Why does credit card interest feel so expensive?

Credit cards often have high APRs, and interest accrues on the remaining balance. Paying only the minimum can extend payoff timelines for years and increases total interest substantially.

What happens if my payment is too small?

If your payment does not cover the monthly interest, the balance can grow over time. Increasing your payment is the fastest way to reduce interest and payoff time.

Is it better to pay off the highest APR or smallest balance first?

Paying the highest APR first typically minimizes total interest. Paying the smallest balance first can create quick wins that help you stay motivated.

Does balance transfer change the payoff timeline?

It can. A lower promotional APR reduces interest during the promo period, which can speed up payoff. Be sure to include balance transfer fees and what the APR becomes afterward.
