The BLS reported a private-industry TRIR of about 2.4 for recent years; construction and manufacturing run higher. Many clients require contractors to have a TRIR below a set threshold.
How to use the TRIR Calculator – Total Recordable Incident Rate
- Number of OSHA recordable cases

- Total hours worked
Results update as you type, and every field accepts the units shown in its menu.
How it works
Enter recordable cases, DART cases, lost-time cases and total hours worked.
Tips
- Enter figures for the same period and in the same currency.
- Exchange rates and prices change constantly – update them before you rely on a result.
- Use results as estimates and confirm important figures with the official source.
- Everything runs in your browser – try different values to compare scenarios.
Common mistakes to avoid
- Mixing gross and net figures.
- Using outdated rates.
- Treating rules of thumb as exact.
Inputs explained
| Field | What to enter |
|---|---|
| Number of OSHA recordable cases | A number |
| DART cases | A number |
| Lost-time cases | A number |
| Total hours worked | A number |
What each result means
- Total recordable incident rate (TRIR) = [Number of OSHA recordable cases]×200000÷[Total hours worked]
- DART rate = [DART cases]×200000÷[Total hours worked]
- Lost time incident rate = [Lost-time cases]×200000÷[Total hours worked]
Example values
How the main result changes when Number of OSHA recordable cases changes and everything else stays at the example values above:
| Number of OSHA recordable cases | Total recordable incident rate (TRIR) |
|---|---|
| 3 | 1.25 |
| 4.5 | 1.88 |
| 6 | 2.5 |
| 7.5 | 3.13 |
| 9 | 3.75 |
| 12 | 5 |
Formula
TRIR = recordable cases × 200,000 ÷ total hours workedDART = DART cases × 200,000 ÷ hoursLTIR = lost-time cases × 200,000 ÷ hoursWorked example
Inputs — Number of OSHA recordable cases: 6; DART cases: 3; Lost-time cases: 2; Total hours worked: 480,000.
Results — Total recordable incident rate (TRIR) = 2.5; DART rate = 1.25; Lost time incident rate = 0.83.
