Every month, money leaves your business for card processing, and a statement arrives to explain it. For most owners that statement is the hardest document they receive. It runs several pages, uses its own vocabulary, and seems designed so that the total is the only number that's easy to find.
You don't need to become a payments expert to read it. You need to know where four things are: what you sold, what you paid, which pricing model you're on, and which charges are set by the card networks versus your processor. This guide walks through each one in the order you'll meet them on the page.
Key takeaways
- Your effective rate is total fees divided by total card sales. It's the fastest health check, but it can't tell you whether your price is fair.
- Every statement mixes three layers of cost: interchange (set and published by Visa and Mastercard), card network fees, and your processor's own markup. Only the markup is negotiable.
- Your pricing model (flat rate, tiered, interchange-plus or subscription) decides how much of the statement you can actually check.
- Read the message box. Price changes are usually announced there, and staying put often counts as accepting them.
- Some costs, like equipment leases, may not be on the processing statement at all. Check your bank statement too.
Step 1: Find the summary, which is what you sold and what you paid
Most statements open with a summary page. Look for three numbers:
- Total sales (or gross volume): the card sales processed during the period, usually broken out by card brand.
- Total fees (or total charges, discount due, fees charged): everything you paid to accept cards that month.
- Net deposits: the money that actually reached your bank account.
Write down the first two. Everything else on the statement explains how one became the other.
One caution: some processors take fees out of each day's deposit ("daily discount"), while others take them in one debit at the start of the next month ("monthly discount"). If your deposits always look smaller than your sales, you're probably on daily discount. That doesn't change what you pay, only when you pay it.
Step 2: Calculate your effective rate
Your effective rate is the single most useful number you can compute in thirty seconds:
Effective rate = total fees ÷ total card sales
For example, if you processed $20,000 in card sales and paid $620 in total fees, your effective rate is 3.10%.
Industry surveys put typical all-in processing costs at roughly 1.5% to 3.5% of sales, depending on the business (NerdWallet, 2026). The Nilson Report put the weighted average Visa and Mastercard fee at 2.35% in 2024 (Payments Dive).
Treat those as context, not as a target. Your effective rate depends heavily on things a benchmark can't see:
- Card mix. Premium rewards and business cards cost more to accept than basic debit cards.
- How cards are taken. Online and keyed-in transactions cost more than chip or tap.
- Ticket size. Per-transaction fees weigh more heavily on small sales.
- Your business type. Some industries get lower published rates.
Two businesses with identical pricing can have very different effective rates. That's why the effective rate tells you whether to look closer, not whether you're overpaying. To answer that, you have to separate what you pay into its layers.
Step 3: Identify your pricing model
Before you go line by line, work out which pricing model you're on. It determines what the rest of the statement can tell you.
| Pricing model | What it looks like on the statement | What you can check |
|---|---|---|
| Flat rate | One rate for most transactions (for example, a single percentage plus a per-transaction fee), few separate fee lines | Very little. The processor's cost is hidden inside the one rate. |
| Tiered | Lines labeled qualified, mid-qualified and non-qualified (sometimes non-qual or surcharge), each with its own rate | Limited. The processor decides which tier each transaction lands in. |
| Interchange-plus (also called cost-plus or pass-through) | Many lines naming card programs (such as CPS/Retail or Merit III), plus a separate markup percentage or per-item fee | Where the program, transaction details, period and applicable schedule are supported. Ambiguous or unmatched lines remain questions. |
| Subscription or membership | Interchange at cost plus a fixed monthly fee and a small per-transaction fee | Most of it, as with interchange-plus. |
If your statement has dozens of program names and a separate line for the processor's markup, you're on interchange-plus or subscription pricing. If it has three rate tiers, you're on tiered pricing. If it has one rate, you're on flat rate.
Step 4: Separate the three layers of cost
Whatever the pricing model, the money you pay is split three ways. Your statement may not separate them for you, but they're always there.
