How to Read a Merchant Processing Statement

By the TouchSuite payments team · Updated 2026-11-02

To read a merchant processing statement, split every charge into three buckets: interchange (paid to the card-issuing bank), assessments (paid to the card brand), and everything else (your processor's markup and fees). Then compare your gross card sales to what was actually deposited in your bank account, because that gap is your true monthly cost.

The four parts of every merchant statement

Layouts vary by processor, but nearly every statement contains the same four blocks. The summary shows total sales volume, refunds, chargebacks, fees, and the net amount paid to you. The deposit log lists each batch you settled and the amount that hit your bank account. The card-type section breaks volume down by Visa, Mastercard, Discover, and American Express, and often by debit versus credit. The fee section itemizes every charge.

Read them in that order. The summary tells you the month's scale, the deposit log tells you what you actually received, the card-type section tells you why your costs look the way they do (rewards credit cards and card-not-present transactions cost more than in-person debit), and the fee section tells you who is charging what. Skipping straight to the fee section is how most owners get lost in hundreds of lines of codes.

What each type of charge actually is

Interchange is the largest cost on most statements. It is paid to the bank that issued your customer's card and is set by the card brands' published tables, varying by card type, how the card was accepted (tapped, keyed, online), and your industry. On an interchange-plus statement you will see lines like 'Visa CPS Retail Debit' or 'MC World Elite Card Present,' each with a percentage and often a small per-item amount.

Assessments, sometimes labeled card brand fees or network fees, go to Visa, Mastercard, Discover, and Amex. They are typically a small fraction of a percent of volume plus small per-transaction network fees with names like acquirer processing fee or network access fee. Like interchange, these are not set by your processor, though processors decide whether to pass them through at cost.

Everything else belongs to your processor or its partners. That includes the markup (a percentage on top of interchange, such as 0.25%), a per-item or authorization fee (such as $0.10 per transaction), batch fees, gateway fees, monthly statement or account fees, PCI compliance or non-compliance fees, and annual fees. This bucket is where two processors handling identical transactions can charge very different amounts.

Worked example: reading a sample statement

Here is a made-up but realistic example for a small apparel boutique on interchange-plus pricing. Sales volume: $42,000 across 610 transactions, settled in 30 daily batches. Interchange: $693.00. Card brand assessments and network fees: $59.00. Processor markup at 0.25%: $105.00. Per-item fee at $0.10 x 610: $61.00. Batch fee at $0.25 x 30: $7.50. Gateway fee: $15.00. Monthly statement fee: $9.95. PCI non-compliance fee: $29.95. Total: $980.40.

Divide total fees by volume and the effective rate is about 2.33% ($980.40 / $42,000). Now sort it into buckets: $752 (interchange plus assessments) is pass-through cost, and $228.40 is processor revenue. Of that, $29.95 is a PCI non-compliance fee that may disappear simply by completing the annual self-assessment questionnaire. That single line is worth a phone call. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

Doing this sorting by hand on a real statement takes time, especially when line items use cryptic abbreviations. Our free [Hidden Fee Finder: Merchant Statement Checker](https://touchsuite.com/tools/hidden-fee-finder) lets you tick the fees that appear on your statement, enter your volume, and see your real effective rate along with which charges deserve a question. (If you want the math behind the effective rate itself, see our guide How to Calculate Your Effective Rate.)

What most guides get wrong: trusting the 'total fees' line

Most articles tell you to find the total fees figure in the summary and divide it by volume. That works only if all fees are billed in one place. Many processors use daily discount: some or all of the percentage fees are subtracted from each day's deposit before the money reaches you. Depending on the statement format, those daily deductions may appear in the deposit log rather than the fee summary, so the 'total fees' box shows only the month-end charges and your effective rate looks lower than it really is.

The reliable check is to work from cash. Take gross card sales, subtract refunds and chargebacks, and compare the result to the sum of every deposit for the month (plus any reserve withheld). In the boutique example, if gross sales were $42,000 with no refunds and deposits totaled $41,019.60, the gap is $980.40, which matches. If the summary had shown only $320 in fees but the deposit gap was still $980, the remaining $660 was taken daily and is just as real.

Watch the timing too. Monthly-discount statements often bill fees early in the following month, so a single statement may reflect last month's activity. Compare two or three consecutive months before drawing conclusions.

Deposits, holds, and reserves

The deposit log should show one line per batch with the gross amount, any deductions, and the net deposit. If a batch is missing or delayed, that is usually a hold: the processor paused funding, often because of an unusually large ticket, a spike in volume, or a risk review. Holds are temporary, but you should be told why and when funds will release.

A reserve is different. It is a portion of your deposits set aside as protection against future chargebacks and refunds, common in higher-risk industries, subscriptions, and businesses that take payment long before delivery. A rolling reserve might withhold, for example, 5% of each day's deposits and release each amount after a set period such as 90 or 180 days. On a $42,000 month, a hypothetical 5% rolling reserve would hold back $2,100. That is not a fee, but it is cash you cannot use, and your statement should show the reserve balance and release dates. If it does not, ask for a reserve report.

Tiered statements and charges worth questioning

If your statement shows only a few rates labeled qualified, mid-qualified, and non-qualified, you are on tiered pricing. Interchange and markup are blended together, so you cannot see what the processor keeps. The key line to watch is the non-qualified volume: in a made-up example, if 30% of your volume is billed at a non-qualified rate of 3.49% instead of a qualified 1.69%, those 'downgrades' can dominate your cost. Ask what rule moves a transaction from one tier to another.

On any pricing model, these line items deserve a direct question: a PCI non-compliance fee that recurs every month; vague names like regulatory fee, service fee, or account maintenance that do not map to a card brand charge; per-item fees charged twice (once as authorization, once as transaction); a markup that has crept up since your last statement; and annual or 'membership' fees you did not agree to. Also check the fine print near the top or bottom of the statement, where pricing change notices are often printed.

What to do with what you find

Pull your last three statements, separate pass-through costs from processor charges, and reconcile gross sales against deposits for each month. List every line you cannot explain and ask your processor to define it in writing, including whether it is a card brand fee or the processor's own fee.

If you would rather have someone walk through it with you, a TouchSuite payments specialist can review your statement line by line and explain what each charge is. [Talk to a payments specialist](https://touchsuite.com/contact).

Frequently asked questions

How we put this together

The structure and terminology in this guide reflect how interchange and card brand fees are published by Visa, Mastercard, Discover, and American Express in their interchange and fee schedules, and how processors commonly present them on statements. All dollar figures, rates, transaction counts, and reserve percentages in the examples are illustrative assumptions chosen to be realistic for a small retail business; they are not TouchSuite pricing or industry statistics. The Hidden Fee Finder uses estimated industry effective rates and interchange averages by segment, which are labeled as estimates in the tool. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting. Card brand fees change periodically (often in April and October), so verify current interchange and assessment amounts against your own statement and your processor's disclosures, and confirm your contract terms before acting on any comparison.
