An audit on the Iowa Department of Corrections shows it cost $263-million to run the state’s nine institutions in 2012.
The figure is an increase of about $1.5-million from 2011.
It all breaks down to an average of just over $83 per inmate per day.
The annual cost of an inmate ranges from $20,900 to $52,400 per year.
The North Central Correctional Facility in Rockwell City spends the least on inmates and the Iowa Medical and Classification Center in Oakdale spends the most.
