The installment fee rate of China Merchants Bank's credit card is related to the number of installments. The longer the installment time, the lower the fee rate. At present, China Merchants Bank offers seven installments, namely, installment 2, installment 3, installment 6, installment 10, installment 12, installment 18 and installment 24, and the corresponding handling fees for each installment are 1.0%, 0.9%, 0.75% and 0.7 respectively. Handling fee per installment = total installment principal × handling fee rate per installment corresponding to the number of installments. After the bill installment business application is successful, the handling fee will be credited to the RMB account of the credit card in installments. The repayable principal of each installment of the bill is equal to the total installment principal divided by the number of installments. The principal payable in each installment (accurate to the minute) is credited to the cardholder's credit card account every month, and the balance is credited to the last installment.

5,000 yuan will be repaid in installments. If the repayment is made in six installments, and the handling fee rate of each installment is 0.75%, then the handling fee of each installment = 5,000 * 0.75% = 37.5; The principal payable in each installment =5000/6=833.33 yuan; Total amount to be repaid in each period =37.5+833.33=870.83 yuan.
