All of the previous years of SS taxed earnings get multiplied by an index factor. Then you take the highest 35 and calculate the Average Indexed Monthly earnings.
Do not forget that any years that have less than the 'Substantial' earnings (WEP) limit do not count at all from what I have read. That is something I just learned.
So, in my situation, the year I worked while in high school, and the year I worked for mainly cash while in college doesn't count... I still have 38 other years to choose from.
