Assume that the total loan amount is 6,543.8+0,000, and each loan is reduced by 6,543.8+0,000. For 30 years, the interest rate was 6.2%. The following are possible calculation results:
1. 1. Calculation of monthly repayment amount: According to the total loan amount, loan term and interest rate, the monthly repayment amount can be calculated by using the matching principal and interest repayment formula. Suppose the calculation result is X.
2. Then, determine the new total amount after each loan reduction: the initial total amount of loans minus each loan reduction. For the first time, it decreased by 654.38+million, and the total amount of remaining loans was 900,000.
3. Next, calculate the monthly repayment amount under the new total amount: use the same formula to calculate the monthly repayment amount under the new total amount, assuming that the result is Y.
4. Calculate the amount of underpaid interest: subtract the interest difference under the new total from the initial total interest. The initial total interest can be obtained by multiplying the monthly repayment amount by the number of repayment months and subtracting the total initial loan amount. The interest difference is the new monthly repayment amount multiplied by the number of repayment months, and then the new total amount is subtracted.
Summary:
-For every short-term loan of RMB 654.38+10,000, the underpaid interest will decrease with time, because the repayment period has not changed.
This is because the new total amount will reduce the interest calculation base after each loan reduction, thus reducing the interest payment.
-The loan interest rate and repayment period also have an impact on the amount of interest ultimately underpaid, but these factors are no longer considered in the scenario given by the hypothesis.
Extended data:
-Loan interest rate: Loan interest rate refers to the loan interest fee charged by financial institutions to borrowers. The loan interest rate is usually determined according to the market interest rate, the borrower's credit status and other factors, and can affect the total cost of the loan.
-Loan term: The loan term refers to the repayment time agreed between the borrower and the financial institution. The longer the loan term means that the longer the repayment time, the lower the monthly repayment amount, but the total interest expense will increase.
-Matching principal and interest repayment: Matching principal and interest repayment is a common repayment method, and the monthly repayment amount remains unchanged, but the interest paid at the initial stage is more, and gradually decreases at the later stage.
