How is OEE calculated?

OEE is the product of three factors: Availability x Performance x Quality. Availability is run time divided by planned production time; performance is (ideal cycle time x total units) divided by run time; quality is good units divided by total units.

What is a good OEE score?

World-class OEE is about 85%. Many plants run closer to 60%, which leaves significant room to improve. An OEE below 60% usually points to meaningful losses in at least one of the three factors.

What do availability, performance, and quality represent?

Availability captures stop losses (breakdowns and unplanned stops). Performance captures speed losses (cycles slower than ideal, small stops). Quality captures defect losses (rejected parts and rework).

Does this tool track OEE over time?

No. This calculator gives OEE for a single shift from figures you enter. For continuous tracking per work center and period, Odoo Manufacturing (MRP) computes OEE from live production data. Octura sets that tracking up.

Planned production time (min) Shift length minus planned breaks

Downtime (min) Breakdowns and unplanned stops during the shift

Ideal cycle time (sec/unit) The fastest time to produce one unit

Total units produced All units, good and rejected

Good units Units that pass first time, no rework

OEE80.7%World-class OEE: about 85%

Availability90.2%

Performance92.4%

OEE = Availability x Performance x Quality. Availability is run time over planned time; performance compares actual output to the ideal cycle time; quality is the share of good units.

What OEE Is

Overall Equipment Effectiveness (OEE) measures how close a production asset runs to its full potential. It is the product of three factors: Availability x Performance x Quality. An OEE of 100% would mean producing only good parts, as fast as possible, with no stop time.

Availability is run time divided by planned production time, the share of the shift that was actually productive after breakdowns and unplanned stops. Performance compares actual output to what the ideal cycle time would have produced over that same run time. Quality is the share of units that were good first time out of all units produced.

Factor	Formula
Availability	Run time / Planned production time
Performance	(Ideal cycle time x Total units) / Run time
Quality	Good units / Total units
OEE	Availability x Performance x Quality

Run time equals planned production time minus downtime. Because OEE is a product, a single weak factor pulls the whole score down, which is exactly what makes it a useful diagnostic for where losses live.

Tracking OEE in Odoo Manufacturing (MRP)

A spreadsheet gives you OEE for one shift; Odoo Manufacturing (MRP) tracks it continuously. Manufacturing orders record produced and scrapped units, work centers capture cycle times and stoppages, and maintenance logs breakdowns. From that live data Odoo computes availability, performance, and quality per work center and per period, with no double entry.

Octura sets up work centers, loss reason codes, and dashboards so OEE becomes a routine measure rather than a quarterly exercise. The goal is to see where the losses go, week over week, and act on them.
