Yes, interest is not calculated for the extra money, but the interest is calculated from the day you take it out of 500 yuan, and you don't enjoy the interest-free repayment period, which is five ten thousandths per day, plus the withdrawal fee of 10-20 yuan, so you'd better call the customer service of its credit card center to check the exact repayment amount when you repay. If the deposit amount is insufficient, not only will there be a high late payment fee, but your personal credit record will also be affected.
