How This Credit Card Calculator Works
Enter your current credit card balance and APR, then set your monthly payment. The calculator instantly shows you how many months until the balance is zero, how much total interest you'll pay, and the total amount paid back to the card issuer.
The vs. Minimum tab is the most eye-opening feature — it compares your chosen payment against paying only the minimum. For most balances, the difference in total interest and payoff time is shocking. A $5,000 balance at 22% APR paid at minimum takes over 20 years and costs $6,000+ in interest. Paying $300/month eliminates it in 20 months for under $1,000 in interest.
The Comparison tab shows a table and chart of different payment amounts side by side, making it easy to see exactly how much each extra dollar saves. Use the Quick Select buttons to instantly model minimum, 2× minimum, and 3× minimum payment scenarios.
Real Examples — Minimum vs. Paying More
$5,000 Balance at 22.99% APR — Minimum Only (2%)
Paying only the 2% minimum ($100 starting payment) takes approximately 257 months (21+ years) to pay off and costs over $6,800 in interest — more than the original balance. Total paid: nearly $12,000 on a $5,000 debt.
Same Balance — Paying $300/Month
At $300/month, the same $5,000 balance is gone in 20 months with only $940 in interest. That's a savings of nearly $5,900 in interest and 19 years of payments — just by tripling the minimum payment.
$12,000 Balance at 24.99% APR — Balance Transfer Strategy
Transferring $12,000 to a 0% APR card for 18 months (3% fee = $360) and paying $700/month pays off $12,600 in 18 months with $0 interest. Without the transfer at 24.99% APR paying the same $700, you'd pay $2,400 in interest and take 21 months. The transfer saves over $2,000.
Credit Card Payoff Tips
Pick one strategy and stick to it
Avalanche saves the most money. Snowball builds the most momentum. Either beats making minimum payments by years and thousands of dollars.
Pay before the statement closes
Paying before your statement closing date reduces the balance that gets reported to credit bureaus, improving your credit utilization ratio and potentially boosting your score.
Set up autopay above the minimum
Never miss a payment by automating it. Set autopay to your target monthly amount, not just the minimum — one missed payment can trigger a penalty APR of 29.99%.
Apply windfalls immediately
Tax refunds, bonuses, and gifts applied directly to credit card debt can slash your payoff timeline dramatically. A $1,500 tax refund on a $5,000 balance cuts payoff time nearly in half.
Call and ask for a lower rate
Cardholders with good payment history can often negotiate a lower APR with a simple phone call. Even a 3-5% reduction saves hundreds to thousands depending on your balance.
Stop using the card while paying it off
It's nearly impossible to pay off a card if you keep adding to the balance. Freeze the card, delete it from saved payment methods, or switch to cash/debit for daily spending.
