Estimate your advisory federal imprisonment range using the 2024 U.S. Sentencing Guidelines, plus Good Conduct Time, First Step Act credits, and RDAP.
Federal courts use the U.S. Sentencing Guidelines to set an advisory imprisonment range. This calculator maps your final offense level (1–43) and Criminal History Category (I–VI) to the range published in Chapter 5, Part A of the 2024 Guidelines Manual, then applies eligible credits: up to 54 days per year of Good Conduct Time, First Step Act earned time credits, and up to 12 months for RDAP.
For the raw table with all 43 offense levels and six criminal history categories, see the Federal Sentencing Guidelines Chart. For plain-english definitions of every term, see the Sentencing Glossary.
