How We Calculated P. Diddy’s Prison Release Date: It’s Sooner Than You Think

Sean Combs was sentenced on October 3, 2025, to 50 months in federal prison after being convicted of two Mann Act counts involving transportation to engage in prostitution. Public reporting states that he had been detained since his September 16, 2024 arrest, and that the Bureau of Prisons later listed a projected release date of February 23, 2028.

This article explains how Prison Law Firm would break down the math under a set of favorable assumptions. It also explains a major First Step Act issue that lawyers should be fighting: whether qualifying work, teaching, programming, or other productive activities completed during detention before arrival at the designated BOP prison can count toward FSA time credits.

The Short Answer

Using the assumptions in this article, there are two ways to model the date:

The conservative date is the cleaner planning date. The aggressive model is the litigation position. The aggressive model should not be ignored, especially if Combs was working, teaching, mentoring, completing classes, or otherwise engaged in documented productive activities while detained.

The Four Key Numbers

Step 1: Start With the 50-Month Sentence

Combs was sentenced on October 3, 2025. A 50-month sentence measured from that date reaches approximately December 3, 2029.

But that is not the practical release-date starting point because Combs had already spent substantial time in federal custody before sentencing.

Step 2: Account for Good Conduct Time

Federal prisoners serving more than one year may generally earn up to 54 days of good conduct time for each year of the sentence imposed. That is the familiar reason many federal sentences are discussed as roughly 85% sentences.

Public reporting originally placed Combs’ projected BOP release date around May 8, 2028, before later reports stated that the BOP projected date moved to February 23, 2028. Because the BOP has not publicly explained every administrative adjustment, this article uses the earlier May 8, 2028-style baseline as a conservative working date before layering the requested assumptions for RDAP, FSA, and Second Chance Act placement.

Step 3: Apply the RDAP Assumption

The Residential Drug Abuse Program, commonly called RDAP, can produce up to a 12-month sentence reduction for eligible individuals who successfully complete the program. RDAP is not automatic. The BOP determines eligibility, admission, completion, and the amount of early release.

For this calculation, we assume the best-case RDAP result: 365 days off.

There is one practical limitation: the BOP generally will not award the final RDAP early release benefit unless the person successfully completes RDAP. So even if the math produces an earlier theoretical date, the actual transfer or release plan may depend on when RDAP is completed.

Step 4: Apply First Step Act Time Credits

The First Step Act allows eligible federal prisoners to earn time credits for successful participation in Evidence-Based Recidivism Reduction programs and Productive Activities. The basic rate is 10 days of credit for every 30 days of successful participation. Eligible minimum- or low-risk prisoners who maintain that status over two consecutive assessments may earn an additional five days, for a total of 15 days for every 30 days of successful participation.

For this article, we use the requested assumption:

• First 6 months: 10 FSA days per 30 days
• Remainder of the qualifying period: 15 FSA days per 30 days

The Big FSA Fight: Does Detention-Period Activity Count?

This is the issue lawyers should not concede.

The BOP has historically taken the narrow position that First Step Act time credits do not begin until an eligible person arrives at the designated BOP facility where the sentence will be served. Under that view, a person sitting in a jail, detention center, private contract facility, or holdover facility before BOP designation may lose months of possible credit-earning time.

But that BOP position is being challenged. Recent appellate decisions have recognized that the issue is not as simple as “no BOP arrival, no FSA credits.” The statutory argument comes from 18 U.S.C. § 3585(a), which says a federal sentence commences when the defendant is received in custody awaiting transportation to the official detention facility where the sentence will be served.

In plain English: if a person has already been sentenced and is being held while waiting for BOP transport or designation, lawyers should consider arguing that the FSA clock has started.

There may also be a more aggressive argument when someone completed meaningful work, teaching, programming, mentoring, education, or other productive activity in federal detention before arrival at the designated prison. That argument will depend heavily on the circuit, the facts, BOP documentation, and whether the activity can be tied to a qualifying Evidence-Based Recidivism Reduction program or Productive Activity.

