Next, we will focus on the interest rate of bank loans for housing calculation for more than 5 years and the corresponding two methods. Under the following circumstances, the loan amount is 10000, the loan term is 5 years, and the annual interest rate of the loan is 6.55%:

Method 1: Repay the principal and interest in equal amount, that is, add the total interest due within the bookkeeping time to the total principal, and then repay it in equal amount every month. That is, the total monthly repayment amount is the same.

The monthly repayment amount is: [principal x monthly interest rate x( 1+ monthly interest rate) loan months ]/[( 1+ monthly interest rate) repayment months-1].

That is,10000 * (6.55%12) * (1+6.55%/12) * 60/(1+6.55%//kloc-0.

Method 2: Matching principal repayment is to allocate the principal to each month (the principal payable every month is the same), and then add the interest payable every month. There are a lot of initial repayments, which will decrease in a certain proportion every month, but the pressure of repayment in the early stage is too great and it is relatively easy in the later stage.

According to the average capital, the monthly payable principal is10000/512 =166.

Then the monthly interest payable:

The interest for the first month is 10000 (total amount owed) *(6.55%/ 12) (note: monthly interest rate) =54.58.

The interest for the second month is (10000-166) * (6.55%/12) = 53.67.

Then the monthly repayment amount is the monthly principal of the cinema (i.e. 166)+ the monthly interest payable.

As the remaining amount is reduced every month, the monthly payable amount is also reduced every month.
