Indirect costs
The cost of time lost from work (or leisure) and decreased productivity due to disease, disability, or death. In cost accounting, refers to costs that cannot be attributed to a particular activity but can be allocated across different activities; may be “fixed” regardless of activity intensity (e.g., building maintenance) or “variable” where their magnitude varies with activity (e.g., heating and lighting a building)
Intangible costs
the cost of pain and suffering resulting from a disease, condition, or intervention
