I often hear card friends complain that the longest interest-free period of CCB credit card is not 50 days, but no matter how I swipe my card, there is only 20 days interest-free period. I wonder if CCB has made a mistake about the interest-free period? What I want to say here is that the interest-free period of credit cards in major banks is the same. Your short interest-free period is mainly due to your lack of skills in using the card. Here, I will tell you how to swipe your card to enjoy the longest interest-free period. The longest interest-free period of CCB credit card is 50 days and the shortest is 20 days, with the billing date as the watershed. If the bill is spent for one day, you can only enjoy the interest-free period of 20 days. There is a 50-day interest-free period after the bill is swiped. It's that simple. For example, suppose that the billing date of China Construction Bank is 10 every month, then: consumption on the 9th, then the repayment date is within 20 days after 10, that is to say, there is only 20 days interest-free period; 1 1, then the repayment date is within 20 days after the next 10, which means there is a 50-day interest-free period. It should be noted that the interest-free period of CCB's credit card is only for credit card consumption, excluding credit card cash withdrawal or credit card cash advance. If you use CCB's credit card to withdraw cash, the interest will be calculated at the daily interest rate, and the cardholder must pay at least the minimum monthly repayment amount, otherwise, in addition to interest, 5% will be charged as liquidated damages for the unpaid part. The above is "CCB credit card skills: how to enjoy the longest interest-free period by swiping your card". I would like to remind you that although the credit card of CCB has a maximum interest-free period of 50 days, you are advised to spend it rationally, otherwise it will be overdue and affect your personal credit record.
