OEE Calculator — Overall Equipment Effectiveness

Enter your production data to calculate OEE — the gold-standard metric for measuring manufacturing performance. World-class benchmarks built in.

Production data

Planned production time

Total scheduled run time for the period (minutes).

min

Total downtime

All unplanned stops and changeover time (minutes).

min

Ideal cycle time

Theoretical minimum time to produce one unit (minutes).

min

Total units produced

All units produced including rejects.

units

Good units (first-pass)

Units that passed quality checks without rework.

Typical — room to improve

Availability

90.6%

World-class ≥ 85%

Performance

World-class ≥ 85%

OEE = 90.6% × 89.7% × 95.1% = 77.3%

Availability

How much of planned production time was the equipment actually running? Every unplanned stop and changeover that runs long reduces this.

Run time ÷ Planned time × 100

Performance

When running, how fast is it going vs. its theoretical max? Micro-stops and slow cycles drag this down without triggering a "downtime" event.

(Total count × Ideal cycle time) ÷ Run time × 100

Quality

Of everything produced, how much was good on the first pass? Rework and scrap both count as quality losses.

Good count ÷ Total count × 100

OEE benchmarks by industry

World-class OEE is widely cited at 85%. Most plants land between 40–60% when they measure honestly for the first time.

Discrete manufacturing

Typical: 55–65%

World-class: 85%

Process manufacturing

Typical: 65–75%

World-class: 85%

Food & beverage

Typical: 50–60%

World-class: 85%

Pharmaceuticals

Typical: 70–80%

World-class: 90%
