Former substitute teacher Thomas Glaser, who retired in March 2016, saved $33,150 toward a pension over 13 years working for public schools, Chicago Teachers' Pension Fund records show.

Over 30 years of retirement, Glaser would collect as much as $517,067, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.

The projection assumes Glaser received $10,868 in the first year of retirement, then 3 percent annual increases thereafter, compounded.

After 3 years of retirement, Glaser will have already received $33,592 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
