If you or someone you love is doing time in Wyoming, the release date depends on three components working together: a court-imposed minimum and maximum sentence, good time credits that can reduce both, and a discretionary decision by the Wyoming Board of Parole. Wyoming is one of the few remaining states that uses a traditional indeterminate sentencing system with no sentencing guidelines. The court prescribes a minimum and a maximum term. Good time - up to 15 days per month - reduces the minimum to produce an earlier parole eligibility date and reduces the maximum to shorten the projected discharge date. The Board of Parole makes a discretionary decision at the parole eligibility date. For eligible parolees, parole good time of up to 20 days per month can further reduce the time spent on supervision.
This guide walks through how Wyoming calculates a release date step by step: the minimum and maximum sentence structure, how good time works and what it affects, special good time from the Board, parole eligibility and the Board's role, parole supervision and parole good time, and life sentences. None of this is legal advice, but it will help you read your own time the way the Wyoming Department of Corrections does.
Here is the short version.
Wyoming uses indeterminate sentencing. The court prescribes a minimum and a maximum term. Good time - awarded by the WDOC warden at up to 15 days per month for proper conduct and program participation - reduces both the minimum and maximum sentence. Good time earned on the minimum determines the parole eligibility date; good time earned on the maximum determines the projected discharge date (the outer limit). Typically, offenders become parole eligible after serving approximately two thirds of their full minimum sentence (which reflects the effect of maximum good time reducing the minimum by half). The Board of Parole makes a discretionary decision at the parole eligibility date. If parole is granted, the person is supervised for the remainder of the maximum sentence; parole good time of up to 20 days per month may further reduce that supervision period. If parole is never granted, the person is released at the maximum minus good time.
Step one: the minimum and maximum sentence
Wyoming courts are required by law to prescribe both a minimum and a maximum term when imposing a sentence for a felony conviction. There are no sentencing guidelines; the court has broad discretion in setting both numbers within the statutory ranges.
The minimum defines when parole eligibility is first possible, after accounting for good time credits. The maximum defines the outer limit of state control - the point by which the person must be released from prison or supervision if nothing else has produced an earlier release.
A typical Wyoming felony sentence might be stated as a minimum of 3 years to a maximum of 6 years, or a minimum of 5 years to a maximum of 10 years. Both numbers matter for the release date calculation, and good time applies to each separately.
The Wyoming Board of Parole is independent of the Wyoming Department of Corrections and has authority over release decisions, conditions, and revocations.
Step two: good time - up to 15 days per month
Good time is the central mechanism for reducing a Wyoming sentence before the projected parole eligibility date and before the maximum discharge date.
The WDOC warden may award good time to an inmate who has maintained a proper and helpful attitude, conduct, and behavior. Good time is earned at a rate of up to 15 days per month for each month served.
Good time awarded for prison time reduces both the minimum and the maximum sentence. This is a key feature: every month of good time earned affects both the parole eligibility date (by reducing the minimum) and the outer discharge date (by reducing the maximum).
Good time is also awarded for time served in the county jail before transfer to WDOC, including credit for time served in accordance with the Judgment and Sentence and time between sentencing and transfer.
At admission, the WDOC calculates two projected dates based on full potential good time:
Projected parole eligibility date: calculated by applying full potential good time to the minimum sentence.
Projected discharge date: calculated by applying full potential good time to the maximum sentence.
These projected dates are administrative calculations, not guarantees of good time being awarded.
Good time can be removed by either the WDOC or the Wyoming Board of Parole for an inmate who fails to demonstrate proper attitude, conduct, and behavior. Removal of good time pushes both the parole eligibility date and the discharge date back.
Because good time can reduce the minimum by up to 50 percent, offenders who maintain the maximum good time rate typically become parole eligible after serving approximately two thirds of the full minimum sentence - reflecting the combined effect of good time reducing the minimum.
Step three: special good time - Board award for exceptional conduct
In addition to regular good time from the WDOC, the Wyoming Board of Parole may award special good time to recognize exceptional institutional performance.
Special good time reduces the minimum sentence only (not the maximum). The Board may award up to one month of special good time for every year in length of the minimum sentence, with a maximum reduction of one year of the minimum, in addition to the regular monthly good time.
The Board may also award up to one year of special good time regardless of minimum length - but only for the specific purpose of paroling the person to an adult community correction program, intensive supervision program, drug court, or other established community treatment program. This provides a mechanism for the Board to accelerate parole for those who need structured community supervision rather than continued incarceration.
Special good time is awarded based on an especially proper and helpful attitude and exemplary conduct and behavior - a higher standard than the good attitude required for regular good time.
Step four: the Wyoming Board of Parole
The Wyoming Board of Parole has operated as an independent state agency since 2003. The Board has 7 members appointed by the Governor to 6-year terms. No more than 4 members may belong to the same political party. Members work part-time.
The Board schedules offenders approximately one and one quarter years before their earliest parole eligibility date. Hearings to grant parole are conducted at each of the five WDOC facilities and two adult community corrections facilities on a regular schedule. In addition to two hearing sets per month, the Board also holds a quarterly administrative meeting.
The Board evaluates multiple factors in deciding whether to grant parole, including the nature of the offense, the offender's institutional conduct and attitude, program participation and case plan compliance, risk assessment, the impact on victims, and the proposed release plan.
Parole is discretionary - reaching the parole eligibility date does not guarantee release. The Board grants parole when it concludes that the person is ready for supervised community reintegration.
The Board also has authority to: remove good time from inmates as a sanction for misconduct; set conditions of parole; revoke parole based on violations; and make commutation recommendations to the Governor.
The Board works with certified victims to provide notification of parole hearings and opportunities for victim input.
