Over 30 years of retirement, Plankenhorn would collect as much as $577,595, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.
The projection assumes Plankenhorn received $12,140 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 1 years of retirement, Plankenhorn will have already received $12,140 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
