Enter the total number of injuries over the time between 100 workers and the total hours worked into the Calculator. The calculator will evaluate the Medical Treatment Injury Frequency Rate. 

Medical Treatment Injury Frequency Rate Formula

MTI = I / HW  * 1,000,000

Variables:

  • MTI is the Medical Treatment Injury Frequency Rate (injuries per million hours)
  • I is the total number of injuries over the time between 100 workers
  • HW is the total hours worked

To calculate Medical Treatment Injury Frequency Rate, divide the number of injuries over the period between 100 works by the total hours worked, then multiply by 1,000,000.

How to Calculate Medical Treatment Injury Frequency Rate?

The following steps outline how to calculate the Medical Treatment Injury Frequency Rate.


  1. First, determine the total number of injuries over the time between 100 workers. 
  2. Next, determine the total hours worked. 
  3. Next, gather the formula from above = MTI = I / HW * 1,000,000.
  4. Finally, calculate the Medical Treatment Injury Frequency Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of injuries over the time between 100 workers = 500

total hours worked = 30,000
