Felony classes are the tiers criminal codes use to rank serious crimes by severity, with each class carrying its own range of prison time and fines. Federal law sorts felonies into five classes, A through E, under 18 U.S.C. § 3559. Most states use a similar lettered or numbered ladder, though the labels and penalties vary from one state to the next. Knowing which class a charge falls into tells you the maximum prison exposure, the potential fine, and a good deal about how prosecutors and judges will handle the case.
The Five Federal Classes
Federal law assigns every felony a letter based on the maximum prison term the offense allows:
- Class A: life imprisonment or death. This covers the most serious federal crimes, including murder, large-scale drug trafficking, and treason.
- Class B: twenty-five years or more but less than life. Offenses like kidnapping and major fraud schemes often fall here.
- Class C: at least ten years but less than twenty-five. Serious drug distribution and certain firearms offenses sit in this range.
- Class D: at least five years but less than ten. Many mid-level drug crimes and some white-collar offenses carry Class D penalties.
- Class E: more than one year but less than five. This is the lowest federal felony tier and covers offenses like smaller-scale fraud and certain regulatory violations.
These brackets set the ceiling, not the floor. A judge sentencing a Class C felony can impose anything from probation up to twenty-four years, depending on the circumstances. The § 3559 classification kicks in as a default when Congress hasn’t assigned a specific letter to a crime in the statute that defines it.
On the money side, 18 U.S.C. § 3571 caps individual fines at $250,000 for any felony conviction, regardless of class. Organizations face a $500,000 ceiling. Both limits can be overridden two ways: the specific statute defining the crime may set a higher fine, or the court can impose a fine equal to twice the financial gain the defendant received or twice the loss victims suffered, whichever is greater. In fraud and trafficking cases, that alternative regularly produces fines in the millions, with restitution to victims layered on top.
How States Organize Felonies
States take one of three general approaches. Many use a lettered system, grouping offenses from Class A (most serious) down through Class D, E, or F. Others prefer numbers, ranking crimes from Class 1 through Class 5 or 6. A handful of states skip classification altogether and assign a specific penalty range to each individual crime in the statute that defines it. In those states, you look up the crime itself to find the prison range rather than matching a class label to a sentencing chart.
The internal logic isn’t consistent across borders. In most lettered systems, Class A is the top of the severity scale. In most numbered systems, Class 1 is the most serious. But because each state writes its own criminal code, the same label can mean very different things depending on where you are. A Class C felony in one state might carry five to ten years, while a Class C in another carries two to five. The specific jurisdiction matters far more than the letter or number attached to a charge.
What Each Tier Looks Like in Practice
High-Level Felonies
High-level felonies sit at the top of any classification ladder, whether labeled Class A, Class 1, or a state equivalent. These charges involve conduct that caused or risked the most serious harm: homicides, sexual assaults, large-scale drug trafficking, kidnapping, and armed robbery. Prison sentences at this level routinely start at twenty years and can reach life without parole.
Federal Class A carries the possibility of life in prison or the death penalty. Class B starts at twenty-five years and can stretch to just under life. The distinction between the two often comes down to whether someone died and whether the defendant acted with premeditation. A drug trafficking operation that moves enough product to trigger the highest quantity thresholds under 21 U.S.C. § 841 can push what might otherwise be a Class B offense into Class A territory, with a ten-year mandatory minimum floor and a ceiling of life imprisonment.
Mid-Level Felonies
Mid-level felonies occupy Classes C and D at the federal level, and their state equivalents generally carry sentences between five and twenty years. These are serious crimes, but they lack the extreme violence or scale that pushes charges to the top tier. Aggravated assault where the victim recovered, burglary of an occupied building, robbery without a firearm, and distribution of controlled substances in quantities below the highest mandatory-minimum thresholds all tend to land here.
The practical difference between mid-level and high-level charges often turns on specific facts: whether a weapon was used, how much drugs were involved, how badly someone was hurt. A robbery with a knife that causes no injury might be a Class C felony carrying up to twenty years, while the same robbery with a gun that seriously injures the victim could jump to Class B. Prosecutors have significant discretion in choosing which class to charge, and that choice shapes plea negotiations from day one.
Low-Level Felonies and Wobblers
Low-level felonies are the entry point of the felony system. Federal Class E covers offenses with a maximum sentence between one and five years. State equivalents go by labels like Class D, E, Class 5, or Class 6. These charges tend to involve property crimes, lower-level fraud, certain drug possession offenses, and regulatory violations. The prison terms are the shortest available for felonies, but the conviction still carries the full weight of a felony record.
This is where the line between felony and misdemeanor gets blurry. Many states recognize “wobbler” offenses that prosecutors can charge as either a felony or a misdemeanor depending on the circumstances. The decision often turns on the defendant’s criminal history, the dollar amount involved, and the specific facts of the case. A first-time shoplifter who steals just over the felony threshold might get a misdemeanor charge; someone with prior convictions for the same conduct might face a felony. Some states also let judges reduce a wobbler felony to a misdemeanor at sentencing or after probation is completed. Federal law does not recognize wobblers in the same way; federal crimes are classified strictly as felonies or misdemeanors.
