Frequently Asked Questions

How long will it take to pay off my card?
It depends on the balance, the APR and your monthly payment. The number of months is n = −log(1 − balance × i ÷ payment) ÷ log(1 + i), where i is the monthly interest rate (APR ÷ 12).
Why won’t my balance go down?
If your monthly payment only covers the interest, the balance never falls. Your payment must exceed the monthly interest (balance × APR ÷ 12) for the debt to reduce at all.
