2. What is the principal and interest of a bank loan?

Loan principal and interest usually refers to the sum of the amount obtained by the lender and the amount repaid by the lender in the process of bank loan or provident fund loan; The loan principal generally refers to the amount of money borrowed by the borrower from the lender. The loan principal does not include any expenses that need to be spent in the process of borrowing, such as insurance premium and evaluation fee. These expenses, like the interest you need to pay, belong to the loan cost. The repayment methods are as follows: there are two repayment methods for the loan principal, one-time repayment and installment repayment. One-time repayment is to return all the principal and interest to the lender at the end of the loan cycle. There will be multiple repayments in installment repayment, and the principal and interest of repayment will be allocated to each installment repayment. Loans usually refer to bank loans or provident fund loans; "Principal" refers to the principal, that is, the amount obtained by the lender; "Interest" refers to interest, that is, the amount paid by the lender. Matching (principal and interest) repayment method means that the borrower repays the loan principal and interest in equal amount every month during the loan period (that is, the monthly repayment amount is the same). The calculation formula is as follows: monthly interest payment = residual principal multiplied by monthly loan interest rate; Monthly repayment of principal = monthly repayment of principal and interest minus monthly payment of interest. The average capital repayment method means that during the loan period, the principal returned in the monthly payment remains unchanged, the interest decreases every month, and the monthly payment decreases every month. The calculation method of monthly payment can refer to the following: 1, monthly principal payable (constant) = total loan divided by total repayment months; 2. Monthly interest payable (decreasing) = residual principal multiplied by monthly interest rate; 3. Monthly repayment amount (decreasing) = monthly principal plus monthly interest. If the repayment method of "equal capital" is adopted, compared with the matching principal and interest, the repayment pressure in the early stage of this repayment method will be greater, and the total repayment interest will be reduced compared with the matching principal and interest. The average capital repayment method keeps the principal unchanged in each repayment amount during the whole repayment period, and the repayment interest decreases month by month; The total principal and interest decreases month by month. This repayment method has great pressure on early repayment and is suitable for people with higher income or who want to repay in advance.

4. What is the principal-interest ratio of equal principal and interest?

There is no fixed proportion, and the equal principal and interest is the repayment method with the same monthly repayment amount. Because this algorithm adds up the total principal and interest of the loan and distributes it evenly to each month, the proportion of principal is small and the proportion of interest is large in the repayment amount matching the principal and interest in the early stage. When the repayment period is over half, it will become a large proportion of costs and a small proportion of interest. Basically, by the middle term, most of the interest has been paid off.
