Over 30 years of retirement, Yerkes would collect as much as $140,736, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Yerkes received $2,958 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Yerkes will have already received $12,375 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
