Over 30 years of retirement, Derby would collect as much as $4.37 million, according to a projection by Local Government Information Services (LGIS), which publishes McLean County Times.
The projection assumes Derby received $91,955 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 2 years of retirement, Derby will have already received $186,669 in retirement benefits, or more than the sum total of the retiree's contributions to the teachers' pension fund.
