Good Time Credit Calculator

Calculate federal Good Conduct Time (GCT) under 18 U.S.C. § 3624(b) at 54 days for each year of the sentence imposed, including the First Step Act correction that replaced the BOP's earlier 47-days-per-year calculation.

Good conduct time basics

GCT applies only to sentences longer than one year.
The rate is 54 days per year of the sentence imposed, not per year served.
Disciplinary sanctions can result in disallowed or forfeited good conduct time, which pushes the release date later.
GCT is applied before First Step Act earned time credits.

Frequently asked questions

How many days of good time per year in federal prison?

54 days per year of the sentence imposed, for sentences of more than one year.

Can good conduct time be taken away?

Yes. A disciplinary hearing officer can disallow or forfeit good conduct time for prohibited acts, which moves the projected release date later.
