If you overdraw your credit card, the withdrawal amount is 50% of your credit card limit, and each card can only withdraw up to 5000 per day. There is a handling fee and interest for overdraft withdrawal. The handling fee is 0.5% of the cash withdrawal amount, with the lowest in 2 yuan and the highest in 50 yuan. There is no interest-free period for cash withdrawal, and the bank will charge interest at the rate of 5/10000 per day from the date of withdrawal.

The handling fee for 1500 is 1500*0.5%=7.5, and the daily interest is 1500*0.0005=0.75. Because cash withdrawal does not enjoy interest-free period, one day counts as one day's interest, so try to repay as soon as possible.
