The displayed costs are not based on company figures but on estimated or statistical values and relate to a utilization of the equipment of ... % (based on a working time of 24 hrs. per day and 365 day in a year). A better utilization of the equipment (if possible) may lead to superproportional savings.

Major cost components like plant- or waste costs may be missing, because we were not able to ascertain them. To facilitate an easier comparison we have default settings in many process for the unit prices (e.g. labour, power, water, etc.) of 1 Euro. You may put in your real values, but also your real consumptions (use the dot as separating mark). Thus comparison of different processes will be easier. Printing should be done in landscape format.
