the calculation of credit card withdrawal interest varies with different banks and types of credit cards, but generally speaking, the credit card withdrawal interest is calculated according to the daily interest rate, and the interest is compounded monthly. The specific calculation formula is:

interest = cash withdrawal amount × daily interest rate× cash withdrawal days

, in which the daily interest rate is usually around .5%, but the specific interest rate may be different for banks and card types.

Take a bank's credit card as an example. Suppose the daily interest rate is .5%, and the withdrawal time is 3 days in 1 yuan:

Interest =1 yuan ×.5%×3 days =15 yuan

It should be noted that in addition to interest, a certain handling fee is usually charged for credit card withdrawal. The proportion of handling fees varies with banks and card types, generally between 1% and 3% of the cash withdrawal amount. At the same time, advance cash usually has no interest-free period, and interest is calculated from the date of withdrawal.

Therefore, when using credit card to withdraw cash, we should not only pay attention to the calculation of interest, but also consider the handling fee and other related expenses. If necessary, you can consult the credit card issuing bank to understand the specific cash withdrawal interest and handling fee policies.
