How to Read a Merchant Statement, Section by Section

October 9, 2026

The way to learn how to read a merchant statement is to work through it in order, starting with the summary for total card volume and total fees, then the deposits, the card-type breakdown, the interchange detail and the fee section. Divide total fees by total card volume and you have your effective rate, the single number that tells you what taking cards costs.

Every processor lays out its statement differently, so the section names below may not match yours word for word. Match each section by what it shows.

The 5 sections of a typical statement

1. Summary

The summary carries the month's totals, including gross card sales, refunds, chargebacks, net sales, total fees and the amount deposited. Write down 2 numbers here, total card volume and total fees. You need both for the effective rate.

Also note whether fees come out daily or in one monthly debit, because that changes how the deposits look.

2. Deposits

This section lists each batch and the deposit that reached your bank. Line up each business day with a batch. A missing day can mean a batch that never closed, and a late batch can cost you, since Mastercard lists the time between authorization and clearing among the requirements its interchange rates carry.

Then compare the deposits with your bank statement. The gap between sales and deposits should come down to refunds, chargebacks and, if your processor takes fees daily, the fees.

3. Card-type breakdown

Here your sales are split by card brand and type, with a count and a dollar total for each, and sometimes an average ticket. Check the split between debit and credit, and between consumer and business cards.

Debit comes in 2 kinds. Cards from banks with $10 billion or more in assets are regulated under the Federal Reserve's Regulation II, and Visa lists regulated debit at 0.05% plus 21 cents, plus 1 cent for issuers that certify they meet fraud-prevention standards. Exempt debit from smaller banks has its own rates, and Visa lists exempt debit taken at a retail counter at 0.80% plus 15 cents.

Your mix depends on how you sell. A restaurant running tipped dinner checks will show a different mix from a retail shop ringing up quick debit sales.

4. Interchange detail

On an interchange-plus statement, this section lists every interchange category your sales fell into, with the count, volume, rate and total for each. The category names come from the networks' own tables, such as Visa's CPS/Retail Key Entry or Non-Qualified Consumer Credit.

Each line reads left to right. For illustration, here is one line for keyed sales on exempt debit cards, priced at the rate Visa lists for that category.

Category	Count	Volume	Rate	Interchange
Visa CPS/Retail Key Entry, Debit	42	$1,260.00	1.65% + $0.15	$27.09

Taken in person at the counter, the same 42 exempt debit sales would fall under Visa's 0.80% plus 15 cents rate and cost $16.38, which is $10.71 less. Look for volume in the costly categories, such as key entry, card not present and non-qualified. A keyed sale that should have been dipped or tapped is a cost a working card reader fixes.

Tiered and flat-rate statements may skip this section, since GAO describes a blended rate as one that may not show interchange as a separate fee. If your statement shows qualified, mid-qualified and non-qualified rates instead, you're on tiered pricing. Our guide to interchange plus vs tiered pricing explains what that means for your costs.

5. Fees

Everything else lands here. It helps to sort each line into one of 2 groups.

Pass-through costs. Interchange and network fees, set by the card networks in their published schedules.
Processor charges. The markup, per-transaction fees, batch fees, statement fees, PCI fees, gateway fees, monthly minimums and, on tiered plans, mid-qual and non-qual surcharges. This is the group you can negotiate.

Our guide to hidden credit card processing fees covers what each processor charge is and what to ask about it.

Read the message box too. Notices about new fees or rate changes can appear there.

How to calculate your effective rate

Your effective rate is total fees divided by total card volume, times 100. Count every fee, including any billed outside the statement such as a terminal lease, so offers compare fairly.

For illustration, here is one month at a business with $48,250 in card sales over 1,930 transactions, a $25 average ticket.

Statement line (illustrative)	Amount
Total card volume	$48,250.00
Interchange	$905.60
Network fees	$86.85
Processor markup at 0.40%	$193.00
Per-transaction fees, 1,930 at $0.10	$193.00
Batch fees, 30 at $0.25	$7.50
Statement fee	$14.95
PCI non-compliance fee	$39.95
Total fees	$1,440.85

Divide $1,440.85 by $48,250.00 and you get 0.02986, an effective rate of 2.99%.

One line here is fixable without switching anything. The PCI non-compliance fee should end once you validate compliance with your processor, and without it the same month costs $1,400.90, or 2.90%.

Track the effective rate across 3 months or more. If it climbs while your card mix holds steady, the pricing changed. A few mistakes throw the math off.

Using deposits instead of card volume. Deposits are net of refunds and, on some accounts, fees, so they shrink the base and inflate the rate.
Leaving out fees billed elsewhere. A lease or gateway fee that comes out of your bank account separately is still part of the cost.
Comparing a slow month with a busy one. Fixed monthly fees weigh more when volume drops.
Comparing a quoted rate with an effective rate. An illustrative quote of 1.69% on qualified cards is one piece of the price, while the effective rate is all of it.

There's no single right effective rate. Ticket size and card mix move it, which is why a fair comparison prices your own statements under each offer. Our POS pricing page shows how the hardware and rate pieces fit together.

Red flags on a merchant statement

Mid-qual and non-qual surcharges on a big share of sales. On a tiered plan, that's where the markup grows.
A PCI non-compliance fee month after month. PCI enforcement belongs to the card brands and acquiring banks, so this is your processor's charge, and validating compliance is how you end it.
Fees with vague names. Lines like "service," "regulatory" or "misc." that don't match a network fee or a line in your agreement deserve a question.
Interchange shown only as one total. On an interchange-plus account, you should see each category.
An effective rate that keeps rising. If your card mix hasn't changed, find the fee or rate that did.
A monthly minimum charge. Your fees fell under the floor, which hits slow and seasonal months.
Lots of keyed sales. On Visa's table, an exempt debit card keyed by hand costs more than the same card taken in person. A failing card reader can be the cause.
Lease payments past their term, or for equipment you no longer use.
Any sign of a credit card surcharge program. Massachusetts bars sellers from imposing a surcharge on credit card customers under M.G.L. c.140D §28A. The hidden fees guide covers where the law stands.

What to bring to a rate review

Bring these to a rate review so the comparison runs on your real numbers.

The last 3 months of statements, every page
Your merchant agreement, pricing schedule and any amendments or change notices
Any equipment lease, with its start date and monthly payment
Gateway or online payment agreements, if you sell online or take phone orders
A rough split of in-person, keyed and online sales
The date of your last PCI self-assessment questionnaire, if you know it
The name of your POS system, and whether it lets you choose your processor

If a new system is on the table too, our Clover vs Square and Toast vs Square comparisons cover 3 common ones.
