How to read a merchant statement, line by line

This is the main guide in Reading statements. Every guide in the series is listed at the end.

A merchant statement looks like a wall of codes, small print and percentages. It does not have to be. Almost every statement, from every provider in every country, is built from the same handful of parts. Once you know what those parts are and where they sit, you can read any statement in about five minutes.

This guide walks through the parts in the order you should read them. It uses one worked example with real arithmetic, shows you the formula that matters most, and ends with a checklist for catching what a statement leaves out. If you are a payment consultant, the same method is the first half of a savings quote.

What exactly is a merchant statement?

A merchant statement is the monthly summary your card payment provider (the acquirer or the company reselling its service) sends you. It lists the card payments you took, the fees charged on them, and the total you owe or that was taken from your account.

Providers call it different things: a processing statement, a statement of fees, an invoice, or a monthly summary. The names change but the job is the same. It is the only document that shows what accepting cards really cost you last month.

Two things make statements hard to read. Fees are often grouped under different names, so the same charge can appear as a "service fee" at one provider and a "processing fee" at another. And many statements leave something out: an extra bill for the terminal, a charge billed on a separate invoice, or a rate that is shown but never explained.

Step 1: Find the period, the merchant and the provider

Start at the top of the first page. Confirm the billing period (usually one calendar month), the business name and address, and the merchant or terminal ID. If you are reading a statement for someone else, check these match the business you think you are analysing.

Note who actually issued the statement. The brand on the page is not always the company that processes the payments. A reseller may sit in front of an acquirer, and some businesses pay two companies: one for the processing and another for the terminal.

Step 2: Read the turnover and the transaction count

The turnover is the total value of card payments processed in the period. The transaction count is the number of payments. Together they give you the average transaction value, which is turnover divided by transactions.

Look for these figures near the top or in a summary box. Then check two things:

• Whether the turnover is gross (before refunds) or net (after refunds). Your effective rate looks better on gross turnover and worse on net, so use the same basis every time you compare.
• Whether the turnover is split by card type. A breakdown by debit, credit, commercial and international cards tells you far more than a single total.

The average transaction value matters because many fees are charged per transaction. A business with an average sale of £8 feels a 10p per-transaction fee very differently from a business with an average sale of £80.

Step 3: Work out which pricing model you are on

This is the step most people skip, and it decides how you read everything after it. Providers use four common models, and the statement layout changes with each one.

If you cannot tell which one applies, count the lines. A statement with dozens of lines and card-type labels such as "consumer debit" or "commercial credit" is almost always interchange plus. A statement with two or three lines is blended or flat. We cover the differences in full in our guide to interchange plus, blended and flat rate pricing.

Step 4: Add up every fee line

Now go through the fee section line by line and write down each charge. Fees on a merchant statement fall into five groups, whatever the provider calls them.

1. Interchange fees. Paid to the bank that issued the customer's card. Set by the card schemes and, in some countries, capped by regulation. This is usually the largest cost.
2. Scheme (or assessment) fees. Paid to Visa, Mastercard and other card networks for using their rails.
3. Acquirer or processor markup. The provider's own margin, shown as a percentage, a per-transaction fee, or both.
4. Fixed monthly fees. Terminal rental, gateway fees, statement or account fees, PCI compliance fees and any minimum monthly service charge.
5. Occasional fees. Chargebacks, refunds, authorisation fees, early termination or paper statement fees.

Put them in a simple list with the amount next to each. If a fee is shown as a rate (for example 0.30% of £4,000), do the multiplication yourself and check it matches the amount printed. Mistakes and mismatches here are common enough to be worth the thirty seconds.

In this example the provider's own markup (£72.00) is slightly larger than the interchange paid to card issuers (£70.00). That is not unusual on small accounts, and it is exactly the kind of thing a statement hides when it shows only a blended rate.

Step 5: Calculate the effective rate

The effective rate is the only number that lets you compare two different statements fairly. It turns a pile of rates, per-transaction fees and monthly charges into one percentage.

For the example above: £209.00 divided by £20,000 is 0.01045, so the effective rate is 1.045%, or about 1.05%. Use all fees, including fixed monthly charges and any fee billed on a separate invoice. Leaving them out is the most common way to make a provider look cheaper than it is.

Our full guide to the effective rate covers edge cases, such as refunds and annual fees, but the formula never changes.

