Generally, the temporary limit increase should be for three months. During these three months, your increased limit and your original credit card limit are counted as the limit of one credit card.
For example: If your original credit card limit is 10,000, and then you apply to increase the temporary limit, and after the application is approved, your temporary limit of 10,000 is added for 3 months (generally, the temporary limit of banks is 3 month is the deadline).
In this case, your current credit card status will be the normal limit of 20,000. During this period, if you consume all the 20,000 limit every month, the bill will still be calculated based on the normal 10% repayment amount, which is about 2,000.
However, by the third month, if you still use up your 20,000 limit, then after your temporary limit is reduced in the third month, the credit card limit will still be 10,000, and the other 10,000 will be The loan limit you have overdrawn.
