Enter the total weight of scrap and the total weight of material into the Scrap Rate Calculator. The calculator will evaluate the Scrap Rate.

## Scrap Rate Formula

The following two example problems outline the steps and information needed to calculate the Scrap Rate.

SCRAP = WS / WM * 100

• Where SCRAP is the Scrap Rate (%)
• WS is the total weight of scrap
• WM is the total weight of material

## How to Calculate Scrap Rate?

The following example problems outline how to calculate Scrap Rate.

Example Problem #1:

1. First, determine the total weight of scrap.
• The total weight of scrap is given as: 300.
2. Next, determine the total weight of material.
• The total weight of material is provided as: 600.
3. Finally, calculate the Scrap Rate using the equation above:

SCRAP = WS / WM * 100

The values provided above are inserted into the equation below and computed.

SCRAP = 300 / 600 * 100 = 50.00 (%)

Example Problem #2:

For this problem, the variables required are provided below:

total weight of scrap = 200

total weight of material = 1000
