Will I serve my whole sentence in a federal case?

Parole has been abolished in the federal system. If you are sentenced to prison, you are eligible for 54 days of good time credits for sentences of more than one year. Therefore, you will usually serve about 85 percent of your sentence. If you can demonstrate an alcohol or drug problem, it is also possible to have your sentence reduced by up to a year by participating in a drug program called RDAP.
