A grace period is the stretch of time between the end of your credit card billing cycle and your payment due date. If you pay your full statement balance within that window, you owe no interest on your purchases. It is one of the most valuable features of a credit card — and it is easy to lose track of.
How the grace period works:
- Your billing cycle closes and a statement is generated showing the balance you owe.
- You then have until the due date — by law, at least 21 days — to pay.
- Pay the full statement balance by the due date, and purchases that cycle cost you nothing extra.
How you can lose the grace period: if you carry a balance — pay less than the full amount — you typically lose the grace period. New purchases then begin accruing interest right away, and the grace period is usually only restored after you pay the balance in full and stay current.
Important exception: grace periods generally apply only to purchases. Cash advances and balance transfers usually have no grace period — interest starts on the transaction date.
The takeaway: treat the statement balance as the amount to pay, not the minimum, and pay it by the due date every cycle to keep your purchases interest-free.
