Introduction
If your business accepts debit or credit card payments, your merchant services statement is one of the most useful documents you have for understanding what accepting those payments is actually costing you. Unfortunately, it is not always the easiest document to understand.
Merchant statements can contain transaction rates, merchant service charges, authorisation fees, interchange fees, scheme fees, terminal charges, PCI fees, refunds, chargebacks and various other costs. Some providers show these separately, while others combine several costs into a single rate.
This can make comparing one merchant services provider with another surprisingly difficult. It can also mean the headline card processing rate you remember agreeing to does not tell you the full story about what your business is paying.
The important thing is not simply knowing what every line on the statement means. It is understanding the bigger picture: how much your business processes, what types of transactions you receive, what you are paying in total and whether your current merchant services arrangement still represents good value.
In this guide, we explain how to read a merchant services statement, the card processing fees you are likely to encounter and how to calculate the real cost of accepting card payments.
What Is A Merchant Services Statement?
A merchant services statement is a document showing your card payment activity and the charges associated with processing those transactions during a particular period.
You may also hear it referred to as a merchant statement, merchant account statement, card processing statement or merchant processing statement.
Statements are commonly provided monthly, although exactly how and when you receive yours depends on your payment provider or acquiring bank. Some are sent electronically, while many providers make statements available through an online merchant portal.
The information shown can also depend on the services you use. A business accepting card machine payments may receive different information from an ecommerce merchant using acquiring and payment gateway services.
Your merchant statement will typically show the value and volume of card transactions you have processed, together with the fees associated with them. Depending on your provider, it may also include settlements, refunds, chargebacks and a breakdown of different card types.
This makes the statement much more than an invoice from your card payment provider. Used properly, it can help you understand your processing costs, identify unusual charges and see how your transaction profile is changing.
It is also extremely useful when comparing merchant services providers. Rather than relying on an advertised rate or a quote based solely on monthly turnover, your existing statement provides a much clearer picture of how your business actually takes payments.
The difficulty is that there is no universal merchant statement format. Terminology and presentation can differ considerably between payment providers, so understanding the underlying charges is more useful than simply learning where to find a particular box on one provider’s statement.
What To Look For When You First Open Your Merchant Statement
Before getting caught up in individual fees, start with the basic information. Check the statement period, your business details and your Merchant ID, commonly referred to as your MID. You should then establish the total value of card payments processed during the period and the number of transactions involved.
Suppose your statement shows that you processed £25,000 across 1,000 transactions during the month. Your average transaction value would be £25. That already gives you useful context for analysing the charges that follow.
Check whether the £25,000 broadly corresponds with what you expected your business to process during that period. It may not match the amount deposited into your bank exactly because settlements, refunds, chargebacks, fees and transaction timings can affect the figures. However, a significant difference deserves investigation.
Next, look at how those transactions are divided. Depending on the statement, you might see UK consumer debit cards, consumer credit cards, commercial cards and international cards shown separately.
You may also be able to distinguish between card-present transactions through a card machine and card-not-present transactions, such as e-commerce or telephone payments. This transaction mix matters because £25,000 of card turnover does not necessarily cost every business the same amount to process.
A local convenience store accepting mostly UK consumer debit cards through a card machine has a very different payment profile from a B2B company accepting large commercial credit card transactions. An e-commerce business selling internationally has a different profile again.
This is one of the first principles to understand when reading a merchant services statement. Your turnover is important, but so is how that turnover is generated.
What an Acquiring Statement Looks Like
Understanding The Different Card Charges On Your Statement
One reason merchant services statements can become complicated is that not every card transaction has the same underlying cost. Your statement may separate transactions according to whether the customer used a debit or credit card. Some providers provide further breakdowns for consumer, commercial, corporate or international cards.
The exact way these appear depends on your provider and pricing structure. The mix of cards your customers use can materially affect your overall card processing costs. A pub or independent retailer receiving predominantly UK consumer debit card payments has a different transaction profile from a B2B supplier accepting significant volumes of commercial cards.
Businesses serving tourists or international ecommerce customers may have a different mix again.
Interchange is one component you may encounter when looking more closely at these costs. In a typical card transaction, several parties can be involved, including the merchant, acquiring bank, card scheme and the bank or institution that issued the customer’s card. Interchange forms part of the underlying economics of processing that payment.
There are also card scheme fees associated with networks such as Visa and Mastercard, as well as the commercial margin and other charges applied by the provider supplying your merchant services.
How clearly you see these individual components depends on your pricing model – You can read our full guide on the four pricing models of merchant services here.
With a blended or flat rate structure, several costs may be incorporated into a relatively straightforward transaction rate. With interchange-plus or interchange++ pricing, more of the underlying costs can be shown separately. This is important when comparing merchant statements because a more complicated-looking statement is not necessarily a more expensive one.
