Quick Answer

Your merchant statement shows every charge associated with card processing for the month. To audit your costs: (1) find your total fees and total volume, (2) divide fees by volume to get your effective rate, (3) compare the effective rate to what you were quoted, and (4) review fixed monthly fees for any charges you didn't expect.

What Is a Merchant Statement?

A merchant statement is the monthly document your payment processor sends (or makes available online) summarizing your transaction activity, fees, and net deposit for that month. It serves as both an invoice and a record of your processing history.

Statements vary significantly in format across processors — there is no standard layout. Some processors produce detailed statements with interchange-level breakdowns; others provide a simple summary with bundled fees. Knowing what sections to look for is more useful than expecting a specific layout.

Key Sections of a Merchant Statement

1

Account Summary

What it shows: Overview of total transactions, total volume processed, and total amount deposited.
Where to find it: Usually the first page or top section of the statement.
What to look for: Total volume (gross sales) and total fees — these two numbers are what you need to calculate your effective rate.
2

Transaction Activity

What it shows: A breakdown of each batch or daily settlement, showing transaction count, gross volume, and fees per batch.
Where to find it: Middle section, often organized by date.
What to look for: Consistent batch volumes and any unusually high fee days.
3

Interchange Detail

What it shows: On interchange-plus statements, a line-by-line breakdown of every interchange category your transactions were processed at, with the specific rate and fee for each.
Where to find it: Often labeled 'Interchange Detail,' 'Interchange Summary,' or 'Network Fees.'
What to look for: The distribution of your card mix across interchange categories — this is where you can see what card types your customers use.
4

Processor Fees

What it shows: The fees charged by your processor on top of interchange: markup percentage, per-transaction fees, monthly fees, and any other charges.
Where to find it: Varies by processor — may appear as a separate section or integrated with transaction detail.
What to look for: The markup rate and per-transaction fee. Compare these to what you were quoted.
5

Monthly Fixed Fees

What it shows: Recurring fees charged regardless of transaction volume: monthly service fee, statement fee, PCI compliance fee, gateway fee, and similar charges.
Where to find it: Often at the bottom of the statement in a 'Fees' or 'Monthly Charges' section.
What to look for: Any fees you weren't aware of when you signed up. Fixed fees can be significant for low-volume merchants.
6

Adjustments and Chargebacks

What it shows: Refunds, chargebacks, dispute fees, and other adjustments to your settled funds.
Where to find it: May appear as a separate section or within transaction activity.
What to look for: Chargeback fees and their frequency. Elevated chargeback activity can affect your processing relationship.
7

Funding Summary

What it shows: The total amount deposited into your bank account after all fees were deducted.
Where to find it: Often on the final page or in the account summary.
What to look for: Whether this matches your expected deposit based on your volume and fee structure.

Questions to Ask After Reviewing Your Statement
