The life expectancy of a concentration camp prisoner was calculated by the SS Economic Department to be nine months. The Economic Department supplied slave labor from the camps to German industries such as Krupp, Volkswagen, Messerschmidt, AEG, IG Farben, Rheinmetal, and Siemens, according to their request.
The SS economic Department received six marks per day for every slave laborer. According to the calculations of the SS, as recorded in a document exhibited at the International War Crimes Trials in Nuremberg, the SS income from every slave laborer amounted to 1,631 marks for the 270 days of his service to the German war machine, after deducting food and clothing expenses, and includeing an additional income of 200 marks for the valuables, which were found on the body, as well as the ashes and bones of the disposed body which were sold for fertilization.
