If the repayment is made according to the matching principal and interest, the interest rate is 5.44% and the loan amount is 600,000 yuan, the total interest is 6 18305.33 yuan, and the total repayment amount is 12 18305.33 yuan. The interest rate is 5.07% and the loan amount is 600,000 yuan, so the total interest is 568,792.97 yuan and the total repayment amount is1168,792.97 yuan. So the interest difference is 495 12.36 yuan.

The amount of interest depends on three factors: principal, deposit period and interest rate level. The calculation formula of interest is: interest = principal x interest rate x deposit period. Interest is the monetary reward obtained by lending (depositing) the principal. The essence of interest is a part of profit and a transformation form of surplus value. The yield of interest is directly proportional to the interest rate.
