Do federal inmates serve 85 percent of time plus goodtime?

Federal inmates generally must serve at least 85% of their sentence before becoming eligible for parole or supervised release, as mandated by the Violent Crime Control and Law Enforcement Act of 1994. However, they can earn "good time" credits, which can reduce their time served by up to 54 days per year for good behavior. This means that while they serve a significant portion of their sentence, good time can allow for earlier release under certain conditions.
