Credit Card Payoff Calculator
Credit card payoff planning
This calculator is for revolving credit card debt. It applies monthly interest, subtracts the payment, and repeats until the balance reaches zero. If the payment does not cover monthly interest, it warns instead of inventing a payoff date.
Worked example
With a $6,200 balance, 22.99% APR and a $300 payment, the tool compares the current payment with $350 and $400 payments. The comparison shows months saved and interest saved, which is often more useful than the payoff month alone.
Methodology
Monthly interest is approximated as APR divided by 12. The model assumes no new purchases, no late fees, no annual fees, no promotional-rate expiration and a fixed monthly payment.

Frequently asked questions
What if my payment is too low?
The calculator shows a warning when the payment does not cover estimated monthly interest, because the balance would not amortize.
Does this include new purchases?
No. It assumes no new charges and a fixed APR.
Should I use snowball or avalanche next?
Use snowball to organize debts by balance and avalanche to organize debts by APR.
