Over 30 years of retirement, Dunn would collect as much as $426,355, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Dunn received $8,961 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Dunn will have already received $18,191 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
