Over 30 years of retirement, Henderson would collect as much as $2.21 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Henderson received $46,484 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Henderson will have already received $143,678 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
