Enter the total number of fractures and the total length (in) into the Calculator. The calculator will evaluate the Fracture Rate. 

Fracture Rate Formula



  • FRR is the Fracture Rate (fractures/in)
  • FRA is the total number of fractures
  • L is the total length (in)

To calculate Fracture Rate, divide the total number of fractures by the total length.

How to Calculate Fracture Rate?

The following steps outline how to calculate the Fracture Rate.

  1. First, determine the total number of fractures. 
  2. Next, determine the total length (in). 
  3. Next, gather the formula from above = FRR = FRA / L.
  4. Finally, calculate the Fracture 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 fractures = 9

total length (in) = 1.65
