Over 30 years of retirement, Grantham would collect as much as $72,504, according to a projection by Local Government Information Services (LGIS), which publishes Chicago City Wire.
The projection assumes Grantham received $1,524 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 4 years of retirement, Grantham will have already received $6,377 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
