When to use this calculator
Use this credit card payoff calculator when you want to estimate how long a card balance may take to repay. It is helpful for testing fixed monthly payments and seeing how extra money can reduce interest.
Formula
New balance = balance + monthly interest - monthly payment
- Balance is the current credit card amount owed.
- Monthly interest is based on the APR divided by 12.
- Payment is the fixed amount applied each month in the estimate.
Worked example
For a $6,000 credit card balance at 21.99% APR with a $250 monthly payment, the calculator estimates payoff time and total interest.
Common mistakes
- Making only small payments while continuing to use the card.
- Using the statement rate incorrectly when a promotional APR applies.
- Forgetting that late fees or new purchases can change the payoff timeline.
FAQs
Will paying more each month help?
Yes. Higher fixed payments usually reduce both payoff time and total interest.
Does this assume new purchases?
No. The estimate assumes no new charges are added to the card.
What if my payment is less than interest?
The balance may not fall meaningfully. Increase the payment or look for a lower-rate option.
