2. Total interest: 2 15040.76 yuan.
3. Monthly payment: 202 1 yuan.
4. Repayment of principal and interest in the first month: loan principal * monthly loan interest rate (annual interest rate/12), that is, 27 * 6.55%/12 =1473.75.
The down payment of principal = monthly payment-interest paid in the first month = = 2021-1473.75 = 547.25 yuan.
5. Current interest = loan principal balance in the previous period * monthly loan interest rate (annual interest rate/12).
Outstanding loan principal at the end of the first period (balance at the beginning of the second period): 270,000-547.25.
Second interest: (270,000-547.25) * monthly loan interest rate (annual interest rate/12)= 1470.76 yuan.
Repayment of principal in the second phase = monthly payment-1470.76 = 550.24 yuan.
