Calculate credit card payoff timelines.
Months to payoff is derived from the card balance, APR, and fixed monthly payment using the amortization equation.
A $5,000 balance at 20% APR with $200/month payments is paid off in about 33 months.
The calculator shows total interest, which falls sharply as the monthly payment rises above the minimum.
The avalanche (highest APR first) saves the most interest. The snowball (smallest balance first) can be easier to stick with psychologically.
No. Adding new charges while paying down the balance extends the timeline beyond the estimate.
