Can You Get Out of Prison Early for Good Behavior?

Yes, you can get out of prison early for good behavior, but the specifics decide everything. Federal inmates serving more than a year can earn up to 54 days off every year of their imposed sentence just by following the rules, and the First Step Act added a second credit system that moves eligible inmates into halfway houses or home confinement even sooner. State systems run on their own rules, and at least 38 states offer some form of credit. What you’re convicted of, what programs you complete, and whether you stay out of disciplinary trouble determine how much of that potential actually translates into days off.

The 54-Day Federal Good Conduct Rule

Under 18 U.S.C. § 3624, every federal inmate serving more than one year can earn up to 54 days of good conduct time for each year of the sentence the judge imposed.1Office of the Law Revision Counsel. 18 US Code 3624 – Release of a Prisoner The First Step Act of 2018 changed the calculation base from time actually served to the imposed sentence, which produces more credited days. On a 10-year sentence, maxing out every year works out to 540 days, roughly 18 months off the bench.2Federal Bureau of Prisons. First Step Act Overview

The credit is not automatic. The Bureau of Prisons must find that you displayed “exemplary compliance” with institutional rules during the period in question, and the BOP also considers whether you earned or made progress toward a GED or high school diploma.1Office of the Law Revision Counsel. 18 US Code 3624 – Release of a Prisoner Fall short and you get less, or none at all, for that year. Credit that was never earned cannot be awarded later.

First Step Act Earned Time Credits

Good conduct time is the baseline. On top of it, the First Step Act created a second credit for actively participating in programs the BOP recommends for you. For every 30 days of successful participation in recommended programming, you earn 10 days of time credits.3Office of the Law Revision Counsel. 18 USC 3632 – Development of Risk and Needs Assessment System If the BOP has classified you as minimum or low risk across your last two assessments, you earn 15 days per 30-day period instead.4eCFR. 28 CFR Part 523 Subpart E – First Step Act Time Credits

Qualifying programs include substance abuse treatment, cognitive behavioral therapy, educational courses, and vocational training. The important condition: the program must be one the BOP recommended for you based on its assessment, not just something available in your unit.2Federal Bureau of Prisons. First Step Act Overview

These credits work differently from good conduct time in a way worth understanding. They do not directly subtract days from your sentence. They qualify you for transfer to prerelease custody: a halfway house or home confinement.2Federal Bureau of Prisons. First Step Act Overview You leave the prison facility earlier, which is what most people mean by “early release,” but the distinction matters when you’re counting dates.

Who Cannot Earn First Step Act Credits

The statute lists dozens of offenses that disqualify an inmate from earning First Step Act credits. The categories are broader than most people assume:3Office of the Law Revision Counsel. 18 USC 3632 – Development of Risk and Needs Assessment System

  • Violent offenses, including homicide, assault with intent to murder, kidnapping, carjacking resulting in serious injury, robbery, and domestic assault by habitual offenders.
  • Terrorism and espionage offenses, including those involving weapons of mass destruction, biological or chemical weapons, or gathering defense information for a foreign government.
  • Sex offenses and human trafficking, including sexual abuse, sex trafficking, and sexual exploitation of children.
  • Firearms offenses, including using a firearm during a violent crime or drug trafficking offense, and being a repeat felon in possession of a firearm.
  • High-level drug trafficking convictions, particularly those carrying the highest statutory penalties.
  • Other serious crimes, including genocide, treason, destruction of aircraft, and threats against the President.

Inmates with these convictions can still earn good conduct time under § 3624(b), which does reduce actual time served. They just cannot earn the extra First Step Act credits that would move them to prerelease custody sooner.2Federal Bureau of Prisons. First Step Act Overview

State Good Time and the 85 Percent Ceiling

Most people in prison are in state facilities, and state good time systems vary dramatically. At least 38 states offer some form of good time or earned time credits. Earning rates range from a few days per month to day-for-day credit, where one day off is earned for every day served with good behavior. Some states tie the rate to custody classification or the severity of the offense, and many offer separate earned-time credits for completing educational, vocational, or treatment programs on top of basic good time.

The big limiter is truth-in-sentencing. These laws require inmates convicted of certain offenses, usually violent ones, to serve a set portion of their sentence before any release. The most common threshold is 85% of the imposed sentence, which more than two dozen states adopted, often as a condition of federal grant funding.5Bureau of Justice Statistics. Truth in Sentencing in State Prisons Under an 85% rule, someone sentenced to 20 years cannot get out before serving 17 years, no matter how clean their record is.

