Frequently Asked Questions
How is credit card interest calculated?
Credit card interest is typically calculated using your average daily balance multiplied by the daily periodic rate (APR divided by 365). Most cards compound daily, meaning yesterday's interest accrues interest today. A 22% APR translates to about 0.0603% daily. On a $5,000 balance, that is approximately $91.67 in interest per month or $1,100 per year.
What is a good credit card APR?
As of 2024, the average credit card APR is around 21-24%. Excellent credit (750+) may qualify for rates of 15-18%. Good credit (700-749) typically sees 18-22%. Fair credit (650-699) often faces 22-26%. Secured cards and retail store cards may have even higher rates. The best APR is 0%, achieved by paying your full balance each month.
How can I avoid paying credit card interest?
Pay your statement balance in full by the due date each month to take advantage of the grace period and owe zero interest. If you cannot pay in full, pay as much as possible above the minimum. Avoid cash advances, which typically have no grace period and a higher APR. Consider a balance transfer card with a 0% intro rate to stop interest while you pay down existing debt.
