Enter the initial dimension before drawing (in) and the final dimension after drawing (in) into the Draw Reduction Calculator. The calculator will evaluate the Draw Reduction.

## Draw Reduction Formula

The following two example problems outline the steps and information needed to calculate the Draw Reduction.

DR = (I – F) / I * 100

Variables:

• DR is the Draw Reduction (%)
• I is the initial dimension before drawing (in)
• F is the final dimension after drawing (in)

## How to Calculate Draw Reduction?

The following steps outline how to calculate the Draw Reduction.

1. First, determine the initial dimension before drawing (in).
2. Next, determine the final dimension after drawing (in).
3. Next, gather the formula from above = DR = (I – F) / I * 100.
4. Finally, calculate the Draw Reduction.
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.

initial dimension before drawing (in) = 5

final dimension after drawing (in) = 3.25

DR = (I – F) / I * 100 = ?
