First of all, you need to know your billing date and interest-free repayment period. The repayment period is different according to different banks. You should first search for the repayment period of your credit card. You will be informed on the day of consumption overdraft. The repayment period will start on the bill date of this month or next month. After the repayment period, interest will be charged at 0.05% per day. For 2,000 yuan, the interest will be 1 yuan per day, which is 28-31 per month. Yuan does not vary. My personal suggestion is to pay it back as soon as you can, and use your credit card to spend in a reasonable and planned way.
