How Your Credit Card Grace Period Works and How to Use It

Think of your credit card grace period as a small window of time between when your statement ends and your payment due date. If you pay your full balance by the due date, you won't pay interest on new purchases. To use it, always check your statement closing date and then pay before the due date. This works only if you paid the previous month's bill in full too. Miss that and interest kicks in immediately on new charges.
