Over 30 years of retirement, Tierney would collect as much as $2.97 million, according to a projection by Local Government Information Services (LGIS), which publishes North Cook News.
The projection assumes Tierney received $62,425 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Tierney will have already received $192,950 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
