At present, many credit cards do not occupy the quota by stages. For example, if you spend 12000 and divide it into 12 installments, once the installment application is successful, except for the current amount occupied by 1000+ handling fee, other amounts above 10000 can be used normally.

The simplest explanation of revolving interest is that cardholders who repay their debts with the minimum repayment amount cannot enjoy the "interest-free period" treatment. Generally, from the date of consumption, the bank will charge overdraft interest at the rate of five ten thousandths per day until it is paid off.

Except for ICBC, most domestic banks will still calculate overdraft interest according to the original credit card amount, even if the money has been paid off, it will be counted as interest. What is even more frightening is that if the cardholder still fails to pay off the debt next month, this part of interest will be included in the minimum repayment amount, usually compounded monthly.
