The loan interest is calculated according to the floating interest rate, and the interest is adjusted with the interest rate adjustment. Of course, no matter what the calculation method is, the interest paid will not affect, but only the adjusted interest.

After the adjustment of general bank interest rate, the interest rate of the outstanding part of the loan will also be adjusted accordingly. There are three forms:

1. After the bank's interest rate is adjusted, the newly adjusted interest rate will be implemented at the beginning of the following year (ICBC, ABC and CCB are like this).

2. Annual adjustment, that is, the new interest rate will be adjusted and implemented every year of repayment (this is the case with bank mortgage in China).

3. Both parties agree that the new interest rate level will generally be implemented in the month after the bank's interest rate adjustment.

Extended data:

The calculation formula of mortgage repayment method is divided into two types:

1, calculation formula of equal principal and interest:

Calculation principle: from the beginning of monthly contribution, the bank first charges interest on the remaining principal, and then charges the principal; The proportion of interest in monthly contributions will decrease with the decrease of remaining principal, and the proportion of principal in monthly contributions will increase with the increase, but the total monthly contributions will remain unchanged.

It should be pointed out that:

(1) The maximum amount of urban provident fund loans should be combined with local conditions.

(2) For residents who have purchased houses with loans but whose per capita area is lower than the local average, if they apply for a second set of ordinary self-occupied housing, the preferential policies for purchasing ordinary self-occupied housing with the first set of loans shall be implemented mutatis mutandis.

2, the average capital calculation formula:

Monthly repayment amount = monthly principal+monthly principal and interest

Monthly principal = principal/repayment months

Monthly principal and interest = (principal-total accumulated repayment) x monthly interest rate

Calculation principle: the amount of principal returned every month is always the same, and the interest will decrease with the decrease of the remaining principal.
