How Release Dates Are Calculated in Kansas

If you or someone you love is doing time in Kansas, the release date is built on a sentencing grid and one rule that surprises most families: good time credits in Kansas do not shorten the total sentence. They move time from prison to post release supervision. The amount of prison served goes down, but the time spent on post release supervision in the community goes up by the same number of days. The total sentence length stays the same.

This guide walks through how Kansas calculates a release date step by step: how the sentencing grid works, what good time credits do and how the shift between prison and post release supervision operates, what post release supervision looks like and how long it lasts, and how off grid offenses with life sentences work differently. None of this is legal advice, but it will help you read your own time the way the Kansas Department of Corrections does.

Here is the short version.

Kansas adopted the Kansas Sentencing Guidelines on July 1, 1993, making sentencing determinate for most felonies. The court imposes a sentence in months based on where the crime severity level and the person's criminal history meet on the sentencing grid. Good time credits of 15 percent or 20 percent of the prison term are available depending on the offense severity level. Earning those credits shortens the time in prison but adds the same number of days to post release supervision. After release, post release supervision is mandatory, and its length is set by severity level. The Prisoner Review Board handles revocations and sets supervision conditions. Off grid offenses such as certain murders carry life sentences with mandatory minimums and are reviewed by the Board after the mandatory minimum is served.

Step one: the sentencing grid

Kansas sentencing since July 1, 1993 is organized around two grids: one for nondrug offenses and one for drug offenses. Both grids work the same way.

The vertical axis of each grid shows the crime severity level, from level 1 (most severe) to level 10 for nondrug offenses or level 5 for drug offenses. The horizontal axis shows the offender's criminal history category, from category A (most extensive) through category I (no prior felony convictions). The intersection of the severity level and criminal history category produces a grid box.

Each grid box contains three numbers, all in months. The center number is the standard presumptive sentence - the length a judge would normally impose. The two numbers flanking it represent the range within which the judge can sentence without issuing what is called a departure sentence. If a judge departs from the grid - sentencing above or below the range for documented reasons - that departure can be appealed.

The grid boxes are also color coded. Boxes in the darker zone indicate that prison is presumptive. Boxes in the lighter or yellow zone indicate that probation or an alternative to prison is presumptive, though the judge still has discretion. At the intersection of a border box, the judge can choose either prison or probation.

Two columns to the right of the grid boxes show the post release supervision length and the maximum good time percentage for each severity level. These two columns are often overlooked but are essential for projecting the release date.

Step two: good time credits and the time shift rule

Good time credits are earned by avoiding disciplinary actions while serving the prison term. Understanding them requires understanding one rule that is unique to Kansas: the credits move time between prison and post release supervision, they do not eliminate it.

For most on grid offenses at nondrug severity levels 1 through 6 and drug severity levels 2 and 3, the maximum good time is 15 percent of the prison portion of the sentence. For less severe offenses at nondrug severity levels 7 through 10 and drug severity levels 4 and 5, the maximum good time is 20 percent of the prison portion.

Here is the key mechanic. When good time is earned and retained, it is subtracted from the prison term. But that same number of days is added to the post release supervision term. On a 100-month sentence with 15 percent good time, a person earns 15 months of credit. The prison term drops from 100 months to 85 months. The post release supervision term goes up by 15 months from whatever it would otherwise have been. The person serves the same total sentence - just fewer months behind walls and more months in the community.

Good time credits can be forfeited for disciplinary violations, abuse of the judicial process (such as filing false claims), or other misconduct. A forfeiture means more time in prison, not a reduction in post release supervision. Credits lost must be rebuilt through continued compliance.

For sex offenses, the statute requires that any time subtracted from the prison portion through good time must be added to the post release supervision term. This is especially important for sex offense cases because post release supervision for those offenses can already be lengthy.

Step three: post release supervision

Post release supervision is automatic for everyone sentenced to prison on an on grid sentence. It is not a discretionary grant - it is a mandatory part of the sentence, and its length is built into the grid.

