Enter last year's hours and cases (straight off your OSHA 300 log) and get the rates prequalification forms want. Runs in your browser; nothing uploads.
No payroll totals? Employees × ~2,000 hours is a rough full-time-year estimate.
Formula: rate = (cases × 200,000) ÷ hours worked. 200,000 = 100 full-time workers' annual hours, so rates compare fairly across company sizes. GCs typically want TRIR & DART for the last 1–3 years; your EMR (experience modification rate) comes from your workers' comp insurer, not this math.
This calculator needs you to bring the numbers. The full SiteSafetyHQ product keeps the log itself — injuries reported from a phone, recordability answered with the rule cited, OSHA's actual forms filled, deadlines watched — so the case counts behind your rates are always current and defensible.
No card, no demo call. Flat $39–$199/mo by company size.
It varies by industry — compare against your industry's BLS average rather than a universal number. Many GCs flag subs above roughly 3.0, but their thresholds differ; ask the GC what they screen on. Current BLS benchmarks and a worked example: how to calculate TRIR.
TRIR counts all recordable cases. DART counts only the more serious subset (days away, restricted, or transferred). EMR is an insurance multiplier computed by your workers' comp carrier from claims history — related, but a different animal.
Straight off your OSHA 300A summary — totals G+H+I+J are your recordables; H and I feed DART. Build yours with the free 300 log tool.
