Browser-based

Estimate how long it takes to pay off credit card debt from your balance, APR, and monthly payment—or find the payment needed for a target timeline. See total interest, total amount paid, and a first-month principal and interest breakdown.

Assumes a fixed APR and steady monthly payment without new charges. Promotional rates, fees, and daily compounding may change real payoff timing.

What to do next

How to use this tool

1. Enter current balance and APR. 2. Choose monthly payment or target payoff months. 3. Click Calculate payoff. 4. Review months to debt-free, total interest, and the payoff timeline chart. 5. Compare scenarios with higher payments to see interest saved.

Worked example

Example: a $5,000 balance at roughly 18% APR with about $200/month often takes roughly two to three years to pay off with interest in the low thousands of dollars—minimum-payment schedules usually take longer.

How it works

Enter your credit card balance, APR, and either a fixed monthly payment or a target payoff timeline. The calculator applies monthly interest to the remaining balance and estimates how long payoff takes, total interest paid, and the first-month principal versus interest split. Minimum-payment rules and promotional rates are not modeled.

Limitations

Assumes a fixed APR and steady monthly payment without new charges. Promotional rates, fees, and daily compounding may change real payoff timing.

Frequently asked questions

What calculation modes are available?

You can enter a fixed monthly payment to see how long payoff takes, or enter a target timeline in months to see the required monthly payment.

What happens if my payment is too low?

If the monthly payment does not cover interest, the balance never decreases and the calculator shows an error instead of a payoff timeline.

Does this include fees or promotional rates?

No. Results are estimates based on balance, APR, and your payment plan. Fees, minimum-payment rules, and promotional rates are not included.
