There is no interest on the credit card installment of China Merchants Bank, but a certain handling fee is required. Handling fee = installment amount * installment number * installment rate. Different credit card installment types have different installment numbers and rates. According to the relevant regulations of China Merchants Bank, the handling fees corresponding to different installment numbers range from 0% to 1.67%. Suppose that the installment amount of a user's credit card bill is 10000 yuan, and the payment is made in 9 installments, and the rate of 9 installments is 0.82%, then the installment fee = 10000*0.82%*9=738 yuan.
