set it. Visa describes its interchange fees as transfer fees between the merchant's bank and the card issuer, and says merchants do not pay them directly.^[1]

Instead, Visa says, merchants pay a "merchant discount" to their own financial institution, typically a percentage of each transaction, and that rate bundles interchange together with the other processing services they buy.^[1] In plain terms, your processor collects the whole fee and passes interchange along.

• Interchange: goes to the card issuer. Set by the network's published schedule.
• Network fees: go to the card network itself for running the system.
• Processor markup: goes to the company that handles your payments. This is the part you can shop around on.

Why the card type changes the cost

Interchange is not one rate. Visa's US schedule, effective April 18, 2026, runs to dozens of pages, with different rates by card type, business type, sale size, and whether the card was in front of you.^[2] Premium rewards cards cost the most. Debit cards from large banks cost the least.

For regulated debit, Visa adds 1 cent for issuers that certify they meet fraud prevention standards.^[2] Card-not-present rates are also adjusted for some security methods, such as tokenized card details.^[2] The bottom line is the same: a keyed-in or online payment usually costs a little more than a card tapped in person.

The federal cap on debit cards

Debit is cheap for a reason. Under the federal rule known as Regulation II, a large bank's debit interchange can be no more than 21 cents plus 0.05% of the sale.^[3] A bank that meets the fraud prevention standards can add up to 1 cent per transaction.^[4] The cap applies to card issuers with $10 billion or more in assets.^[5]

The Federal Reserve's own data shows the gap. In 2023 the average debit interchange fee was $0.23 per transaction for covered banks, or 0.47% of the sale. For exempt banks it was $0.52, or 1.21%.^[6]

This rule is in flux. In October 2023 the Federal Reserve proposed lowering the cap, and that proposal had not taken effect when we checked.^[5] In August 2025 a federal court in North Dakota ruled that Regulation II exceeded the Board's authority and vacated it, but stayed its own ruling while any appeal runs, so interchange would not become unregulated.^[7] As of this writing the cap still applies. Check for changes before you rely on it.

The same rule says issuers must enable at least 2 unaffiliated networks on each debit card, and may not stop merchants from choosing how a debit payment is routed.^[8] Ask your processor whether it routes debit to the cheaper network.

What a $400 job costs to accept

Here is an illustration, not data from a real business. A cleaning company takes $400 for a job, card present, and suppose the Services rates in the table apply.

• Traditional rewards credit card: 1.70% of $400 is $6.80, plus $0.10, so $6.90 in interchange.
• Visa Infinite card: 2.30% of $400 is $9.20, plus $0.10, so $9.30.
• Debit card from a large bank: 0.05% of $400 is $0.20, plus $0.21 and the 1 cent fraud adjustment, so $0.42.

Network fees and your processor's markup sit on top of each. On a flat-rate plan you pay the same percentage whichever card arrives, so debit-heavy businesses may pay more than the underlying cost.

How processors price it

Processors package these costs in a few common ways. Knowing which one you have tells you what to compare.

• Flat rate: one percentage and a fixed amount per sale, whatever the card. Easy to predict, and you pay the same for cheap debit as for premium credit.
• Interchange plus: the actual interchange and network fees, passed through, plus a stated markup. Harder to read, but the markup is visible.
• Tiered: sales sorted into buckets such as "qualified" and "non-qualified" at different rates. The processor decides the buckets, which makes comparison hard.

Work out your effective rate in 10 minutes

1. Take last month's statement. Find total card sales and total fees, including monthly and per-transaction charges.
2. Divide fees by sales. That is your effective rate. It is the only number worth comparing between offers.
3. Check the card mix. Note how much came from debit versus credit, and from keyed-in or online versus tapped cards.
4. List fixed fees. Monthly minimums, statement fees, PCI fees, and equipment rental all count.
5. Get 2 quotes on the same statement. Ask each processor what that exact month would have cost.

Ways to pay less without annoying customers

Take cards in person where you can. Tapped and dipped cards generally qualify for lower rates than keyed-in numbers.^[2] With tap to pay on the mobile app, a technician can take a contactless payment at the job, and it is recorded against the customer.

Send a link instead of reading card numbers over the phone. A payment link the customer opens on their own phone avoids keying in their card. Our guide to text-to-pay covers how to word the message.

Keep your processor if the rate is good. In Pinn.Media CRM you connect the card processor you already use for invoices, estimates, and payment links. Your processor charges its own fees, separate from your plan, so the comparison work above still matters.

Know the rules before passing fees on. Some businesses add a card fee to the customer's payment, and our payments tools let you choose whether to. Card network rules and state laws limit how that works, so check them first. We cover them in a separate guide.

Trades feel card costs on every large invoice. See how a home services business and a professional services firm send invoices and take payment in one place.
