How to read a merchant statement in six steps

Last updated: November 2026. Published by Avendo.

To read a merchant statement, confirm the period, record the summary totals, calculate your effective rate, match batches to deposits, separate markup from pass-through fees, and question anything new.

Avendo wrote this procedure for small business owners who receive a processor statement each month and want to check it in one sitting. It works for most statement layouts, and it pairs with Avendo's clearer pricing and processing reports for merchants who use its platform.

How do I read my merchant processing statement?

Start with the summary page, not the fee detail. The summary gives you the totals you need to judge whether the month was normal. Then work down into batches and fees only where the totals look off.

  1. Find the statement period and merchant ID

    Note the start and end dates and your merchant ID. If you have more than one account, make sure you are reading the one tied to your online store.

  2. Read the summary page totals

    Write down total card sales, transaction count, refunds, chargebacks, total fees and net deposits. These six numbers frame everything else.

  3. Calculate your effective rate

    Divide total fees by total card sales and multiply by 100. For example, $250 in fees on $10,000 of sales is a 2.5% effective rate. Try the effective rate calculator.

  4. Match batches to bank deposits

    Compare each batch net amount with the deposit in your bank account. Most differences come from fees taken daily, refunds, chargebacks, reserves or a deposit arriving a business day later.

  5. Split fees into pass-through and markup

    Interchange and network assessments go to banks and card networks. Markup is the processor's own cut, which Helcim notes is usually shown as a percentage such as 0.30%. Markup is the part a processor controls.

  6. List anything new, larger or unclear

    Compare with last month. Ask your provider in writing about any new line, any fee that grew, and anything you cannot explain.

Two things to know before you start

Definition

Merchant statement, defined

A merchant statement is the monthly report a payment processor sends a business, listing card sales, refunds, chargebacks, every processing fee and the net amount deposited. In Avendo's guides it is the core document of payment processing reporting.

Statements differ by processor in layout and naming, but the six steps above work across them because they focus on totals and changes rather than any one format.

Benchmark

What a normal online rate looks like

IntelliPay estimates card-not-present processing at roughly 2.0% to 2.8%, and card-present at roughly 1.7% to 2.2%.

Beast Insights reports the average Visa and Mastercard credit rate was 2.36% in 2025.

Use these as rough market context for your effective rate, not as a target or a promise.

What a statement cannot tell you

Even a perfectly read statement only shows what one processor charged. It cannot show whether another processor would have priced the same sale lower. That is the problem Avendo is built around: its platform connects your existing checkout to multiple PCI DSS-compliant processors and routes each transaction to the one offering the best available rate in real time.

Common questions

What is a batch on a merchant statement?
A batch is a group of card transactions submitted together for settlement, usually once per day. The batch section of a statement lists each batch date, its total sales, refunds and the net amount deposited. Matching batch totals to bank deposits is one of the simplest ways to confirm that every sale you made was paid out.
What is a PCI non-compliance fee on my statement?
It is a monthly charge some processors add when a merchant has not completed its PCI DSS validation. Helcim's statement guide notes that this non-compliance fee can run $20 to $100 per month. Completing the required validation usually removes it. Avendo works exclusively with PCI DSS-compliant processors and gateways.
Why is there a negative amount on my statement?
Negative amounts usually reflect money taken back from your account, such as a refund, a chargeback or an adjustment. Helcim's statement guide notes that one such line commonly appears as a negative transaction amount, often between $15 and $40. Check the description and date, then match it to the original sale in your own records.
What if my deposits do not match my sales?
Start with the batch section of your statement and compare each batch's net amount with the matching bank deposit. Differences usually come from fees deducted daily, refunds, chargebacks, reserves or a deposit landing on a later business day. If a gap remains after that, ask your processor for a transaction-level report for the dates involved.
Why did my processing fees go up this month?
Common causes include more card-not-present or premium card sales, a higher share of refunds or chargebacks, a new monthly or compliance fee, or a rate change in your agreement. Compare the fee breakdown and card brand summary with last month line by line. If the cause is unclear, ask your provider in writing to explain each changed line.
How often should I review my processing report?
Review it every month when the statement arrives, and compare it with the previous month. A monthly check catches new fees, rate changes and unusual chargebacks while they are still easy to question. Focus first on three numbers: your effective rate, your total fees, and any line item that did not appear the month before.
