Federal Sentencing Guidelines: A Plain-English Overview

When a federal judge imposes a sentence, the starting point is usually the Federal Sentencing Guidelines, a detailed framework published by the United States Sentencing Commission. The guidelines do not dictate a single number. Instead, they produce a recommended range, such as 41 to 51 months, based on the specifics of the case.

The system works through two main inputs: the offense level and the criminal history category. The offense level reflects how serious the crime is, with adjustments for factors like the amount of money involved in a fraud case or the quantity of drugs in a trafficking case. The criminal history category reflects the defendant's prior record, from first-time offenders to those with extensive histories. Where those two numbers intersect on the guidelines' sentencing table is the recommended sentencing range.

It used to be that the guidelines were mandatory, with judges required to stay within the range except in narrow circumstances. That changed in 2005, when the Supreme Court ruled that mandatory guidelines violated the Sixth Amendment. Since then, the guidelines have been advisory. Judges must still calculate the range correctly and consider it, but they have discretion to sentence above or below it.

That discretion is not unlimited. Judges are required to weigh the factors listed in the federal sentencing statute, things like the nature of the offense, the defendant's history, the need for deterrence, and the need to avoid unwarranted disparities between similar defendants. When a judge departs from the guideline range, the reasons are typically explained on the record.

In practice, most federal sentences still fall within or near the guideline range. Prosecutors and defense attorneys both build their sentencing arguments around it, presenting evidence about which adjustments should apply. A difference of a few offense levels can move the recommended range by years, so these calculations are often the most contested part of the sentencing process.

The guidelines are updated periodically, and amendments can change how certain offenses are scored. Because the version in effect at the time of sentencing generally applies, the timing of a case can matter.
