## 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:

- First, determine the total weight of scrap.
- The total weight of scrap is given as: 300.

- Next, determine the total weight of material.
- The total weight of material is provided as: 600.

- 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

Test your knowledge using the equation and check your answer with the calculator..

SCRAP = WS / WM * 100** = ?**
