Credit Card Payoff Calculator

Credit Card Payoff Calculator

This calculator shows exactly how long it will take to pay off your credit card balance and how much total interest you will pay. Enter your current balance, APR, and monthly payment to see your payoff timeline and the true cost of carrying credit card debt.

How Credit Card Payoff Is Calculated

Each month, interest accrues on the remaining balance: Monthly Interest = Balance x (APR / 12). Your payment first covers that interest, and only the remainder reduces the principal. The calculator iterates month by month until the balance reaches zero. For example, on a $5,000 balance at 22.99% APR, the first month’s interest alone is $95.79, so a $200 payment only reduces the principal by $104.21.

Example

Key Factors That Affect Payoff Time

• APR — the average U.S. credit card APR is around 22-25%; even a few percentage points mean hundreds more in interest
• Monthly payment — paying only the minimum (typically 2% of balance) can stretch payoff to 15-30 years
• Balance size — larger balances generate more monthly interest, meaning a smaller fraction of your payment goes to principal
• Additional charges — adding new purchases while paying off increases the balance and extends your timeline
• Balance transfer offers — a 0% introductory APR can eliminate interest temporarily, accelerating payoff dramatically

Tips

1. Pay more than the minimum — doubling a $200 minimum payment to $400 on a $5,000 balance can save over $700 in interest and cut payoff time in half
2. Target the highest-APR card first (avalanche method) to minimize total interest paid across multiple cards
3. Look into balance transfer cards with 0% introductory APR offers to pause interest for 12-21 months
4. Set up autopay for more than the minimum to avoid late fees and ensure consistent progress
