Over 30 years of retirement, Johnson would collect as much as $408,939, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Johnson received $8,595 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Johnson will have already received $17,448 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
