You can enjoy the interest-free period for credit card purchases. The interest-free period means that if you pay off all the consumption before the final payment date, you do not need to pay any interest. The interest-free period for repayment ranges from 20 to 50 days, and the length of time will depend on the specific time of your consumption. If your consumption is before the current bill date, it will be included in the current bill; if it is after the bill date, it will be included in the next bill, and you can enjoy a longer interest-free period. Assume that the bill date is the 10th and the repayment due date is the 28th. For example: Generally, if a customer consumes money on August 9th, the bill will be issued on August 10th, and repayment will be required on August 28th. Therefore, The interest-free period is the shortest; if a customer makes a purchase on August 10, the bill will not be issued until September 10. If the customer repays on September 28, there will be an interest-free period of up to 50 days. That is, if the customer repays the entire amount due before the due payment date (inclusive), the card consumption on the bill date can enjoy the longest interest-free period.
