Why your statement matters
Your processing statement is the single most important document in your relationship with your payment processor. It tells you exactly what you paid last month, how those charges were calculated, and where your money went. Yet most business owners never read theirs.
That is by design. Many processors use complex formatting, vague line items, and confusing terminology specifically to make it difficult for merchants to identify what they are actually paying. If you cannot read your statement, you cannot question your rates. And if you cannot question your rates, you cannot negotiate better ones.
This guide will change that. By the end, you will be able to pick up any processing statement and understand every line on it.
The anatomy of a processing statement
Every processing statement, regardless of the processor, contains the same core sections. The labels may differ, but the structure is consistent. Here is what to look for and what each section tells you.
Account summary
This section appears at the top of your statement and provides the high-level overview of your month. It typically includes:
- Your merchant ID number (your unique account identifier)
- The statement period (the date range covered)
- Total volume processed (the dollar amount of all transactions)
- Total number of transactions
- Total fees charged for the period
- Net deposit amount (what actually reached your bank account)
| Payzium tip Compare your total volume against your total fees to calculate your effective rate. Divide total fees by total volume and multiply by 100. This single number tells you what percentage of every dollar went to processing. If your effective rate is above 3.5%, you are likely overpaying. |
Transaction detail
This section breaks down your transactions by card type and method. It shows you how many Visa, Mastercard, American Express, and Discover transactions you processed, along with the dollar amounts for each.
Why this matters: different card brands carry different interchange rates. American Express is typically the most expensive, followed by Discover, then Mastercard and Visa. If a large portion of your volume is American Express, your overall effective rate will be higher. This is normal and not something your processor controls.
What to look for:
- Card-present vs. card-not-present: Swiped, dipped, or tapped transactions (card-present) are cheaper than keyed-in or online transactions (card-not-present) because they carry less fraud risk.
- Downgraded transactions: If transactions that should be card-present are showing up as card-not-present, your terminal may not be reading cards correctly. This costs you more on every transaction.
- Batch timing: If you see surcharges for late batches, you may not be settling your terminal daily. Most processors require batches to close within 24 hours.
Interchange fees
Interchange fees are the largest component of your processing costs, typically accounting for 70-80% of your total fees. These are set by the card networks (Visa, Mastercard) and paid to the card-issuing bank. Your processor does not control these rates and cannot negotiate them on your behalf.
Every card transaction falls into an interchange category based on several factors:
- Card type: A basic debit card has a lower interchange rate than a premium rewards credit card. The bank that issued the card determines its category.
- Transaction method: Tap, dip, or swipe (card-present) costs less than manually keyed or online (card-not-present).
- Business type: Your Merchant Category Code (MCC) affects which interchange tier applies. Grocery stores, for example, qualify for lower rates than general retail.
- Transaction size: Some interchange categories have both a percentage and a flat per-transaction fee. Small-ticket transactions feel this more heavily.
Here is a simplified reference table of common interchange categories:
| Card type | Method | Rate | Per txn |
| Visa debit (regulated) | Card-present | 0.05% | $0.21 |
| Visa credit (basic) | Card-present | 1.51% | $0.10 |
| Visa credit (rewards) | Card-present | 1.65% | $0.10 |
| Visa credit (premium) | Card-present | 2.10% | $0.10 |
| MC debit (regulated) | Card-present | 0.05% | $0.21 |
| MC credit (core) | Card-present | 1.55% | $0.10 |
| MC credit (world) | Card-present | 1.73% | $0.10 |
| Amex (standard) | Card-present | 1.60% | $0.10 |
Note: These are approximate rates for illustration. Actual interchange rates are updated by Visa and Mastercard twice per year (April and October) and vary by merchant category. Full interchange schedules are published on the Visa and Mastercard websites.
| Red flag If your statement does not show interchange detail at all, you are probably on a bundled or tiered pricing model. This means your processor is grouping transactions into categories like “qualified,” “mid-qualified,” and “non-qualified” and setting their own rates for each tier. This is the least transparent pricing model and almost always costs more. Ask your processor for interchange-plus pricing, or contact Payzium for a free statement review. |
Processor markup
This is where your processor makes their money. On an interchange-plus statement, the markup is listed separately from the interchange fees. It typically appears as a percentage and a per-transaction fee added on top of interchange.
For example, if your processor charges interchange + 0.25% + $0.10, that means for every transaction you pay the interchange fee (set by the card networks) plus an additional 0.25% of the transaction amount plus $0.10.
Common markup components include:
- Basis point markup: The percentage above interchange (e.g., 0.15%, 0.25%, 0.40%). Lower is better. Competitive rates for most businesses fall between 0.10% and 0.30% above interchange.
- Per-transaction fee: A flat fee on every transaction (e.g., $0.05, $0.10, $0.15). This matters most for businesses with many small transactions.
- Monthly account fee: A fixed monthly charge for maintaining your merchant account. Reasonable range: $5 to $15.
| Payzium tip The processor markup is the only part of your statement you can negotiate. Interchange and assessment fees are non-negotiable. If a processor tells you they can lower your interchange rates, they are either misleading you or they are planning to lower your interchange display while raising your markup to compensate. |
Assessment fees (network fees)
Assessment fees are charged by the card networks (Visa, Mastercard, Discover) for using their payment infrastructure. Like interchange, these are non-negotiable and the same for every processor. They are typically small: around 0.13-0.15% of transaction volume.
