1, equal principal and interest repayment method, that is, the borrower needs to repay the same amount of loan principal and interest every month, in which the monthly loan interest is generally calculated according to the remaining loan principal at the beginning of the month and settled monthly.

2. Average capital repayment method, that is, the borrower needs to repay the loan principal of the same amount (loan amount/loan months) every month, and the monthly loan interest is generally calculated according to the remaining loan principal at the beginning of the month and settled every month, and the sum of the two is the monthly repayment amount.

Average capital and calculation of average capital

1, repayment method of equal principal and interest:

Monthly payment = [monthly interest rate of loan principal (1+ monthly interest rate) repayment months ][( 1+ monthly interest rate) repayment months-1] monthly interest payable = monthly interest rate of loan principal [( 1+ monthly interest rate) repayment months-(/kloc-)

Monthly principal repayment = monthly interest rate of loan principal (1+ monthly interest rate) (repayment month serial number-1)[( 1+ monthly interest rate) repayment months-1] Total interest = repayment months, monthly contribution-loan principal.

2, the average capital repayment method:

Monthly payment = (the number of months to repay the loan principal)+(the loan principal-the accumulated repayment amount of the principal);

Monthly interest rate Monthly repayable principal = Monthly repayable interest of loan principal = Monthly interest rate of remaining principal = (loan principal-accumulated repaid principal amount) Monthly decreasing amount of interest rate = Monthly repayable principal monthly interest rate = Monthly repayment months of loan principal;

Monthly interest rate Total interest = (total repayment months+total repayment monthly interest rate)+total repayment months (1+ monthly interest rate).
