Enter the error free products (units) and the total units into the Calculator. The calculator will evaluate the First Time Yield.

## First Time Yield Formula

FTY = EFP / TP * 100

Variables:

- FTY is the First Time Yield (%)
- EFP is the error free products (units)
- TP is the total units

To calculate First Time Yield, divide the number of error free products by the total units, then multiply by 100.

## How to Calculate First Time Yield?

The following steps outline how to calculate the First Time Yield.

- First, determine the error free products (units).
- Next, determine the total units.
- Next, gather the formula from above = FTY = EFP / TP * 100.
- Finally, calculate the First Time Yield.
- 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.

error free products (units) = 45

total units = 23
