Over 30 years of retirement, Butler would collect as much as $518,912, according to a projection by Local Government Information Services (LGIS), which publishes West Cook News.
The projection assumes Butler received $10,907 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Butler will have already received $45,630 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
