First of all, if the credit card bill of 2,000 yuan exceeds the final payment date by three days, interest will accrue. The specific amount of interest generated depends on the following factors:

1. Interest rate: The interest rate of a credit card is an important factor in determining the amount of interest. Generally speaking, credit card interest rates range from 15% to 25%. Assume the interest rate is 20%.

2. Overdue days: The more days past the final payment date, the more interest will be accrued. Assume that it is three days past the final payment date.

3. Amount to be repaid: The 2,000 yuan shown on the bill is the amount that needs to be repaid. If there is partial repayment before the final repayment date, the amount to be repaid will be reduced, thus affecting the accrual of interest.

Based on the above assumptions, we can draw the following calculation results:

First, calculate the daily interest: 2,000 yuan × 20% ÷ 365 = 2.74 yuan/day.

Next, calculate the overdue interest: 2.74 yuan/day × 3 days = 8.22 yuan.

So, if the last payment date is exceeded by three days, interest of 8.22 yuan will be incurred.

To sum up, if the credit card bill of 2,000 yuan is three days past the last payment date, 8.22 yuan of interest will accrue. The calculation of interest depends on the credit card's interest rate, the number of days past due and the amount to be repaid.

Extended information: Please note that the above calculations are only examples and do not represent the actual situation of all credit cards. The interest rates and interest calculation methods of different banks and different credit card products may be different. In addition, late payments will not only accrue interest, but may also incur other fees, such as late fees or penalties. To avoid overdue fees, please try to repay on time.

The above are the answers and analysis to the questions. I hope they are helpful to you. If you have any other questions, please feel free to ask.
