Over 30 years of retirement, Butterfield would collect as much as $3.08 million, according to a projection by Local Government Information Services (LGIS), which publishes Kankakee Times.
The projection assumes Butterfield received $64,661 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Butterfield will have already received $199,861 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