Halfway House or Home Confinement

In the federal system, “early release” through First Step Act credits usually means transfer to one of two settings. The first is a Residential Reentry Center, commonly called a halfway house, where you live in a community facility, hold a job or attend programming, and follow curfew and reporting rules. Under the Second Chance Act, halfway house placement can run up to 12 months, with the BOP setting the length based on recidivism risk and transitional service needs.6United States Courts. How Residential Reentry Centers Operate and When to Impose

The second is home confinement, generally for inmates who do not need the structure of a halfway house. A 2025 BOP directive expanded home confinement eligibility and stated there is no restriction on how many earned time credits may be applied toward home confinement.7Federal Bureau of Prisons. Federal Bureau of Prisons Issues Directive to Expand Home Confinement, Advance First Step Act An inmate with a large bank of credits could spend a significant portion of the tail end of their sentence at home.

To qualify using earned credits, you generally need minimum or low recidivism risk across your last two assessments. If your risk is higher, you can petition the warden, who may approve the transfer after finding you are not a danger to the community, have made a good-faith effort in programming, and are unlikely to reoffend.4eCFR. 28 CFR Part 523 Subpart E – First Step Act Time Credits

How Fast Infractions Wipe Out Credits

A single disciplinary incident can erase months of accumulated credits. The BOP ties mandatory losses to the severity of the prohibited act:8Federal Bureau of Prisons. Program Statement 5270.09 – Inmate Discipline Program

  • Greatest severity offenses: loss of at least 41 days, or 75% of available credit for the period if fewer than 54 days are available.
  • High severity offenses: loss of at least 27 days, or 50% of available credit.
  • Moderate severity offenses: loss of at least 14 days, or 25% of available credit, after two or more moderate acts in the same credit year.
  • Low severity offenses: loss of at least 7 days, or 12.5% of available credit, after three or more low-level acts in the same credit year.

Only the Discipline Hearing Officer can disallow good conduct time, and the decision factors in the severity of the act alongside agency guidelines.8Federal Bureau of Prisons. Program Statement 5270.09 – Inmate Discipline Program One serious incident, like possessing a weapon or assaulting staff, can cost more time than a full year of good behavior earned. The math is asymmetric: earning 54 days takes a year of exemplary conduct; one bad hearing can erase most of it in an afternoon.

Infractions also affect First Step Act earned time credits on a separate track. Behavioral violations can block credits from being applied toward prerelease custody even when you technically earned them through programming. The BOP tracks both systems independently.

Appealing a Disciplinary Finding

If you believe a disciplinary finding or sanction was wrong, the BOP’s Administrative Remedy Program has three levels:9eCFR. 28 CFR Part 542 – Administrative Remedy

  • Warden level: a formal written complaint filed at the institution. For Discipline Hearing Officer decisions, the first appeal goes directly to the Regional Director instead.
  • Regional Director: appeal within 20 calendar days of the prior response.
  • General Counsel: final appeal within 30 calendar days of the Regional Director’s response.

Each appeal must address the specific issues raised at the prior level, and new arguments cannot be introduced for the first time on appeal. Winning is difficult: the hearing officer’s findings carry significant weight and the review standard favors the institution. Clear documentation of what happened and any procedural errors during the hearing gives you the strongest chance.

Other Ways to Shorten a Federal Sentence

Good behavior credits are the main path, but federal law provides a few other mechanisms that are not strictly good-behavior provisions. An inmate’s rehabilitation record often matters anyway, because judges weigh it when deciding these motions.

Compassionate release under 18 U.S.C. § 3582(c)(1)(A) allows a court to reduce a sentence when extraordinary and compelling circumstances justify it. Common grounds include terminal illness, a serious medical condition the prison cannot adequately treat, or advanced age combined with significant time already served. An inmate can file directly with the court after either exhausting the BOP’s internal process or waiting 30 days from submitting a request to the warden, whichever comes first.10Office of the Law Revision Counsel. 18 USC 3582 – Imposition of a Sentence of Imprisonment Courts also consider whether the inmate poses a danger to the community, and a clean disciplinary record strengthens that argument.

Rule 35 of the Federal Rules of Criminal Procedure lets the government ask a court to reduce your sentence if you provided substantial help in investigating or prosecuting someone else. The motion generally must be filed within one year of sentencing, with exceptions for information not reasonably available earlier.11Legal Information Institute. Federal Rules of Criminal Procedure Rule 35 – Correcting or Reducing a Sentence Only the government can initiate it.

Retroactive guideline reductions are another route. When the U.S. Sentencing Commission lowers a sentencing range, inmates sentenced under the older, higher range may petition under 18 U.S.C. § 3582(c)(2) for a reduced sentence.10Office of the Law Revision Counsel. 18 USC 3582 – Imposition of a Sentence of Imprisonment These motions have become more common as federal drug sentencing guidelines have been revised downward in recent years.
