Should I switch card payment provider?

Switching is worth it when the annual saving clears the cost of leaving, and that is a different sum from comparing two headline rates. This works out what you actually pay now as an all-in effective rate, compares it against an indicative band taken from published UK headline rates, then nets the difference against your exit fee and remaining contract to give a breakeven in months. It is arithmetic on your figures, not a quote and not a promise that anyone will accept you.

What you pay now

Defaults to the median published headline rate on our panel. The band runs 1.5% to 2.5%.

Your all-in effective rate now-
Annual cost of acquiring now-
Annual cost at the compared rate-
Indicative annual difference-
Breakeven after exit costs-

Not included, and they matter: any bespoke rate you could negotiate by staying, hardware buyout or return costs, interchange differences on your actual card mix, and whether a new acquirer would accept you at all. Nothing here is a quote, a saving you are guaranteed, or a statement that an exit fee can be negotiated away.

Indicative only. Published headline rates are not the rate any particular business is offered.

Where this calculation misleads
“A headline rate comparison flatters switching, because the number you are comparing against is a published rate for a business that may look nothing like yours. Two things move the real answer more than the percentage does: your card mix, since a debit-heavy ledger and an AMEX-heavy one price very differently on the same headline, and whether your current provider will simply match the offer if you ask. The cheapest switch is often the one you do not make, after using the quote to renegotiate. Treat the breakeven here as the threshold a genuine offer has to clear, not as a saving you have already made.”

What this tool tells you

It nets the saving against the cost of leaving, which is the step most comparisons skip. For the rate itself in isolation, use the effective rate calculator; for the full annual picture, the total cost of acquiring calculator. If the reason you are leaving is not price, start from what is happening with your current provider, because a frozen account or a termination is a different problem from an expensive one.
