Statutory Formulas Explained

Criminal sentences are structured by jurisdiction-specific penal statutes governing how time is accounted for:

New York Determinate (CPL § 70.02 / § 70.04 / Correction Law § 803)

Under NY State law for violent felonies, individuals are sentenced to a fixed determinate term plus mandatory Post-Release Supervision (PRS). Individuals are eligible for good behavior allowances of up to one-seventh (1/7th) of the term, meaning a minimum of six-sevenths (85.7%) must be served before conditional release.

Federal Sentencing Reform (18 U.S.C. § 3624(b) / First Step Act)

Federal prisoners may receive up to 54 days per year of good conduct credit (approximately 85% truth-in-sentencing service requirement). The First Step Act allows additional earned time credits for qualifying non-violent participants in recidivism-reduction programming.

Jail Time Credit (NY CPL § 70.30(3))

Time spent in pre-trial detention or detention prior to the commencement of sentence is credited against both the minimum period of imprisonment and the maximum term of an indeterminate sentence, and against the determinate term.

Consecutive vs. Concurrent Structuring

When multiple counts or convictions across different courts (such as New York and California) are involved:

Consecutive Stacking (Multi-Jurisdiction)

When sentences are ordered consecutive, the second sentence does not begin until the minimum or complete custody obligation of the preceding sentence has expired or been discharged by statute.

Post-Release Supervision (PRS)

Upon conditional release or maximum expiration of prison, the individual enters mandatory community supervision. A violation during PRS can return the individual to prison for the unexpired balance.

Limitations and Appellate Adjustments

Statutory aggregate caps (e.g., NY Penal Law § 70.30 consecutive violent felony aggregates) can automatically reduce nominal consecutive totals by operation of law. Consult formal commitment papers.
