How OSHA’s “Safety Pays” cost method works
OSHA’s Safety Pays program exists to make the business case for safety: it shows that the money behind an injury is far larger than the medical bill. Every recordable injury carries two kinds of cost.
- Direct costs — the workers’-compensation and medical costs that flow through your insurance. These come from NCCI average lost-time claim data (NCCI average lost-time WC claim costs, policy years 2015-2017) published in OSHA’s estimator.
- Indirect (hidden) costs — lost productivity, hiring and retraining a replacement, accident investigation, repairs, schedule delays, OSHA-citation exposure, higher experience-modification (EMR) premiums, and lower crew morale. OSHA estimates these with an inverse-severity sliding ratio: the smaller the claim, the larger the multiplier.
Total injury cost = Direct + (Direct × indirect ratio)
Revenue to recover = Total injury cost ÷ net profit margin
A common myth is that indirect costs are a flat “3–6×” of direct costs. OSHA’s current estimator does not use a flat multiplier — it uses the sliding bands below, and most serious injuries land in the lowest (1.1×) band.
OSHA’s indirect-to-direct cost ratio (by claim size)
| Direct cost of claim | Indirect ratio | What it means |
|---|---|---|
| $0 – $2,999 | 4.5× | Minor first-aid-level claims carry the most hidden overhead, proportionally. |
| $3,000 – $4,999 | 1.6× | Mid-range claims. |
| $5,000 – $9,999 | 1.2× | Mid-range claims. |
| $10,000 and above | 1.1× | Most serious injuries fall here — indirect ≈ the direct cost again. |

Average direct cost by injury type
These are OSHA’s NCCI average lost-time workers’-compensation claim costs. Your claim may be higher or lower; the calculator uses these as a planning baseline.
| Injury | Avg direct cost | Est. indirect (1.1×) | Est. total |
|---|---|---|---|
| Amputation | $96,003 | $105,603 | $201,606 |
| Fracture | $54,856 | $60,342 | $115,198 |
| Burn | $47,192 | $51,911 | $99,103 |
| Crushing | $67,003 | $73,703 | $140,706 |
| Concussion | $54,571 | $60,028 | $114,599 |
| Electric Shock | $158,218 | $174,040 | $332,258 |
| Strain | $32,023 | $35,225 | $67,248 |
| Laceration / Puncture | $21,872 | $24,059 | $45,931 |
| Foreign Body (eye) | $21,959 | $24,155 | $46,114 |
| Respiratory Disorder | $41,013 | $45,114 | $86,127 |
| All Other Specific Injuries, NOC | $53,955 | $59,351 | $113,306 |
All figures are ≥ $10,000 direct, so each uses the 1.1× indirect band. Occupational cancer ($163,395) and fatality ($1,340,000) are estimates, not NCCI values, and are flagged as such in the tool.
Worked examples
1. One amputation, 4% net margin. Direct cost $96,003 → indirect $96,003 × 1.1 = $105,603 → total $201,606. At a 4% margin you’d need $5,040,150 in new sales just to break even — roughly 12× the maximum OSHA serious-violation penalty of $16,550.
2. One laceration requiring surgical repair, 5% net margin. Direct cost $21,872 → indirect $24,059 → total $45,931 → $918,620 of revenue to recover. Even a “minor” cut is a six-figure sales problem at thin margins.
What to do next (reduce these costs)
- Prevent the incident. A written HazCom program, accessible SDSs, correct secondary-container labels, and documented training are the cheapest dollars you will ever spend against a six-figure claim.
- Use the number to fund safety. Bring the PDF cost report to ownership or your broker — it reframes safety spend as loss-avoidance, not overhead.
- Protect your EMR. Fewer claims lower your experience-modification rate, which compounds savings on every future premium.
- Estimate the citation, too. Pair this with the OSHA Fine Calculator to see the penalty an inspection could add on top of the claim.
Frequently asked questions
Where does the Safety Pays formula come from?
OSHA's Safety Pays program estimates accident cost as direct costs (workers' comp, medical) plus indirect costs (lost productivity, training replacements, investigation, etc.). Direct costs are NCCI average lost-time workers'-comp claims (policy years 2015-2017). Indirect costs use OSHA's inverse-severity sliding ratio (4.5x under $3,000, 1.6x at $3,000-4,999, 1.2x at $5,000-9,999, 1.1x at $10,000+), not a flat multiplier. Actual costs vary by employer and incident.
What is the profit margin used for?
To show how much additional revenue a company must generate to cover the cost of an accident. A low profit margin means you need much more revenue to offset the same dollar loss—making safety investments more compelling.
Can I use this for HazCom-specific incidents?
Yes. Chemical exposures, inadequate training, or citation-related costs can be input as the direct cost. The calculator then shows total estimated cost and revenue needed to recover.
How do I reduce these costs?
Prevention: written HazCom program, SDS access, labeling, and training. Use our free audit checklist and program generator, and consider HazComFast for ongoing SDS and training documentation.
