In detail: Credit Card Payoff Calculator for a £4,000 Balance at 20% APR
A £4,000 balance at 20% APR is costing you around £800 per year in interest alone — that's money going to the lender instead of reducing the debt. Credit-card APRs compound monthly, so the effective rate is slightly higher than the headline.
20% is around average for UK credit cards. Whether a balance transfer makes sense depends on the transfer fee — usually worth it if you can clear the balance inside the 0% window.
The minimum-payment trap: most cards require only 1% of balance + interest as the minimum. On £4,000 that's around £107/month — which takes 15–20 years to clear if you pay only the minimum. Paying a flat amount well above the minimum is the single biggest lever you have.
