Matching principal and interest refers to a repayment method. Matching principal and interest means paying the same amount of loans (including principal and interest) every month during the repayment period. This is a concept different from average capital. Although the monthly repayment amount may be lower than the average capital repayment method at first, the interest paid in the end will be higher than the average capital repayment method commonly used by banks.

Average capital refers to a repayment method of loans. During the repayment period, the total amount of loans is divided into equal parts, and the same amount of principal and interest generated by the remaining loans of the month are repaid every month. In this way, because the monthly repayment amount is fixed and the interest is less and less, the borrower is under great pressure to repay at first, but as time goes on, the monthly repayment amount is less and less.

The characteristics of average capital: the monthly repayment amount is different, showing a state of decreasing month by month; It divides the loan principal equally according to the total repayment months, plus the interest of the remaining principal in the previous period, thus forming the monthly repayment amount. So the repayment amount in the average capital is more than one month, and then decreases month by month, less and less.

The average capital loan uses a simple interest rate method to calculate interest. At the settlement time of each repayment, only the remaining principal (loan balance) is calculated, that is to say, the outstanding loan interest is not calculated together with the outstanding loan balance, only the principal is calculated.

The characteristics of equal principal and interest: the monthly repayment amount is the same, which is essentially that the proportion of principal increases month by month, the proportion of interest decreases month by month, and the number of monthly repayments remains unchanged, that is, in the distribution proportion of "principal and interest" of monthly payment, the proportion of interest repaid in the first half is large, the proportion of principal is small, and it gradually turns into a small proportion of principal and interest after the repayment period is over half.

The loan with equal principal and interest is calculated according to compound interest. At the settlement time of each repayment, the interest generated by the remaining principal will be calculated together with the remaining principal (loan balance), that is to say, the outstanding interest will also be calculated, which seems to be more severe than "rolling interest". In foreign countries, it is recognized as a loan method suitable for the interests of lenders.
