Apex Pay - Card Fees, Decoded
What Is Interchange? The Fee Behind Every Card Swipe, Explained
Interchange is the base fee your business pays every time a customer pays by card. It's set by the card networks (Visa, Mastercard, Discover, American Express) and paid to the bank that issued your customer's card. It is the largest, non-negotiable slice of your processing bill - typically 1.2%-3.3% plus a small per-transaction fee - which is exactly why understanding it is the first step to paying less overall.
What is interchange, exactly?
Interchange is a wholesale fee, baked into every card transaction, that moves from your bank to your customer's bank. When someone taps a card at your counter, their card-issuing bank (the "issuer") fronts the money and takes on the risk of fraud and non-payment. Interchange is how that issuer gets compensated. Visa and Mastercard don't keep this fee - they set the rates and route the money to issuers to keep banks issuing cards and cardholders spending.
Think of interchange as the cost of goods for accepting cards. Your processor can mark it up, bundle it, or hide it, but no processor can make it disappear. Every legitimate quote you'll ever get is interchange plus something.
Who actually gets the money when a card is swiped?
A single swipe touches four parties in about two seconds. Interchange is just one of the fees created along the way:
- The issuing bank - your customer's bank (Chase, Capital One, a local credit union). It collects the interchange fee.
- The card network - Visa, Mastercard, Discover, or Amex. It sets interchange and charges its own smaller assessment fee.
- The acquiring bank / processor - your side of the transaction. It adds a markup for its service.
- The merchant - you. You pay all three of the above out of every sale.
So the "3% card fee" a business owner grumbles about is really three stacked fees. Interchange is the biggest of them - usually 70%-90% of the total - and it's the one most owners never see itemized.
Interchange vs. assessments vs. markup - what's the difference?
These three components make up nearly every processing statement. Only one of them is actually negotiable.
| Fee | Paid to | Typical size | Negotiable? |
|---|---|---|---|
| Interchange | Issuing bank | ~1.2%-3.3% + $0.05-$0.22 | No - fixed by the network |
| Assessment | Card network (Visa/MC) | ~0.13%-0.15% | No - fixed by the network |
| Processor markup | Your processor | Varies widely | Yes - this is your lever |
This is the single most useful thing to internalize: you cannot negotiate interchange, but you can negotiate the markup on top of it. A pricing model called interchange-plus shows all three lines separately, so you can see the true wholesale cost and exactly what your processor is charging above it. Flat-rate pricing (a clean "2.9% + 30 cents") hides the seam - convenient, but you never learn where your money actually goes.
Why does one card cost more to accept than another?
Interchange isn't a single number - it's hundreds of published rates, and the network picks one for each transaction based on a handful of factors. The big ones:
- Card type. A basic debit card is cheap. A premium travel-rewards or corporate card is expensive - because the points funding your customer's airline miles come partly out of interchange.
- How the card is entered. A physically dipped, tapped, or EMV chip transaction ("card-present") earns a lower rate than a keyed-in or online one ("card-not-present"), because it carries less fraud risk.
- Your Merchant Category Code (MCC). Networks assign different rates to grocery, fuel, restaurants, charities, and B2B. Your industry code directly affects your cost.
- Data level. B2B and government transactions that pass richer "Level 2" and "Level 3" data (invoice numbers, tax amounts, line items) qualify for meaningfully lower interchange.
- Regulation. Under the U.S. Durbin Amendment, debit cards from banks with over $10 billion in assets are capped at roughly $0.21 + 0.05% - a fraction of unregulated credit interchange.
Interchange rates are refreshed by the networks twice a year, typically in April and October. The number you paid last spring is not necessarily the number you're paying today.
Can you actually lower what you pay in interchange?
Answer-first: you can't change the rate the network publishes, but you can qualify for cheaper rates and strip out markup. That distinction is where real savings live.
- Switch to interchange-plus pricing so you can see - and negotiate - the markup instead of paying a padded flat rate.
- Keep transactions card-present when possible; tapped and dipped cards beat keyed-in ones on rate every time.
- Pass Level 2/Level 3 data if you sell B2B - it can move a transaction into a lower interchange category automatically.
- Use address verification (AVS) on card-not-present sales to avoid downgrades into pricey non-qualified rates.
- Batch out daily. Letting authorizations settle late can bump transactions to a higher tier.
Illustrative sample - not a client outcome. On a $100 in-person sale with a consumer rewards Visa credit card, interchange might run about $1.65 (1.65% + $0.10), the network assessment about $0.14, and a transparent processor markup about $0.30 - roughly $2.09 total. Figures use published network rate ranges for illustration only; your actual rates depend on card type, entry method, and MCC.
What's changing with interchange in 2026?
Interchange is under more legal and regulatory pressure than at any point in its history. A long-running U.S. antitrust settlement between Visa, Mastercard, and millions of merchants received renewed court attention in 2026, with proposed terms that would trim average credit interchange and cap certain consumer-card rates for a set period. Separately, a 2025 federal ruling challenged the Federal Reserve's debit interchange cap, though it was stayed pending appeal. None of this is finalized, and none of it changes the fundamentals: interchange is still the base cost of card acceptance, and transparency is still your best defense. Treat any "the fees are dropping" pitch with healthy skepticism until it shows on your statement.
Frequently asked questions
Who sets interchange fees?
The card networks - Visa, Mastercard, Discover, and American Express - publish and set interchange rates. The money itself is collected by the bank that issued your customer's card, not by the network and not by your processor.
Is interchange the same as my total processing fee?
No. Your total fee is interchange plus a network assessment plus your processor's markup. Interchange is the largest piece, but it's the markup - the smallest and most variable piece - that you can actually shop and negotiate.
Can a processor waive interchange fees?
No legitimate processor can waive interchange - it's a wholesale cost paid to the issuing bank. If a provider claims "zero fees," they're almost always using surcharging or a cash-discount program to pass the cost to your customer, not eliminating it.
Why do rewards and business cards cost more to accept?
Premium rewards and corporate cards carry higher interchange because a portion of that fee funds the cardholder's points, cash back, and perks. When a customer pays with a high-tier travel card, you're partly subsidizing their rewards.
How often do interchange rates change?
The networks update interchange schedules about twice a year, usually in April and October. Regulatory action and legal settlements can shift them at other times, so it's worth reviewing your effective rate annually.
Apex Pay builds transparent, interchange-plus payment setups for the small and mid-sized businesses the big processors overlook. If you can't find interchange, assessments, and markup as three separate lines on your statement, you're probably overpaying - and we can show you where.
