Rate refers to the installment fee rate of the credit card corresponding to the number of periods, and the percentage of several periods refers to the percentage of installment fee rate. Installment fee = total installment amount * installment fee rate.

For example, if a credit card costs 2000 yuan, the three-phase installment fee rate of China Merchants Bank credit card is 3.5%, and the three-phase installment fee rate of ICBC credit card is 1.3%, then:

China Merchants Bank credit card installment fee = total installment amount * installment fee rate =2000*3.5%=70 yuan.

China Industrial and Commercial Bank credit card installment fee = installment total amount * installment fee rate =2000* 1.3%=26 yuan.
