OEE Calculator
Calculate Overall Equipment Effectiveness (OEE) using Availability, Performance, and Quality.
Availability

Quality
Final OEE
The Math
OEE is the gold standard for measuring manufacturing productivity. It is calculated by multiplying three factors:
- Availability: Operating Time / Planned Production Time
- Performance: (Ideal Cycle Time × Total Count) / Operating Time
- Quality: Good Count / Total Count
OEE = Availability × Performance × Quality
Example Calculation
If you plan to run for 480 mins, but have 60 mins of downtime, your operating time is 420 mins. Availability is 420/480 = 87.5%.
If the ideal cycle time is 1.5 mins, and you made 250 parts, your net operating time is 375 mins. Performance is 375/420 = 89.2%.
If 240 of those parts are good, your Quality is 240/250 = 96.0%.
OEE = 87.5% × 89.2% × 96.0% = 74.9%
