How to Read a Merchant Processing Statement
Merchant statements vary by processor, but most follow a similar structure. Once you know what each section is for, you can find the two or three numbers you need for an effective rate calculation in minutes.
Protect sensitive information
Do not photograph, upload, or share complete statements containing full card numbers, bank account numbers, Social Security numbers, or routing numbers. You only need summary totals to use the calculator.
Typical statement sections
1. Account summary
Usually on the first page. Shows your business name, merchant ID, and the statement period. Confirms you have the right statement and the right time window.
2. Sales summary
Lists total card sales, total transactions, refunds, and net deposits for the period. The total card sales figure here is what you enter as "Monthly card sales" in the calculator. Use the gross settled card sales amount, not the net deposit after fees.
3. Fee summary
The most important section for the calculator. Look for a subtotal or total that combines all processing charges. On interchange-plus statements this section may be split into interchange, assessments, and processor markup. On flat-rate or tiered statements it may be a single blended charge. Add all processing-related fees together to get your total processing fees figure.
4. Interchange detail (interchange-plus statements)
Shows how much was paid at each interchange category. Card networks set these rates; your processor passes them through. This section can be several pages long. You do not need to add each line — look for the interchange subtotal.
5. Monthly and fixed fees
Recurring charges such as a monthly statement fee, account maintenance fee, or minimum processing fee. These may appear at the bottom of the fee summary or in a separate section. Include them in your total processing fees if they are already combined in a "total fees" line. Add them in the additional fees field only if they are listed separately and not in the total.
6. Other charges
May include PCI non-compliance fees, chargeback fees, retrieval fees, or batch fees. Review this section carefully — unexpected charges often appear here.
The two numbers you always need
| What you need | Where to find it |
|---|---|
| Total card sales | "Total sales," "gross card sales," or "total volume" in the sales summary |
| Total processing fees | "Total fees," "total charges," or sum of all fee sections |
| Transaction count (for average fee per transaction) | "Total transactions" in the sales summary |
Common statement formats by pricing model
Flat-rate statements (e.g., Square, Stripe) show a single percentage charged on gross volume. Fees are simple to find — usually one line or a fee summary.
Interchange-plus statements show interchange broken out by card type, assessments from the networks, and a separate processor markup. You must add all three categories to get total fees.
Tiered statements group transactions into "qualified," "mid-qualified," and "non-qualified" tiers with different rates. Look for a total charges or total fees line that sums all tiers.
Warning signs to look for
- Fees with no label or unclear descriptions
- Non-compliance fees (PCI) when you have completed compliance validation
- A "minimum monthly fee" charged even in a high-volume month
- Chargeback fees without a corresponding dispute you recognize
- Equipment or lease fees far above the terminal's purchase price over time
- Fees that increased from the prior month without a notice
