How Much Does Only Paying the Minimum Actually Cost You?
Why paying only the minimum on a credit card can take years and cost more in interest than the original balance, with the math behind why minimum payments are structured that way.
Credit card minimum payments are typically set as a small percentage of the balance (often 1-3%) plus that month's interest charge — a structure designed to keep the account current, not to pay off the balance in any reasonable timeframe.
Why minimums barely move the balance
On a high-interest card, a large share of every minimum payment covers interest that accrued that month, leaving only a small remainder to reduce the actual principal. As the balance slowly drops, the minimum payment (recalculated as a percentage) drops too — which means the payoff drags on even longer, since a shrinking payment fights an almost-as-large ongoing interest charge.
What changes the outcome
- Any fixed extra amount added every month, rather than letting the payment shrink alongside the balance
- Paying more than the recalculated minimum even as it drops
- Stopping new charges on the card while paying down the existing balance
