Over 30 years of retirement, Koehler would collect as much as $2.14 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Koehler received $44,919 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Koehler will have already received $138,841 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
