Use this continuous process oee calculator to turn shop-floor records into a decision-ready operating measure. Enter the production window, output, loss, or demand values that match the continuous process being reviewed. The calculator returns the main result together with supporting rates or loss components, so you can trace what drives the number. It is designed for quick planning and performance checks without assuming an industry benchmark that may not fit your equipment, product mix, or inspection policy.
OEE = Availability × Performance × Quality, where Availability = run time ÷ planned time, Performance = (ideal cycle time × total count) ÷ run time, and Quality = good count ÷ total count.
All time and output values must refer to the same measurement boundary.
OEE combines time loss, speed loss, and quality loss into one percentage. Its three components show where the measured loss occurred.
Use an attainable ideal cycle time for the same product and equipment. Performance is capped at 100% for display because values above 100% usually signal an input or standard-time mismatch.
For 1,440 planned minutes, 90 downtime minutes, a 0.05-minute ideal cycle, 25,000 total units, and 24,250 good units: availability is 93.75%, performance 92.59%, quality 97.00%, and OEE 84.20%.
Use one consistent period for every time and output input, such as a shift, production order, or full day.
Use an attainable ideal cycle time for the same product and equipment. Performance is capped at 100% for display because values above 100% usually signal an input or standard-time mismatch.
Compare them only when the input definitions and ideal standards are equivalent; otherwise calculate each product or product family separately.
Reports may use scheduled time, run time, gross output, or good output differently. Match those definitions before comparing values.
Count output according to the labels in the calculator and keep recovered, rejected, and good units separate where those fields are provided.
| Input | Use |
|---|---|
| Planned production time (minutes) | Enter the value measured for the same production window. |
| Downtime (minutes) | Enter the value measured for the same production window. |
| Ideal cycle time (min/unit) | Enter the value measured for the same production window. |
| Total units produced (units) | Enter the value measured for the same production window. |
| Good units produced (units) | Enter the value measured for the same production window. |