Questions Lawyers Should Ask About Detention-Period FSA Credits

For Combs, or any federal defendant in a similar position, the FSA detention-credit fight should begin with documents and timelines.

• What exact dates was the person in custody before sentencing?
• What exact dates was the person in custody after sentencing but before arrival at the designated BOP prison?
• Was the person working in any jail job?
• Was the person teaching, mentoring, tutoring, or facilitating any course?
• Was the person participating in classes, counseling, programming, religious programming, education, or treatment?
• Was the activity documented by jail staff, counselors, case managers, chaplains, teachers, or BOP personnel?
• Can the activity be tied to an Evidence-Based Recidivism Reduction program or Productive Activity?
• Did the person later receive a PATTERN risk score that would make the credits usable?
• Does the controlling circuit support challenging the BOP’s refusal to consider those credits?

Lawyers should not assume the BOP will volunteer these credits. The stronger approach is to preserve the issue, request the records, exhaust administrative remedies if necessary, and litigate when the facts and law support it.

Step 5: Apply Six Months of Second Chance Act Prerelease Custody

The Second Chance Act allows the BOP to place people in prerelease custody near the end of the sentence, often through a Residential Reentry Center, commonly called a halfway house. Home confinement is more limited by statute, but six months of prerelease custody is a common planning target when discussing halfway house or halfway-house-to-home-confinement placement.

For this calculation, we use six months as approximately 183 days of prerelease custody.

The Conservative Formula

In the conservative model, we start from the May 8, 2028-style good-conduct-time baseline and assume FSA credits begin at or after sentencing rather than from the full detention period.

Then we plug in the assumptions:

For FSA credits:

• First 6 months: 60 days of FSA credits
• After that: 15 days for every 30 days, or roughly 0.5 credit days for each additional custody day

Solving that equation produces approximately 287 to 288 days of secure custody after sentencing before transfer. October 3, 2025 plus approximately 287 to 288 days lands around July 17–18, 2026.

The Aggressive FSA Litigation Model

The aggressive model asks whether Combs should receive additional FSA credit for documented productive activities during detention before arrival at his designated BOP facility.

This is not automatic. It is a fight. It depends on whether the activity qualifies, whether the period legally counts, whether the BOP accepts the argument, and whether a court in the relevant circuit agrees.

Using the full disputed detention period as a hypothetical only, the additional credit argument could look like this:

If those additional disputed credits were recognized, the modeled transfer date could move substantially earlier than July 2026. In a full-credit aggressive model, the paper date could land in early 2026.

Because that date may already have passed, the practical argument would be that the BOP should immediately review the sentence computation, apply any supported credits, and determine whether Combs is already eligible for prerelease custody, subject to RDAP completion and placement rules.

Why We Do Not Simply Subtract Every Possible Credit From the Current BOP Date

Public reports state that the BOP projected Combs’ release date moved to February 23, 2028. That is the date the public should watch because it reflects what the BOP is reportedly showing at that time.

But a public BOP projected release date may already include some credits, good conduct time, administrative changes, or sentence-computation updates. That means it would be a mistake to blindly subtract one year of RDAP, all possible FSA credits, and six months of prerelease custody from the reported BOP date unless counsel knows exactly what the BOP has already applied.

In plain English: do not double count credits.

Our Bottom Line

Using the conservative assumptions in this article, Prison Law Firm estimates that Sean “P. Diddy” Combs could be transferred to a halfway house or home-confinement-style prerelease placement around July 18, 2026.

Using the aggressive FSA litigation model, if lawyers can prove qualifying detention-period productive activity and persuade the BOP or a court to recognize those credits, the paper date could move earlier, potentially making him eligible for immediate review depending on RDAP completion and BOP placement rules.

The final answer depends on several moving parts:

• The official judgment and sentence computation
• Actual presentence detention credit
• Good conduct time
• FSA eligibility
• PATTERN risk level
• Documented programs, work, teaching, or productive activities
• Whether detention-period activity is recognized
• RDAP eligibility and completion
• Second Chance Act placement approval
• Discipline history
• Appeal outcome
• BOP administrative decisions
