This calculation is based on the assumption that the annual interest rate is 3.5%. The monthly repayment amount of the loan can be calculated by the equal principal and interest repayment method. Equal principal and interest repayment method, that is, equal principal and interest are repaid every month until the loan expires. In this case, the total loan is 2 million yuan, which is paid off in 30 years (that is, 360 months) at the annual interest rate of 3.5%, and the monthly repayment amount is about 8980.89 yuan.
