Over 30 years of retirement, Cheng would collect as much as $13,113, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Cheng received $275 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Cheng will have already received $1,149 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