Layer 1: Interchange, set by the card networks
Interchange is the largest part of most processing bills. It goes to the bank that issued your customer's card. Visa and Mastercard set the rates and publish them:
- Visa U.S.A. Interchange Reimbursement Fees (April 2026 schedule);
- Mastercard U.S. interchange rates (April 2026 schedule).
April and October are the two windows when the networks can change U.S. rates, but they don't use every window. In October 2026, neither Visa nor Mastercard changed its U.S. interchange rates, so the April 2026 schedules are still the ones in force.
Interchange is the same for every business that qualifies for the same program. You don't negotiate it, and neither does your processor. What varies is which program each transaction qualifies for. That depends on:
- the card type (debit, rewards, business);
- how it was accepted (chip, tap, online, keyed);
- your industry;
- sometimes the ticket size.
Layer 2: Card network fees
Visa and Mastercard also charge their own fees on every transaction, often labeled assessments, brand fees, network fees, or by names like APF (Visa) and NABU (Mastercard). They're small compared with interchange, but they appear on almost every statement as their own lines.
Layer 3: Your processor's markup
Everything above interchange and network fees is your processor's own price. It might be a percentage, a per-transaction fee, monthly fees, or the difference between a tiered rate and the true cost underneath it. This is the only layer that's set by your agreement, and the only layer that's negotiable.
Why this matters: "Can you lower my rate?" is a much stronger question when you know which dollars are the network's and which are your processor's. Without that split, a new quote is a number you have no way to check.
Step 5: Read the interchange section (interchange-plus statements)
On an interchange-plus statement, the interchange section is usually the longest part. Each line typically shows:
- The program name, such as Visa CPS/Retail Credit or MC Merit III Debit;
- The number of transactions and sales volume for that program;
- The rate, usually a percentage plus a per-transaction amount;
- The fee charged for that line.
Where the program, card and transaction details, statement period, and applicable schedule are supported, compare the billed percentage and per-item amount with the published schedule. If a supported billed rate is higher, ask whether the difference is processor markup included in a line labeled as pass-through cost. Ambiguous or unmatched lines should remain unresolved rather than being assigned a rate.
Also look for downgrades: transactions that landed in a more expensive program than they could have qualified for. They usually come from setup problems rather than pricing decisions:
- a terminal not sending the right data;
- a batch closed late;
- a missing address on keyed transactions.
A downgrade fixed at the terminal often stops on the next statement.
Step 6: On a tiered statement, look at the non-qualified tier
On tiered pricing, your processor sorts transactions into qualified, mid-qualified and non-qualified buckets, each priced higher than the last. The card networks don't define those buckets; your processor does.
Things to check:
- What share of your volume is non-qualified? If it's a large part of your sales, ask why. Rewards cards, business cards and keyed transactions are common reasons.
- Is there a "non-qualified surcharge" on top of the tier rate? Some statements add one.
- Does the qualified rate apply to many of your transactions at all? A low headline qualified rate means little if most volume lands elsewhere.
Tiered pricing isn't wrong, but it's the hardest model to verify, because the processor's true cost isn't on the page.
Step 7: Find the other fees
After the transaction fees, most statements list account-level charges. Common ones include:
- Monthly, statement or account fee: a fixed charge every month.
- PCI compliance fee: an annual or monthly charge for the processor's data-security program.
- PCI non-compliance fee: a monthly penalty that usually applies until you complete an annual security questionnaire (the SAQ). It often ends once the form is filed. It's one of the most common avoidable charges.
- Batch or settlement fees: a charge each time you close out your terminal.
- Authorization fees: a per-attempt charge, including declined transactions.
- Gateway fees: for online or virtual-terminal processing.
- Chargeback and retrieval fees: charged when a customer disputes a transaction.
- Annual or "service and maintenance" fees: sometimes billed once a year, which makes them easy to miss.
- Minimum monthly fees: a top-up charge if your processing fees fall below a set amount.
