1. Equal principal and interest repayment method: during the repayment period, the same amount of loans (including principal and interest) are repaid every month, so that the monthly repayment amount is fixed, which can control the expenditure of family income in a planned way and facilitate each family to determine the repayment ability according to their own income. Calculation formula of matching principal and interest: [loan principal × monthly interest rate ×( 1+ monthly interest rate )× repayment months ]≤[( 1+ monthly interest rate )× repayment months-1] Calculation principle: the bank charges interest on the remaining principal first, and then the principal; The proportion of interest in monthly payment decreases with the decrease of residual principal, and the proportion of principal in monthly payment increases with the increase, but the total monthly payment remains unchanged. For example, the interest rate of short-term loans (including six months) stipulated by the central bank is 5. 10%。
2. average capital repayment method: Repay the principal in equal amount every month, and then calculate the interest according to the remaining principal, so you will pay more interest at first, so the repayment amount will be more at first, and then it will be reduced every month in the following time. The advantage of this method is that because the initial repayment amount is large, the interest expense will be reduced, which is more suitable for families with strong repayment ability. Average capital calculation formula: monthly repayment amount = (loan principal/repayment months)+(principal-accumulated principal repaid) × monthly interest rate Average capital calculation formula: monthly repayment amount = monthly principal+monthly principal and interest = principal/repayment months, monthly principal and interest = (principal-accumulated repayment amount) × monthly interest rate, calculation principle: the amount of principal repaid every month is always the same, and the interest decreases with the remaining principal.
