The penalty for armed robbery is severe in every U.S. jurisdiction. State sentences generally run from five years to life, federal sentences reach up to 20 years under the Hobbs Act and 25 years for armed bank robbery, and a separate federal firearm charge can stack at least 5 to 30 or more years of mandatory consecutive prison time on top. Fines can reach six figures, restitution is often required, and the collateral consequences — lost firearm rights, deportation for non-citizens, licensing barriers — last long after release.
State Prison Sentences
Most armed robbery prosecutions happen in state court. Every state classifies the offense among its highest felony categories, though the labels differ: first-degree felony, Class 1, Class 2, Class X. The label matters less than the range it carries.
Sentencing ranges generally fall somewhere between five years and life imprisonment. A first-time offender with no criminal history and no injured victim tends to land near the lower end. Prior convictions or aggravating facts can push a sentence to several decades or life. Fines sometimes reach six figures depending on the jurisdiction.
Many states impose mandatory minimums for armed robbery, which means the judge cannot sentence below a set floor regardless of how sympathetic the facts look. If a state has a habitual-offender statute, a third serious felony conviction can carry 25 years to life on its own.
Federal Prison Sentences
A robbery becomes federal when it touches a federal interest. The usual route is the Hobbs Act, which covers any robbery affecting interstate commerce. That threshold is lower than it sounds; robbing a convenience store that sells goods shipped from out of state can qualify. A Hobbs Act conviction carries up to 20 years in federal prison.1Office of the Law Revision Counsel. 18 USC 1951 – Interference With Commerce by Threats or Violence
Robbing a federally insured bank falls under a separate statute. If a dangerous weapon is used or anyone’s life is put in jeopardy, the maximum rises to 25 years.2Office of the Law Revision Counsel. 18 USC 2113 – Bank Robbery and Incidental Crimes Federal carjacking carries up to 15 years, up to 25 years if the victim suffers serious bodily injury, and up to life or the death penalty if someone is killed during the offense.3Office of the Law Revision Counsel. 18 USC 2119 – Motor Vehicles
Firearm Enhancements Under § 924(c)
Federal penalties get much more severe when a gun is involved. Under 18 U.S.C. § 924(c), using a firearm in a federal violent crime is charged separately, and the sentence stacks on top of the underlying robbery sentence. The mandatory additions:
- Possessing or carrying a firearm: at least 5 additional years
- Brandishing a firearm: at least 7 additional years
- Discharging a firearm: at least 10 additional years
- Using a short-barreled rifle or shotgun: at least 10 additional years
- Using a machine gun, destructive device, or silencer: at least 30 additional years
Two features make these numbers hit hard. The § 924(c) time runs consecutively; no judge can order it served at the same time as the robbery sentence. And a second § 924(c) conviction carries a 25-year minimum, rising to life if the second offense involves a machine gun or similar weapon.4Office of the Law Revision Counsel. 18 USC 924 – Penalties Someone convicted of Hobbs Act robbery who brandished a gun faces at least 7 years on the firearm count alone, added onto whatever the robbery sentence turns out to be.
Aggravating Factors That Push Sentences Up
Within any statute’s range, several facts drive a sentence toward the top end. Whether anyone was physically injured carries the most weight; causing bodily harm can double or triple the effective penalty. Firearms draw harsher treatment than knives or blunt objects in most sentencing frameworks.
Where the robbery happened also matters. A home invasion is treated more severely than a store robbery because courts view the entry into a residence as an added violation. Targeting a vulnerable victim such as an elderly or disabled person is an aggravator in most jurisdictions. Working with accomplices, wearing disguises, or taking steps to avoid identification tend to increase the sentence as well.
Criminal history is often the single biggest sentencing driver outside the facts of the crime itself. A first offense gets significantly different treatment than a second or third, and habitual-offender statutes can escalate the result dramatically.
How Much Time Is Actually Served
The number a judge announces is not always the time spent behind bars, but armed robbery leaves less room for early release than most offenses.
Federal prison has no parole. Inmates can earn good-time credit of up to 54 days per year by following institutional rules, which brings actual time served to roughly 85 percent of the sentence imposed.5Office of the Law Revision Counsel. 18 USC 3624 – Release of a Prisoner A 20-year federal sentence means roughly 17 years served. Mandatory minimums added by a § 924(c) firearm enhancement, however, are not eligible for good-time reduction; those years are served day for day.
State systems vary. Some retain parole for violent offenses, some have abolished it, and some restrict eligibility specifically for armed robbery. Where parole exists, a defendant typically has to serve a set percentage of the sentence or a minimum number of years before becoming eligible, and that threshold is often higher for armed robbery with a firearm than for other felonies.
After federal prison, supervised release follows. For the felony classes covering most armed robbery convictions, supervised release can last up to five years.6Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment You have to avoid new offenses, submit to drug testing, and comply with any other conditions the court sets, including restitution payments. A violation can send you back to prison.
Consequences Beyond Prison
A felony conviction for armed robbery sets off a chain of consequences that outlast the prison term. Federal courts must order restitution to victims for property losses, medical costs, and other damages caused by the crime; it is mandatory rather than discretionary.7Office of the Law Revision Counsel. 18 USC 3663A – Mandatory Restitution to Victims of Certain Crimes That financial obligation can follow you for years.
Federal law permanently bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.8Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Armed robbery clears that threshold in every state, and violating the ban is itself a separate felony. Voting rights vary; some states restore them after the sentence is complete, others impose longer or permanent restrictions.
Anyone convicted of a federal felony must provide a DNA sample to the Bureau of Prisons, and the same requirement applies during supervised release or probation. Refusing is a separate misdemeanor.9Office of the Law Revision Counsel. 34 USC 40702 – Collection and Use of DNA Identification Information From Certain Federal Offenders Most states have similar collection requirements for violent felony convictions.
On the employment side, licensing boards in many states can deny, revoke, or suspend professional licenses after a felony conviction, particularly where the offense relates to the duties of the profession. Healthcare, law, education, finance, and security are commonly affected. Even in jobs that do not require a license, background checks will show the conviction, and many employers screen out violent felony records.
Immigration Consequences for Non-Citizens
For non-citizens, the stakes are higher still. Federal immigration law classifies any “crime of violence” carrying a sentence of at least one year as an aggravated felony.10Office of the Law Revision Counsel. 8 USC 1101 – Definitions Armed robbery fits in every case. A non-citizen convicted of an aggravated felony is deportable regardless of how long they have lived in the United States, and that classification eliminates most forms of relief from removal.11Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
