1. After the credit card is repaid according to the minimum repayment amount, the remaining unpaid amount will be automatically accumulated to the next credit card billing date. It should be noted that

although the bank does not charge a late fee for repayment according to the minimum repayment amount, it will generate revolving interest (that is, rolling interest). After paying the minimum repayment amount on the billing date, the bank will consider that you have completed the repayment this month. The interest on the remaining unpaid part will be calculated from the last accounting day before repayment (usually the second day after consumption), and the interest will be accumulated from the accounting day for every consumption afterwards. That is to say, if the arrears of the last consumption are not paid off before the next consumption, the interest generated will be accumulated to the interest of all unpaid parts, and the monthly compound interest will be generated until it is fully paid off.

2. The calculation formula of monthly compound interest is as follows:

Monthly compound interest = interest of total consumption+interest of unpaid part.

For example, if the billing date of each month is 1th, and you spend money in 1 yuan on November 11th, 2 yuan on November 18th and 5 yuan on November 2th, and the minimum repayment amount is 125 yuan on the next billing date, it will be deemed that you have repaid this month, and the interest generated will be calculated at 1125 per day from the 21st. Then the interest shall be repaid on the next repayment date (***2 days): 18.75+11.25=3 yuan.

Third, different bank credit card repayment standards are also different. If the cardholder fails to pay off all the loans at one time by the specified repayment date, he can make repayment according to the minimum repayment amount specified by the issuing bank. The minimum repayment amount is the minimum guarantee to maintain a good credit record. The minimum repayment amount stipulated by the general bank is about 1% of the consumption amount plus other scattered expenses. Therefore, after the credit card is repaid according to the minimum repayment amount, the bank does not give a clear answer to the repayment time of the remaining unpaid part, and it can be paid off in one lump sum on the next credit card billing date, or it can always be repaid according to the minimum repayment amount on the credit card billing date. If only the minimum repayment amount is paid every time, the minimum repayment amount will be higher and higher, the interest will roll more and more, and the repayment pressure will be greater. From the perspective of financial management, the sooner you pay off the arrears, the more you will save money.
