Why credit card interest adds up so fast
Card APRs are among the highest of any consumer debt — often 18%–29%. Because interest compounds monthly on the remaining balance, a large share of a small payment goes straight to interest, which is why minimum payments can stretch a balance over many years.
How paying more changes everything
Raising your monthly payment shortens the payoff time disproportionately, because more of each dollar attacks the principal. Even an extra $50 a month can cut years off the term and save hundreds or thousands in interest.
The minimum payment trap
If your payment barely exceeds the monthly interest, the balance falls painfully slowly; if it’s below the interest, the balance actually grows. This calculator flags when a payment is too low to make progress.
