Your Statement Shouldn't Need a Decoder Ring
Credit card processing statements are deliberately complex. The more confusing your statement is, the harder it is for you to question the charges — and the easier it is for your processor to pad their margins.
This guide breaks down every common processing fee into three categories:
- Fees you can't avoid (interchange, assessments — paid to card networks and banks)
- Fees you can negotiate (processor markup — paid to your processor)
- Fees you should eliminate (junk fees — pure profit for your processor)
By the end, you'll be able to read your statement like a pro and know exactly where your money goes.
Category 1: Non-Negotiable Fees (Card Network & Bank Fees)
These fees are set by Visa, Mastercard, Discover, and American Express. Every processor pays them. They cannot be reduced or eliminated.
Interchange Fees
What it is: The fee paid to the card-issuing bank (your customer's bank) for every transaction.
How much: 0.05% + $0.21 (regulated debit) to 2.40% + $0.10 (premium rewards credit). The exact rate depends on card type, transaction method, merchant category, and transaction size.
Why it exists: Interchange compensates the issuing bank for the risk of extending credit to the cardholder, fraud protection, and the rewards programs they fund.
What to know: Interchange is published by Visa and Mastercard twice a year (April and October). There are over 300 interchange categories. On interchange-plus pricing, you see the exact interchange cost for each transaction. On tiered pricing, interchange is hidden inside bundled "qualified" rates.
Assessment Fees (Network Fees)
What it is: A fee charged by the card network (Visa, Mastercard, Discover, Amex) for using their network.
How much:
- Visa: 0.14% (credit), 0.13% (debit)
- Mastercard: 0.1375% (both)
- Discover: 0.13%
- Amex: 0.15%
Plus small per-transaction fees (NABU, FANF, etc.) ranging from $0.0155–$0.04 per transaction.
Why it exists: These fees fund the card network's operations — authorization systems, fraud detection, dispute resolution, and marketing.
What to know: Assessment fees are small but they're separate from interchange. On a $100 transaction, assessments add about $0.14–$0.15. They're unavoidable and consistent across all processors.
Dues and Assessments (D&A)
What it is: A catch-all line item that combines network assessment fees, access fees, and various card brand charges.
How much: Typically 0.13%–0.15% of total volume.
Why it exists: This is just the card networks billing for their services.
What to know: If your statement shows "Dues & Assessments" as a single line, it should be roughly 0.13%–0.15% of your total volume. If it's significantly higher, your processor may be padding this category.
Category 2: Negotiable Fees (Processor Markup)
These are the fees your processor charges for their service. They're the only part of your processing cost that you can negotiate.
Processor Markup (Interchange-Plus)
What it is: The percentage + per-transaction fee your processor charges on top of interchange.
How much: Ranges from 0.05% + $0.04 (high-volume merchants) to 0.50% + $0.15 (small merchants). A competitive rate for most small businesses is 0.20%–0.35% + $0.08–$0.12.
Why it exists: This is your processor's revenue — what they earn for providing terminals, support, underwriting, risk management, and settlement services.
What to know: This is where you save money. If your processor won't tell you their markup, you're probably on tiered pricing — and overpaying.
Monthly Account Fee
What it is: A flat monthly fee for maintaining your merchant account.
How much: $0–$25/month (reasonable), $25–$50/month (high).
Why it exists: Covers account maintenance, online reporting portal, and customer support access.
What to know: Many competitive processors charge $0–$10/month. If you're paying $25+, ask for a reduction or find a processor that charges less.
Gateway Fee (Online Transactions)
What it is: A monthly fee for access to a payment gateway (used for e-commerce and online payments).
How much: $10–$25/month, plus $0.05–$0.10 per transaction.
Why it exists: The gateway provides the secure connection between your website and the processor's authorization system.
What to know: If you only process in-person transactions, you don't need a gateway — make sure you're not being charged for one. If you do process online, shop around: some processors include gateway access in their monthly fee.
Chargeback Fee
What it is: A fee charged when a customer disputes a transaction.
How much: $15–$35 per chargeback (reasonable), $35–$100+ (excessive).
Why it exists: Processing a chargeback requires manual review, communication with banks, and administrative work.
What to know: Chargeback fees are standard, but they vary widely. If you're paying $35+ per chargeback, negotiate or switch. And focus on preventing chargebacks to avoid the fee altogether.
