CCB has a number of installment businesses, such as consumption installment, bill installment and cash installment. Assuming that the installment of consumption needs to be handled between consumption and two days before the latest bill date, you can choose 3, 6, 12, 18 and 24 (one month), and the corresponding handling fees are 0.7%, 0.6%, 0.6% and 0.6% respectively. (Monthly handling fee = total installment amount * handling fee rate). 50,000 yuan is divided into 12 installments, and the repayment for each installment is: 50,000 ÷12+50,000× 0.6% = 4166.67+300 = 4,466.67 yuan.
