OEE Calculator
Calculate Overall Equipment Effectiveness (OEE) — the gold standard for measuring manufacturing productivity. Get Availability, Performance, and Quality scores with Six Big Losses breakdown.
OEE = Availability × Performance × Quality. World class: ≥85%. Typical: 60–75%.
Six Big Losses
Frequently Asked Questions
World class OEE is considered 85% or higher. A score of 60–75% is typical for manufacturing companies. Below 60% generally indicates significant improvement opportunities. Scores above 90% are rare and require exceptional process control.
OEE = Availability × Performance × Quality. Availability = Actual Run Time ÷ Planned Production Time. Performance = (Ideal Cycle Time × Total Parts) ÷ (Actual Run Time × 3600). Quality = Good Parts ÷ Total Parts.
OEE measures efficiency relative to planned production time. TEEP (Total Effective Equipment Performance) measures efficiency relative to all calendar time (24/7/365). TEEP = OEE × (Planned Time ÷ Calendar Time).
Identify your lowest scoring factor first. For low Availability: implement preventive maintenance and SMED. For low Performance: analyze minor stops and speed losses. For low Quality: root cause defects and improve process controls.
