The withdrawal amount is 50% of the credit limit of the credit card. This is 15 thousand, and there will be a withdrawal fee when you withdraw cash. The withdrawal fee of GDB credit card is 1.5%, which means that this fee reflects synchronous deduction, which means that you can only claim 98.5% withdrawal right. 15000 * 98.5% =14775, but the principal base is calculated according to15000 yuan.

To withdraw this part of the money, you need to charge five ten thousandths of the daily interest in full, 15000*0.0005=7.5 yuan.

If the billing period is full, it will be 25 days, 7.5*25= 187.5 yuan. Of course, if it is not full, the date of your withdrawal will be less than 25 days.

The daily interest for the next billing cycle is15000+187.5 =15187.5 * 0.0005 = 7.6 yuan.

There is no grace period because it does not reflect consumption. In any case, repayment requires full interest on each installment. Of course, the minimum monthly amount can be used, but it will not reduce the principal base of interest, which will be even worse. The minimum monthly repayment is 15 19 yuan in the first month and 1542 yuan in the second month, and so on, and more and more.
