Over 30 years of retirement, McMahon would collect as much as $914,538, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes McMahon received $19,222 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, McMahon will have already received $59,414 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
