The normal interest rate of credit cards is between one point two and one point five, and each bank is different. Moreover, the interest rate of the same bank is not static and fluctuates according to different time periods. If it is divided into three parts, 6,000 yuan will be divided into six installments, and the handling fee for each installment is 39 yuan, plus the principal 1039 yuan. The total interest of the six installments is 234 yuan, and the total repayment amount plus the principal is 6234 yuan. In addition, in order to show that credit cards are interest-free and attract more people to spend, banks like to call credit card interest a handling fee, which is actually a truth. The handling fee is interest, and making a mark is also a chastity archway.
