Most credit cards have a built-in, interest-free grace period each month, or a short period of time where no payment is yet due. If your card issuer offers a grace period, it must be for at least 21 days, thanks to the Credit Card Accountability Responsibility and Disclosure Act of 2009, more informally referred to as the CARD Act. According to the CARD Act, if your credit card issuer offers a grace period it must deliver your statement to you at least 21 days before your account’s due date. So, your grace period is the period of time between when your billing cycle ends, also known as the statement closing date, and when your payment is due. Next comes the part where you can save money and avoid paying interest on your credit card account balance. As long as you pay off your full statement balance before the end of your 21-day grace period, your card issuer won’t charge you any interest because there is no balance on which to apply an interest rate. You can find information about your credit card’s grace period in the Rates & Fees documentation that came with your card; you can also check the issuer’s website or your online banking portal for a digital copy.
