What Is Interchange? The Fee Behind Every Card Swipe, Explained

Who actually gets the interchange money?

Follow one $100 restaurant tab paid on a Chase Visa card. Somewhere between $1.50 and $2.50 of it never reaches the restaurant — and the biggest slice of that goes somewhere most owners never suspect.

Interchange is paid by the merchant's bank to the customer's issuing bank — the bank whose name is on the card. Not to Visa. Not to your processor. Chase, Capital One, Bank of America, your local credit union: whoever issued the card collects interchange on every swipe, dip, and tap. Your processor collects it from you as part of your processing fees and passes it through.

That surprises almost everyone, so here's the full split on that $100 tab under a typical setup:

• Interchange (roughly $1.50–$2.20): goes to the issuing bank. This funds the card's rewards program, fraud losses, the interest-free float between purchase and statement date, and the issuer's profit.
• Assessments (roughly $0.13–$0.15): go to the card network — Visa or Mastercard — for running the rails. This is the networks' actual revenue, and it's tiny compared to interchange.
• Processor markup (whatever's left): goes to your processor. This is the only layer any processor controls, and the only layer you can negotiate. We break the full stack down in our guide to what processing should cost.

Why does this arrangement exist at all? Because issuing banks take the risk. When a cardholder doesn't pay their bill, the issuer eats it. When a stolen card gets used, the issuer usually fronts the fraud loss. Interchange is the payment system's way of compensating the bank that extends the credit and carries the risk — and, increasingly, the way issuers fund the points, miles, and cash-back offers that keep customers reaching for their most expensive cards.

How are interchange rates set?

Visa, Mastercard, and Discover each publish a schedule of interchange categories — hundreds of them per network — and every transaction lands in exactly one category based on a handful of variables:

• Card type: debit vs. credit, consumer vs. commercial, standard vs. rewards vs. premium rewards.
• Entry method: tapped, dipped, swiped, keyed, or ecommerce.
• Merchant category: supermarkets, restaurants, fuel, charities, and utilities have their own special categories, some with capped dollar amounts.
• Data quality and timing: whether the transaction settled promptly and carried the required data fields (address verification, invoice numbers, tax amounts).

The networks update these tables on a set cycle — historically each April and October — and adjustments arrive without ceremony. A category moves a few basis points, a new category appears for premium cards, and your cost quietly shifts even though your agreement never changed. This is one reason your effective rate can drift upward while you "didn't change anything."

The rates themselves are the networks' attempt to balance a two-sided market. Set interchange too low and banks stop issuing cards or gut the rewards that drive spending. Set it too high and merchants revolt, surcharge, or steer customers to cash — which is exactly what more of them are doing through programs like dual pricing, surcharging, and cash discounts.

Where can I see the actual rates?

This is the part of the industry that stays hidden only because nobody looks: Visa and Mastercard publish their complete U.S. interchange tables on their own websites, free, for anyone to read. Search "Visa USA interchange reimbursement fees" or "Mastercard interchange rates" and you'll find the current PDFs.

A few honest reference points from the general shape of those tables, so you know the terrain:

Treat these as ranges, not gospel — the real tables run hundreds of rows and change twice a year. But the shape is the lesson: the spread between the cheapest and most expensive interchange category is nearly three full percentage points. On identical $100 sales, one card can cost you 27¢ and another can cost you $3. Your "processing rate" is really an average over your card mix, which is why two businesses with the same processor and same pricing can pay very different effective rates.

Why does card-present cost less than card-not-present?

One-line definition worth remembering: a card-present transaction is one where the physical card interacts with your terminal — tap, dip, or swipe — while a card-not-present (CNP) transaction is keyed, phoned, or typed into a website.

Interchange prices risk, and the networks' data says CNP transactions get disputed and defrauded far more often. When a chip card is dipped or tapped, the chip cryptographically proves the card is genuine. When a number is typed into a checkout page or keyed into a terminal, nothing proves anything — so the issuing bank charges more to carry that risk. The premium typically runs 0.30%–0.80% for the same card, and it stacks with tighter downgrade rules.

Practical consequences for a Dallas storefront:

• If your counter staff key in cards because "the chip reader is slow," you're paying CNP prices for card-present sales — plus likely downgrades for skipping address verification.
• If you invoice by email, every payment is CNP by nature. That's fine — it's the honest cost of the channel — but it's also why big-ticket invoicing businesses should look hard at ACH as an alternative, where the same $5,000 invoice costs dollars instead of percent.
• Modern terminals that default to tap and dip aren't a luxury; they're an interchange qualification tool.

Debit interchange: the Durbin divide

Debit is where interchange gets genuinely strange, and where flat-rate processors make their best margin. The Durbin Amendment (part of the 2010 Dodd-Frank Act) capped debit interchange for banks with over $10 billion in assets at 0.05% + 21¢, plus a 1¢ fraud-prevention adjustment for qualifying issuers — call it 22¢ on most transactions.

That created two classes of debit card that look identical in a customer's hand:

• Regulated debit — issued by big banks (Chase, Wells Fargo, Bank of America). A $50 sale costs about 24–25 cents in interchange. Not percent. Cents.
• Exempt (unregulated) debit — issued by community banks and credit unions under the $10B threshold. These still ride the network tables, typically 0.70%–1.00% + 15–22¢ card-present.

