Loans to buy a car are generally based on the total amount of the first loan and calculated according to the bank loan interest rate when signing the contract. If the bank interest rate changes during the repayment period, it will be adjusted with the interest rate and remain unchanged for one year. Car dealers generally use the method of equal monthly repayment of principal and interest. Taking the automobile consumption loan of a bank as an example, the repayment formula is as follows:

Repayment amount per installment = loan principal/number of repayment installments+(principal-accumulated repayment principal) × interest rate (monthly interest rate)

For example, someone bought a car with 6.5438+0.5 million yuan, and the loan was 6.5438+0.5 million yuan for three years. The loan interest rate was 9.5 points for three years (the monthly interest rate was 0.26 points).

therefore

The repayment amount in the first month =100000/36+(100000-0) * 0.26% = 3037 (approximate value).

Repayment in the second month =10000/36+(100000-2777) * 0.26% = 3029 (approximate value. )
