About Sentence Calculator


Sentence Calculator, a criminal law sentencing aid, seeks to provide all personnel involved in sentencing review with a simple, easy-to-use tool that quickly performs the complex calculations often required to determine accurate release dates – particularly those within the framework of the laws contained in the various sections of Article 70 of the New York State Penal Law.

How It Works

Conceived of and developed by Terry Davidson, Sentence Calculator is the culmination of an automated system created, refined and used by Mr. Davidson to address clients’ needs for timely, accurate and reliable information regarding potential and actual sentencing impact.

Now, Sentence Calculator is available to legal and judicial professionals, legal assistance and educational institutions, corrections personnel and any individual who may be affected in some way by a criminal sentence.

Sentence Calculator is user-friendly and requires only that subscribers input basic, essential information – for example: the sentence date, actual length of the sentence and days spent in jail by the client while awaiting sentencing. The state-of-the-art system then takes on the task of performing complex logic and calculations behind the scenes, ultimately presenting the user with final results and release dates. The system has been designed for use by legal assistants, paralegals, court clerks and anyone who has access to accurate input data.

Subjected to thorough and ongoing testing based on actual New York State Department of Corrections and Community Supervision (DOCCS) case studies, Sentence Calculator has benefited from consultation with experts from all aspects of the legal, judicial, enforcement and educational fields. In addition, our system is continually updated with regards to changes in the penal law.
