How is the postal credit card overdraft interest calculated? To be more detailed, I overdrafted 4,399 yuan on December 1st and I have to pay it back today, but I don’t have enough money. How much interest will I pay tomorrow?

If you swipe your card and repay in full before the repayment date, there will be no interest.

If you fail to repay the loan in full, the interest rate for 4,399 yuan per day is 2.19 yuan. Collection starts on December 2nd.
