Frequently Asked Questions
How long will it take to pay off my card?
It uses your balance, interest rate and monthly payment to estimate the months to zero and the total interest cost.
Why does paying only the minimum cost so much?
Minimum payments barely cover interest, so the balance shrinks slowly and you pay far more over many years.
How much do extra payments help?
Even small extra amounts go straight to principal, cutting both the payoff time and total interest substantially.
