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)

To calculate the draw reduction, divide the difference in dimensions by the initial dimension, then multiply by 100.

## How to Calculate Draw Reduction?

The following steps outline how to calculate the Draw Reduction.

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