Suppose there is an overdraft of 5, yuan in the credit card, and the billing date is the 9th of each month. If only 4,999 yuan is paid back by the repayment date, how can the interest be calculated? thank you there are two calculation methods!

At present, most banks use the method of full interest calculation. If there is no full repayment, you should calculate your interest from the day you spend to the day you repay. You should also calculate the interest on the 4999 you have paid back, and the remaining 1 yuan should also be calculated until the day you have paid back this 1 yuan.

The other way is the differential interest method. If you don't pay back in full on the day of the final repayment, the bank will only charge the interest on the part you haven't paid back. According to your hypothetical situation, it will only charge the interest on the unpaid 1 yuan from the day of consumption to the day you have paid back this 1 yuan money!

At present, 99% of banks use full interest. As far as I know, only ICBC uses differential interest!
