1, repayment on schedule, equal principal and interest.
Under the repayment method of matching principal and interest, a fixed repayment principal and interest is charged every month, and the specific interest calculation formula is:
Monthly repayment principal and interest = [loan principal× monthly interest rate× (1+monthly interest rate )× repayment months ]⊙[( 1+ monthly interest rate )× repayment months-1], where ""stands for power and "2 3" = 2× 2.
Monthly loan interest = (loan principal-repaid principal) × monthly loan interest rate.
Total loan interest = monthly repayment principal and interest × loan term-loan principal.
If the loan principal is 654.38 million yuan, assuming the loan interest rate is 7.2% and the loan term is one year, the monthly repayment of principal and interest will be 866 1.9 yuan, and the interest will be paid in 600 yuan in the first month, 55 1.63 yuan in the second month, 502.97 yuan in the third month and 45400 in the fourth month.
2. Regular repayment and average capital
Under the repayment method of equal principal, the fixed principal is charged every month, and the repayment interest decreases month by month. The specific interest calculation formula is as follows:
Monthly repayment principal and interest = monthly repayment principal+monthly repayment interest = (loan principal ÷ repayment months)+(principal-accumulated amount of repaid principal) × monthly interest rate, and monthly interest rate = annual interest rate ÷ 12.
The loan principal is 6,543,800 yuan, and the interest rate is 7.2%. Under the condition of one-year term, the monthly repayment principal is 8,333.33 yuan, of which the repayment interest decreases month by month by 50 yuan, the first month by 600 yuan, the second month by 550 yuan, and the third month by 500 yuan, and so on, and the total loan interest is 3,900 yuan.
3. Interest is calculated on a daily basis, and it will be repaid if borrowed.
Under the daily interest calculation method, the interest is calculated according to the actual borrowing days, and the specific calculation formula is as follows:
Daily interest = remaining unpaid principal × daily interest rate, and daily interest rate = annual interest rate ÷360.
Monthly loan interest = daily interest × current days.
Suppose the loan principal is 654.38+10,000 yuan, and the daily interest rate is 0.035%. If the principal is not repaid, the daily interest rate is 35 yuan, and if the month is 30 days, the monthly interest rate is 1.050 yuan. If the principal of 5000 yuan is repaid in the first installment, the daily interest of the second installment is = (100000-5000) × 0.035% = 33.25 yuan, and the monthly interest is 1030.75 yuan in the case of 3 1 day in the current month.