The right side of the sentencing grid shows the number of months of post release supervision for each severity level. The lengths vary by severity level, and they are added to whatever time the person serves in prison to produce the total sentence period. As described above, good time earned in prison does not reduce the post release supervision period - it extends it by the amount credited.

During post release supervision, the Kansas Department of Corrections supervises the person in the community through the Bureau of Community Corrections. Conditions are set by the Prisoner Review Board and may include reporting requirements, restrictions on travel and associations, drug and alcohol testing, employment requirements, and participation in programming. If post release supervision is revoked for a violation, the person is returned to prison. For violations that are not new criminal convictions, the revocation term is capped at 90 or 180 days depending on when the crime was committed and other factors. For new felony or misdemeanor convictions, the revocation can result in serving a longer period.

For certain drug offense convictions, post release supervision does not apply after a specified date depending on the statute of conviction.

Sex offenders on post release supervision face heightened requirements including treatment programs and, for the most serious sexual offenses, supervision terms that can extend for decades.

Step four: off grid offenses and the Prisoner Review Board

Some Kansas crimes are so serious that they fall outside the sentencing grid entirely. These are called off grid offenses.

Off grid crimes include certain murders and other specified serious violent offenses for which Kansas prescribes a life sentence with a mandatory minimum term. The most well-known is the Hard 25 rule - a mandatory minimum of 25 years before parole eligibility - though the specific mandatory minimums vary by offense and offense date.

For off grid offenders serving life sentences with mandatory minimums, the Kansas Prisoner Review Board reviews the case after the mandatory minimum is served and decides whether to grant parole. This is discretionary, unlike the automatic release that applies to on grid sentences. The Board evaluates risk, institutional conduct, and the potential impact on public safety. If parole is denied, the Board sets a future review date.

For crimes committed before July 1, 1993, the old indeterminate sentencing law still governs. Those offenders also come before the Prisoner Review Board for parole consideration after serving the court-imposed minimum, less good time credits. For those sentences from before the guidelines, good time can allow parole eligibility as early as after serving half of the court-imposed minimum.

The Prisoner Review Board also sets conditions for all individuals on post release supervision, handles violation hearings and revocations, and can grant early discharge from supervision for successful compliance.

Putting it together: a worked example

Here is how the pieces fit, using a simple example. None of these numbers are legal advice, but they show the method.

Take a person sentenced to 48 months in prison for a nondrug severity level 5 offense. Level 5 falls within the 15 percent good time category. With maximum good time, the person earns 15 percent of 48 months, or 7.2 months of credit (approximately 7 months). That credit is subtracted from the prison term: 48 months minus 7 months equals approximately 41 months in prison. Those same 7 months are added to the post release supervision period. If the level 5 post release supervision term is 24 months, it becomes 31 months. The person serves about 41 months in prison and then about 31 months on post release supervision - a total of 72 months, the same as the original 48-month prison sentence plus the standard 24 month post release term.

Now consider an off grid offense resulting in a life sentence with a Hard 25 mandatory minimum. The person must serve 25 years before the Prisoner Review Board will consider parole. There is no automatic release, and the Board's decision is discretionary. If parole is denied, the Board sets a future review, and the process continues.

The bottom line for Kansas

Kansas release dates are determined by the sentencing grid and the good time credit rules. The court imposes a sentence in months based on the crime severity level and criminal history. Good time credits of 15 or 20 percent reduce the prison term but extend post release supervision by the same amount. The total sentence does not shrink - it shifts. Post release supervision is mandatory after every on grid prison term. Off grid life sentences are different: the Prisoner Review Board reviews them after the mandatory minimum and exercises discretionary release authority.

The practical takeaways are clear. First, understand the time shift rule: good time moves time to post release supervision, it does not eliminate it. Second, earn and protect good time credits through clean conduct, because each lost credit day means an additional day in prison. Third, know the post release supervision length and conditions, because violations can return a person to prison. Ask the Kansas Department of Corrections for the sentence computation showing the prison release date, the post release supervision end date, and the current good time credit balance.
