The longest interest-free repayment period of the credit card of Postal Savings Bank is 50 days. For example, the monthly billing date is 1 per month. If you spend money by credit card on the 4th of every month, you only need to repay it before the 23rd of next month. During this period, no interest will be generated for 50 days, and personal credit records will not be affected. However, if there is an overdraft cash withdrawal transaction, you will not enjoy the interest-free repayment period.

If the interest-free installment of the credit card of the Postal Savings Bank has not been paid off, it will become overdue, and the bank will charge five ten thousandths of interest every day and compound interest every month. The interest payment time is from the bookkeeping date to the repayment date, and the interest payment principal is the actual payable amount. If there is no money to repay before the repayment date, it is recommended to apply for installment repayment in advance.
