Headline rate vs effective rate
The 'rate' quoted in a sales conversation is almost always the headline consumer debit rate. It's the cheapest line on the price list and applies to a slice of your transactions, not the whole picture.
The number that actually matters is the effective rate: every card fee on your statement divided by your total card turnover. It includes scheme fees, authorisation fees, monthly account charges and any other recurring costs.
The cost pattern changes by business type
High street retail
Often weighted towards in-person consumer cards. Check card mix, terminal rental and authorisation charges.
Hospitality
Lower average transaction values can magnify per-item charges. Check device count, tipping, settlements and business-card mix.
E-commerce
Online pricing can include fixed per-transaction amounts, gateway charges and different domestic or international rates.
B2B and professional services
Higher transaction values may come with a heavier commercial and corporate-card mix, which sits outside consumer interchange caps.
Mobile and on-the-go traders
Pay-as-you-go pricing can reduce fixed commitment. Compare it with a tailored quote at your actual monthly volume.
Blended pricing vs Interchange Plus
Blended pricing groups all card types into one or two rates. It's simpler to read but hides where the cost is going.
Interchange Plus shows the underlying interchange and scheme fees passed through at cost, plus a transparent provider margin. For businesses with reasonable volume or a high share of commercial cards, it can work out cheaper - but only if the margin is fair.
Neither model is automatically better. The right answer depends on your card mix and how much transparency you want.
How to sense-check your own rates
Pick your most recent statement and calculate the effective rate. Then apply the same card turnover, card mix and transaction count to every complete written quote.
If the quoted total differs, identify what explains it: transaction pricing, terminal rental, monthly fixed fees, authorisation charges, settlement or contract terms. This is more dependable than comparing against a generic range.
A free, independent statement review will do this for you - we look at the same numbers and explain them in the context of your statement.
What has changed since 2020
Post-Brexit scheme fees have risen materially on UK-EU card transactions. Regulated consumer interchange remains capped at 0.2% (debit) and 0.3% (credit), but Visa and Mastercard have added granular assessment, cross-border and authorisation fees on top.
How those costs appear depends on the pricing model and provider. If your arrangement has not been reviewed for some time, recalculate the effective rate from a current statement rather than assuming the original quote still describes the total.
Key takeaways
- Compare effective rates, not headline rates. The headline number rarely reflects what you actually pay.
- There is no single reliable UK effective-rate benchmark; use your own card mix and complete quotes.
- Terminal hire, monthly account fees and authorisation fees often explain more of a high rate than the transaction percentage itself.
- Older arrangements are worth recalculating because pricing components and the business itself may have changed.
