Why Are Credit Card Fees So High?
Short answer: you're paying multiple parties at once — and most of it is invisible by design. Here's where your money actually goes.
The Three-Layer Fee Structure
Every credit card transaction passes through three separate entities, each taking a cut. The total you see on your statement is the sum of all three.
1. Interchange — The Biggest Piece
This is the fee paid to the bank that issued the customer's card (Visa, Mastercard, American Express set the rules; banks collect the money). Interchange rates are not negotiable — they're set by the card networks and vary by card type. A basic debit card might be 0.05% + $0.21. A premium rewards card can run 2.3% + $0.10. Your processor passes this through to you whether they tell you or not.
2. Assessment Fees — Small but Fixed
Visa, Mastercard, and Amex each charge a small fee for using their network — typically 0.13%–0.15% of transaction volume. This is non-negotiable. Everyone pays it.
3. Processor Markup — The Only Negotiable Part
Your payment processor (Stripe, Square, your bank's merchant services, etc.) adds their own margin on top of interchange + assessment. This is where the variance lives. Flat-rate processors like Stripe bundle everything into one number (2.9% + $0.30) and profit on the spread. Interchange-plus processors show you the actual cost and charge a transparent markup above it.
What You're Actually Paying
| Fee Layer | Who Gets It | Typical Range | Negotiable? |
|---|---|---|---|
| Interchange | Card-issuing bank | 0.05% – 2.40% | No |
| Assessment | Visa / Mastercard / Amex | 0.13% – 0.15% | No |
| Processor markup | Your processor | 0.20% – 1.50%+ | Yes |
| Monthly / gateway fees | Your processor | $0 – $50/mo | Sometimes |
Why the Number on Your Statement Looks Higher Than Expected
Flat-rate processors (Stripe, Square, PayPal) average across all card types. When a customer pays with a heavy rewards card, those fees are above average — and you absorb it. At high volume, this averaging becomes expensive.
Monthly fees amortized across transactions add to your effective rate. A $25/month gateway fee on $10,000 in volume is an extra 0.25%. Most business owners don't account for this.
Card-not-present transactions (online, phone orders) always cost more than in-person. The network considers them higher risk.
The honest benchmark: Most card-present retail businesses should pay an effective rate (total fees ÷ total volume) of 1.7–2.3%. If you're above 2.9% on in-person volume, you're likely paying too much. Text PJ your last statement — we'll calculate your effective rate for free.
What You Can and Can't Change
You can't change interchange or network fees. You can negotiate your processor's markup, choose a pricing model (flat-rate vs. interchange-plus), eliminate unnecessary monthly fees, and switch processors if you're being overcharged.
The most impactful thing most operators can do: switch from flat-rate to interchange-plus pricing. For any business doing over $10k/month in card volume, the math almost always works in your favor.
