Sentencing Guidelines Estimator

Estimates a federal sentencing guidelines range using the U.S. Sentencing Commission's offense level and criminal history category framework (USSG §5A Sentencing Table).

Base Offense Level (1–43)

Total Offense Level Adjustments (can be negative)

Criminal History Category (I–VI)

I (0–1 point) II (2–3 points) III (4–6 points) IV (7–9 points) V (10–12 points) VI (13+ points)

Statutory Mandatory Minimum (months, 0 if none)

#### Formula & Methodology

Total Offense Level = Base Offense Level + All Adjustments (clamped to 1–43)

Guideline Range = USSG §5A Sentencing Table lookup [Total Offense Level × Criminal History Category]

Effective Range = max(Guideline Min, Mandatory Minimum) to max(Guideline Max, Mandatory Minimum)

Sentencing Zones (USSG §5C1.1):

Zone A (0–6 months): Probation permitted.
Zone B (1–15 months): Probation with at least 1 month confinement condition permitted.
Zone C (8–24 months): Split sentence — at least half served in prison.
Zone D (15+ months): Imprisonment required.
