Question 1

Why minimum payments are a trap

Accepted Answer

Minimum payments are set low — often just above the interest — so most of the payment barely touches the balance. A card paid at the minimum can take a decade or more and cost more in interest than the original purchases.

Question 2

The payment has to beat the interest

Accepted Answer

If your monthly payment is less than the interest charged that month, the balance grows no matter how long you pay. The calculator flags this — the fix is always to pay more than the monthly interest, ideally a lot more.

Question 3

A worked example

Accepted Answer

A $5,000 balance at 21% APR paid at $200 a month clears in about 32 months with roughly $1,400 in interest. Raise the payment to $300 and it’s gone in under 19 months with far less interest — every extra dollar goes straight at the principal.

Question 4

Common mistakes

Accepted Answer

Paying the minimum and assuming you’re making progress; adding new spending to the card while paying it down; and chasing rewards on a card you carry a balance on — the interest dwarfs any cashback.
