Why the minimum payment takes so long
Card interest is charged monthly on the remaining balance. If your payment is only slightly above the interest charged, almost all of it goes to interest and the balance falls slowly. If the payment is at or below the monthly interest, the balance never declines.
Example
A $5,000 balance at 20% APR paid at $200 per month takes 33 months and costs about $1,522 in interest. Paying $300 per month finishes in 20 months with about $907 in interest. A higher payment cuts both time and cost.
Assumptions
- Fixed APR and a fixed payment; no new purchases, fees or promotional rates.
- Interest is applied monthly at APR ÷ 12. Issuers that compound daily will charge slightly more.
