Over 30 years of retirement, Henson would collect as much as $434,595, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Henson received $9,134 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Henson will have already received $28,232 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
