In loans, we often use the calculation method of average capital and equal principal and interest:
Calculation formula of average funds: monthly repayment amount = (loan principal ÷ repayment months)+(principal-accumulated amount of repaid principal) × monthly interest rate;
Calculation formula of equal principal and interest: monthly repayment amount = loan principal × [monthly interest rate× (1+monthly interest rate) repayment months]/{[(1+monthly interest rate) repayment months]-1}.
Supplementary information:
Matching principal and interest repayment means that the buyer repays the same amount of loans every month during the repayment period. Matching principal and interest repayment and matching principal repayment are different concepts. Although the monthly repayment amount at the beginning of repayment may be lower than that in average capital, the interest paid in the end will be higher than that in average capital.
Matching principal and interest repayment method: the borrower repays the loan principal and interest in equal amount every month, and the monthly loan interest is calculated according to the remaining loan principal at the beginning of the month and settled every month. Because the monthly repayment amount is equal, in the initial monthly repayment of the loan, the principal of the loan is less after excluding the monthly settlement interest; In the monthly repayment after the end of the loan, after deducting the interest settled monthly, the principal of the loan is more. This repayment method actually takes up more bank loans and takes longer. At the same time, it is also convenient for borrowers to reasonably arrange their monthly life and financial management (such as renting a house, etc.). ), which is undoubtedly the best choice for people who are proficient in investment and good at "taking Qian Shengqian as their home". Suitable for people with stable family income, especially those with less temporary income and greater economic pressure. Because although the monthly repayment amount is the same, the ratio of principal to interest is different. Interest accounts for a large proportion in the initial repayment, while the proportion of loan principal is low, which is not suitable for those who intend to repay the loan in advance.
