The repayment method is as follows:

Minimum repayment amount in the first month: 10%, namely 1700 yuan;

The remaining amount shall be paid off in 12 installments: the principal of each installment is15300/12 =1275 yuan, and the repayment fee of each installment is 15300*0.6%=9 1.8 yuan.

Add the two together, and the total amount you should pay back each period is:1275+91.8 =1366.8 yuan;

2. If it is cash withdrawal, you can't apply for installment repayment. There is no interest-free period for cash withdrawal, and interest is calculated at 0.5 ‰ of the cash withdrawal amount every day.
