determinate sentence

Definition from Nolo’s Plain-English Law Dictionary

A jail or prison sentence that is definite and not subject to review by a parole board or other agency. For example, a sentence of six months in the county jail is determinate, because the prisoner will spend no more than six months (minus time off for good behavior, in some situations). By contrast, an indeterminate sentence (such as 20 years to life) has a minimum term but the release date, if any, will be chosen by a parole board as it periodically reviews the case.
