Over 30 years of retirement, Mangun would collect as much as $455,437, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Mangun received $9,572 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Mangun will have already received $19,431 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
