Former substitute teacher Rosemary Regan, who retired in March 2018, saved $18,078 toward a pension over 9 years working for public schools, Chicago Teachers' Pension Fund records show.

Over 30 years of retirement, Regan would collect as much as $430,933, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.

The projection assumes Regan received $9,057 in the first year of retirement, then 3 percent annual increases thereafter, compounded.

After 2 years of retirement, Regan will have already received $18,386 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
