Formula
Credit card payoff method
New balance = previous balance + monthly interest - monthly paymentThe calculator repeats this monthly balance calculation and flags payments that do not cover monthly interest.

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
- Estimating affordability, payment, payoff, interest, APR, refinance, rent, or debt scenarios before a money decision.
- Comparing terms, rates, balances, fees, taxes, insurance, debt payments, or split shares with assumptions visible.
Before relying on it
Check first
- Treating an estimate as an approval, quote, credit decision, payoff statement, tax result, or legal payment obligation.
- Leaving out fees, escrow, insurance, property tax, PMI, minimum payments, compounding, promotional rates, or local rules.
- Comparing scenarios with different time horizons, upfront costs, credit assumptions, or one-time versus monthly costs.
Details
What to know before using the result
Daily interestAPR becomes periodic
Many issuers calculate credit card interest daily, so this monthly payoff model is a planning estimate rather than a statement replica.
Payment floorMust beat interest
If the payment does not cover the interest added, the balance may not shrink and the calculator flags the plan as too low.
New chargesExcluded by default
The estimate assumes no new purchases, cash advances, fees, or APR changes while the balance is being paid down.
Benchmarks
How to read the result
Payment <= interest: Not enough.
The balance may not fall if the payment does not cover monthly interest.
Fixed payment: Predictable.
A fixed payment makes the payoff date clearer than changing minimum payments.
Extra payment: Faster 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.
