Your credit score takes into account how much available credit you're using. Paying a credit card balance in full 10 days or one day ahead of the due date won't help your utilization ratio and thereby improve your score. That strategy doesn't work because the balance of the account has already been reported to the credit agency, says Ulzheimer.
However, if you pay the balance in full before the statement closing date, which appears on your statement, then your report will post a zero balance for that account. That will help your utilization rate, or how much credit you are using, along with your credit score, says Ulzheimer.
To get started, you will have to pay one credit card bill earlier than usual and then consider your statement date as your due date, says Ulzheimer. Also, you will need to check your balance online or over the phone to make sure you pay the correct amount.
