If necessary, the following examples are introduced:

Suppose a single purchase of 2,000 yuan is repaid in 12 installments:

Interest payment in the first installment: interest = installments Balance * 12 period rate.

Monthly repayment amount = installment balance/12 (integer part)

According to the current ICBC preferential rate until the end of the year: 0.9 for 3 periods, 1.8 for 6 periods, 2.7 for 9 periods, 3.6 for 12 periods, 5.4 for 18 periods, 7.2 for 24 periods

Interest=2000×3.6=72 yuan

Repayment for each period=2000/12=167 yuan

The calculation method of the handling fee is: transaction amount × monthly rate × number of installments. Although the handling fee may be charged in a lump sum in the first period or on a monthly basis, the amount of both is the same. As repayments increase, the money owed to the bank decreases, but the handling fees will not decrease with the repayment progress. This is different from the way interest on bank loans is calculated.
