Over 30 years of retirement, Mantel would collect as much as $4.59 million, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.
The projection assumes Mantel received $96,401 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Mantel will have already received $195,694 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