Category 3: Junk Fees (Eliminate These)
These fees exist primarily to increase your processor's revenue. Most are unnecessary, outdated, or duplicative.
PCI Non-Compliance Fee
What it is: A monthly penalty for not being PCI-DSS compliant.
How much: $19.95–$99/month.
What to do: Complete your annual PCI Self-Assessment Questionnaire (SAQ). It takes 15 minutes. Once compliant, the fee should disappear. If your processor still charges it, leave.
PCI Compliance Fee
What it is: A monthly or annual fee for "providing" PCI compliance tools.
How much: $4.95–$14.95/month or $99–$199/year.
What to know: Some processors charge this on top of the non-compliance fee. You're literally paying whether you're compliant or not. Many good processors include PCI compliance at no additional cost.
Statement Fee
What it is: A monthly charge for generating your processing statement.
How much: $5–$15/month.
What to do: Switch to electronic statements (free) and ask for the fee to be waived. If they won't waive $10/month, imagine how they handle real issues.
Annual Fee
What it is: A yearly charge billed once per year, often appearing in a single month's statement with no warning.
How much: $49–$199/year.
What to do: Ask for it to be waived. If they won't, factor it into your total cost comparison when shopping processors.
Batch Fee (Settlement Fee)
What it is: A per-batch fee charged every time your terminal settles transactions (usually daily).
How much: $0.10–$0.35 per batch.
What to know: At $0.25/day, this is $91/year. It's small but unnecessary — many processors don't charge it. Negotiate removal.
Regulatory Fee / Compliance Fee
What it is: A vague fee that processors claim covers "regulatory compliance costs."
How much: $4.95–$9.95/month.
What to know: This is almost always pure profit. Regulatory compliance is a cost of doing business for processors — not something they should pass through to merchants.
IRS Reporting Fee / 1099-K Fee
What it is: A fee for generating your 1099-K tax form.
How much: $10–$25/year.
What to know: Processors are legally required to generate 1099-K forms. Charging you for a legal requirement is like a restaurant charging you for them following health codes. Reject this fee.
Minimum Processing Fee
What it is: If your monthly processing fees don't reach a minimum threshold, you're charged the difference.
How much: $25–$35/month minimum.
What to know: If you process consistently, you'll never hit this. But if you have seasonal slowdowns, this fee can add up. Negotiate a lower minimum or find a processor without one.
How to Calculate Your True Processing Cost
Here's the formula for your effective rate — the single number that tells you what you're really paying:
Effective Rate = Total Processing Fees ÷ Total Card Volume × 100
Example:
- Total fees: $847.50
- Total card volume: $32,000
- Effective rate: 2.65%
What's a good effective rate?
- Below 2.0%: Excellent (likely interchange-plus with good markup)
- 2.0%–2.5%: Good (competitive interchange-plus)
- 2.5%–3.0%: Average (room for improvement)
- Above 3.0%: Overpaying (switch processors)
Frequently Asked Questions
Why do my processing fees change every month?
Even on interchange-plus, your fees will fluctuate because interchange varies by card type. Months with more rewards cards or online transactions will have higher interchange costs. Your processor's markup should stay constant — if it doesn't, something is wrong.
What's the difference between a "discount rate" and an "interchange rate"?
On tiered pricing, the "discount rate" is your bundled qualified rate (interchange + markup combined). On interchange-plus, "interchange" is the bank's cost and your markup is shown separately. The discount rate hides the markup; interchange-plus reveals it.
Can I pass processing fees to my customers?
Yes, through a cash discount program or a credit card surcharge program. Cash discount (offering a lower price for cash) is legal in all 50 states. Surcharging (adding a fee for credit cards) is legal in most states but has specific compliance requirements.
How do I know if my processor is overcharging me?
Calculate your effective rate. If it's above 2.5% and you're processing over $10,000/month, you're likely overpaying. Request a free statement analysis to know for sure.
The Bottom Line
Processing fees aren't mysterious — they're just presented that way. Once you understand the three categories (non-negotiable, negotiable, and junk), you can audit your statement in minutes and negotiate from a position of knowledge.
The processors who make their fees clear are the ones worth doing business with. The ones who hide behind complexity are profiting from your confusion.
