OEE calculator
What would higher OEE add to your margin?
OEE is availability × performance × quality. When OEE rises, good output rises with it. The calculator values that extra output at a 25% contribution margin.
$
Sales value of the output from the lines in scope. If you cannot sell more output, enter only the share you could sell.
%
Availability × performance × quality. If you have not measured it, about 50% is a cautious start.
%
Benchmark is 60%.
What holds back OEE
Where equipment time gets lost.
Each one takes hours of good output from a line that is already paid for.
Reactive maintenance
Crews working on what broke today instead of what is due.
Measure: Preventive vs. Reactive Maintenance Ratio; PM Compliance Rate (%)Repair time
Repairs that take longer because history and procedures are missing.
Measure: MTTR using Corrective MaintenanceDelayed work orders
Work orders that slip past their due date, often waiting on parts or people.
Measure: Maintenance WO Delayed DaysAbout the calculator
Straight answers.
The calculator sizes a possibility. Your Oracle Fusion data is what turns it into a number you can act on.
Request a Value DiscoveryWhich part of OEE does maintenance change?
Mostly availability: fewer breakdowns and shorter repairs. Planned maintenance also reduces minor stops, which lifts performance. Quality moves less directly.
What if we can't sell more output?
Enter only the share of production value you could sell. If that is none, the value shows up as fewer shifts, less overtime or deferred capital spend instead.
We don't measure OEE today. Can we still use this?
Yes. Use a cautious estimate; around 50% is a common starting point. A Value Discovery can build an OEE baseline from your work order and downtime records.
How accurate is the calculator?
It is only as accurate as the assumptions you enter. It is designed to size a possibility, not to produce an auditable number. A Value Discovery replaces your assumptions with evidence from your own Oracle data.
