Conditional Release (Parole) Calculator
Known in Turkish as both koşullu salıverilme and şartlı tahliye, conditional release (parole) is granted after a convict serves a set proportion of the sentence under Article 107 of Act No. 5275. This tool covers only the general 1/2 ratio for ordinary sentences.

Suç tarihine göre geçici madde farkları, açık/kapalı kurum durumu ve infaz hâkimliği/Cumhuriyet Başsavcılığı kararı sonucu değişebilir.

The Good Conduct Assessment
Conditional release does not occur automatically once a set proportion of the sentence has been served; the convict's good conduct in the institution must also be assessed by the administration and observation board, and the execution judge must issue a decision to that effect (Article 107 of Act No. 5275).
Difference from Supervised Release
Supervised release allows a convict of good conduct with one year or less left until conditional release to serve, on request, the remaining part of the sentence up to that date outside the institution (Article 105/A); conditional release itself is the principal mechanism that ends enforcement of the sentence. Since Law No. 7550 took effect on 4 June 2025, the convict must also have spent in the institution at least one tenth of the time required until conditional release, and no less than five days. The tool also shows the earliest date of supervised release under the general rule.
Deduction of Time Spent in Pretrial Detention or Custody
Time spent in pretrial detention, in custody, or under any other measure restricting personal liberty before the judgment becomes final is deducted directly from the prison sentence imposed (Article 63 of the Criminal Code), so that a person does not experience the same deprivation of liberty twice. In this tool, the number of days to be deducted is entered as a separate field and is subtracted directly from the enforcement period required.
How Does the Transition to Supervised Release Happen?
Supervised release does not begin automatically. The law requires a request by a convict of good conduct who is in an open institution or a juvenile education centre (or could not move to one for reasons beyond their control), an assessment report by the institution, and a decision of the execution judge (Art. 105/A). For offences committed up to 30 March 2020, the one-year period is applied as three years, except for the offences excluded by transitional Article 6. Throughout the period, the convict must comply with obligations set by the execution judge (which may include electronic monitoring, periodic sign-ins, or attending an education or work programme); breaching these obligations can lead to the supervised release being revoked.
Key Concepts in Sentence Enforcement
| Concept | Explanation |
|---|---|
| Conditional release | Release after serving the statutory proportion of the sentence in the institution (Art. 107) |
| Supervised release | On request, serving the period up to conditional release outside the institution once one year or less remains (Art. 105/A) |
| Good conduct | The assessment by the administration and observation board underlying the release decision |
| Recidivism | A prior final conviction; it changes both the ratio and the conditions |
Key Dates in the Enforcement Process
| Stage | Explanation |
|---|---|
| Entry into enforcement | The date the sentence actually begins being served in the institution |
| Deduction | Time in pretrial detention/custody is deducted before enforcement begins (Criminal Code Art. 63) |
| Start of supervised release | At the earliest one year before conditional release, and only after at least one tenth of the required period (no less than five days) has been served (Art. 105/A, Law No. 7550) |
| Conditional release | Once the statutory proportion of the sentence (1/2 in the general case) has been served (Art. 107) |

Frequently Asked Questions
Is the conditional release ratio the same for every offense?
No; the general ratio is 1/2, but higher ratios apply to certain offenses such as terrorism, drug trafficking, and sexual offenses.
Does recidivism change the ratio?
Yes; recidivism provisions affect both the ratio and eligibility for certain rights. This tool does not calculate recidivism cases.
Does everyone qualify for supervised release?
No; it requires the convict's request, good conduct, being in (or eligible for) an open institution, the institution's assessment report and an execution judge's decision. This tool only shows the earliest possible date.
Is pretrial detention time deducted from the sentence?
Yes; time spent in pretrial detention or custody before the judgment became final is deducted from the sentence to be served (Criminal Code Art. 63).
How is the deductible period documented?
Pretrial detention or custody periods are recorded by the court and the prison administration; the enforcement prosecutor's office accounts for this period automatically when enforcement begins. The same number of days should also be entered in this tool.
Is electronic monitoring mandatory during supervised release?
Not always; the execution judge may set electronic monitoring and other obligations, such as sign-ins or an education/work programme, depending on the convict's circumstances.
What happens if the supervised release obligations are breached?
A breach of the obligations can lead to the supervised release order being revoked and the remaining period being served in the institution.
If the required enforcement period is under one year, does supervised release apply?
It can. A convict with one year or less left until conditional release may benefit, but since 2025 they must first have served at least one tenth of the required period in the institution, and no less than five days (Art. 105/A).
