CCB's credit card has a number of installment businesses. Take the consumption installment as an example, it needs to be processed from the time of consumption to 2 days before the latest billing date. You can choose 3 installments, 6 installments, 12 installments, 18 installments and 24 installments (one installment per month), and the corresponding handling fees are .7%, .6%, .6% and .6% respectively. (Monthly handling fee = total installment amount * handling fee rate).

if 4 is repaid in three months, the repayment amount of each period is: 4 ÷ 3+4× .7% = 1333.33+28 = 1361.33 yuan. Among them, 28 yuan is the monthly installment fee.
