Calculated from the date of loan issuance. As a national professional financial institution, China Development Bank has been committed to promoting national economic development and personnel training. According to the regulations of China Development Bank, the interest of student-origin student loans is calculated from the date of loan issuance. This means that once the loan is issued, interest begins to accumulate. Therefore, students need to repay as soon as possible within the loan period to avoid the continuous accumulation of interest.
