Answer:
The penalty will be $133.333 for the early withdrawal.
Explanation:
On a $20,000 earning 4% annually, the amount of interest earned per year is:
$ 20 , 000 x 4% = $ 800
On a monthly basis, the CD earns:
$ 800 / 12 = $ 66.667
If the penalty involves a two (2) months worth of interest, then, the penalty for the early withdrawal will be:
2 x $ 66.667 = $ 133.333
