The interest rate for credit cards is generally 0.5% daily interest rate, which is equivalent to an annual interest rate of 18.25%, calculated on a monthly compound interest basis. This interest rate is calculated based on the number of installments and the processing fee of the credit card.

There is no interest for credit card repayment in full and on time, but if you choose to repay in installments or withdraw cash overdraft, you will need to pay certain interest and handling fees. For installment repayment, the interest is calculated based on the number of installments and the handling rate. The installment handling rates of different banks are different, generally between 0.5% and 1%. For overdraft withdrawals, in addition to paying handling fees, interest also needs to be calculated from the day of withdrawal. The daily interest rate is 0.05% and is calculated on a monthly compound interest basis. When using a credit card, it is recommended to repay in full and on time to avoid unnecessary interest and fees.
