Important Notes & Limitations
Interest rates are modeled on a monthly compounding basis. Assumes no new purchases, transaction fees, late penalties, or promotional APR expiration during the payoff period.

Frequently Asked Questions
Your payoff timeline depends directly on your balance, APR, and monthly payment amount. Paying only the minimum payment (often 1-2% of balance plus monthly interest) can take 10 to 25+ years because principal reduction is minimal. Increasing your monthly payment by even $50 to $100 dramatically slashes total interest and shortens the repayment period by years.
Credit card issuers calculate daily interest using the Daily Periodic Rate (DPR = APR ÷ 365) multiplied by your average daily balance, then sum these charges across the monthly billing cycle (approximately APR ÷ 12 each month). Any portion of the monthly payment that exceeds the accrued interest directly lowers your principal balance.
Yes, unequivocally. Paying only the required minimum prolongs repayment and maximizes the bank's interest profit. Every dollar paid above the monthly interest charge goes 100% towards reducing your principal, compounding your future interest savings each billing cycle.
The debt avalanche method prioritizes extra payments toward the card with the highest APR, minimizing total interest paid across all cards. The debt snowball method prioritizes paying off the smallest balance first, providing psychological and motivational milestones to maintain momentum.
If your monthly payment does not exceed the monthly interest charge (negative amortization), your balance will continue to grow over time rather than decrease, resulting in endless debt accumulation.
