There are two repayment methods for commercial loans, one is average capital, and the other is equal principal and interest. If the repayment method is average capital, after 10 years, the residual interest is about 3/5 of the total interest. If equal principal and interest repayment is adopted, the remaining interest is 2/5 of the total interest. Based on the previous mortgage in Bian Xiao, the loan is RMB 6,543,800+7,000, with the interest rate of 7.5% for the loan period of 20 years and the total interest of about RMB 6,543,800+6,000. After the repayment of 654.38+00 years, the residual interest is still about 80,000 yuan.

1. Equal principal and interest loan method.

Matching principal and interest repayment means adding up the total principal and interest, and then sharing it evenly every month. The monthly repayment amount is fixed, but the proportion of principal increases month by month and the proportion of interest decreases month by month. Monthly repayment amount = loan principal × [monthly interest rate× (1+monthly interest rate) repayment months ]{[( 1+ monthly interest rate) repayment months ]- 1}. This repayment method actually takes up more bank loans and takes longer. At the same time, it is also convenient for borrowers to arrange their monthly life reasonably. It is suitable for families with relatively stable incomes, and economic conditions do not allow them to make relatively large investments in advance, such as civil servants, teachers and other groups with stable incomes and stable jobs.

Second, the loan method in average capital.

Average capital divides the total loan into equal parts during the repayment period, and repays the same amount of principal and the interest generated by the remaining loans in that month every month. The monthly repayment of principal is fixed, but the interest is getting less and less, so the total amount of principal and interest is getting lower and lower. This repayment method has great pressure in the early stage and is suitable for people at the peak of work. The calculation formula is: monthly repayment amount = (loan principal/repayment months)+(principal-accumulated amount of repaid principal) × monthly interest rate.

Third, the comparison between the two.

Take the loan of 3 million yuan as an example, with an annual interest rate of 4.86% and a loan term of 30 years. Matching principal and interest repayment, with total interest of 27056 18.40 yuan; Repay the principal with equal amount, and the total interest is 265,438+093,075.00 yuan. The more loans, the longer the service life, and the repayment of equal principal and interest is more than the repayment of equal principal.
