Let's take a look! \ r \ nHow to calculate the mortgage interest rate \ r \ nThe mortgage interest rate is a kind of principal interest paid by the buyers according to the interest rate stipulated by the bank, and the calculation formula is principal × interest rate × deposit period (time). There are two kinds of mortgage interest rates, one is equal principal and interest, the other is average capital, and the mortgage interest rate will be different because of different mortgage repayment methods. \ r \ Let's talk about the loan interest rate again. It is the ratio between the interest amount and the principal amount during the loan period. We all know that the domestic interest rate is managed by the People's Bank of China, and the interest rate determined by the People's Bank of China can only be implemented after the approval of the State Council. The loan interest rate determines the profit distribution ratio between the borrowing enterprise and the bank, and also affects the economic interests of both borrowers and lenders. The loan interest rate will vary according to the type and duration. The following are two formulas for calculating the mortgage interest rate: \r\n 1, and the formula for calculating the equal principal and interest \r\nEqual principal and interest means that the bank receives the interest of the remaining principal first, and then the principal. However, the interest will decrease with the decrease of the remaining principal in the monthly payment, and the proportion of principal in the monthly payment will increase with the increase. The most important point is that the total monthly contribution remains unchanged. \ r \ nNote: The amount of provident fund loans in cities is high, which should be considered in combination with local conditions. If you have borrowed money to buy a house, but the per capita area is lower than the local average, you can apply for a second suite with preferential policies. \r\n2. Calculation formula of average capital \ r \ nMonthly repayment amount = monthly principal and interest; Monthly principal = principal/repayment month; \ r \ Monthly principal and interest = principal-total accumulated repayment) X monthly interest rate. \ r \ The principle is that the principal returned every month is always the same, and the interest will decrease with the decrease of the remaining principal. \ r \ Editor's summary: The above is a brief introduction to the mortgage interest rate algorithm, and some small partners may not know it very well.

Calculation formula of interest: interest = principal × interest rate × deposit period (time).

Mortgage interest is a kind of principal interest that buyers borrow from banks and pay at the interest rate stipulated by banks. The calculation of mortgage interest of different lenders will be different.

According to the different repayment methods of mortgage, the calculation of mortgage interest can be divided into two calculation methods: equal principal and interest and average principal.

Extended data:

1, repayment method of equal principal and interest:

Matching principal and interest repayment method is to repay the loan principal and interest with matching principal and interest every month.

The calculation formula is as follows:

Average monthly repayment amount = (loan principal × monthly interest rate × (65438+1October 65438+1October interest rate) Total repayment periods-1.

2, the average capital repayment method:

The average capital repayment method is to allocate the loan principal to each repayment period by means of decreasing repayment, and the interest payable in each period is calculated from the time when the principal is never repaid, and the principal amount in each period remains unchanged, and the interest is gradually decreasing.

The calculation formula is as follows:

Monthly (quarterly) repayment amount = loan principal/repayment times (loan principal-accumulated amount of repaid principal) × monthly (quarterly) interest rate.
