Introduction
The TRIR calculator helps you find your workplace's Total Recordable Incident Rate in seconds. TRIR is a number that shows how safe your workplace is. It counts work injuries and illnesses, then compares them to the total hours your team worked. A lower TRIR means fewer people got hurt on the job. OSHA uses this rate to measure safety across all types of businesses.
To use this calculator, you need three things: your total recordable cases, the number of days-away or restricted-work cases, and the total hours worked by all employees. Enter your numbers, click calculate, and the tool does the math for you. It uses the standard OSHA formula — recordable cases times 200,000 divided by total hours worked. You can also switch to a monthly mode if you only want to check one month at a time.
Once you get your result, the calculator compares your TRIR to industry benchmarks from the Bureau of Labor Statistics. You can filter by year, sector, and industry type to see how your rate stacks up. This makes it easy to spot whether your safety program is working well or needs attention.
How to Use Our TRIR Calculator
Enter your workplace safety numbers below to find your Total Recordable Incident Rate. The calculator will show your TRIR score, compare it to industry benchmarks, and give you a step-by-step breakdown of the math.
Calculation Period: Pick Annual if your data covers a full year, or Monthly if it covers just one month. This sets the right multiplier for your rate.
Total Recordable Cases: Enter the number of work-related injuries or illnesses that needed more than basic first aid. This includes cases with days away, restricted work, job transfers, or a diagnosis from a doctor.
Cases Involving Days Away from Work: Enter the number of recordable cases where the worker missed at least one day of work. This must be equal to or less than your total recordable cases. If you also track employee absence patterns, a Bradford Factor Calculator can help you measure the impact of short, frequent absences on your operations.
Cases Involving Job Transfer or Restricted Work Activity Only: Enter the number of recordable cases where the worker was moved to a different job or put on light duty but did not miss a full day of work.
Total Hours Worked by All Employees: Enter the total hours all your employees actually worked during the period. Do not count vacation, sick days, or other time off. For example, 50 employees working 2,000 hours each equals 100,000 total hours. If you need help tallying actual hours from timesheets, try our Work Hours Calculator or Time Card Calculator to get an accurate total.
Press Calculate TRIR to see your results. Use the Industry Benchmark Comparison panel to compare your rate against specific industries, sectors, years, or states.
What Is the Total Recordable Incident Rate (TRIR)?
The Total Recordable Incident Rate, or TRIR, is a number that shows how safe a workplace is. It counts how many work-related injuries and illnesses happened over a set number of hours worked. OSHA (the Occupational Safety and Health Administration) requires employers to track these incidents. TRIR is one of the most common ways to measure workplace safety performance in the United States. It often sits alongside other operational metrics like Overall Equipment Effectiveness (OEE) as a key indicator of how well a facility is managed.
How Is TRIR Calculated?
The TRIR formula is simple. You multiply your total recordable cases by 200,000, then divide by the total hours all employees worked. The number 200,000 stands for 100 full-time workers each putting in 2,000 hours per year. This standard multiplier lets you compare companies of different sizes on equal footing.
TRIR = (Total Recordable Cases × 200,000) ÷ Total Hours Worked
What Counts as a Recordable Case?
A recordable case is any work-related injury or illness that goes beyond basic first aid. This includes cases where a worker needed medical treatment, missed days of work, was moved to a different job, or had restricted duties. A doctor or licensed healthcare professional must diagnose or treat the condition for it to count. Minor injuries treated with a bandage or ice pack are not recordable.
What Is a Good TRIR?
A lower TRIR means a safer workplace. As of 2024, the average TRIR for all private industry in the U.S. is about 2.3, according to the Bureau of Labor Statistics. If your TRIR is below your industry average, your safety record is better than most. If it is above the average, there is room to improve. Different industries have very different averages. For example, oil and gas extraction averages around 0.5, while healthcare and transportation often exceed 3.5.
Why Does TRIR Matter?
Companies use TRIR to spot safety problems, set goals, and track progress over time. Using a Percent Change Calculator alongside your TRIR results can help you measure how much your incident rate improved or worsened from one period to the next. Many contractors must report their TRIR before they can bid on projects. Insurance companies also look at TRIR when setting premiums. A high TRIR can cost a business money and reputation. A low TRIR shows that a company takes worker safety seriously and has strong safety programs in place.
Annual vs. Monthly TRIR
Most companies calculate TRIR on a yearly basis using the 200,000-hour multiplier. However, you can also calculate a monthly rate by using 16,667 as the multiplier (200,000 divided by 12). Monthly tracking helps you catch trends early and respond to safety issues faster. Our Business Days Calculator can help you define the exact working period when gathering hours data for a specific month. This calculator supports both options.
