I don't remember where it came from but I did save a chart that I got from one of my training classes and now use it for my own training classes. The amount of rework required to make up for incident/injury losses depends on the profit margin required by the employer. I tried pasting the chart on this forum board, but could not get it to work, so here is my best attempt without a tables chart.
If you work at a 3% profit margin, $1,000 in yearly losses will require $33,000 in new work to make up for the losses. $5,000 in yearly losses will require $167,000 in new work to make up for the losses. $10,000 in yearly losses will require $333,000 in new work to make up for the losses, etc. Other profit margins would be calculated similarly. Most common indirect costs I've seen are rework, down time, replacements, training and company image, but these are very hard to put into a calculation model. If you would like a copy of the full chart, I would be glad to e-mail it.
