Over 30 years of retirement, Thornton would collect as much as $427,596, according to a projection by Local Government Information Services (LGIS), which publishes North Cook News.
The projection assumes Thornton received $8,987 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Thornton will have already received $37,600 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
