The credit card of CCB has a fixed amount and a withdrawal amount, and the withdrawal amount is configured according to 50% of the credit card amount. The bank stipulates that the daily withdrawal of each card should not exceed 2000 yuan. To sum up, the credit card with a credit line of 24,000 yuan is12,000 yuan (including the withdrawal principal and withdrawal fee, which is 0.5% of the withdrawal amount, with a minimum of 2 yuan). Therefore, you can withdraw at most 1 1900 (a total withdrawal fee of 59.5 yuan is generated, and the remaining withdrawal amount =12000-11900-59.5 = 31.5 yuan.

At the same time, overdraft withdrawal does not enjoy interest-free period, and interest of five ten thousandths of the cash amount is charged every day from the date of withdrawal.

For example, the landlord overdraws 2000 yuan and pays it back after 10 days.

Total amount payable = withdrawal principal+withdrawal handling fee+withdrawal interest.

= 2000+2000 * 0.5%+2000 * 0.05% *10 (10 interest)

=2000+ 10+ 10

=2020 yuan
