OEE Calculator
Measure your Overall Equipment Effectiveness, identify the Six Big Losses, and unlock actionable insights to maximize equipment productivity and reduce downtime.
The OEE Formula
OEE = Availability × Performance × Quality
World-Class OEE = 85% (90% Availability × 95% Performance × 99.9% Quality)
The Three Pillars of OEE
Understanding the components that drive equipment effectiveness
Availability
Measures the percentage of scheduled time that equipment is available for operation. Accounts for downtime from breakdowns, changeovers, and adjustments.
Target: 90%+
Performance
Compares actual output to maximum possible output. Identifies speed losses from slow cycles, minor stops, and idling equipment.
Target: 95%+
Quality
Percentage of good units produced vs. total units. Accounts for defects, rework, and startup rejects that waste production capacity.
Target: 99.9%+
Identify the Six Big Losses
Our calculator helps you pinpoint where your equipment is losing productivity
Equipment Failures
Unplanned downtime from breakdowns that stop production
Setup & Changeovers
Time lost during product changes and equipment adjustments
Minor Stops
Brief stoppages from jams, misfeeds, or sensor trips
Reduced Speed
Running slower than ideal cycle time due to wear or limitations
Process Defects
Quality losses during steady-state production
Startup Rejects
Defects during warmup, changeover, and ramp-up periods
