If you don't pay your credit card balance during the grace period, you will start accruing interest on the remaining balance. The grace period is the time between the end of a billing cycle and your payment due date. Most credit cards offer a grace period of at least 21 days, during which you can pay off your balance without being charged interest. However, if you carry a balance beyond this period, interest will be applied to your remaining balance. Itit's important to take advantage of this period to avoid paying interest and fees.

Another important aspect to remember is that some credit cards do not offer a grace period at all. For example, cash advances and balance transfers often start accruing interest immediately, with no grace period. Always review your credit card terms to understand which transactions are subject to a grace period and how to avoid interest charges. Paying your balance in full every month is the best way to avoid interest and make the most of your credit cardit's grace period.
