Shortened grace periods Most credit cards offer a 25-day grace period to pay for new purchases without incurring interest charges. Recently, some banks have shortened the grace period to 20 days for customers who pay their bill in full. If this applies to you, ask your bank to return your card to the twenty-five day grace period. If you don't pay your bill by the specified due date, the bank will backdate your interest charges. This means it'll charge you interest from the day a charge is posted to your account, not from the day payment was due.
Some banks even charge interest from the date of purchase.
If you can, pay the amount balance in full. If not, make an effort to maximize your payment by the due date. Adjusted balances Be aware of how long your introductory low rate lasts. When the low rate period expires, your existing balance will be subject to much higher interest rates. If you can afford to, pay the amount owing in full or at least minimize your balance before the rate increases.
