Over 30 years of retirement, Grigsby would collect as much as $527,915, according to a projection by Local Government Information Services (LGIS), which publishes Carbondale Reporter.
The projection assumes Grigsby received $11,096 in the first year of retirement, then 3 percent annual increases thereafter, compounded.
After 3 years of retirement, Grigsby will have already received $34,297 in retirement benefits, or more than the sum total of the retiree's contributions to the state pension fund.
