The Minimum Payment Trap: Why Your Credit Card Could Take 27 Years to Pay Off

Every month, millions of UK credit card holders make just the minimum payment. It feels manageable, usually only 1 to 2.5 per cent of the balance or £25, whichever is greater. But here's the thing: minimum payments are designed to keep you in debt for as long as possible.

How minimum payments actually work

Most UK credit cards set the minimum payment at the higher of a percentage of the balance (typically 1 to 2.5 per cent) or a fixed floor (usually £25). As your balance shrinks, so does the payment. That means less and less of each payment actually goes toward reducing your debt.

On a £3,000 balance at a typical UK credit card rate of around 25 per cent APR, minimum payments of 2.5 per cent would take over 14 years to clear the debt and cost more than £3,200 in interest. More than the original balance. Let that sink in.

A real example with UK rates

Take a £2,000 balance on a card charging 22.9 per cent APR. If you pay a fixed £45 per month, you clear it in 5 years and 10 months, paying around £1,150 in total interest. Switch to minimum payments and the same debt takes roughly 28 years to clear, with total interest exceeding £4,000. That's £2,800 extra, just from how you structure the payment.

The FCA's persistent debt rules

The Financial Conduct Authority introduced persistent debt rules in 2018 (PS18/4) after finding that 2.8 million UK adults were stuck in this cycle. Under these rules, card providers must contact you after 18 months of persistent debt, defined as paying more in interest and charges than you pay off the balance. After 36 months, they must offer you a way to repay more quickly and may reduce or suspend your card.

These rules have helped, but they depend on the lender taking action. You don't have to wait 18 months to do something about it yourself.

How to escape the trap

The simplest fix is switching from percentage-based minimums to a fixed monthly payment. Even a small bump makes a huge difference. Paying £60 instead of the minimum on a £2,000 balance at 22.9 per cent APR cuts the payoff time from decades to under 4 years.
