Federal Custody Date Estimator
A simple educational timeline tool for families.
Important: This is not an official BOP sentence computation, legal advice, or a release-date determination. It does not calculate Good Conduct Time, First Step Act time credits, jail credit, forfeitures, ineligibility, RRC placement, home confinement, or other adjustments. Always rely on official BOP records and your sentencing documents.
Basic sentence timeline
This tool only adds the entered number of calendar months to the entered start date. It intentionally does not subtract credits or predict prerelease custody.
Before relying on any date
Compare any estimate with the official BOP inmate record, sentence computation, judgment, and applicable law. Questions about credit disputes, eligibility, disciplinary forfeitures, or legal deadlines may require counsel or the BOP administrative remedy process.
