The so-called full interest, that is to say, whenever the cardholder fails to pay off the debt in full, no matter how much the cardholder repays, the interest-bearing part is the full amount of the debt. To put it simply, you owe the bank 10 yuan, and you paid it back to 6 yuan, 4 yuan on the repayment date. You think the interest-bearing part should be 6 yuan, but in fact the interest-bearing amount of the bank is 10 yuan.

2. Banks generally use cyclic interest calculation.

The so-called cyclic interest calculation means that every consumption on the bill, including the unpaid amount of last month, starts from the bookkeeping date (usually the second day of credit card consumption) and charges five ten thousandths of interest every day until the day when partial repayment is received first; Then continue to calculate the interest according to the remaining unpaid part until the next repayment, and so on.

It is worth noting that the interest is calculated from the date of consumption.

At present, the interest rate of overdue repayment of credit cards in all banks is the same, which is five ten thousandths of the daily interest, and the compound interest is calculated monthly. Interest calculation time: calculate interest from the day of consumption!
