Frequently Asked Questions

Why do minimum credit card payments take decades to pay off?↓

Card issuers calibrate minimum payments (usually 1% - 2% of balance plus interest) to barely cover monthly finance charges. As the balance slowly drops, the required minimum drops too, stretching repayment across 15 to 25 years.

What is the minimum payment warning on my statement?↓

Under the Credit CARD Act of 2009, issuers must print a box showing how long it takes to pay off the balance making only minimum payments vs the payment needed to pay it off in 3 years.

Will paying off credit card debt improve my credit score?↓

Yes, significantly. Paying down balances lowers your Credit Utilization Ratio (the second largest factor in FICO scoring, accounting for 30% of your credit score).

Can I negotiate a lower APR with my card company?↓

Yes. If you have a solid track record of on-time payments, calling your card issuer to request a hardship rate reduction or promotional APR can often lower rates by 5% to 10%.