Why a small turnover pushes the rate up

Fixed monthly fees do not shrink when you take less. Spread over a low turnover they add a lot to the effective rate, and over a high turnover they add very little. Using the same fee structure as the example (variable costs of roughly 0.87% plus £35.00 of fixed fees), the effective rate changes like this.

This is why a business taking £2,000 a month can pay more than twice the effective rate of one taking £20,000 on an identical price list. It is also why comparing headline rates alone, without monthly fees, can point you to the wrong provider.

Step 6: Check the total against what was charged

This final check catches more problems than any other. Find the total fees on the statement, then compare it with the amount that actually left your bank account for card fees.

If the two figures do not match, one of four things has happened:

• A second invoice exists, often for the terminal or a gateway, and is billed by a different company.
• A fee has been added after the statement was generated, such as a late payment or non-compliance charge.
• VAT, sales tax or another tax is on one figure but not the other.
• There is a genuine billing error.

In the example, if £209.00 is the statement total but your bank shows £245.00 debited, the extra £36.00 deserves an explanation before you do anything else. A calculator with a bill check, like the checkmyrates calculator, flags this difference automatically.

A quick way to read the statement: the flow

If you only remember one thing from this guide, remember the order. Reading a statement the same way every time is what makes you fast and keeps you from missing things.

What if the statement is incomplete?

Many statements hide the one number you need. Perhaps the rate is shown without the turnover, or the fees are shown without the rate. You can often rebuild the missing piece from the other two.

• If you have fees and turnover but no rate, divide fees by turnover.
• If you have the rate and turnover but no fee, multiply them.
• If you have the rate and the fee but no turnover, divide the fee by the rate.

These checks only work for a single fee line at a time, so apply them line by line. The calculator on this site has built-in tools for each of these cases, because incomplete statements are the norm rather than the exception.

What should you check on every statement?

Use this list the next time you open a statement. A "no" to any line is a reason to look closer.

• Is the billing period, business name and merchant ID correct?
• Is turnover shown, and is it gross or net?
• Are transactions split by card type (debit, credit, commercial, international)?
• Can you tell which pricing model applies?
• Does each percentage fee multiply out to the amount shown?
• Are all fixed monthly fees listed, including terminal, gateway and PCI?
• Is there a minimum monthly charge, and has it been triggered?
• Does the total on the statement match the amount debited?
• Is there any separate invoice for hardware or services on the same account?
• Does the statement name the contract end date or notice period anywhere?

How do consultants turn a statement into a quote?

Reading a statement is the first half of the job. The second half is showing the business what a different set of fees would have cost them over the same month, with the same turnover and the same card mix. That side-by-side view is what a merchant remembers, because it uses their own numbers.

If you do this for a living, build a habit of recording the effective rate, the monthly fixed fees and the total difference every time. A clean, repeatable read is the foundation of an honest savings proposal, and it protects you if the merchant asks how you got there. Our guide to analysing a statement in five minutes covers the working method in more detail.

Frequently asked questions

What is a merchant statement?

A merchant statement is the monthly summary from your card payment provider. It shows how much you took in card payments, the fees charged on them and the total cost. Some providers call it a processing statement, a statement of fees or an invoice.

Where do I find my merchant statement?

Most providers publish statements in an online portal, and many also email a PDF each month. If you cannot find yours, ask your provider's support team for the last three months, and check whether a separate company bills your terminal.

What is a good effective rate?

There is no single good rate, because it depends on your turnover, your average transaction value, your card mix and where you operate. A business that takes mostly consumer debit cards will pay less than one that takes mostly commercial or international cards. Compare your rate with your own earlier statements and with quotes on the same turnover and card mix, not with a number from a blog.

Why is the total on my statement different from what I was charged?

The usual causes are a separate invoice for a terminal or gateway, a fee added after the statement was generated, or tax shown on one figure and not the other. Ask your provider for a breakdown of every charge on the account for that month.

What is the difference between interchange and scheme fees?

Interchange is paid to the bank that issued the customer's card. Scheme fees are paid to the card network, such as Visa or Mastercard. Both are passed on to you, either as separate lines (interchange plus pricing) or hidden inside a single blended rate.

How often should I review my merchant statement?

Check every statement quickly against your last one, and do a full review at least once a year and before any contract renewal. A rise in effective rate with no change in your sales mix is a good reason to ask questions.

Figures in this guide are examples to show the method. Fees, rules and rates change, so check your own statement, contract and current rules before you decide. This is general information, not financial or legal advice.
