Former state university employee Marlette Roebuck Knight, who retired in August 2016, saved $41,179 toward a pension over 17 years working for state universities, State Universities Retirement System of Illinois records show.

Over 30 years of retirement, Roebuck Knight would collect as much as $666,514, according to a projection by Local Government Information Services (LGIS), which publishes DuPage Policy Journal.

The projection assumes Roebuck Knight received $14,009 in the first year of retirement, then 3 percent annual increases thereafter, compounded.

After 3 years of retirement, Roebuck Knight will have already received $43,300 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
