Frequently asked questions
- How is credit card payoff time calculated?
- Using the amortization formula: months = -log(1 - balance * monthly_rate / payment) / log(1 + monthly_rate). Each month, interest accrues on the remaining balance, and your payment reduces it.
- What if my payment is less than the monthly interest?
- If your payment is less than or equal to the monthly interest charge, your balance will never decrease. You must pay more than the monthly interest to make progress.
- How can I pay off my card faster?
- Increase your monthly payment, make extra lump-sum payments, or transfer the balance to a lower-rate card. Even small increases in your monthly payment can cut months off your payoff timeline.
