Frequently asked questions
Why can a payment fail to pay off the card?+
If interest plus new charges are at least the total payment, the balance will not consistently decline.
Does this model minimum payments?+
No. It assumes a fixed monthly amount, which makes payoff timing easier to plan.
Are fees included?+
No. Late fees, annual fees, promotional APR changes, and daily interest timing can change the result.
