How to Use the Credit Card Payoff Calculator
Enter your current credit card balance, the annual interest rate (APR — found on your statement), and your planned monthly payment. The calculator instantly shows how many months until you're debt-free, total interest you'll pay, and the minimum payment for comparison.
Try increasing your monthly payment by $50–$100 to see how dramatically that reduces your payoff timeline and total interest. This is one of the most powerful levers in personal finance.
How Credit Card Interest Is Calculated
Most credit cards compound interest daily, but our calculator uses monthly compounding which produces nearly identical results for planning purposes.
The True Cost of Minimum Payments
| Balance | APR | Payment | Months | Total Interest |
|---|---|---|---|---|
| $8,500 | 22.99% | Min (~2%) | 356 | $12,439 |
| $8,500 | 22.99% | $200 | 65 | $4,453 |
| $8,500 | 22.99% | $300 | 38 | $2,498 |
| $8,500 | 22.99% | $500 | 21 | $1,292 |
Paying minimum payments on an $8,500 balance at 22.99% APR costs $12,439 in interest over 30 years. Paying $500/month clears the debt in 21 months for just $1,292 in interest — a savings of over $11,000.
Avalanche vs. Snowball Method for Multiple Cards
Avalanche: Pay the minimum on all cards, then put extra money toward the highest-APR card. Mathematically optimal — saves the most interest. Snowball: Pay minimums on all, then attack the smallest balance first. Psychologically motivating — quick wins keep you going. Studies show both methods work; the best is whichever you'll actually stick to.
