The calculation of loan interest adopts floating interest rate, and the interest is adjusted with the adjustment of interest rate. Of course, no matter how it is calculated, it has no effect on the interest paid. Will have an impact on the adjusted interest. After the adjustment of the general bank interest rate, the interest rate of the outstanding part of the loan is also adjusted. There are three forms: first, after the bank's interest rate is adjusted, the newly adjusted interest rate will be implemented at the beginning of the following year (ICBC, Agricultural Bank of China and China Construction Bank are all like this); The second is annual adjustment, that is, the new interest rate is adjusted and implemented every year of repayment (such is the case with China bank mortgage); Third, the two sides agreed that the new interest rate level will generally be implemented in the month after the bank's interest rate adjustment.

No matter how the benchmark interest rate is adjusted, the floating (or falling) range remains unchanged, but it is only floating (or falling) on the basis of the new interest rate.
