Over 30 years of retirement, Armstrong would collect as much as $3.33 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Armstrong received $70,065 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Armstrong will have already received $142,232 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
