Over 30 years of retirement, Birkey would collect as much as $2.34 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Birkey received $49,256 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Birkey will have already received $99,990 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