Capital Offenses
Capital offenses occupy a special position. Federally, they fall within Class A rather than forming a separate category, but the stakes are fundamentally different because the death penalty is on the table. Many states treat capital crimes as a distinct classification outside their standard lettered or numbered system.
The Supreme Court has narrowed which crimes can carry a death sentence. In Kennedy v. Louisiana (2008), the Court held that the Eighth Amendment bars the death penalty for crimes that did not result in, and were not intended to result in, the victim’s death. That effectively limits capital punishment to murder and a handful of offenses against the state like treason and espionage. Even within eligible offenses, the government must prove at least one statutory aggravating circumstance under 18 U.S.C. § 3592, and a jury must unanimously decide that death is the appropriate sentence. In states that have abolished capital punishment, the most serious offenses instead carry mandatory life imprisonment without parole.
Why the Class Is Only the Ceiling
Felony classifications set the maximum sentence, but two other layers determine what a defendant actually receives.
Mandatory minimums set the floor. Congress and state legislatures have attached mandatory prison terms to specific offenses, removing judicial discretion to impose anything lighter. These minimums most commonly apply to drug trafficking and firearms crimes. Federal drug trafficking minimums under 21 U.S.C. § 841 are triggered by the type and quantity of the substance involved, with thresholds measured by the total weight of the mixture containing the drug rather than the pure drug weight.
Repeat offender laws push sentences higher still. The federal three-strikes provision under 18 U.S.C. § 3559(c) imposes mandatory life imprisonment on anyone convicted of a serious violent felony who has two or more prior convictions for serious violent felonies or serious drug offenses. The Armed Career Criminal Act at 18 U.S.C. § 924(e) imposes a fifteen-year mandatory minimum on anyone convicted of illegal firearm possession who has three prior convictions for violent felonies or serious drug crimes.
Within those statutory boundaries, federal sentencing runs through the U.S. Sentencing Guidelines. The Sentencing Commission publishes tables that calculate a recommended range based on the seriousness of the offense (an “offense level” that accounts for factors like dollar amounts, weapon use, and victim harm) and the defendant’s criminal history category. Since United States v. Booker (2005), the guidelines are advisory rather than mandatory. Judges must calculate the range and consider it alongside the broader sentencing factors in 18 U.S.C. § 3553(a), but they can go above or below it and explain why. The upshot is that two defendants convicted of the same Class C felony can receive very different sentences depending on their record, their role in the offense, and the judge.
Consequences That Follow Any Felony
The felony class determines prison time and fines, but a felony conviction triggers a cascade of consequences that outlast any sentence and hit regardless of whether the conviction was Class A or Class E.
Firearms
Federal law permanently bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition. The ban under 18 U.S.C. § 922(g)(1) applies to all felony convictions, state or federal, and has no expiration date. Violating it is itself a federal felony carrying up to fifteen years in prison.
Voting Rights
Felony disenfranchisement is governed entirely by state law, and the rules vary enormously. Some states restore voting rights automatically upon release from prison, others require completion of parole or probation, and a few require a governor’s pardon or individual petition. Two states and the District of Columbia never revoke voting rights, even during incarceration.
Employment
A felony record creates significant employment barriers, but blanket bans on hiring people with convictions are legally risky for employers. EEOC enforcement guidance holds that an automatic, across-the-board exclusion from employment based on any criminal conviction is inconsistent with Title VII of the Civil Rights Act. Employers are expected to consider the nature of the crime, the time that has passed, and the nature of the job before making a hiring decision. Many states and cities have also enacted “ban the box” laws that prohibit asking about criminal history on initial job applications.
Education and Housing
Federal student aid eligibility is no longer affected by drug convictions. Students who are currently incarcerated face limitations, but those restrictions end upon release, and individuals on probation or parole may be eligible for federal financial aid. Housing is a different story. Landlords in the private market routinely screen for criminal records, and while federal fair housing guidance discourages blanket exclusion policies, enforcement is inconsistent.
International Travel
Several countries, most notably Canada, routinely deny entry to individuals with felony records. Approval for expedited travel programs like TSA PreCheck and Global Entry can also be denied based on criminal history. Certain convictions, particularly drug trafficking offenses, can lead to passport revocation.
Clearing a Felony Record
The federal government currently has no general mechanism for expunging or sealing federal felony convictions. At the state level, the picture is more promising. Most states offer some form of expungement or record sealing for at least some felony offenses, though eligibility typically depends on the class of felony, the type of crime, and how much time has passed since the sentence was completed. A growing number of states have adopted “Clean Slate” laws that automate the expungement process for eligible records, eliminating the need to hire a lawyer and file a petition. These laws generally exclude the most serious felony classes, violent offenses, and sex crimes. For anyone carrying a felony conviction, checking the specific eligibility rules in the state where the conviction occurred is the essential first step.
