Over 30 years of retirement, Butterfield would collect as much as $559,589, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Butterfield received $11,762 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Butterfield will have already received $36,355 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
