Federal Sentencing Guidelines work by combining an offense level with a defendant's criminal-history category to produce a recommended sentencing range. Federal judges must calculate and consider that range, but it is advisory rather than mandatory. The Guidelines are the U.S.
Sentencing Commission's nationwide framework for people convicted of federal crimes. The Commission's current Guidelines Manual took effect Nov. 1, 2025.

How the offense level is calculated
The court starts with the Chapter Two guideline for the offense of conviction. That guideline supplies a base offense level, which serves as the calculation's starting score. The court then applies relevant offense characteristics and adjustments.
These may address victim impact, the defendant's role, obstruction, multiple counts and acceptance of responsibility, according to the Sentencing Commission's explanation of the calculation process. The resulting total offense level reflects more than the offense's name. Two defendants convicted of the same federal crime can receive different total levels when the applicable facts and adjustments differ.
How criminal history affects the range
The court separately determines the defendant's criminal-history category under Chapter Four. It then finds where that category intersects with the total offense level on the Sentencing Table. That intersection produces a recommended imprisonment range stated in months.
The Commission's 2025 Sentencing Table therefore makes both parts of the calculation important: the same offense level can produce a different range when the criminal-history category changes. The table is not the final sentence. It establishes the advisory range that the judge must consider alongside federal statutes and the circumstances of the case.
Why judges can sentence outside the range
After united States v. Booker, the Guidelines are advisory. A judge must calculate them correctly and consider the result, but may impose a sentence outside the range through a variance. Federal law also requires consideration of the factors in 18 U.S.C.

§3553(a). These include the offense, the defendant's characteristics, available sentences, deterrence, public protection, rehabilitation, sentencing disparities and victim restitution. The governing standard is a sentence sufficient, but not greater than necessary, to serve those statutory purposes. A Guidelines calculation can therefore anchor the decision without dictating it.
When federal statutes override the calculation
Statutory sentencing limits control when they conflict with the calculated range. If a mandatory minimum exceeds the range, that minimum becomes the guideline sentence. If the statutory maximum is lower, it caps the sentence.
This distinction is crucial when estimating possible exposure. A low calculated range cannot displace a higher mandatory minimum, and a high range cannot authorize imprisonment beyond the statutory maximum. The Guidelines also address more than prison. Depending on the applicable range and governing law, Chapter Five covers probation, supervised-release conditions, fines, restitution and other sentencing options.
What changed for personal characteristics in 2025
In 2025, the Commission removed departure provisions and policy statements concerning specific personal characteristics. A departure is a Guidelines-based reason for moving outside the calculated range. That change did not bar judges from considering those facts.
The Commission said personal characteristics may still inform a §3553(a) variance, as explained in the 2025 Guidelines Manual's introductory chapter. The practical distinction is where the argument fits. A characteristic may no longer support one of the removed departure provisions, yet remain relevant to the judge's individualized statutory analysis.
What to examine in a sentencing estimate
A useful sentencing estimate should identify each controlling part of the analysis: A Guidelines range alone is therefore incomplete. Anyone assessing a federal sentence should verify the underlying calculation, the statutory limits and the individualized factors the judge may consider.
