The problem in one sentence
Congress passed a law in December 2018 that lets most federal prisoners earn time credits for completing recidivism-reduction programs, and the Bureau of Prisons has spent the years since struggling to calculate, post, and apply those credits correctly. Reporting by Forbes contributor Walter Pavlo and the consulting group Prisonology documented an implementation, in their words, plagued with computer problems — and families around the country have watched projected release dates swing by weeks or months with no explanation.
The consequences are not abstract. People have been held past the date the law entitled them to go home. Others lost halfway house placements because credits posted late. And because the BOP rarely explains its own math, most families never find out whether the number on the books is right. That is the gap this site exists to close: we teach you how to read the computation, spot the errors, and use the free procedures Congress and the Constitution already give you.
What First Step Act time credits actually are
Under 18 U.S.C. §3632(d)(4), an eligible person in federal custody earns 10 days of time credits for every 30 days of successful participation in evidence-based recidivism reduction (EBRR) programs or productive activities. A person who has been assessed at minimum or low risk of recidivism on the PATTERN tool for two consecutive assessments earns at the enhanced rate of 15 days per 30. Earning is not tied to a single class: the BOP treats successful participation as engaging in assigned programming during a given period, so credits accrue steadily for people who follow their individualized needs plan.
Applying credits is a second, separate step governed by 18 U.S.C. §3624(g). Up to 365 credits can be applied to move the release date itself earlier — technically, an early transfer to supervised release. Every credit beyond that ceiling can be applied toward prerelease custody: placement in a residential reentry center (halfway house) or home confinement. There is no statutory cap on the prerelease-custody side, which is why a person with a long sentence and consistent programming can earn a year off plus many additional months at home before the sentence formally ends.
Earning credits vs. applying credits — the distinction that decides cases
Most family confusion, and a surprising number of BOP errors, come from collapsing two different questions into one. Earning asks: is this person legally allowed to accumulate credits, and is the BOP posting them at the correct rate? Applying asks: has this person met the separate statutory conditions for the credits to actually change a date? A person can be earning perfectly and still see no movement in the release date because an application condition is unmet — or vice versa.
To apply credits toward early release, the statute generally requires that the person have a minimum or low PATTERN risk level (or a warden’s individualized approval in limited circumstances for prerelease custody), that earned credits equal the remainder of the sentence, and that no disqualifying detainer or final order of removal blocks application. When a family tells us the credits are there but the date will not move, the answer almost always lives in this list. Our guide to FSA eligibility and our PATTERN score explainer walk each condition in detail.
Who is excluded — and who only thinks they are
Congress wrote a long list of disqualifying convictions into 18 U.S.C. §3632(d)(4)(D) — offenses involving violence, terrorism, sex offenses, certain firearm crimes, and certain high-level drug offenses, among others. If the offense of conviction appears on that list, the person cannot earn FSA credits at all, although good conduct time under §3624(b) still applies. The list turns on the offense of conviction, not on conduct described in the presentence report, and that distinction matters enormously.
We regularly hear from families told, informally, that a loved one is ineligible when the actual judgment says otherwise. Case managers are handling enormous caseloads and mistakes happen. The fix starts with paper: get the judgment and commitment order, compare the statute of conviction against the exclusion list, and if there is a mismatch, raise it in writing. Our page on which offenses qualify includes the practical steps for challenging a wrongful ineligibility determination through the administrative remedy program.
How to audit the BOP’s math from outside the fence
Every person in BOP custody has a sentence computation record and, since the First Step Act, an FSA Time Credit Assessment that shows credits earned, credits applied, and the resulting dates. The person inside can request these from their case manager or unit team at any program review, and can send copies home through the mail or summarize them over Corrlinks. Since late 2024 the computation also displays an FTC Conditional Placement Date, which projects when prerelease custody should begin if earning continues.
Your audit asks four questions in order. One: is the person coded as eligible, and should they be? Two: is the earning rate right — 10 or 15 days per 30 — and did the enhanced rate start when the second consecutive minimum/low assessment posted? Three: do the months of participation multiply out to the credits shown, including retroactive credit back to the law’s effective period? Four: are applied credits actually reflected in the projected release date and the conditional placement dates? Our free FSA calculator produces an independent estimate you can hold up against the BOP’s numbers, and our release-date guide shows where to find every figure.
When the numbers are wrong: the escalation ladder
The system gives you a ladder, and it must usually be climbed in order. The first rung is informal: the person inside raises the discrepancy with the case manager, in writing, and asks for a corrected computation or an explanation of the math. A surprising share of errors die here, because a specific written question — my judgment shows 21 U.S.C. §841(b)(1)(C), which is not an excluded offense; why am I coded ineligible? — is much harder to wave off than a general complaint.
If informal resolution fails, the Administrative Remedy Program begins: a BP-8 informal resolution attempt, a BP-9 to the warden, a BP-10 appeal to the regional office, and a BP-11 appeal to the central office, each with strict deadlines measured in days. Exhausting this process is not busywork — federal courts generally require it before they will hear a sentence-computation challenge, and the paper trail it creates becomes the factual record if court ever becomes necessary. Keep copies of everything, on both sides of the fence.
The courthouse door: 28 U.S.C. §2241, filed pro se
When the BOP denies relief through the final administrative appeal — or simply fails to respond within its own deadlines, which counts as a denial — the lawful next step is a petition for habeas corpus under 28 U.S.C. §2241. A §2241 petition challenges the execution of a sentence rather than its validity, which makes it exactly the right vehicle for time-credit and computation disputes. It is filed in the federal district where the person is confined, it names the warden as respondent, and the filing fee is five dollars.
People win these. Federal courts have ordered the BOP to recalculate credits, to apply credits it wrongly withheld, and in cases where correct application meant the sentence was already over, to release the petitioner. The person in custody signs and files the petition personally — that is what pro se means, and it is a right, not a workaround. Our role is education: we publish plain-English explainers, self-help workbooks, and formatting guidance so the filer understands every element of the process. We do not draft arguments for anyone’s case, and this page is not legal advice; it is a map of a public road.
What families can do this week
Start the paper file today. Ask your loved one to request their current sentence computation and FSA Time Credit Assessment at the next unit team contact and to mail copies home. Pull the projected release date from the BOP’s public inmate locator and write it down with the date you checked — you are building a timeline, and dates that move without explanation are evidence. Run our calculator with the real sentence figures and note any gap between its estimate and the BOP’s numbers.
Then get educated before you escalate. Read the pro se guide so the process holds no surprises, and the miscalculation playbook for the specific error patterns we see most. If you want structured help, our membership tiers include the full template library, procedural coaching, and — at the top tier — a quarterly informational review of the computation records you gather. And if the situation involves questions only a lawyer can answer, we will say so plainly and point you toward finding post-conviction counsel.
The honest part: what this fight can and cannot do
FSA advocacy recovers real time, but it is bounded by the statute. It cannot make an excluded offense eligible, cannot push the early-release application past 365 days, and cannot force the BOP to place someone in a specific halfway house on a specific date — placement decisions under 18 U.S.C. §3621(b) are largely insulated from court review. Anyone who promises otherwise, at any price, is selling something the law does not contain.
What the fight reliably can do is force the math to be right. The statute is mandatory about earning rates and application once conditions are met, and courts have shown they will hold the BOP to it. Every week of delay in checking the numbers is potentially a week of liberty lost at the back end. That asymmetry — low cost to verify, enormous cost to ignore — is the entire reason this site leads with this page.
