Overview

About the Incident Cost Calculator

OSHA $afety Pays model — direct + indirect cost per incident. Indirect costs (investigation, lost productivity, training replacement, morale) run 1.1× to 4.5× direct cost depending on severity. Revenue-needed calculation shows sales required at your profit margin to offset the incident cost.

Used in safety ROI business cases, board reports, and insurance negotiations. Aligns with OSHA's published $afety Pays estimator.

Formula
Total = Direct + (Direct × indirect-ratio)

Worked examples

Incident Cost Calculator — real-world examples

$10,000 medical-treatment incident at 10% margin

Direct $10K + indirect $11K (1.1× ratio) = $21K total. Revenue needed to net $21K at 10% margin = $210K. A reportable medical case costs roughly 20× its direct medical cost in net revenue impact.
