I bought a commercial loan from Jiangjin Agricultural Bank, with the repayment of 365,438+65,438+2003. The principal and interest have been repaid. The bank calculated that we should repay 3407 yuan every month. How is this calculated? This is only the interest rate at this stage of this year. If the interest rate rises before 20111231,the new loan interest rate will be implemented from 20 12 1, and the new interest rate means that more money will be repaid every month. In other words, banks will only give a fixed value higher than the benchmark interest rate. Generally, the current mortgage is 10% off the benchmark interest rate (different from place to place). The interest rate of the People's Bank of China changed that year, and the new interest rate was implemented when the loan was made in June 65438+1 October1the following year. For example, in May this year, you signed a contract with the bank and bought a house with a loan. At that time, the interest rate was 6.8, and a 10% discount was 6. 12. Until the end of this year, the monthly repayment is certain. However, on July 7 this year, the benchmark loan interest rate became 7.05, with a 10% discount of 6.345, and the interest rate will not change again on February 3 this year.
