Over 30 years of retirement, Roberson would collect as much as $583,990, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.
The projection assumes Roberson received $12,275 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Roberson will have already received $51,353 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
