Enter the total depth (in) and the number of passes into the Calculator. The calculator will evaluate the Depth Per Pass. 

Depth Per Pass Formula

DPP = TD / P


  • DPP is the Depth Per Pass (depth/pass)
  • TD is the total depth (in)
  • P is the number of passes

To calculate Depth Per Pass, divide the total depth by the number of passes.

How to Calculate Depth Per Pass?

The following steps outline how to calculate the Depth Per Pass.

  1. First, determine the total depth (in). 
  2. Next, determine the number of passes. 
  3. Next, gather the formula from above = DPP = TD / P.
  4. Finally, calculate the Depth Per Pass.
  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 depth (in) = 2.5

number of passes = 10
