1, equal principal and interest repayment method monthly payment = [loan principal × monthly interest rate ×( 1+ monthly interest rate) repayment months ]=[( 1+ monthly interest rate) repayment months-1], equal principal and interest repayment method means that the principal and interest are the same every month and are repaid every month.
2. Average repayment method: monthly repayment amount = (loan principal ÷ repayment months)+(loan principal-accumulated repaid principal) × monthly interest rate. Matching principal repayment means that the principal repaid every month is unchanged and the interest is decreasing by stages.
Taking mortgage as an example, according to the benchmark interest rate of the central bank, the annual interest rate of commercial loans over five years is 4.90%; The annual interest rate of provident fund loans for more than five years is 3.25%, and the monthly loan for 30 years is 3 million (i.e. 360 installments), which is calculated as follows:
I. Commercial loans
1. Matching principal and interest repayment method: 30-year loan of 3 million yuan, monthly payment of 1592 1.8 yuan.
2. The average capital repayment method is 3 million yuan, and the first monthly payment in 30 years is 20,583.33 yuan, and it will decrease every month thereafter.
Second, provident fund loans.
1. Matching principal and interest repayment method: 30 years, 3 million loan monthly payment 1056+09 yuan.
2. Average capital repayment method: the first monthly payment of a 30-year 3 million loan is 16458.33 yuan, and then it will decrease every month.
