Formula
Each month, interest accrues on the current balance.
Payment = regular monthly payment + extra monthly payment.
Payoff occurs when the payment clears the balance plus accrued interest.
Worked example
A $12,000 card balance at 19.99% APR paid at $500/month takes about 31 months in this simplified model.

FAQ
Why does credit card payoff take so long?
High APR causes interest to consume part of each payment, especially early on.
What if the payment is too low?
If the payment does not cover monthly interest, the balance may not pay off.
Does this handle new purchases?
No. It assumes no new charges are added.
