How to use the Credit Card Payoff Calculator
- 1Enter your card balance and its APR.
- 2Choose to pay a fixed amount per month, or to be debt-free by a target number of months.
- 3See the payoff time, total interest and how a bigger payment changes things.
Why minimum payments keep you in debt
Credit card interest is charged monthly on the remaining balance. With APRs often above 20%, paying only the minimum means most of each payment goes to interest, and a few thousand dollars can take over a decade to repay. Paying a fixed, higher amount each month shortens that dramatically.
Strategies that work
Avalanche: pay extra on the highest-APR card first (saves the most interest). Snowball: pay off the smallest balance first (quick wins keep you motivated). A 0% balance transfer card can also help if you can repay within the promo period.
Example: paying off $5,000 at 22.9% APR
Small increases in your monthly payment make a huge difference:
| Monthly payment | Time to pay off | Total interest |
|---|---|---|
| $125 | 77 months (6.4 years) | $4,530 |
| $150 | 54 months | $3,022 |
| $200 | 35 months | $1,860 |
| $300 | 21 months | $1,076 |
| $500 | 12 months | $602 |
Should I consolidate?
A personal loan or a 0% balance transfer card can lower your interest if you qualify and stop using the old card. Watch for balance transfer fees (often 3–5%) and make sure you can repay before the promotional rate ends.
Frequently asked questions
How is credit card interest calculated?
Most cards charge interest daily or monthly at APR ÷ 365 or APR ÷ 12 on your balance. This calculator uses monthly compounding, which is very close to what issuers charge.
What if my payment is too low?
If your payment does not cover the monthly interest, the balance never goes down. The calculator will warn you and show the minimum needed.
