If it is a CCB credit card, interest will be calculated at the daily interest rate of 0.5 ‰ from the transaction entry date, with the principal calculated from 40,000 until the repayment of 30,000, and the remaining 1 0,000 will continue to be calculated until the repayment.

In addition to interest, there are late fees. The late payment fee is 5% of the unpaid part of the minimum repayment amount, with the minimum 5 yuan.

Suggest returning it as soon as possible. The longer the overdue period, the greater the impact on your credit.

This is how most banks calculate credit card interest.
