Enter the machine availability, the performance factor, and the quality rate into the OPE Calculator. The calculator will evaluate the OPE.

## OPE Formula

The following formula is used to calculate the OPE.

**OPE = A * PF * QR**

Variables:

- OPE is the OPE ( )
- A is the machine availability
- PF is the performance factor
- QR is the quality rate

## How to Calculate OPE?

The following steps outline how to calculate the OPE.

- First, determine the machine availability.
- Next, determine the performance factor.
- Next, determine the quality rate.
- Next, gather the formula from above = OPE = A * PF * QR.
- Finally, calculate the OPE.
- 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.

machine availability = .75

performance factor = 1.2

quality rate = 30

OPE = A * PF * QR =** ** ?
