The interest calculation method for credit cards is relatively simple, but it varies depending on the repayment situation and usage scenarios. First of all, if the cardholder can repay the card in full and on time, there will be no interest and only the amount consumed will be repaid. However, if you make an overdraft withdrawal, the interest will be calculated based on the daily interest rate of 5/10,000 and will accumulate from the day of withdrawal. A handling fee of 0.5 per transaction will also be charged (minimum 2 yuan per transaction).

In the case of overdue repayment or insufficient repayment, the calculation of interest will start from the date when the consumption is recorded, and the interest of 0.05% per day will be compounded monthly, which means that the unpaid interest will be Continue to accumulate interest. In addition, late repayment will also incur additional fees such as late payment fees. Therefore, when using a credit card, be sure to pay attention to the relevant fee regulations to avoid unnecessary additional expenses.

Late repayment on a credit card will incur penalty interest, which is usually five ten thousandths of the overdue amount. For example, if you spend 10,000 yuan one day overdue, the penalty interest is 5 yuan. Cash withdrawals will also generate interest, and the handling fees vary from bank to bank. Usually the interest is 50,000% of the cash withdrawal amount, and the daily interest for a cash withdrawal of 10,000 yuan is 5 yuan. Finally, if you choose to repay by credit card in installments, although you can repay in installments, you will incur handling fees. The handling rates vary depending on the number of installments, which is part of the bank's credit card business income.

In general, using your credit card wisely and making sure you pay it back on time are the keys to avoiding interest and additional fees. At the same time, understanding the details of credit card charges will help you better manage your personal finances.
