Withdrawal of cash by China Merchants Bank credit card will incur handling fees and interest. The specific calculation is as follows:

1. Cash withdrawal handling fee: Domestic RMB cash advance is calculated as 100% of the amount of each cash advance. 1. The minimum handling fee is RMB 10 per transaction.

To withdraw 500 in cash, the handling fee is 500*1=5 yuan. Since the minimum charge is 10 yuan per transaction, the handling fee for withdrawing 500 in cash is also 10 yuan.

2. Cash withdrawal interest: Cash advance transactions do not enjoy interest-free repayment treatment. Interest will be charged at a daily interest rate of 0.5% from the transaction date until the settlement date.

Withdraw 500, the daily interest is 500*0.5=0.25 yuan
