How to Calculate OEE (Overall Equipment Effectiveness) Step-by-Step with Examples

OEE (Overall Equipment Effectiveness) is one of the most important metrics in manufacturing—but many teams struggle to calculate it accurately.

This guide breaks down exactly how to calculate OEE step-by-step.

What is OEE (Overall Equipment Effectiveness)?

OEE (Overall Equipment Effectiveness) measures how effectively equipment is being used by combining:

The formula is:

OEE = Availability × Performance × Quality

Step 1: Calculate Availability

Availability = Run Time / Planned Production Time

Example:
Planned Production Time = 8 hours
Downtime = 2 hours
Run Time = 6 hours

Availability = 75%

Step 2: Calculate Performance

Performance = (Ideal Cycle Time × Total Units) / Run Time

Example:
Ideal Cycle Time = 1 minute
Total Units = 300
Run Time = 360 minutes

Performance = 83%

Step 3: Calculate Quality

Quality = Good Units / Total Units

Example:
Total Units = 300
Good Units = 270

Quality = 90%

Final OEE Calculation

OEE = 75% × 83% × 90% = 56%
