detailed description:
1. annual interest rate: different credit cards may have different annual interest rates. Suppose the annual interest rate is 2%.
2. Calculation formula: Credit card companies usually calculate interest on a daily basis. Suppose the credit card company calculates a year according to 36 days, then the daily interest is equal to the amount owed multiplied by the annual interest rate divided by 36. Therefore, for 5 yuan's arrears, the daily interest is: 5 * .2/36 = .2778 yuan.
Summary:
If the credit card is owed to 5 yuan and the repayment is delayed by one day, according to our hypothetical conditions, the interest amount is .2778 yuan.
