Former principal Raynell Walls, who retired in November 2016, saved $150,834 toward a pension over 37 years working for public schools, Chicago Teachers' Pension Fund records show.

Over 30 years of retirement, Walls would collect as much as $3.9 million, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.

The projection assumes Walls received $82,049 in the first year of retirement, then 3 percent annual increases thereafter, compounded.

After 2 years of retirement, Walls will have already received $166,559 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
