I calculated an account, assuming that this month's bill amount is 10000 yuan, the bank bill is divided into six installments, and the corresponding handling fee rate is 0.75%, so the handling fee for each installment is 75 yuan, and the total repayment amount for each installment is 174 1.67 yuan; But using the repayment APP, the same 10000 yuan will be repaid in six installments. According to its calculation formula, the total monthly repayment amount is 17 1 1.27 yuan. Compared with the bank, it can save 30.4 yuan per period, 6 periods 182.4 yuan. However, it is a personalized interest calculation, which is a localized improvement of this business in China. According to your actual credit situation, everyone's interest calculation method is slightly different.
