Quick answer: Minimum payments are designed to satisfy the issuer's required payment—not necessarily to eliminate a revolving balance quickly.
Interest competes with principal
When interest is charged, part of each payment covers finance charges rather than reducing the balance. A small required payment can therefore leave a large balance working against you for a long time.
Minimums can change
Issuer formulas vary and required payments can change as the balance, interest, fees, or account terms change. Check the card agreement and statement rather than assuming a fixed percentage.
Why an extra payment matters
Money paid above the required minimum can accelerate principal reduction, which can reduce future interest when no new charges are added and the account terms stay otherwise consistent.
