How to calculate the monthly mortgage payment?
1. repayment method of equal principal and interest: monthly payment = [loan principal× monthly interest rate× (1+ monthly interest rate )× repayment months] ([(1+monthly interest rate )× repayment months].

2. Equal principal repayment: total repayment amount = (repayment months+1)× loan amount× monthly interest rate /2+ loan amount. Matching principal repayment refers to the equal repayment of loan principal every month, and the loan interest decreases month by month with the principal. That is, the principal is distributed to each month, and the interest between the last repayment date and the current repayment date is paid off at the same time.

Will the monthly mortgage payment change?

Choose a loan with matching principal and interest. The borrower repays the loan with the same amount in each installment, including the interest and principal payable in each installment. The proportion of interest in each repayment amount decreases month by month, while the proportion of principal in each repayment amount increases month by month, that is, the monthly repayment amount remains unchanged. Choose equal principal repayment, the less monthly repayment, the different monthly repayment amount. In the first few years, the monthly repayment amount is large, and then the repayment amount will decrease month by month.

In the past, the mortgage interest rate was linked to the benchmark interest rate of the central bank. When the benchmark interest rate changes, the mortgage interest rate will also change, but it is usually adjusted at the beginning of the year, so the change of monthly repayment amount should not be obvious, and interest rate adjustment will only affect the outstanding loan interest rate.

If you buy a house with a commercial loan after June 65438+1October 65438+August, the mortgage interest rate will be changed from the previous reference loan benchmark interest rate to the reference loan market quotation rate (LPR) pricing, and the monthly quotation will be increased according to the current LPR+ regional bank benchmark, so the monthly repayment amount will definitely change.

In addition, according to the different repayment methods chosen, the monthly repayment amount will be different. For example, matching principal and interest is the same monthly repayment amount, while the monthly repayment amount in average capital is decreasing. This requires everyone to check the amount to be repaid in the current month before the monthly mortgage repayment date.
