Different banks have different interest rates. Such as car loans, some banks implement the benchmark interest rate, and some banks float 10%-20%. Generally speaking, the loan interest rate of state-owned commercial banks is lower than that of local credit cooperatives and may be lower than that of regional commercial banks. At the same time, whether the loan needs to pay the handling fee and whether the collateral needs to be evaluated may lead to an increase in costs. Therefore, the price of bank credit products can not be determined only by the loan interest rate, but by combining various monetary expenditure factors, loan term and loan amount.

There are many ways of repayment, monthly average repayment and monthly average principal repayment. The monetary cost of these two ways is very different. The former has a high monetary cost, but the early repayment pressure is small; The latter's monetary cost is small, but the early repayment pressure is great. In addition, most banks allow borrowers to make a one-time "large repayment" during the loan period. If they have spare money, but it is not enough to pay off the loan in full, they might as well pay off part of it first, so as to reduce the total amount of the loan, thus reducing the interest expense.
