If the bill is handled in installments, the monthly installment principal and handling fee are the same. If the total installment principal is not divisible by the number of installments, the amount will be split by rounding, and the difference will be adjusted in the last installment.

According to the bill installment, the handling fee will be 20% before the end of March. If you apply for 6 installments, the monthly handling fee rate is 0.56% of the total installment amount. If 5300 is divided into six installments, it can't be divided equally. The monthly installment principal for the first five months is 883.33, and the final installment principal is 883.35. The monthly handling fee is the same, 5300*0.56%=29.68 yuan/month, so the last month will pay: 883.35+29.68=9 13.03 yuan.
