Here is a calculator that hit my husbands release date right on the nose. I see everyone is asking about it hope it helps :)

(i tried to put the calculator here code did not work)

1 Choose whether you will calculate Federal Prison or State Prison sentence. Each State Prison Department of Corrections (DOC) has a different algorithm for sentence computation as does the Federal Bureau of Prisons (BOP)

Federal Prison Sentence: If you select "Federal" you would need to annotate Yes or No for RDAP - explained in item 2. This sentence is automatically figured as the Board Of Prisons uses only 1 calculation for good time credit.

State Prison Sentence: If you select "State Prison" a drop down box will appear and you will simply choose the state of sentencing.

2 If you are choosing a Federal BOP sentence click here for "Yes". You'll notice that R.D.A.P is set to "No" automatically. This is due to not knowing if you are eligible for a drug or alcohol treatment program. If you are you might be able to shave even more time off of your incarceration. If you are eligible for R.D.A.P. (Residential Drug Abuse Program - it has longer names but we'll stick with this), then choose "Yes". You'll also notice that R.D.A.P ( is highlighted - this is for more information as it pertains to the treatment program and facilities.

3 Often the "Date of Surrender" is not necessary when using the state prison calculation. For the Federal system you'll put in your "Date of Surrender". If you surrender at 2pm it will actually count as a full day... so its best to add this date.

4 If you had been incarcerated for any length of time, put that amount in here. This is the amount of time you have already served; such as county lockup, transfer etc. This time will be deducted from your total time. As well, it will also be counted as "good time" as this reflects your sentence as a whole. Please check with your probation officer or attorney to find out if your state has different rules about time spent being incarcerated while waiting for trial or transfer. For the Years, Months or Days - you can enter any amount or figure. So if you spent 1 year in county you can put 12 in the months box. This prison calculator understands all dates.

5 This one is pretty straightforward with one exception: You can enter a number of Years and/or Months and/or Days; or simply the number of Years, or, the number of Months, or, the number of total Days... or mix up any amount. So if your sentence was 48 months you can simply put the number "48" in the months box. Or - you can put "4" in the years box - or 1,460 days.

6 Once you have all of your figures entered click on "Calculate My Good Time" and the prison calculator will change showing you the results of your time to serve, your total days and your possible release date.

hmm thanks that's interesting that gave me a date of 2018 and he had actually mention something about 5 years from now if they ever give him good time, but im not holding my breath for either of those dates.

It was way off for me. It was almost 3 years over. It doesn't give you the option to put in percentages nor does it calculate milestone credits.

Interesting. When I tried to put in the 16 months, it gave us out date of 08/2012, but he is getting half time and it does not let me put that in there. So I put in 8 months and it is giving us an out date of 01/2012 (which would be AWESOME) but I am pretty sure his out date will be sometime in May 2012 (don't have release date yet :( )

Is there no way to tell it he is only doing 50% of his time?! :confused:
