How Does Credit Card Interest Work?
Credit card debt is one of the most expensive forms of consumer debt due to high annual percentage rates (APR) that typically range from 18% to 29%+. Credit card companies calculate interest on a Daily Periodic Rate (DPR) by dividing your APR by 365 days, and then multiplying that rate by your average daily balance.
Daily Periodic Rate (DPR) = APR ÷ 365Monthly Interest Charge ≈ Current Balance × (APR ÷ 12)Number of Months to Pay Off Debt (N):
N = − [ ln(1 − (Balance × Monthly Rate ÷ Payment)) ] ÷ ln(1 + Monthly Rate)
Why the "Minimum Payment Trap" is Financially Dangerous
Credit card issuers usually set minimum monthly payments between 1% to 3% of your outstanding balance plus accrued interest (or a flat $25–$35 minimum). When you only pay the minimum:
- Up to 80% of your payment goes toward interest fees rather than reducing your principal balance.
- As your balance slowly decreases, your minimum required payment also decreases, stretching your repayment over 15 to 25+ years.
- On a $6,000 balance at 22% APR, paying only minimums can end up costing you more than $8,500 in interest alone — more than double the original money borrowed!

Frequently Asked Questions
As much as your monthly budget allows. Even paying a flat $100 to $200 extra per month above the minimum can save you thousands of dollars in interest and cut your repayment timeline by 10 to 15 years.
This causes negative amortization. If your monthly payment does not cover the accrued monthly interest charge, the unpaid interest is added to your principal balance. Your balance will grow every month even though you are making payments, and the debt will never be paid off.
Yes, significantly. Your Credit Utilization Ratio (the percentage of your credit limits you are using) accounts for 30% of your FICO credit score. Lowering your utilization below 30% (and ideally below 10%) will rapidly boost your credit score within 1 to 2 billing cycles.
If you qualify for a fixed-rate personal debt consolidation loan at a lower rate (e.g. 9%–12% APR vs 24% credit card APR), it can substantially lower your monthly payment and total interest. However, you must avoid running up new charges on your zeroed-out credit cards.
