China Merchants Bank stipulates that the interest-bearing days are from the bookkeeping date of each account to the repayment date of the account, and the daily interest rate is five ten thousandths.

At present, China Merchants Bank provides a three-day grace period for repayment, and repayment within the grace period is regarded as timely repayment. If the repayment exceeds the grace period or the repayment amount is lower than the minimum repayment amount stipulated by the bank, the interest will be calculated from the bookkeeping date, and a late fee of 5% of the minimum repayment amount will be charged monthly.
