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.

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