73030.18.2.16 Good time Credits Available – Line 6

  • Inmates earn good time credits from July 1, 1977 or from the received date if after July 1, 1977. A one-third reduction of sentence is allowed. To compute this reduction of sentence with a calculator the following formula is used:

    • Enter the unadjusted maximum DSLDeterminate Sentence Law date.

    • Subtract the received date, or July 1, 1977, whichever is later.

    • Add the number of days granted as post-sentence credit if the post-sentence credit is for time in custody on/after July 1, 1977.

    • Divide by 3 = total goodtime/worktime credits available. This calculation may result in a fraction of either one-third or two-thirds. When this happens, the prisoner is given a full day (the fractional number is raised to the next whole number.)

    • Enter into memory of the calculator.

    • Divide by 4 = days of participation credit (round off to the nearest whole number).

    • Multiply PCPenal Code x 3 = days of goodtime credit (round off to the nearest whole number).

    • Record this figure in the “Goodtime Credits Available” space.
