Payoff Time Formula:
From: | To: |
This calculator estimates how long it will take to pay off a credit card balance when making fixed monthly payments, taking into account the interest charges.
The calculator uses the following formula:
Where:
Explanation: The formula calculates how many months it will take to pay off the balance by accounting for the decreasing principal and compounding interest each month.
Details: Understanding your payoff timeline helps with financial planning, shows the true cost of carrying a balance, and can motivate debt repayment strategies.
Tips: Enter your current credit card balance, your fixed monthly payment amount, and the card's annual percentage rate (APR). All values must be positive numbers.
Q1: What if my payment is too low to pay off the balance?
A: The calculator will show "Never" if your payment doesn't cover the monthly interest (payment ≤ principal × monthly rate).
Q2: Does this account for minimum payments?
A: No, this assumes fixed payments. Minimum payments typically extend payoff time significantly.
Q3: How accurate is this calculation?
A: It's mathematically precise for fixed payments and rates, but actual results may vary if your APR changes.
Q4: Should I include new purchases in this calculation?
A: No, this assumes no additional charges. For accuracy, stop using the card while paying it off.
Q5: How can I pay off my card faster?
A: Increase monthly payments, make biweekly payments, or transfer to a lower-interest card.
