Card machine fees too high? How to read what you actually pay
The only number that tells you whether card fees are too high is your effective rate: everything you paid your provider last month, divided by the card turnover you processed. Most owners quote their headline percentage when asked what they pay, and the effective rate is usually noticeably higher once terminal rental, minimum monthly charges and the extras are counted.
Work that number out from one monthly statement before comparing anything; otherwise you are comparing one quote against another with no idea what you pay today.
Where do the extra costs hide on a card statement?
Beyond the transaction percentage, UK card statements commonly carry some or all of the following. None of them show up in a headline rate, and together they are frequently where the gap between the quoted price and the effective rate comes from.
- Terminal rental, sometimes on a separate lease with its own term.
- A minimum monthly service charge that bites in quiet months.
- PCI compliance fees, plus a larger "non-compliance" charge if the annual questionnaire is not completed — completing it usually removes the bigger charge.
- Authorisation fees charged per transaction in pence, on top of the percentage.
- Higher rates on card-not-present, business and international cards than on the consumer debit rate most quotes lead with.
- Statement, gateway or reporting fees.
Why is the debit card rate quoted so low?
Because the underlying cost of consumer debit is genuinely low. Interchange, the fee set by the card schemes and paid to the cardholder’s bank, is capped in the UK for consumer cards under the Interchange Fee Regulation at 0.2% for debit and 0.3% for credit. Providers quote their most flattering rate, which sits on top of the cheapest interchange.
Business cards, international cards and online payments carry higher underlying costs and higher provider markups, and their share of your mix moves your real cost more than the headline rate does. A pricing model where those components are shown separately (interchange++) tends to suit higher-volume businesses; a flat rate is simpler and can suit lower volumes. Which is cheaper for you depends on your card mix, which is another reason the statement matters more than the quote.
What can be done without switching?
A few things are worth trying with your current provider before going to market. Complete the PCI questionnaire if a non-compliance fee is appearing, since that charge usually stops once compliance is registered. Ask for a rate review, particularly if your volumes have grown since signing, and have a competitor quote in hand when you ask. And check what the terminal rental is buying: paying an ongoing rental on hardware that is several years old is common and worth challenging.
When does switching pay?
Compare your effective rate against a quoted effective rate for the same card mix over twelve months, including any exit costs from your current contract. Where the current agreement is near its end, or was already rolling monthly, the comparison is straightforward. Where an exit fee applies, add it to the first-year cost of the new provider and see whether the saving still clears it. Our pages on cancelling specific providers and on contract exits cover the mechanics.
Frequently asked questions
What is a normal card machine fee in the UK?
There is no single normal figure, because pricing depends on turnover, card mix and pricing model. The useful measure for any business is its own effective rate: total charges on last month’s statement divided by card turnover. That number, rather than a headline percentage, is what to compare quotes against.
Why is my card machine bill higher than the rate I was quoted?
Usually because the quoted rate applies to consumer debit cards only, while business, international and online payments are charged at higher rates, and fixed charges sit on top: terminal rental, minimum monthly service charges, PCI fees and per-transaction authorisation fees. Reading one full statement line by line normally locates the gap.
What is a PCI non-compliance fee and can I avoid it?
It is a monthly charge providers apply when a business has not completed its annual PCI DSS security questionnaire. Completing the questionnaire through your provider usually stops the charge, which makes it one of the most avoidable fees on a card statement.
Are interchange fees negotiable?
No. Interchange is set by the card schemes and is capped for UK consumer cards at 0.2% for debit and 0.3% for credit under the Interchange Fee Regulation. What varies between providers is everything charged on top, which is where comparison and negotiation make a difference.
