Former teacher and speech pathologist Marilyn Sandler, who retired in August 2017, saved $176,787 toward a pension over 34 years working for public schools, Chicago Teachers' Pension Fund records show.

Over 30 years of retirement, Sandler would collect as much as $3.52 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.

The projection assumes Sandler received $74,001 in the first year of retirement, then 3 percent annual increases thereafter, compounded.

After 3 years of retirement, Sandler will have already received $228,730 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
