Restaurant card processing fees explained

Card processing is charged on almost every sale, so over the life of a POS contract it can cost more than the software. It is also the part of the price that is hardest to compare. This guide explains what you are actually paying for, how the common pricing models differ, and what to ask before you sign.

Where the money goes

Visa describes interchange as "transfer fees between acquiring banks and issuing banks for each Visa card transaction". You never pay it directly; it is built into whatever your processor charges you. The part you can negotiate, or compare, is the processor's markup and its monthly fees.

What interchange looks like for restaurants

Visa publishes its U.S. interchange rates. In the table effective April 18, 2026, rates for restaurants include:

Source: Visa USA Interchange Reimbursement Fees, rates effective April 18, 2026. Mastercard and other networks publish their own tables, and rates change from time to time.

Three things follow from that table:

• Rewards cards cost more to accept than basic cards.
• Online and keyed cards cost more than cards tapped or dipped in person.
• Debit can be much cheaper, especially debit cards from large banks whose debit interchange is capped.

Your card mix, which no one but you knows, drives your real cost.

The three common pricing models

What POS vendors publish

Many POS vendors sell processing as part of the system, usually at flat rates. These are the rates each one publishes, checked October 1, 2026:

Compare those flat rates with the Visa interchange table above: a flat in-person rate of 2.3% to 2.8% sits on top of interchange that runs from about 0.9% on a $25 ticket for capped debit cards (0.05% + $0.21) to 2.60% for rewards credit cards. On a flat rate, the processor keeps more on debit and basic cards and less on rewards cards. That is why your card mix decides which model is cheaper for you.

Compare offers with your own numbers

A headline rate tells you little on its own. Ask each vendor for a written estimate using:

• Your monthly card volume and number of transactions (average ticket).
• Your split between in-person, online and keyed payments.
• Your rough split between credit and debit.

Then compare the effective rate: total monthly processing cost divided by total card sales.

A restaurant takes $40,000 a month in card sales over 1,600 transactions (a $25 average ticket). At a flat 2.6% + $0.15 in person, processing costs $1,040 + $240 = $1,280 a month, an effective rate of 3.2%. An offer that saves 0.3 percentage points on the effective rate saves $120 a month, or $4,320 over three years.

Fees beyond the rate

Ask for every fee in writing:

• Monthly account, statement or gateway fees.
• PCI compliance or "non-compliance" fees.
• Chargeback fees.
• Fees for next-day or same-day deposits.
• Early-termination fees and how long the agreement runs.
• Whether the POS hardware works with another processor if you leave.

Surcharges and cash discounts

Some restaurants add a surcharge to card payments. Card networks set rules for this. Visa's merchant guidance says surcharges must be limited to credit cards, "debit cards and prepaid cards cannot be surcharged", capped at your merchant discount rate or 3%, whichever is lower, and disclosed at the point of entry, at the point of sale and on every receipt. Visa also requires that "merchants must notify their acquirer 30 days before they begin surcharging."

Some states restrict or prohibit surcharging. Visa's own guidance names several but says its list "should not be relied on as authoritative information or legal advice." Check your state's law and your processor's rules before adding a surcharge, and treat this section as a pointer, not legal advice.

Tips on cards

When a guest adds a tip after the card is authorized, the final amount differs from the authorization. Visa's guide for restaurant merchants says restaurants, bars and fast-food restaurants may add up to 20% to the authorization amount without liability for authorization-related disputes. That guide dates from 2018, so ask your processor what applies to you now. For bar tabs, see the bar and nightclub guide.

Card security (PCI DSS)

The PCI Data Security Standard applies to merchants and every other business that stores, processes or transmits cardholder data. Your POS vendor and processor handle much of it, but not all. Ask what they cover, what you must do (often an annual questionnaire), and whether they charge a fee for it.

1099-K reporting

Card payments are reported to the IRS on Form 1099-K. The IRS says that if customers pay you directly by credit, debit or gift card, "you'll get a Form 1099-K from your payment card processor no matter how many payments you got or how much they were for." The $20,000 and 200-transaction threshold applies to payment apps and online marketplaces, not to card processors. Your sales records in the POS should match those forms; ask your accountant how this applies to you.

Questions to ask before you sign

1. Is this flat-rate, interchange-plus or tiered pricing?
2. What is my estimated effective rate at my volume and card mix?
3. What are all the monthly and annual fees?
4. How long is the agreement, and what does it cost to leave early?
5. Must I use your processing to use the POS? Does the hardware work with another processor?
6. When do deposits reach my bank account, and does faster deposit cost extra?
