Over 30 years of retirement, Johnson would collect as much as $3.42 million, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Johnson received $71,791 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Johnson will have already received $145,736 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
