ClarityHow to use this tool
- Enter planned production time, stop time, ideal cycle time, total units produced, good units.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Run time = planned time − stops. Availability = run/planned; performance = ideal cycle × total/run; quality = good/total. OEE is their product.
Using planned production time = 480 min, stop time = 60 min, ideal cycle time = 0.5 min/unit, total units produced = 700, good units = 665, the result is 69.2708333 %. Change these example inputs to match your task; use the method above to check each step.
Understanding your result
An ideal cycle should represent the fastest valid production speed. A higher calculated speed indicates mismatched units, counts or an unsuitable ideal cycle.
What to keep in mind
One production period and a consistent ideal cycle time are required. Mixed products need a suitable weighted model. Use consistent currencies, reporting periods and accounting definitions. This arithmetic estimate excludes items not entered in the form.

Common questions
Why is performance above 100% rejected?
An ideal cycle should represent the fastest valid production speed. A higher calculated speed indicates mismatched units, counts or an unsuitable ideal cycle.