You might receive a statement containing dozens of different rates because the provider is showing individual components separately. Another provider could present a much simpler statement containing only a handful of rates.
The meaningful comparison is what all those charges add up to for the transactions your business actually processes.
Your card mix also means somebody else’s processing rate is not necessarily a useful benchmark for your business. Two companies processing exactly the same monthly turnover can legitimately have different processing costs because their average transaction values, card types, sales channels and risk profiles differ.
Understanding Your Merchant Service Charge And Processing Fees
The Merchant Service Charge, commonly shortened to MSC, is one of the most important costs to understand on your statement. Broadly speaking, it is the charge associated with processing your card transactions. Depending on your pricing structure, you may see one overall rate or several rates applying to different transaction and card categories.
For example, imagine you process £20,000 of card payments and incur £180 in core processing charges. Dividing £180 by £20,000 and multiplying by 100 gives you 0.9%.
It would therefore be tempting to conclude that accepting card payments is costing your business 0.9%. But that may not be the whole story. Elsewhere on the statement you might have another £25 in authorisation charges, £20 for terminal rental, £10 for a PCI service and £15 in other account or processing charges. Your total monthly cost has now increased from £180 to £250. Against £20,000 of card turnover, £250 represents 1.25%.
Neither calculation is necessarily wrong. They are simply measuring different things. The first tells you about a particular component of your transaction pricing. The second provides a broader view of the costs included in the calculation.
This distinction becomes particularly important when comparing merchant services quotes. A provider advertising an attractive card processing rate might charge separately for services another provider incorporates into its pricing. Likewise, a slightly higher headline rate could potentially be accompanied by fewer additional charges.
This is why businesses should look beyond the headline percentage and understand the overall cost of their merchant services package.
The Additional Merchant Services Fees Businesses Often Overlook
The headline processing percentage understandably receives most of the attention when businesses compare merchant services. However, some of the smaller charges on a merchant statement can make a surprisingly large difference over a year.
Authorisation or transaction fees are a good example. A provider may charge a small fixed amount each time a transaction is submitted for authorisation. A charge of only a few pence sounds insignificant, but transaction volume changes the picture.
If a business processes 5,000 transactions every month and pays an additional 2p per transaction, that represents £100 per month. Over a year, that is £1,200. For businesses with a high number of relatively low-value transactions, fixed per-transaction charges can therefore be just as important as percentage rates.
Card machine rental is another cost to consider. If you use physical terminals, check how much you are paying for each card machine and how many terminals are being charged to your account. Businesses with several locations or long-standing merchant services arrangements can sometimes end up paying for equipment they no longer need.
You should also establish whether your terminal agreement is with the same company that processes your card transactions. In some cases, the merchant processing agreement and equipment agreement are separate contracts. This becomes particularly important if you eventually decide to switch merchant services provider.
Minimum monthly service charges can also appear on merchant accounts. These generally mean the provider expects to receive a minimum amount in certain qualifying processing charges during the month. For example, if your minimum monthly service charge is £20 but your qualifying charges only reach £12, you may be charged the additional £8. A business consistently processing substantial card volumes may rarely be affected because its normal charges exceed the minimum. A seasonal business, new company or low-volume merchant could experience it more frequently.
PCI DSS relates to requirements for protecting cardholder information. Depending on your provider, you may pay for a PCI compliance programme or related service. However, this should not be confused with a PCI non-compliance fee. If your merchant statement contains a non-compliance charge, find out why it is being applied and what needs to be completed to resolve it. Allowing a recurring non-compliance fee to continue month after month can turn a relatively small charge into a significant annual cost.
Other statements may contain account fees, platform fees, reporting charges, paper statement fees or charges for additional services. None should automatically be assumed to be unreasonable simply because it appears separately. Equally, you should not continue paying a charge you do not understand. If you cannot explain what a fee on your merchant services statement is for, ask your provider.
Refunds, Chargebacks And Other Adjustments
Your merchant statement is not only about successful sales and card processing fees. It can also show money moving in the opposite direction. Refunds are a normal part of doing business for many merchants. Ecommerce businesses, retailers, hospitality businesses and companies accepting advance bookings may all process refunds regularly.
Your statement can help you understand both the number and value of those refunds. Depending on your payment provider and agreement, there may also be costs associated with processing them. You should also look for chargebacks.
A chargeback occurs when a card transaction is disputed and the payment is reversed through the card payment system. Depending on the circumstances and your merchant services agreement, there may also be a fee associated with handling the dispute.
One or two isolated chargebacks may not tell you very much, but a pattern deserves attention.
Increasing chargebacks can indicate problems such as customers not recognising your billing descriptor, unclear refund policies, delivery disputes, fraud or dissatisfaction with a product or service. They can also have consequences beyond the immediate loss of the transaction value.
