Over 30 years of retirement, Mattie would collect as much as $992,940, according to a projection by Local Government Information Services (LGIS), which publishes Rock Island Today.
The projection assumes Mattie received $20,870 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Mattie will have already received $87,312 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
