Description:

1. First, we need to calculate the monthly interest rate of the loan. The annual interest rate is 4%, which is 0.04, so the monthly interest rate is 0.04/ 12=0.00333.

2. Calculate the number of repayment periods. The total loan amount is 654.38+0.5 million, and the repayment period is 654.38+00 years, that is, 654.38+0.20 months.

3. Use the loan formula to calculate the monthly repayment amount. The formula is: monthly repayment amount = (loan principal× monthly interest rate) /( 1-( 1+ monthly interest rate) (-number of repayment periods). Substituting numerical calculation, the monthly repayment amount is 6672 yuan.
