There is no interest for the three-day overdue repayment of a credit card, because paying off the loan within the repayment buffer period is normal repayment, not overdue repayment, and certainly will not form a penalty interest. If the cardholder fails to repay the loan immediately on the due repayment date, he can repay the loan in full before 24: pm on the third day after the due repayment date, and ensure that it will be returned to the credit card account without any other interest. For example, if the repayment date of the user's credit card is 15th of each month, then the user can guarantee the successful repayment at 24 o'clock on the 18th of each month. The repayment buffer period is a repayment benefit given to the user by the bank, and it is not required to apply.

if the repayment is made after the repayment period, interest will be generated, and this interest does not mean that the user is several days overdue, but is calculated from the billing date of the user. If the credit card fails to repay in full beyond the due repayment date, interest will be charged from the transaction credit date, and compound interest will be charged monthly. Can credit card installment be paid off in one lump sum?

Credit card installment can be paid off in one lump sum in advance. However, whether users need to pay off their credit cards in advance mainly depends on their own requirements. If users want to repay in advance, they need to contact the online customer service of the bank in advance to stop the installment. After the installment is cancelled, the repayment business can be handled according to the steps of one-time repayment. In other words, you can choose to pay off the credit card in advance after the installment, which means paying off the full amount of the installment in one lump sum. What needs to be reminded is that early repayment of the installment bill does not mean that only the principal needs to be repaid, and some banks also need to collect liquidated damages. Moreover, after early repayment, the installment expenses paid before will not be refunded to users.
