The small print, explained
Card Processing Charges Explained
Merchant statements can make simple card payments look complicated. This guide explains the charges UK businesses commonly see and why the full cost matters more than the headline rate.
The useful detail
Clear answers for busy business owners.
The effective rate
Your effective rate is the total cost of taking cards divided by your card turnover. It is more useful than looking at one percentage because it includes the smaller charges and fixed fees that can change the real cost.
Common statement charges
A statement may show a mix of percentage charges, per-transaction fees and fixed monthly lines. The exact names vary by provider, but these are the areas worth understanding.
- PCI compliance or non-compliance fees
- Dashboard, statement or reporting fees
- Authorisation and declined-transaction fees
- Secure processing or account service charges
- Card-not-present rates for phone and online payments
- Scheme fees and the provider mark-up
- Terminal rental and minimum monthly service charges
Card mix changes the answer
Debit, credit, business, rewards and overseas cards can carry different underlying costs. A business taking mostly UK consumer debit cards may have a different profile from a dealership taking high-value corporate or credit-card payments.
Blended versus interchange-plus
Blended pricing puts the costs into one headline rate. Interchange-plus separates the underlying interchange fee, Visa or Mastercard scheme fee and the provider mark-up. Neither model is automatically better. The useful question is what the complete cost looks like for your own turnover and card mix.
The contract matters too
A fair comparison includes the contract length, renewal date, termination terms and auto-renewal wording. A small rate saving can be outweighed by a long commitment, a separate rental invoice or a charge you did not know was there.
No pressure. Just a clearer view of what your payment setup is doing.
