RDAP Calculator
Estimate the effect of the federal Residential Drug Abuse Program (RDAP) on a release date. Eligible participants who complete the program may receive a sentence reduction of up to 12 months under 18 U.S.C. § 3621(e), on top of Good Conduct Time and First Step Act credits.
RDAP in practice
- RDAP is a nine-month residential treatment program followed by community treatment.
- The reduction is discretionary and capped at 12 months; shorter sentences typically receive a smaller reduction.
- A documented substance use disorder within the 12 months before arrest is generally required.
- Certain offenses, particularly those involving violence or weapons, are excluded from the early release benefit.
- Sentences under roughly 48 months often leave too little time to complete the program and receive the full reduction.
Frequently asked questions
How much time does RDAP take off a federal sentence?
Up to 12 months for eligible participants who complete the program, at the BOP's discretion. Shorter sentences usually receive less.
Can I get both RDAP and First Step Act credits?
Yes. RDAP participation can also count as programming for First Step Act earned time credits, and the reductions stack.
