Enter the current flow and the maximum flow into the Calculator. The calculator will evaluate the Flow Percent. 

Flow Percent Formula

FP = CF / MF *100


  • FP is the Flow Percent (%)
  • CF is the current flow
  • MF is the maximum flow

To calculate Flow Percent, divide the current flow by the maximum flow, then multiply by 100.

How to Calculate Flow Percent?

The following steps outline how to calculate the Flow Percent.

  1. First, determine the current flow. 
  2. Next, determine the maximum flow. 
  3. Next, gather the formula from above = FP = CF / MF *100.
  4. Finally, calculate the Flow Percent.
  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.

current flow = 100

maximum flow = 250
