"Title 28 of the Code of Federal Regulations, part 505, allows for assessment of a fee to cover the average cost of incarceration for Federal inmates. We calculate the cost of incarceration fee (COIF) by dividing the number representing the Bureau of Prisons (Bureau) facilities’ monetary obligation (excluding activation costs) by the number of inmate-days incurred for the fiscal year, and then by multiplying the quotient by the number of days in the fiscal year. Based on FY 2018 data, FY 2018 COIF was $37,449.00 ($102.60 per day) for Federal inmates in Bureau facilities and $34,492.50 ($94.50 per day) for Federal inmates in Community Corrections Centers."
