Can a lower interest rate credit card help me save money?

Yes, a lower interest rate credit card can help you save money if you carry a balance on your credit card from month to month. With a lower interest rate, you will be charged less interest on the outstanding balance, which can reduce the overall cost of your debt. For example, if you have a $1,000 balance on a credit card with a 20% interest rate, you would be charged $200 in interest over the course of a year. But if you have the same balance on a card with a 10% interest rate, you would only be charged $100 in interest over the same period.