High or increasing chargeback levels can become a concern from a merchant account risk perspective, particularly for businesses operating in sectors considered higher risk.
Your statement may also contain reversals, adjustments and other credits or debits. Understanding why these have occurred can make it much easier to reconcile your card payments with your business bank account and accounting records.
How To Calculate Your True Card Processing Cost
One of the most useful things you can do with a merchant services statement is calculate an effective card processing rate. A simple starting calculation is:
Total relevant card processing costs ÷ total card turnover × 100
Imagine your business processed £30,000 during the month and incurred £360 in the charges you have chosen to include. £360 divided by £30,000 equals 0.012. Multiply that by 100 and your effective rate is 1.2%.
The calculation itself is easy. Deciding which costs to include requires slightly more thought.
If you are trying to compare the transaction processing element of two quotes, you may decide to separate fixed equipment costs such as terminal rental.
If you want to understand the broader amount your business spends on accepting card payments, including those costs may be more useful. Neither approach is necessarily better. What matters is consistency.
If Provider A’s calculation includes terminal rental, gateway charges and account fees while Provider B’s excludes them, the resulting percentages do not provide a fair comparison. You should also be careful when comparing different months.
Suppose your turnover falls considerably during January but your fixed monthly charges remain unchanged. Your effective cost as a percentage of turnover could increase even though your provider has not changed any of its rates.
Likewise, a month containing an unusually high proportion of commercial or international cards could produce a different effective rate from one dominated by UK consumer debit transactions.
This is why several months of merchant statements are often more useful than one statement when assessing your card processing costs.

SEND US YOUR STATEMENTOnline Payment Gateway Charges Need To Be Included Too
Merchant statements can become slightly more complicated for businesses accepting payments online because the acquiring cost may only represent part of the total expense.
An e-commerce business may have an acquiring relationship for processing card payments and a separate payment gateway providing the technology required to securely transmit payment information.
Depending on the arrangement, payment gateway charges might appear alongside your other processing fees or be invoiced separately. This means an acquiring statement viewed in isolation may not reveal the full cost of accepting payments online.
For example, you might pay an acquiring rate on each card transaction, a gateway charge per transaction and a monthly gateway fee. Your e-commerce platform may also have its own payment-related charges depending on the system and setup you use.
When reviewing online payment costs, you therefore need to bring these elements together. If you process £50,000 of e-commerce payments and your acquiring statement shows £400 in charges, it would be misleading to assume your total payment cost is 0.8% if another £150 is being paid separately for your payment gateway.
The same principle applies when comparing a new online payment provider.
Find out whether the quoted price includes both acquiring and payment gateway services, what fixed fees apply and whether particular transaction types attract additional charges.
This is particularly relevant for subscription businesses, international e-commerce merchants, companies accepting multiple currencies and businesses using more sophisticated payment gateway features.
Understanding Your Merchant Services Pricing Model
Before comparing your merchant services statement with another quote, it helps to understand how your current pricing is structured. Some businesses use relatively simple blended or flat-rate pricing. Instead of seeing each underlying component separately, the merchant pays a broader rate covering particular transaction types.
Other businesses use interchange-plus or interchange++ pricing, where underlying components are shown separately and the payment provider’s own margin may be more visible. Neither should be judged purely by appearance.
A flat rate might be easy to understand, but simplicity does not automatically mean it is cheaper. Interchange based pricing can look considerably more complicated on a merchant statement but may provide greater visibility over where the money is going.
Your own transaction profile determines what matters. If your business processes high volumes of relatively straightforward UK consumer card transactions, one pricing structure may suit you particularly well. If you have a complicated mixture of international, commercial, online and face-to-face transactions, the comparison requires more detail.
You should therefore avoid taking a single transaction from your statement, comparing its percentage with an advertised rate and deciding that one payment provider is cheaper.
Merchant services pricing needs to be assessed across the transactions your business actually processes.
How To Compare Merchant Services Statements And Quotes Properly
When comparing merchant services quotes, your existing statement is the best place to start. Monthly turnover alone does not tell the full story. Transaction volumes, average transaction value, card mix and how you accept payments can all affect your overall costs.
Look beyond the headline processing rate and compare the complete picture, including transaction and authorisation fees, card terminal costs, payment gateway charges and any other recurring fees. Contract length, settlement times, support and the functionality you need should also be considered.
Payments World can do this comparison for you if you simply follow this link.
We work with more than 25 acquiring banks and payment providers, so we can review your existing merchant statement and compare suitable options based on how your business actually takes payments.
The aim is not simply to find the lowest advertised rate. It is to find out whether you can reduce your overall payment costs while still getting the right payment setup for your business.

Signs Your Merchant Services Costs Are Worth Reviewing
Finding additional charges on your merchant statement does not automatically mean you are being overcharged. Merchant services legitimately involve a number of different costs. There are, however, situations where reviewing your arrangement makes sense. One of the biggest is business growth.
