Over 30 years of retirement, Johnston would collect as much as $599,610, according to a projection by Local Government Information Services (LGIS), which publishes Kane County Reporter.
The projection assumes Johnston received $12,603 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 1 years of retirement, Johnston will have already received $12,603 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