Common assessment fees include:
- Network access and brand usage fee (NABU): A per-transaction fee charged by Visa.
- Acquirer program support fee (APF): Charged by Visa on all transactions.
- Mastercard assessment: A percentage-based fee on all Mastercard volume.
- Cross-border fees: Additional charges if the cardholder’s bank is in a different country than your business.
| Red flag Some processors bundle assessment fees into a single line or hide them inside the interchange display. If you cannot see assessment fees as a separate section, your processor may be inflating them as a hidden revenue source. On a properly itemized interchange-plus statement, assessments should always be listed separately. |
Monthly and recurring fees
Beyond per-transaction charges, most processors add fixed monthly fees. Some are legitimate, others are pure profit centers. Here is how to tell the difference:
| Fee name | What it covers | Typical | Verdict |
| Monthly account fee | Maintaining your merchant account | $5-$15 | Normal |
| Statement fee | Generating and delivering your statement | $5-$10 | Normal |
| PCI compliance fee | Maintaining PCI-DSS security standards | $5-$15 | Normal |
| PCI non-compliance fee | Penalty for not completing PCI questionnaire | $25-$100 | Avoidable |
| Gateway fee | Online payment gateway access | $10-$25 | If online |
| Batch fee | Settling daily transactions | $0.10-$0.30 | Normal |
| Annual fee | Yearly account maintenance | $50-$200 | Question it |
| Rate increase notice | Processor raising your rates | Varies | Red flag |
| Regulatory fee | Vague “compliance” surcharge | $5-$50 | Red flag |
| Technology fee | Unspecified “technology” costs | $5-$50 | Red flag |
Chargebacks and adjustments
If a customer disputed a charge during the statement period, the chargeback will appear here along with any chargeback fees. Standard chargeback fees range from $15 to $25 per occurrence. If your processor charges more than $25 per chargeback, that is above average.
This section may also show adjustments, refunds, or credits applied to your account.
The three pricing models (and why it matters)
How your processor structures pricing fundamentally changes what you see on your statement and how much you pay. There are three common models:
Interchange-plus (recommended)
You pay the actual interchange rate for each transaction, plus a fixed markup from your processor. This is the most transparent model because you can see exactly what the card networks charged and exactly what your processor added on top. Payzium uses this model exclusively.
Tiered pricing (common, but less transparent)
Your processor groups transactions into tiers, typically called qualified, mid-qualified, and non-qualified. Each tier has a different rate, and your processor decides which transactions go into which tier. The problem is that you cannot verify whether transactions are being routed to the correct tier, and processors often route transactions to the most expensive tier to increase revenue.
Flat rate (simple, but often expensive)
You pay the same percentage on every transaction regardless of card type or method. This is the model used by services like Square and Stripe. It is simple to understand but typically more expensive than interchange-plus for businesses processing more than $10,000 per month.
| Payzium tip If you are currently on tiered pricing and processing more than $5,000/month, switching to interchange-plus will almost certainly save you money. If you are on flat-rate pricing and processing more than $10,000/month, the same applies. Send us your statement and we will show you the difference. |
The five-minute statement audit
You do not need to understand every line on your statement to identify problems. Here are five checks you can do in under five minutes that will catch the most common issues.
Step 1: Calculate your effective rate
Divide your total fees by your total processing volume. Multiply by 100. If the result is above 3.5%, you are likely overpaying. If it is above 4%, you are almost certainly overpaying.
Step 2: Look for fees you do not recognize
Scan every line item. If you see a fee name you cannot explain, circle it. Common culprits include “regulatory product fee,” “technology access fee,” “enhanced security fee,” and “service program fee.” These are often pure processor profit with no underlying cost.
Step 3: Check for rate increases
Compare this month’s markup rates to last month’s. Some processors raise rates by small increments (0.05% here, $0.02 there) betting that you will not notice. Over a year, these small increases add up to thousands of dollars.
Step 4: Verify your pricing model
If you see the words “qualified,” “mid-qualified,” or “non-qualified” anywhere on your statement, you are on tiered pricing. If you see actual interchange category names (like “VS Credit CPS Retail” or “MC Core”), you are on interchange-plus. You want the latter.
Step 5: Count the monthly fees
Add up every fixed monthly fee on your statement. If the total exceeds $50/month for a standard in-person merchant account, you are paying too much in non-transactional charges. Some processors stack 8 to 10 separate monthly fees that individually look small but collectively are significant.

What to do next
If you have read through this guide and something on your statement does not add up, you have three options.
Option 1: Call your current processor. Ask them to explain every fee on your statement in plain language. If they cannot or will not, that tells you something.
Option 2: Compare quotes. Get pricing from two or three processors and compare their interchange-plus markup rates. Make sure you are comparing the same pricing model.
Option 3: Send us your statement. Payzium offers a free, no-obligation statement review. We will go through your statement line by line and show you exactly what you are paying, what is reasonable, and where you may be overpaying. No sales pitch, no pressure. Just a clear breakdown of the numbers.
