Make sense of your processing statement.

Last updated September 17, 2026.

Your monthly processing statement is the only place you can see what accepting cards really costs your business, yet many owners never get past the total at the bottom. The good news: every statement, no matter how cluttered, answers the same three questions. How much did you process, how much did you pay, and who got that money? This guide shows you where to look.

Key takeaways

• Start with your effective rate: total fees divided by total card sales. It's the single number that lets you compare months and providers.
• Every card fee has three parts: interchange (to the card-issuing bank), network fees (to Visa, Mastercard, and others), and your provider's markup [1].
• Flat-rate statements bundle everything into one rate; interchange-plus statements itemize it; tiered statements sort transactions into buckets the provider defines.
• Watch the non-transaction fees too: monthly, PCI, statement, chargeback, and early termination fees. The FTC has sued a processor over surprise exit fees [2].

Step 1: Find the three numbers that matter

Before decoding any line items, locate these on the summary page:

1. Total card volume (sometimes "gross sales" or "amount submitted"): the dollar value of card sales processed.
2. Number of transactions: helps you see how much per-transaction fees (the "cents" part of "2.9% + 30¢") add up.
3. Total fees: sometimes shown as "fees charged," "discount," or a single deduction from deposits.

Then calculate:

Effective rate = total fees ÷ total card volume × 100

If you processed $20,000 and paid $560 in fees, your effective rate is 2.8%. Track this monthly. A jump without a change in your sales mix is a signal to read the detail pages closely.

Check how fees are collected

Some providers deduct fees from each deposit ("daily discount"); others take them in one debit at month-end ("monthly discount"). With monthly billing, your deposits look bigger than your true net, so reconcile against the statement, not just your bank account.

Step 2: Identify your pricing model

Your statement's layout usually tells you which model you're on.

Stripe, which offers both models, describes flat-rate pricing as "a single, all-inclusive rate no matter what kind of card your customer uses," and notes that with it "you might overpay on lower-cost transactions because the rate will be set high enough to cover the expensive ones" [1]. It also says interchange-plus "comes with unpredictability and complexity" because network costs change [3].

Step 3: Read the interchange section (IC+ and some tiered statements)

On an interchange-plus statement, you'll see many rows with names like "MC World Elite Supermarket" or "Visa CPS Retail Debit." Each row typically lists:

• Category name: the card network's rate category
• Count and volume: how many transactions and dollars fell in that category
• Rate: a percentage plus a per-item amount
• Total: interchange for that row

Categories come from the networks' published schedules. For example, Mastercard's U.S. schedule effective April 17, 2026, lists 1.45% + $0.10 for a Core consumer credit card in its Supermarket Base category and 2.10% + $0.10 for a World Elite card in the same category [4]. So a spike in rewards-card use can raise your bill even if your provider changed nothing.

Spot downgrades

A downgrade happens when a transaction doesn't meet the requirements for its best category (for example, it settled late or was missing data) and falls into a more expensive one. Look for category names containing words like "Standard," "Data Rate I," or "Key Entered" on sales you expected to be card-present. Stripe says that for online sales, passing the customer's ZIP code can reduce network costs by up to 1.45% of the transaction amount, depending on card type [3].

Recognize debit categories

Debit cards from banks with $10 billion or more in assets are capped by the Federal Reserve's Regulation II at $0.21 plus 0.05% (plus up to 1 cent for fraud prevention) [5]. On Mastercard's schedule this appears as "Regulated POS Debit" [4]. Debit cards from smaller banks and credit unions are exempt and cost more: in 2024, exempt debit transactions averaged $0.51 versus $0.23 for covered ones [5]. The cap itself is the subject of an ongoing appeal. Related field note

Step 4: Read the network (card brand) fees

Network fees, also called assessments, scheme fees, or card brand fees, go to the card networks. They usually show up as a separate section with small percentages and fractions of a cent. Common names include:

On a true interchange-plus plan, these should be passed through at cost. If a network fee line shows a rate that seems higher than the network's, ask your provider whether it is marked up.

Step 5: Find your provider's markup

This is the only part of the bill your provider fully controls. On IC+ statements it's usually labeled "discount rate," "processing markup," "authorization fee," or "transaction fee," and looks like "0.40% + $0.08." On flat-rate statements, the markup is hidden inside the single rate. On tiered statements, the markup is the gap between your tier rates and actual interchange, which you generally can't see.

Step 6: Scan the account-level fees

These don't depend on individual sales but can quietly add up:

• Monthly or account fees, statement fees, and "minimum processing" fees charged if you process too little
• PCI compliance or non-compliance fees, related to the Payment Card Industry security standards your provider requires you to validate annually
• Chargeback fees per dispute, plus any retrieval request fees. Published amounts vary by provider (for example, $15 at Stripe for a dispute received; Square says it doesn't charge for chargebacks) [7][8]
• Payout or instant transfer fees for faster access to funds
• Equipment leases, which can outlast the equipment's value
• Early termination fees in multi-year contracts

The FTC's 2022 case against First American Payment Systems alleged that sales reps promised businesses they could cancel without a fee, while standard contracts carried three-year terms and $495 cancellation fees; the company and related parties agreed to pay $4.9 million [2]. That case is a reminder to compare the statement against the contract, not the sales pitch.

A worked example (hypothetical)

A café processes $20,000 in card sales across 400 transactions in a month (average $50). All numbers below are illustrative, not quotes from any provider.

The comparison flips easily. If more customers used premium rewards cards or paid online, interchange would climb and the IC+ total could exceed the flat rate. If most used regulated debit, IC+ could fall well below it. That's why two businesses can reach opposite conclusions about the same two plans.

Step 7: Questions to ask your provider

• Which pricing model am I on, and where is it stated in my contract?
• Are network fees passed through at cost?
• What changed since last month if my effective rate rose?
• Which transactions downgraded, and why?
• What account fees, minimums, and termination fees apply?

Also watch for industry changes. A revised Visa/Mastercard merchant settlement received preliminary court approval on June 9, 2026; if finalized, it could affect interchange rates and surcharging options, but it is not in effect yet [9].

FAQ

What is a good effective rate? There's no single benchmark. It depends on your card mix, average ticket, industry, and whether sales are in person or online. Use your own history and competing quotes built on your actual statement.

Why did my fees go up when my sales didn't change? Common causes include more premium or online card use, downgrades, network fee changes, or a provider price change. Compare line items month over month.

Is interchange-plus always cheaper than flat-rate? No. It passes through actual costs, which can be lower or higher than a flat rate depending on your transactions [1][3].

What does "non-qualified" mean on my statement? It's a tier your provider uses for transactions it prices higher, often rewards cards, keyed-in sales, or transactions missing data. The provider's contract defines the rules.

Can I negotiate processing fees? Providers may adjust markups and account fees, especially for higher volume. Interchange and network fees are set by the networks, not your provider.
