How Credit Card Interest & Payoff Traps Work
Credit card companies typically set minimum monthly payments between 1% and 2.5% of the balance plus accrued monthly interest. Because the principal reduction is tiny, high APRs (often 20% to 29%) cause compounding interest to swallow most of your payment each billing cycle.
The Power of Even $50 to $100 Extra
Every dollar you contribute above the required minimum payment goes 100% directly toward reducing your principal balance. By shrinking the principal immediately, next month’s interest charge drops, compounding your debt elimination speed.
Frequently Asked Questions
Credit cards use Daily Periodic Rate (DPR = APR / 365). Interest is accrued daily on your average daily balance and billed each month.
If you have good credit, a 0% APR promotional balance transfer card (usually lasting 12 to 21 months) can save hundreds in interest, provided you account for the 3% to 5% transfer fee and pay the balance off before the promotional rate expires.
