Anti death penalty folks claim that the death penalty costs $2.1 million dollars more than a life sentence in North Carolina.
This sticks as one of the more widely used cost deceptions by the anti death penalty crowd.
True life cases are more expensive than death penalty cases, as per the Duke Study. (1)
As per the Duke study, the difference in cost between a "life" sentence and a death sentence is from $163, 459 - $216, 461. (Table 9.1, page 77)
However, in the study, a "life" sentence is only 20 years. You need to add at least 20 years or $332, 000/case to get a true life sentence (my analysis). The Duke study "present valued" incarceration costs at $16, 600/year. (Tables 8.1, page 71 & 9.1, page 73)
The authors also concede leaving out geriatric care, recently found to be $60,000-$90,000/yr/prisoner (various studies). Add $225,000 per case, present valued at $15, 000/year/case for 15 years (my analysis). Geriatric care begins at age 50-55 for prisoners.
The authors should have calculated the cost savings of plea bargains to a life sentence in 20% of the death eligible cases, which accrues as a cost savings for the death penalty. Rough estimate of $40,000 cost saving per plea bargain (an average of $8000/case or 20% of $40,000.) (my analysis, although I think the number is too low).
What the study really tells us is that an actual life sentence costs much more than a death sentence.
The study finds that it costs $2.16 million per execution, if you roll the cost of every death penalty cases into only one execution. Specifically, if you have 10 death penalty cases at an "extra cost" of $216, 461/per case, over the cost of a "life" sentence, and you execute 1 of those 10 cases, then the study says that every execution costs $2.16 million more than a single life case.
It's absurd, of course.
One could be just as misleading and state that it costs $3.48 million per completed true life sentence (death of inmate), over the cost of a death sentence case, if you roll the cost of every true life case into only one death. Specifically, if you have 10 true life cases at an extra cost of $348,539/per case, over the cost of a death sentence, and 1 of those 10 lifers had died, then every completed true life case costs $3.48 million more than a single death sentenced case. (2)
Just as absurd and misleading, but that is just how that $2.16 million figure was calculated.
NOTE: This highly deceptive presentation of the death penalty costing $2.1 million dollars more than a life sentence has been used extensively and very publically by anti death penalty activists, for many years. I have found no evidence that the authors of the study ever tried to correct this obvious perversion of their study, although I would find it very hard to believe that they were unaware of it.
Incredibly, New Mexico's irresponsible and/or dishonest Legislative Finance Committee used this Duke study as the only one to show that the death penalty was more expensive than life without parole.

(2) The $348, 539, reflects the cost a true life sentence over the death penalty, based upon costs and credits for true life incarceration (add $332,000 for life), geriatric care (add $225, 000 for life ), & plea bargain savings ($8000 death penalty credit)combined with the studies <$216, 461>. or $565, 000 - $216, 461 = $348,000 more for a true life sentence. My analysis.
