Minimum Payment Trap Calculator

The minimum payment trap is when you only pay the lowest amount required each month. Because most of that payment goes toward interest rather than your balance, the debt barely shrinks. You end up paying for years — sometimes decades — and give the bank far more than you originally borrowed.

With a typical APR of 20–25%, most of your minimum payment goes straight to interest. Only a small amount reduces your actual balance. The next month, interest is calculated on almost the same balance — so the cycle repeats. The lower the payment relative to the interest, the longer the trap lasts.

On a typical credit card balance of £3,000 at 22.9% APR, you could end up paying for over 25 years and hand the bank more than £2,500 in interest — nearly doubling what you originally owed. Use the calculator above to see your exact numbers.

Even paying £20–£50 more than the minimum each month can cut years off your payoff time and save hundreds in interest. Use the slider in the calculator above to see exactly what an extra amount does to your timeline.

Paying the minimum keeps your account in good standing. However, carrying a high balance relative to your credit limit raises your credit utilisation, which lowers your score over time. Paying more reduces utilisation and improves your score.

The two proven strategies are the Avalanche method (highest APR first — saves most interest) and the Snowball method (smallest balance first — builds momentum). Either beats minimum payments by years. Try our AI Debt Payoff Planner to build your exact strategy.

If your payment is less than the monthly interest charge, your balance grows every month even though you are making payments. This is called negative amortisation and is a debt emergency. Increase your payment above the monthly interest immediately and contact a free debt charity for advice.

UK providers calculate minimum payments as a percentage of your outstanding balance (usually 1–3%) or a fixed floor (often £25), whichever is higher. As your balance goes down, your minimum goes down too — extending your repayment even further.

Yes. Call your credit card provider and ask — especially if you have a good payment history. Alternatively, a 0% balance transfer card moves your debt to a new card with no interest for an introductory period, meaning every payment goes directly toward your balance.
