Equal principal repayment means that the lender allocates the principal to each month and at the same time pays off the interest between the previous transaction day and this repayment date. Compared with equal principal and interest, this repayment method has a lower total interest expense, but more principal and interest are paid in the early stage, and the repayment burden decreases month by month. The equal principal repayment method is a repayment method that is very simple to calculate and highly practical. The basic algorithm principle is to repay the loan principal in equal installments during the repayment period, and at the same time repay the interest generated by the unpaid principal in the current period. The method can be monthly repayment and quarterly repayment. Due to the requirements of bank interest settlement practices, quarterly repayment is generally adopted (such as Bank of China). The equal principal repayment method is not an option to save interest. If there is a real way to save interest, it is to learn to consume wisely. According to your own financial strength, you should tailor your loan, live within your means, borrow as little as possible, and take short loans. This is the only feasible way. The equal principal repayment method refers to a loan repayment method, which is to divide the total loan amount into equal parts during the repayment period, and repay the same amount of principal and the interest generated by the remaining loan in that month every month. In this way, due to The monthly principal repayment is fixed, and the interest is getting smaller and smaller. The borrower has greater repayment pressure at first, but as time goes by, the monthly repayment becomes smaller and smaller. It also makes it easier to determine your loan repayment ability based on your income. The total expenditure of this repayment model may be reduced compared to the equal principal and interest, but the repayment pressure is greater at the beginning.
