Bank loans are generally repaid on the 20th (or 10) of the next month after the loan is issued, and the repayment interest is calculated according to the actual number of days. If the loan is issued before 20th (or 10), the interest period of the first repayment will exceed 30 days, and the repayment in the first month will be particularly large. If the loan is issued after 20th (or 10).
