Key findings

For the average UK household credit card balance of £2,809, at the Bank of England's average rate of 21.55%, with no new spending:

  • 27 years 3 months

    to clear it paying only the minimum (interest plus 1% of the balance)

  • £4,750

    in interest on the minimum, on top of the £2,809 borrowed

  • 4 years 10 months

    if you keep paying the first minimum of £79.03 instead of letting it fall

  • £3,043

    less interest by doing that, and 22 years 5 months sooner

How the balance falls

On the minimum, the payment shrinks with the balance, so the debt falls more and more slowly. A fixed payment keeps the same pressure on the balance every month.

What this means for you

  • Don't let your payment fall. When your statement shows a lower minimum, keep paying what you paid last month. That one habit does most of the work.
  • A little extra goes a long way. Paying £129.03 a month, £50 more than the first minimum, clears £2,809 in 2 years 4 months with £786 of interest.
  • Check how your card works out the minimum. Some cards, such as new Lloyds Bank cards, ask for interest plus 2.5% of the balance. On those the same balance clears in 12 years 10 months with £1,936 of interest.
  • Stuck on the minimum? If you can only afford the minimum, free debt advice can help. See the organisations on this page.

How we worked it out

  • Balance: the average credit card debt per UK household (£2,809) and per adult (£1,444) at the end of June 2026, from The Money Charity, plus £1,000, £5,000 and £10,000.
  • Interest rate: 21.55%, the Bank of England's effective interest rate on interest-charging credit cards for August 2026.
  • Interest: added each month at the APR divided by 12, rounded to the penny.
  • Minimum payment: interest plus 1% of the balance, or £5 if that is more. This is the lowest minimum FCA rules allow (CONC 6.7.5R) and the formula Barclaycard uses. It is worked out again every month, so it falls as the balance falls.
  • Fixed payment: the first month's minimum, paid every month until the card is clear.
  • Not included: new spending, fees, late payments, promotional 0% rates and rate changes. Real lenders charge interest daily, so actual figures can differ slightly.

These are modelled estimates, not survey results or financial advice. The model is checked against our payoff calculator and lines up with The Money Charity's own estimate that a card at the average rate takes 28 years to clear on the legal minimum.

Minimum payments FAQs

How long does it take to pay off a credit card on the minimum payment?

On our figures, the average UK household card balance of £2,809 at 21.55% takes 27 years 3 months to clear on a minimum of interest plus 1% of the balance, and costs £4,750 in interest. That assumes no new spending and no fees.

Why does paying the minimum take so long?

Your minimum is worked out from your balance, so it shrinks as the balance falls. Each month most of the payment goes on interest and only about 1% of the balance is repaid, so the debt falls more and more slowly.

What is the quickest way to cut the cost?

Keep paying the same amount as your first minimum instead of letting the payment fall. In our example that is £79.03 a month, which clears the card in 4 years 10 months and saves £3,043 of interest. Paying any amount more saves more again; try your own numbers in the credit card payoff calculator.
