Enter the reflected value and the original or incident value into the Calculator. The calculator will evaluate the Percent Reflection. 

Percent Reflection Formula

PRF = RV / OV * 100


  • PRF is the Percent Reflection (%)
  • RV is the reflected value
  • OV is the original or incident value

To calculate Percent Reflection, divide the reflected value by the incident value, then multiply by 100.

How to Calculate Percent Reflection?

The following steps outline how to calculate the Percent Reflection.

  1. First, determine the reflected value. 
  2. Next, determine the original or incident value. 
  3. Next, gather the formula from above = PRF = RV / OV * 100.
  4. Finally, calculate the Percent Reflection.
  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.

reflected value = 56

original or incident value = 80
