First of all, there are two concepts, namely principal and interest. There are two repayment methods for mortgages, one is equal amounts of principal and the other is equal amounts of principal and interest, which means the same principal is repaid every month. , the principal gradually decreases, then the interest will also decrease every month. Equal principal and interest means that the monthly repayment amount includes principal and interest, and it will be the same every month until the end of the repayment.

For example, if you borrow 120,000 yuan for two years, then your monthly principal repayment is 12/24. According to the equal amount of principal, you have to repay 5,000 principal every month. As for the interest, it depends on your Calculate the specific loan interest situation. For example, if the monthly interest is 4/1000, then the first month’s interest will be 120000*4/1000 = 480 yuan. The total repayment amount in the first month is 5480 yuan. The second month's interest is 115,000*four thousandths=460 yuan, and the total repayment in the second month is 54,600 yuan.