None of these is wrong in itself. The question for each is whether it's in your agreement, whether it's still needed, and whether it can be removed.
One cost you won't find here: equipment leases are often with a different company than your processor and are debited straight from your bank account, so they usually don't appear on the processing statement at all. Check your bank statement for a regular debit from a leasing company.
Step 8: Read the message box
Near the top or the end of most statements is a short block of text that looks like legal filler. It's where processors announce price changes, new fees and changes to your terms, often weeks before they take effect. In many agreements, if you don't object in time, continuing to process counts as accepting the change.
Notices are sometimes vague. A line like "rates will increase by 0.25%" could mean a quarter of a percentage point, or a quarter of a percent of your current rate, and those are very different amounts. If a notice doesn't say which, ask in writing.
A 10-point checklist for your next statement
- Write down total sales and total fees, and calculate your effective rate.
- Compare it with the last few months. A jump with no change in your business is a question.
- Identify your pricing model.
- On interchange-plus, spot-check a few interchange lines against the published schedules.
- On tiered, find the share of volume in the non-qualified tier.
- Find your processor's markup, and confirm it matches your agreement.
- Look for a PCI non-compliance fee, and file the questionnaire if it's there.
- List every monthly and annual fee, and ask about any you don't recognize.
- Read the message box for notices of changes.
- Check your bank statement for lease payments or other debits from your processor.
When the statement doesn't add up
Some statements can't be fully checked from the page. The summary doesn't reconcile to the detail, the interchange lines don't match any published program, or the pricing model hides the processor's cost.
That's what Statement Forensics does. You send one to three statements and get back an independent audit:
- statement totals reconciled where the printed detail supports the comparison, with unresolved differences identified;
- supported Visa and Mastercard lines compared with the dated schedules available for the statement period;
- your processor's markup separated from the wholesale cost.
Where a statement can't answer a question, the report says so and gives you the question to ask instead.
We don't sell processing. We have no processor or ISO affiliation, and we take no residuals or referral fees, so there's nothing to switch you to. Statements sent for an audit are used to produce the reports and deleted when they're delivered. US statements only.

Frequently asked questions
What is a good effective rate for credit card processing?
There isn't a single good number. Typical all-in costs run about 1.5% to 3.5% of sales, but your rate depends on your card mix, how you take cards, your average ticket and your industry. Compare your rate with your own history, then check the layers underneath it. A low rate can still include avoidable fees, and a higher rate can be fair for a business that takes mostly rewards cards online.
What does "non-qualified" mean on a merchant statement?
On tiered pricing, non-qualified is the most expensive bucket a transaction can land in. Your processor decides which transactions go there. Common reasons are rewards or business cards, keyed-in transactions, and transactions missing data the networks require. If a large share of your volume is non-qualified, ask your processor why.
Can I negotiate interchange fees?
No. Interchange is set and published by Visa and Mastercard, and it's the same for every business that qualifies for the same program. What you can negotiate is your processor's markup and fees. You can also reduce how often your transactions land in more expensive programs, for example by fixing terminal settings that cause downgrades.
What is a PCI non-compliance fee, and how do I stop paying it?
It's a monthly charge many processors add until you complete your annual PCI Self-Assessment Questionnaire (SAQ), and in some cases quarterly security scans. Ask your processor which form applies to your business and how to submit it. Once it's accepted, the fee usually stops.
How often do interchange rates change?
April and October are the two windows when Visa and Mastercard can change U.S. interchange rates, but they don't change rates in every window. There were no U.S. interchange rate changes in October 2026, so the April 2026 schedules still apply. If a notice on your statement blames "card brand" or "interchange" changes for a price increase, ask which published rate changed.
Is my processing statement the same as my bank statement?
No. The processing statement explains the card activity your processor handled and the fees it charged. Your bank statement shows the deposits and debits that actually hit your account, including charges that may not appear on the processing statement, such as equipment leases or annual fees drafted separately.
