Overall Equipment Effectiveness (OEE) Calculator
Calculate availability, performance, quality and OEE without hiding diagnostic values above 100%.
This tool provides a preliminary engineering calculation for reference. Final equipment selection, design and commissioning decisions must consider manufacturer data, applicable standards, operating conditions and project-specific engineering requirements. It is not certified design output.

Enter values and select Calculate. Results are estimates and do not replace nameplate data, applicable standards, or an engineering review.
Use this calculation
Only calculator parameters and results are transferred. Personal details are collected separately in the destination form.
Formula
A = Runtime/Planned Production Time
P = Ideal Cycle Time × Total Count/Runtime
Q = Good Count/Total Count
OEE = A × P × Q
Worked example
480 planned minutes, 60 downtime, 0.5 min ideal cycle, 700 total and 665 good.
Expected check: Availability = 87.5; Performance = 83.33; Quality = 95; OEE = 69.27.
Assumptions
- • Planned time, downtime, cycle time and count boundaries are aligned
Limitations
- • Does not define the plant's loss taxonomy or data-quality rules
- • OEE comparisons require consistent boundaries and ideal-rate definitions
Frequently asked questions
Can this result be used for final equipment selection?
No. Use it for a preliminary check, then verify manufacturer data, site conditions, applicable standards and the complete system design.
What does formula version 1.0.0 mean?
It identifies the exact calculation logic used so a saved result can be traced when the formula register changes.
Can Elexorn review my calculation?
Yes. Transfer the result to Request a Quote or Talk to an Elexorn Engineer and add the relevant project or equipment details.
