Frequently Asked Questions (FAQ)
What is a good annual interest rate for a credit card? A lower interest rate is always better, but most credit cards have rates ranging from 15% to 25%.
How can I lower my credit card interest rate? You can lower your interest rate by negotiating with your credit card company or transferring your balance to a card with a lower rate.
Is the APR the same as the interest rate? No, APR includes both the interest rate and any additional fees, so it may be higher than the nominal interest rate.
