Enter the total weight of the casting and the total weight of the metal poured into the calculator to determine the casting yield efficiency.

## Casting Yield Formula

The following equation is used to calculate the Casting Yield.

CY% = WC / WM * 100

• Where CY% is the casting yield efficiency (%)
• WC is the weight of the casting
• WM is the weight of the metal poured

To calculate the casting yield efficiency, divide the weight of the casting by the weight of the metal poured to create the casting, then multiply by 100.

## What is a Casting Yield?

Definition:

A casting yield, or sometimes referred to as casting efficiency, is a measure of the percentage of weight of metal that is poured comes out in the final product of the casting.

In other words, it measures how effectively a machine uses metal in it’s casting process.

## How to Calculate Casting Yield?

Example Problem:

The following example outlines the steps and information needed to calculate Casting Yield.

First, determine the weight of the metal poured. In this example, the weight of the metal poured is found to be 500 lbs.

Next, determine the weight of the casting once it is finished. In this case, the weight of the casting is measured to be 400 lbs.

Finally, calculate the casting yield efficiency using the formula above:

CY% = WC / WM * 100

CY% = 400 / 500 * 100

CY% = 80%
