Debt Payoff Calculator
How long could it take to pay off this balance?
Seeing how long a balance can linger, and how much interest adds up, often motivates a concrete payoff plan. Use this calculator to estimate your payoff duration. First, choose a fixed monthly payment (typical for many loans or steady card plans) or a credit card-style minimum based on a percent of the balance plus a floor.
Add an optional extra payment each month to compare how much sooner you could be done and how much interest you might avoid. Results are estimates; your issuer or lender may calculate minimums and interest differently.

Frequently asked questions
How long will it take to pay off my credit card?
It depends on balance, APR, minimum rules, and what you pay above the minimum. Use credit card mode with your issuer-style percent and floor, then add an extra payment to see how the timeline and interest change.
Why are loan and credit card modes different?
Loans usually assume a steadier required payment. Card minimums often shrink as the balance falls, which can slow payoff unless you pay a fixed amount or add extra each month.
Does fixed monthly payment include principal and interest?
Yes. Use the full amount you send each month (principal and interest together), which is what you see as your regular payment on an amortizing loan statement. This tool accrues interest on the balance, then applies your payment (plus any extra) toward what you owe.
Does this include balance transfer or promo APR?
No. This model assumes one APR for the whole simulation. For 0% promos, model those months separately or adjust APR when the promo ends.
