Overall Equipment Effectiveness is the gold standard metric for manufacturing performance. Here's how to calculate it, what your score actually means, and how to improve it.
OEE (Overall Equipment Effectiveness) is a manufacturing KPI that measures how effectively a machine or production line is being used compared to its full potential.
The formula is: OEE = Availability × Performance × Quality
A score of 85%+ is considered world class. Most plants sit between 40–60% — which means significant untapped capacity is hiding in your process.
Calculate Your OEE Now →OEE was designed around the Six Big Losses framework — the six categories of waste that erode equipment effectiveness:
Knowing which of the six is dragging your OEE down tells you exactly where to focus your improvement effort.
