Over 30 years of retirement, Koehler would collect as much as $4.31 million, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.
The projection assumes Koehler received $90,624 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Koehler will have already received $280,110 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
