You are divided into 12 periods.

The repayment amount of each installment is 4500/ 12=375 yuan, and the installment fee is about 20-30 yuan.

You only need to pay back 395-405 yuan per installment. This is the approximate repayment amount, depending on the information on your bill. If there is other consumption, other consumption is not included in the installment and needs to be repaid separately. You'd better pay according to your bill.

Also, after the installment, your available amount will be restored with your installment repayment.