Now do the math on flat-rate pricing. A processor charging 2.6% + 10¢ on a $50 regulated-debit sale collects $1.40 against a wholesale cost of about 32 cents including assessments. The margin on that one debit transaction is over 300% — and debit is 30–50% of card volume at many quick-service and retail businesses. If your customers skew debit-heavy, flat-rate pricing is quietly your most expensive line item, and interchange-plus pricing returns most of that spread to you. Your statement will show the split if you know how to read it.

Why rewards and corporate cards cost you more

Every airline mile your customer earns is funded by somebody, and that somebody is you. Rewards interchange is the mechanism that converts merchant fees into cardholder perks: the networks assign premium cards — Visa Signature and Infinite, Mastercard World and World Elite — to higher interchange tiers, and issuers use the extra revenue to bankroll points, lounges, and cash back.

The gap is material. A standard consumer credit card at a Texas retail counter might carry interchange around 1.5%; the same sale on a top-tier travel rewards card can run 2.1%–2.4%; a corporate purchasing card keyed in with no supporting data can clear 2.9%. Merchants can't refuse premium cards selectively — honor-all-cards rules require you to take every card in a brand's credit class if you take any — so your only levers are:

• Qualification: make sure every transaction hits its best available category (hardware, settlement, data — see the next two sections).
• Pricing model: interchange-plus so premium-card costs pass through visibly instead of funding a padded tier.
• Cost-shifting: a compliant dual pricing program, which moves the cost of card acceptance into the card price rather than your margin — the biggest single lever for most merchants.

One trend worth knowing: premium-card issuance has grown steadily for a decade, which means the average interchange on a typical merchant's card mix drifts upward year over year even when the published tables barely move. If your effective rate creeps up 5–10 basis points a year with no other change, card mix is often the quiet culprit.

Downgrades: the silent interchange tax

Here's the one-line definition: a downgrade is when a transaction fails to meet the requirements of its best interchange category and gets billed at a more expensive fallback category instead.

Each favorable category has fine print — the transaction must settle within a set window (usually one to two days), carry a valid authorization, match certain data fields, and arrive via an approved entry method. Miss any requirement and the networks reroute the transaction to a fallback like Visa's EIRF (Electronic Interchange Reimbursement Fee) or, worse, Standard — categories that can cost 0.5%–1.5% more than the rate the sale should have earned.

Common causes we find on Dallas–Fort Worth merchants' statements:

• Late settlement: batches closed manually and forgotten over a weekend. Fix: auto-close every night.
• Missing AVS: keyed transactions without address verification. Fix: turn AVS on and enter the ZIP code.
• No tax or customer-code data on commercial cards: corporate cards billed at top rates for want of a few fields. Fix: level 2/3 data (next section).
• Stale authorizations: auths captured days later, common in service businesses that pre-auth. Fix: reauthorize or settle within the window.

The insidious part is where downgrades hide: inside the interchange section of your statement, labeled with category names nobody recognizes. They look like a cost of doing business. They're actually a configuration error — usually your processor's — compounding monthly.

Level 2 and level 3 data: the B2B discount

The networks charge less when a transaction carries more data — because richer data means fewer disputes and easier reconciliation for the corporate buyers using those cards. That's the whole idea behind processing levels:

• Level 1 is a normal consumer transaction: amount, date, merchant name.
• Level 2 adds fields like sales tax amount, customer code, and merchant ZIP — and can shave roughly 0.25%–0.50% off commercial-card interchange.
• Level 3 adds line-item detail — quantities, item descriptions, unit costs, freight — and can bring total savings on eligible corporate and purchasing cards to roughly 0.50%–1.00%.

If you sell to businesses — a distributor in the Design District, a commercial HVAC contractor, a wholesale operation off I-35 — corporate cards may be a third of your volume, and every one of them is billing at top-tier interchange unless your gateway is passing enhanced data. The good news: modern gateways can auto-populate most level 2/3 fields, so this is a setup task, not a per-sale chore. It's one of the first things we check in a statement review, because it's pure savings with no change to how you sell. It pairs naturally with the rest of the tactics in our guide to lowering processing costs.

The "we have lower interchange" lie

Now you're equipped for the most common lie in payment sales. A rep says some version of: "We're a direct processor, so we get better interchange rates than the competition."

Here is the plain truth: interchange is set by the card networks and is identical for every processor in the United States. The five-person ISO in Plano and the largest bank processor in the country pay the same published rates to the same issuing banks on the same transactions. Nobody has a volume deal on interchange. Nobody is "direct" in a way that changes the wholesale price. When Visa updates its table in April, it updates for everyone on the same day.

What a processor can legitimately do — and what a good one does — is affect which categories your transactions qualify for:

• Configure terminals and gateways so tap/dip transactions hit card-present rates and keyed ones carry AVS;
• Auto-settle batches inside the qualification window;
• Pass level 2/3 data on commercial cards;
• Assign the correct merchant category code, which controls which special-industry tables you ride.

That's optimization, and it's real money. But it's not "lower interchange" — it's correct interchange. A rep who can't or won't make that distinction is telling you how the rest of the relationship will go. It's the same species of misdirection we catalog in our merchant agreement red flags guide: true statements arranged to create false impressions.
