Over 30 years of retirement, Armstrong would collect as much as $449,696, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Armstrong received $9,452 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 5 years of retirement, Armstrong will have already received $50,184 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
