Sorry if this is the wrong spot for this; Joel feel free to move it.

Back in 1998 OSHA wrote a piece of software to assist employers in assessing the impact of occupational injuries and illnesses (with Lost Work Days) on their profitability. It uses a company's profit margin, the AVERAGE costs of an injury or illness, and an indirect cost multiplier to project the amount of sales a company would need to generate in order to cover those costs.

The software is downloadable from their site and comes in a zip file. The link to this free software is;

It uses your company's profit margin to determine the cost but will default to a nominal 3% if you don't know or don't want to plug in the correct figure.

The software will, after you indicate a type of injury, spit out the average direct cost of the injury, the average indirect costs, and the estimated total costs.

The employer and his insurer always pays the direct costs on a shared basis. The employer alone pays for the indirect costs. I suggest you refer to the notes included in the download for more information.
