How OSHA calculates the true cost of an injury
A workplace injury costs far more than the medical bill. OSHA's Safety Pays program splits the cost into two parts: the direct cost (medical treatment and workers'-compensation indemnity) and the indirect cost (lost productivity, overtime, hiring and training replacements, investigation time, equipment damage, legal fees, and higher insurance premiums). The calculator above uses OSHA's exact method:
- Direct cost. The medical + indemnity cost of the claim. Pick an injury type to use OSHA's published average, or enter your own amount.
- Indirect multiplier. OSHA applies a sliding ratio that is inverse to severity — the cheaper the claim, the higher the multiplier. A $2,000 claim carries a 4.5× indirect cost; a $50,000 claim carries 1.1×.
- Total cost. Direct + indirect = the real cost to the business.
- Sales to recover. Total cost ÷ your net profit margin = the new revenue you'd need just to break even on the incident.
OSHA's inverse-severity indirect-cost ratio
OSHA's current Safety Pays estimator does not use the old flat “3–6×” rule. It uses these bands, applied to the direct cost:
| Direct cost of the claim | Indirect-to-direct ratio |
|---|---|
| $0–$2,999 | 4.5× |
| $3,000–$4,999 | 1.6× |
| $5,000–$9,999 | 1.2× |
| $10,000+ | 1.1× |

Average direct cost by injury type
OSHA's published averages come from NCCI lost-time workers'-compensation claims, policy years 2015–2017. Every figure below sits in the $10,000+ band, so each uses the 1.1× indirect multiplier (total ≈ 2.1× the direct cost).
| Injury | Avg. direct cost | Est. total cost (×2.1) |
|---|---|---|
| Amputation | $96,003 | $201,606 |
| Electric shock | $158,218 | $332,258 |
| Crushing / caught-in | $67,003 | $140,706 |
| Concussion | $54,571 | $114,599 |
| Fracture | $54,856 | $115,198 |
| Burn (chemical / thermal) | $47,192 | $99,103 |
| Respiratory disorder | $41,013 | $86,127 |
| Heat prostration | $37,658 | $79,082 |
| Strain / back injury | $32,023 | $67,248 |
| Eye — foreign body | $21,959 | $46,114 |
| Laceration / puncture | $21,872 | $45,931 |

Worked examples
One chemical burn, 3% net margin, 50 employees. Direct cost $47,192 → indirect 1.1× = $51,911 → total $99,103. At a 3% margin that's $3,303,433 in sales just to break even — about $1,982 per employee.
A minor $2,000 laceration claim. Because it falls under $3,000, OSHA applies a 4.5× indirect ratio: indirect $9,000 → total $11,000. A small medical bill still costs the business five-and-a-half times its face value.
Don't forget the OSHA fine
The injury cost above is separate from any OSHA citation. If the incident reveals a violation, OSHA can add a penalty on top — up to $16,550 for a Serious violation and $165,514 for a Willful or Repeat violation, per violation (29 CFR 1903.15). Run the OSHA Fine Calculator and add it to the incident cost for your full exposure.
What to do next
- Prevent the next claim. A documented HazCom program, accessible SDS, and current GHS labels are the cheapest line item on this page.
- Quantify the ROI. Use the Safety Pays Calculator to compare expected injury cost against the cost of prevention.
- Find your gaps. Run the HazCom Audit Checklist before an inspector does.
Frequently asked questions
Where do the indirect cost multipliers come from?
From OSHA's current Safety Pays estimator, which applies a sliding indirect-to-direct ratio that is INVERSE to severity: direct cost under $3,000 → 4.5×, $3,000–4,999 → 1.6×, $5,000–9,999 → 1.2×, and $10,000 or more → 1.1×. (This replaces the older flat '3–6×' figure from Stanford / Business Roundtable literature — OSHA's estimator no longer uses a flat ratio.) Because the average direct cost of every serious injury here exceeds $10,000, each uses the 1.1× ratio. Indirect costs include lost productivity, training replacements, equipment damage, investigation time, legal fees, and increased insurance premiums.
What counts as a direct cost vs. indirect cost?
Direct costs are medical expenses and workers' compensation indemnity payments. Indirect costs include everything else: overtime to cover absent workers, hiring and training replacements, investigation time, equipment repair, legal fees, OSHA fines, increased insurance premiums (EMR), and lost productivity from affected coworkers.
How is the 'Revenue to Recover' number calculated?
Revenue to Recover = Total Cost ÷ (Profit Margin % ÷ 100). For example, a $100,000 total cost at a 3% profit margin means Total Cost ÷ 0.03 = $3,333,333 in additional revenue just to break even on the incident. This demonstrates why prevention is far cheaper than accidents.
Can I use this for HazCom-related incidents?
Yes. Chemical burns, eye injuries, respiratory disorders, and heat illness are all common HazCom-related incidents. Use this tool alongside the OSHA Fine Calculator to see both the injury cost and the potential citation penalties — the fine is usually only a fraction of the total incident cost.
Is the OSHA fine included in this cost?
No. This calculator estimates the injury cost (medical, indemnity, and indirect business costs) using OSHA Safety Pays. An OSHA citation penalty is separate — a Serious violation can add a five-figure penalty and a Willful or Repeat violation a six-figure penalty, per violation, at current 2026 federal rates. Add the OSHA Fine Calculator estimate on top of the incident cost for the full exposure.
Where do the average direct costs come from?
They are OSHA's published Safety Pays estimator figures — NCCI average lost-time workers' compensation claim costs for policy years 2015–2017. For example, the average direct cost is about $96,003 for an amputation, $54,856 for a fracture, and $47,192 for a burn. Choose 'Custom' to enter your actual claim cost instead.
How do I reduce workplace incident costs?
Implement a comprehensive HazCom program: maintain accessible SDS, proper GHS labeling, regular training, and chemical inventory management. Use our free HazCom Audit Checklist to identify gaps, and consider HazComFast for ongoing digital compliance management. Prevention is far cheaper than recovery — at a 3% net margin, every $1 of incident cost requires about $33 of new sales to offset.