Step five: parole supervision and parole good time
When parole is granted, the person is released to community supervision for the remainder of the maximum sentence. Supervision is provided by agents of the Wyoming Department of Corrections.
On the parole term, the person can earn parole good time - a separate credit category that is higher than prison good time. Parole good time can be awarded at up to 20 days per month for each month served on parole, based on compliance with the conditions of parole. This is awarded at the Board's discretion.
Parole good time reduces the maximum sentence, shortening the overall supervision period. It is calculated near the end of parole and provides the Board with an opportunity to reward compliance with an earlier discharge.
Parolees who demonstrate sustained compliance may also be eligible for early termination of supervision before the maximum discharge date. The Board may grant release from active supervision when it appears no useful purpose would be served by continuing supervision.
If parole is revoked for a violation, the person may be returned to prison for a period up to the remainder of the maximum sentence.
If parole is never sought or never granted, the person is released from prison at the maximum sentence date minus accumulated good time.
Step six: no sentencing guidelines, mandatory minimums, and habitual offenders
Wyoming has no sentencing guidelines. The court has broad discretion in setting minimum and maximum terms within the statutory ranges for each offense.
Certain offenses carry mandatory minimum sentences that the court cannot sentence below. Where a mandatory minimum applies, the parole eligibility date cannot arrive until the mandatory minimum has been served, regardless of what good time might otherwise produce.
Repeat violent felony offenders may be convicted as habitual criminals under Wyoming's habitual offender law. In that case, they face a mandatory minimum term before parole eligibility that is set by statute and is substantially longer than the ordinary minimum for the underlying offense.
There are no separate parole eligibility formulas for violent offenses or sex offenses. The same good time framework applies across offense categories, except where a mandatory minimum overrides the normal calculation.
Putting it together: a worked example
Here is how the pieces fit, using examples. None of these numbers are legal advice, but they show the method.
Take a person sentenced to a minimum of 3 years and a maximum of 6 years for a felony. At admission, WDOC calculates projected dates. With full good time (15 days/month), the minimum is reduced by approximately 50 percent, so the projected parole eligibility date is approximately 18 months (1.5 years). With full good time on the maximum, the projected discharge date is approximately 3 years. If the Board grants parole at 18 months, the person serves the remaining time on parole under supervision. With parole good time (up to 20 days/month), the maximum discharge date can be reduced further, potentially allowing discharge from supervision well before the 3-year projected maximum discharge date.
If the Board denies parole at 18 months, future hearings are scheduled until either parole is granted or the person reaches the projected discharge date of 3 years.
The bottom line for Wyoming
Wyoming's release date is shaped by three layers of credits and a discretionary Board. The WDOC warden awards regular good time (up to 15 days/month), which reduces both the minimum and maximum, producing a projected parole eligibility date and a projected discharge date. The Board may award special good time (up to 1 year) for exceptional performance, further reducing the minimum. The Board makes a discretionary parole decision at the eligibility date. On parole, good time of up to 20 days/month can further reduce the maximum. Mandatory minimums and habitual offender provisions apply for specific offenses and override the normal good time calculation.
The practical takeaways are clear. First, maintain proper attitude and program compliance at all times - good time is earned month by month and can be lost for misconduct. Second, understand that good time reduces both the parole eligibility date and the projected discharge date; protecting it protects both. Third, prepare a strong parole plan - the Board schedules hearings about a year before the earliest eligibility date, so the plan should be ready well in advance. Ask the Wyoming Department of Corrections for the current projected parole eligibility date, accumulated good time, and projected discharge date.
Frequently asked questions
How is a release date calculated in Wyoming?
Wyoming uses indeterminate sentencing. The court prescribes a minimum and maximum term. Good time of up to 15 days per month reduces both. The reduced minimum produces the parole eligibility date; the reduced maximum produces the outer discharge date. The Board of Parole makes a discretionary decision at the parole eligibility date. If parole is granted, parole good time (up to 20 days/month) can further reduce the maximum supervision period.
What is good time in Wyoming?
Good time is awarded by the WDOC warden at up to 15 days per month for proper attitude, conduct, and participation in programs. It reduces both the minimum and maximum sentence. Because good time can cut the minimum by up to 50 percent, offenders typically become parole eligible after serving about two thirds of their full minimum. Good time can be removed by WDOC or the Board for misconduct.
What is special good time in Wyoming?
Special good time is an additional reduction of the minimum sentence awarded by the Wyoming Board of Parole for exceptional conduct. The Board may award up to one month of special good time for every year of the minimum sentence, up to a maximum of one year beyond regular good time. The Board may also award up to one year of special good time to facilitate a parole to a community treatment program, drug court, or intensive supervision.
Does Wyoming have parole?
Yes. The Wyoming Board of Parole is an independent state agency that makes discretionary parole decisions. It schedules offenders for hearings approximately one and one quarter years before their earliest parole eligibility date. The Board evaluates conduct, programming, risk, victim impact, and the release plan. Parole is not guaranteed at the eligibility date.
What is parole good time in Wyoming?
Parole good time is awarded at the Board's discretion during supervision - up to 20 days per month for compliance with parole conditions. It reduces the maximum sentence, shortening the total supervision period. It is calculated near the end of parole. A parolee may also be eligible for early termination of supervision when the Board determines continued supervision serves no useful purpose.
What are mandatory minimums in Wyoming?
Certain Wyoming offenses carry mandatory minimum sentences that the court cannot reduce. Where a mandatory minimum applies, parole eligibility cannot arrive before the mandatory floor is served, regardless of good time. Repeat violent felony offenders convicted under the habitual offender law face mandatory minimums set by statute that are substantially longer than ordinary minimums for the underlying offense.
