How to Use This Tool
Input the scheduled production time for your shift, including breaks and planned stops.
Enter unplanned downtime minutes from equipment failures, material shortages, and other stoppages.
Provide the theoretical maximum production rate (units per minute) when equipment is running.
Input the actual units produced during the shift to calculate performance and OEE proxy values.

Frequently Asked Questions
What is OEE and why is it important?
OEE (Overall Equipment Effectiveness) measures manufacturing productivity by combining availability, performance, and quality. This calculator focuses on availability and performance as a proxy, helping identify efficiency improvements.
How do I determine the ideal rate?
The ideal rate is the maximum theoretical production speed when equipment is running at full capacity. This should be based on equipment specifications, design capacity, or best observed performance without quality issues.
What counts as planned time vs. downtime?
Planned time includes scheduled production periods, while downtime includes unplanned stoppages like equipment failures, material shortages, operator absence, and other unexpected interruptions. Planned breaks are typically not counted as downtime.
Can this calculator handle multi-shift operations?
Yes, this calculator works for any time period. For multi-shift analysis, you can either calculate each shift separately or sum the values across shifts to get daily metrics, ensuring consistent time units.
What is a good OEE score?
World-class OEE is typically considered 85% or higher. Scores between 60-85% indicate typical performance with room for improvement, while below 60% suggests significant efficiency issues that should be addressed.
Why does this calculator use OEE proxy instead of full OEE?
This calculator focuses on availability and performance as they are the most easily measured from basic production data. Full OEE includes quality metrics which require additional data about defects and rework, making this a useful proxy for quick assessments.
