If you swipe 2,500 yuan with a CCB credit card and apply for business in three installments, the handling fee rate for each installment is: 0.7%.
Monthly repayment: handling fee 2500X0.7% + principal 2500÷3=17.5+833.33=850.83 yuan.
The minimum repayment is 3 months, and the monthly principal repayment is 2500÷3+2500X0.5‰X30 days=833.33+37.5=870.83
