Enter the waste diverted and the total waste into the Calculator. The calculator will evaluate the Waste Index. 

Waste Index Formula

WI = WD / TW * 100

Variables:

  • WI is the Waste Index (%)
  • WD is the waste diverted
  • TW is the total waste

To calculate Waste Index, divide the waste diverted by the total waste, then multiply by 100.

How to Calculate Waste Index?

The following steps outline how to calculate the Waste Index.

  1. First, determine the waste diverted. 
  2. Next, determine the total waste. 
  3. Next, gather the formula from above = WI = WD / TW * 100.
  4. Finally, calculate the Waste Index.
  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.

waste diverted = 40

total waste = 50
