Instalment payment mainly has handling fees, not interest.
Let me give you an example. Suppose you bought an IP6 and spent 6,000. You can apply for CCB’s consumption installment, which means that after consumption, your single payment will be fully charged two days before the bill date. You can apply for installments for consumption of 1,000 yuan, which is applied per transaction. Suppose you applied for 6 phases and your application was successful. Then the first installment amount will be settled on your latest bill date, installment amount = 6000/6 = 1000, the installment fee for each installment is 6000*0.6=36, and the total installment amount for each installment is 1000 36= 1036. After the bill is settled, the total repayment amount and the minimum repayment amount will be written clearly on the bill. If you repay in full and on time, you can enjoy the interest-free period for installments and consumption. If you fail to repay the loan in full and on time, interest will be accrued on the full amount at 50,000 per day from the date of entry into the account, as is the case with consumption.
