Over 35 years of retirement, Krantz would collect as much as $1.135 million, according to a projection by Local Government Information Services (LGIS), which publishes Kane County Reporter.
Krantz, 60, who currently lives in Newburgh, IN earned $30,160 in her final year at Aurora East USD 131.
The projection assumes Krantz will receive 58.3 percent of that total - $17,594 - in her first year of retirement, then 3 percent annual increases thereafter, compounded.
After three years of retirement, Krantz will have already received $54,382 in retirement benefits, or more than the sum total of her contributions to the state teachers' pension fund.
According to the Illinois State Board of Education (ISBE), 13.2 percent of Aurora East USD 131 students met or exceeded the standards for the "PARCC" exams. ISBE reported that 19.2 percent of district's graduates were deemed "college ready" last year.
