The U.S. abolished parole many years ago. There is no parole system in the federal jurisdictions. Any sentence to serve in a federal prison is time to serve at approx. 85% prior to being released. Many federal criminal cases require a period of Supervised Release (similar to probation/parole) for a period of time after release from the pen.
States have laws that govern their states parole. In KY, if sent to the state prison sentences are served at 15%, 20%, 50% or 85% on the number of years imposed at sentencing depending on the crime convicted. Upon making state parole, the inmate is placed on state parole for the balance of the sentence originally imposed.
