Over 30 years of retirement, Montgomery would collect as much as $553,303, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Montgomery received $11,630 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Montgomery will have already received $35,947 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