If you originally agreed your merchant services rates when processing £5,000 per month and now process £50,000, the commercial profile of your business has changed substantially.
Rates agreed when you were smaller may no longer be the most appropriate available to you.
The same applies if your transaction profile has changed. Perhaps you started with one card machine but now operate several locations. Maybe your business has moved heavily into ecommerce, your average transaction value has increased or you now accept significantly more international payments.
Your payment arrangement should suit the business you operate today. You should also investigate recurring charges that you do not recognise, unexplained increases in fees, terminals you no longer use, repeated PCI non-compliance charges or significant differences between the rates you believe you agreed and those appearing on your statements.
Another obvious reason for a review is simply time. If you have been with the same merchant services provider for several years and have never compared the market, there is little harm in understanding what alternatives are available.
That does not mean you should automatically switch. If your current provider offers competitive pricing, reliable service and everything your business needs, remaining where you are may be the right decision.
The purpose of reviewing a merchant statement is not to manufacture a reason to change provider. It is to make sure you understand what you are paying and can make that decision based on evidence.
How Often Should You Check Your Merchant Statement?
You do not need to conduct a full merchant services market comparison every month, but you should get into the habit of looking at your statement. A quick monthly review can help you identify unexpected fees, changes in card turnover, unusual refund activity, increasing chargebacks and discrepancies that might otherwise go unnoticed.
Every few months, look at the broader trend.
Has your effective processing cost changed? Are you processing more transactions? Has your average transaction value moved significantly? Has your business become more reliant on e-commerce? Are international or commercial cards becoming a larger proportion of your turnover?
These changes can affect whether your existing merchant services arrangement remains suitable. A more detailed review is particularly worthwhile when your contract is approaching renewal, your turnover has increased significantly, your business model has changed or you are considering a new payment provider.
Businesses routinely review insurance, utilities, banking costs and other major suppliers. Card processing costs deserve the same attention.
How Payments World Can Review Your Merchant Statement
Merchant services quotes are much easier to compare when they are based on what your business actually processes.
Rather than starting with an advertised rate, Payments World can review a recent merchant statement to understand your current card turnover, transaction volumes, average transaction value, card mix and the different fees you are paying. If you take payments online, we can also factor in gateway costs and other charges that may sit outside your main merchant account.
We can then compare that existing setup with suitable options from the acquiring banks and payment providers we work with. Crucially, the comparison is based on your real processing profile, so you can see how the alternatives stack up against what you are actually paying today.
That might uncover unnecessary costs, a pricing structure that no longer suits your business or an opportunity to secure better rates. It might also show that your existing deal is already competitive.
Either way, you come away knowing what the numbers on your statement actually mean and whether there is a genuine reason to consider changing anything.
Conclusion: Your Merchant Statement Tells You More Than A Headline Rate
Merchant services statements are complicated because card processing itself involves several different costs. The mistake is assuming that the biggest percentage on the page tells you everything you need to know. It doesn’t.
Your real payment costs are shaped by your processing rates, transaction volumes, card mix, fixed fees, terminal charges and, for some businesses, payment gateway costs. Once you understand how those pieces fit together, your statement becomes much more useful. It gives you a benchmark.
You can see what accepting card payments actually costs your business today, track whether those costs are changing and properly assess any new merchant services quote you receive. Instead of comparing headline rates, you can compare what matters: the total cost of processing the transactions your business actually takes.
That does not mean the cheapest option will always be the right one. Reliability, settlement, support, payment technology and contract terms all matter too. But understanding your statement means you can make that decision with the full picture in front of you.
So, the next time your merchant statement arrives, don’t just file it away. Take a closer look at what you processed, what you paid and whether the numbers still make sense for your business. And if you want to know how your current deal compares with the wider market,

Frequently Asked Questions
FAQs
A merchant services statement is a record of your card processing activity and the charges associated with your merchant account. Depending on your provider, it can include card turnover, transaction volumes, processing fees, settlements, refunds, chargebacks, terminal costs and other merchant account charges.
A useful starting point is to divide your relevant card processing costs by your total card turnover and multiply the result by 100. For example, £300 of relevant costs against £25,000 of card turnover produces an effective rate of 1.2%. When comparing providers, make sure you include the same types of charges in each calculation.
The percentage you were quoted may only represent part of your overall merchant services costs. Depending on your agreement, you may also pay fixed transaction or authorisation fees, card terminal charges, gateway fees, PCI-related charges and other account costs. Looking at your full statement rather than one headline rate provides a more accurate picture.
Yes. If you already accept card payments, Payments World can review a recent merchant statement to understand your current processing profile and costs. We can then compare suitable merchant services options from the providers we work with and explain whether there is an opportunity to improve your current arrangement.
