The Real Cost of Credit Card Debt

The Minimum Payment Trap

Minimum payments (typically 2–3% of balance or £25, whichever is higher) are designed to maximise interest paid. A £3,500 balance at 22.9% APR with minimum payments can take 20+ years to clear and cost over £3,000 in interest alone.

The Interest Formula

Monthly interest = Balance × (APR ÷ 12 ÷ 100). On a £3,500 balance at 22.9%, that's £3,500 × (22.9/12/100) = £66.79 in interest the first month alone. Paying only the minimum barely dents the principal.

Fastest Payoff Strategies

Avalanche method: pay minimums on all cards, put all extra money toward the highest APR card. This minimises total interest paid. Snowball method: target the smallest balance first for psychological wins. Both work — the best strategy is the one you'll stick to.
