Over 30 years of retirement, Rosenberger would collect as much as $768,672, according to a projection by Local Government Information Services (LGIS), which publishes Sangamon Sun.
The projection assumes Rosenberger received $16,156 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Rosenberger will have already received $67,591 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
