The merchant pays the transaction fee, not you

When you swipe or tap a credit card at checkout, the business pays a fee to process that transaction. You do not see this charge on your receipt or credit card statement — it comes out of the merchant's account, usually within one to three business days. The fee typically ranges from 1.5% to 3.5% of the transaction amount, though it varies by card type, the merchant's processing agreement, and the payment processor they use.

This arrangement exists because credit card networks (Visa, Mastercard, American Express, Discover) set the rules and rates. The merchant's bank, your bank, and the card network all take a cut of that fee. The merchant absorbs the total cost as a business expense, similar to rent or utilities.

Key Takeaways

  • Merchants pay transaction fees directly to their payment processor; these fees never appear on your credit card bill.
  • Transaction fees typically run 1.5% to 3.5% of the purchase amount and vary based on the card type and the merchant's processing agreement.
  • Some merchants pass the cost along by charging higher prices, offering discounts for cash, or adding a surcharge — which is legal in most states but subject to state-specific rules.
  • Debit cards, prepaid cards, and some business cards have different fee structures than standard credit cards.

How the fee gets split among banks and networks

The transaction fee is divided among three parties. Your card issuer (the bank that gave you the card) receives the largest share, called the interchange fee, which typically makes up 1% to 2% of the transaction. The card network (Visa, Mastercard, etc.) takes a smaller percentage. The merchant's acquiring bank takes the remainder and handles the actual deposit to the merchant's account.

Interchange rates are set by the card networks and differ by card type. A rewards credit card often carries a higher interchange fee than a basic card, because the issuer is funding your cash back or points. A business card or corporate card may have a different rate structure altogether. Debit cards have lower interchange fees by law — the Durbin Amendment caps debit interchange at roughly 0.05% plus a small fixed fee.

The merchant's acquiring bank may also charge a separate monthly fee, a per-transaction flat fee, or a combination of both. These terms are negotiated when the merchant sets up their payment processing account.

When merchants pass the cost to you

Most merchants absorb transaction fees as a cost of doing business and do not charge you extra. However, some businesses — particularly small retailers, restaurants, and service providers — pass the cost along to customers. This can happen in three ways: higher menu or shelf prices across the board, a discount for paying with cash, or a surcharge added to credit card purchases.

Surcharges are legal in most states, but the rules vary. Some states cap the surcharge at a specific percentage (often 4%, matching the average transaction fee). A few states ban surcharges entirely on credit cards, though they may allow them on debit cards. California, New York, and Texas allow surcharges but require the merchant to disclose them clearly at the point of sale and on receipts. If you see a surcharge, check your state's rules — your state attorney general's office or consumer protection agency publishes this information.

Merchants cannot legally surcharge American Express in some states, because American Express's merchant agreements historically prohibited it. This rule has loosened in recent years, but varies by state and by Amex's current terms.

Why different cards have different fees

Not all credit cards cost merchants the same amount to process. A rewards card with 2% cash back typically has a higher interchange fee than a basic card with no rewards, because the issuer needs to fund your rewards. Premium cards (those with annual fees) often have even higher interchange rates. Business cards, corporate cards, and commercial cards have their own fee schedules, which are sometimes higher than consumer cards.

Debit cards are cheaper for merchants to process than credit cards, which is why some businesses offer a discount for debit or cash. Prepaid cards fall somewhere in between, depending on the card issuer's agreement with the payment network.

The merchant does not choose these rates — they are set by the card networks and the merchant's acquiring bank. A small business cannot negotiate a lower Visa interchange rate; they can only choose which acquiring bank to work with, and different banks may offer slightly different terms.

What happens with online and phone orders

Online and phone transactions carry higher fees than in-person card-present transactions, because the fraud risk is higher. A "card-not-present" transaction typically costs the merchant 2.5% to 3.5%, while a swiped or tapped card might cost 1.5% to 2.5%. This is why some online retailers charge more than brick-and-mortar stores for the same item.

Merchants can reduce this risk — and sometimes lower their fees — by using address verification, CVV checks, and 3D Secure authentication. These tools do not eliminate the higher rate, but they may help a merchant negotiate better terms with their acquiring bank.

International and currency conversion fees

When you use a credit card abroad or make a purchase in a foreign currency, additional fees apply. Your card issuer charges a foreign transaction fee (typically 1% to 3%) and may also mark up the exchange rate. The merchant's bank also charges the merchant a fee for processing a cross-border transaction. You see the issuer's fee on your statement; the merchant absorbs their bank's fee.

Some credit cards waive foreign transaction fees for cardholders, but the merchant still pays their processing fee. This is one reason travel rewards cards often have higher annual fees — the issuer expects to pay more in interchange and foreign transaction costs.

Frequently Asked Questions

Can a merchant charge me extra for using a credit card?

Yes, in most states. A merchant can add a surcharge to credit card purchases, though the amount and disclosure rules vary by state. Some states cap surcharges at 4% or ban them entirely. Check your state's attorney general website to learn the rules where you live.

Why do some stores offer a discount for cash?

Because the merchant saves money when you pay cash — they avoid the 1.5% to 3.5% transaction fee. The discount they offer is usually smaller than the fee they save, so it benefits both of you. This is legal in all states.

Do debit cards have lower fees than credit cards?

Yes. Federal law caps debit card interchange at roughly 0.05% plus a small fixed fee per transaction. Credit cards typically cost merchants 1.5% to 3.5%. This is why some businesses prefer debit payments.

Who sets the transaction fee rates?

The card networks (Visa, Mastercard, American Express, Discover) set interchange rates. Your card issuer and the merchant's acquiring bank negotiate their own fees on top of that. Individual merchants cannot negotiate the interchange rate itself.

Does my rewards cash back come from the transaction fee?

Partially. Your card issuer funds your rewards from the interchange fee they receive, but they also use other revenue sources like annual fees and interest charges. The higher the interchange fee, the more the issuer can afford to pay in rewards.
