How to Use This Calculator
This calculator simulates your payoff month by month and always shows both strategies side by side: paying only the minimum versus paying a fixed amount. Enter your balance and APR, choose a payment mode, and pick the minimum-payment rule that matches your card.
Enter your Card Balance and APR exactly as shown on your statement.
Choose a Payment Mode: Minimum payment to see the trap, or Fixed amount with the monthly payment you can actually afford.
Set the Minimum Payment Rule to match your card issuer. The 2 percent or $25 option is the most common US rule.
Compare the two columns in the results. The interest-saved number is the price of staying on minimums.
The Minimum-Payment Math
Each month the card adds interest, then subtracts your payment. A 2 percent minimum shrinks as the balance shrinks, so progress slows exactly when you need it to speed up. The formula box shows the loop this calculator runs hundreds of times to reach your payoff date. If your payment is less than the monthly interest, the balance would grow forever, so the calculator requires every payment to at least cover interest plus $1.
Worked Example: The $6,500 Balance
Take a $6,500 balance at 21 percent APR. On minimum payments of 2 percent or $25, whichever is higher, the payoff takes 779 months, about 65 years. Total interest comes to about $38,496.55, so you repay $44,996.55 in all, nearly seven times the original balance. Switch to a fixed $200 a month instead: the balance clears in 49 months, total interest drops to about $3,196.49, and total paid is $9,696.49. The difference is 730 months and about $35,300 in interest, which is the cost of the minimum-payment trap on one ordinary card.
Ways to Pay Less Interest
Anything that lowers your effective rate or raises your effective payment shortens the timeline. A 0 percent balance transfer works if the 3 to 5 percent transfer fee is smaller than the interest you would otherwise pay and you finish before the promo ends. Calling your issuer to negotiate the APR sometimes works, especially with a good payment history; even a two-point cut saves thousands over a long payoff. The avalanche method, targeting the highest APR balance first while paying minimums on the rest, is the cheapest multi-card strategy. Estimates for planning only, not financial advice.
Frequently Asked Questions
How long do minimum payments take to clear a balance?
Much longer than most people expect. A $6,500 balance at 21 percent APR with minimum payments of 2 percent of the balance (minimum $25) takes about 779 months, nearly 65 years, and costs about $38,497 in interest on top of the original balance. Minimum payments are designed to keep the account current, not to get you out of debt.
What is the minimum payment trap?
The trap is that minimum payments shrink as your balance shrinks, so you pay less just when a bigger payment would help most. On that $6,500 balance at 21 percent, switching from minimum payments to a fixed $200 a month cuts the payoff from 779 months to 49 months and saves over $35,000 in interest. The comparison table above shows this math for your own numbers.
Is a balance transfer worth it?
A 0 percent balance transfer card can be worth it if you can pay the balance off within the promotional period, usually 12 to 21 months, and the transfer fee (typically 3 to 5 percent) is less than the interest you would pay otherwise. Watch out: the remaining balance reverts to a high rate when the promo ends, and new purchases often accrue interest immediately.
Should I pay the highest APR debt first?
Mathematically, yes: paying the highest-rate balance first (the avalanche method) minimizes total interest. On $6,500 at 21 percent versus smaller balances at lower rates, every extra dollar should go to the 21 percent balance first while paying minimums elsewhere. Our debt payoff planner runs this comparison for multiple debts at once.
Will paying off my credit card hurt my credit score?
Paying down a balance generally helps your score because it lowers your credit utilization ratio, which is a major scoring factor. Closing the card afterward can hurt, though, because it reduces your total available credit and shortens your credit history. Pay it off, keep the card open, and use it lightly to keep the history active.
