1. Minimum repayment amount. Interest is divided into two parts. The first part is interest = total bill × daily interest rate × the number of days from the day of transaction to the day before the minimum repayment; The second part of interest = unpaid amount × daily interest rate × the number of days from the date of repayment of the minimum repayment amount to the day before the debt is paid off; Interest = the first part of interest+the second part of interest.

2. Cash advance for repayment. Interest = total cash advance × daily interest rate × the number of days from the date of cash advance to the day before debt payment.

3. Overdue repayment. Interest = overdue amount × daily interest rate × the number of days from the transaction day to the day before the debt is paid off.

4. Cash interest. If you withdraw 1, yuan and repay it after 1 days, the interest will be 1,× .5 %× 1 = 5 yuan.

5. installment interest. If you apply for installment payment or repayment by installment, for example, in three installments with the installment amount of 1 yuan, the interest will be 1×.85%×3=25.5 yuan.
