Credit card payoff
Months to pay off26 months
Monthly payment used: $250.00.
Interest paid$1,358.22
Estimated interest if you make the same payment every month.
Total paid$6,358.22
Original balance plus estimated interest.
What the payoff estimate assumes
This keeps the payment fixed at $250.00 per month and applies interest monthly at the APR entered. If the payment does not cover monthly interest, the balance keeps growing.

Calculator use
Best for
- Quick months to pay off from card balance, apr and monthly payment.
- Personal finance scenarios before changing a budget, loan, savings goal, or purchase plan.
- Monthly cash flow, affordability, debt payoff, or future-value estimates.
- Assumption checks before talking with a lender, tax preparer, employer, or financial professional.
Before relying on it
Check first
- Entering card balance, apr and monthly payment from different time periods or scenarios.
- Mixing gross income, take-home income, one-time costs, and monthly costs in the same comparison.
- Forgetting taxes, fees, insurance, irregular bills, or minimum payments when using an estimate.
- Treating a planning estimate as a quote, tax filing result, approval decision, or guaranteed return.
Benchmarks
How to read the result
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions.
Payment <= interestNot enough
The balance may not fall if the payment does not cover monthly interest.
Fixed paymentPredictable
A fixed payment makes the payoff date clearer than changing minimum payments.
Extra paymentFaster payoff
Even small extra payments can reduce payoff time and interest.

FAQ
Common questions
How do I calculate credit card payoff time?
Apply monthly interest to the balance, subtract the payment, and repeat until the balance reaches zero.
Why does APR matter so much?
Higher APR adds more monthly interest, so less of each payment goes toward principal.
What if my payment is too low?
If the payment does not cover the monthly interest, the balance can keep growing.
Should I stop using the card while paying it off?
For a clean payoff estimate, assume no new charges. New purchases add balance and can change the payoff date.
