How to calculate the monthly repayment amount after the adjustment of mortgage interest rate?
After the mortgage interest rate is adjusted, the monthly repayment amount should be calculated according to the loan interest rate type.
If you choose to adjust to a fixed interest rate, the loan interest rate from the loan date to the maturity date is fixed and does not change with the adjustment of LPR;
If you choose to adjust to the floating interest rate of LPR, on each repricing date (65438+1 October1or every month of the loan issuance date), the loan interest rate will be recalculated and determined according to the LPR+ value of the corresponding period in the latest month, and will remain unchanged for a repricing period (generally one year).
Determine whether the loan interest rate changes, and then look at the choice of mortgage repayment methods.
In the case of equal principal repayment, monthly repayment amount = (loan amount/loan months)+(loan amount-cumulative repayment) monthly interest rate;
In case of equal repayment of principal and interest, monthly repayment amount = loan amount, monthly interest rate (1+ monthly interest rate), repayment months ][( 1+ monthly interest rate), repayment months-1.
Among them, the monthly interest rate of fixed-rate mortgages remains unchanged; The monthly interest rate of LPR floating rate mortgage changed on the repricing date. The calculation method of monthly mortgage repayment amount is complicated. If you want to get the calculation result more simply, you can calculate it through the mortgage calculator.
