Scrap Recovery OEE Calculator
Measure the overall equipment effectiveness of a scrap recovery line from availability, performance, and quality. The calculator combines scheduled time, downtime, actual output, ideal rate, and recovered material that meets specification so you can see which OEE factor is holding the operation back.
Calculator
Availability, speed, and qualityFormula
Availability = run time ÷ scheduled time. Performance = total output ÷ (run time × ideal rate). Quality = good output ÷ total output. OEE = availability × performance × quality.
What the result means
The main result describes the measured rate or loss for the entered operating period. Read it together with the supporting figures to avoid confusing speed, capacity, quality, and material efficiency.
This is an operational estimate. Validate input definitions against your plant records before using the result for staffing, costing, or capital decisions.
Example calculation
For 480 scheduled minutes, 45 minutes of downtime, a 2-unit/minute ideal rate, 780 total units, and 750 good units, OEE is 78.13%.
Tips for better results
- Use data from comparable jobs and operating conditions.
- Separate planned stops from unexpected delays.
- Keep good output and total output definitions consistent.
- Investigate the largest loss component first.
- Repeat the calculation over several periods before treating a change as a trend.
Frequently asked questions
Can I use partial production units in this calculator?
Yes. Decimal inputs are accepted where the measured quantity or time is not a whole number.
How should planned downtime be entered for scrap recovery?
Enter only the time excluded by the field label. Keep the measurement period consistent across all inputs.
Why can the result change when the same total output is used?
Time, usable output, demand, or quality inputs change the denominator or effective output, so the resulting rate changes.
Does this calculator set an industry target for scrap recovery?
No. Appropriate targets depend on equipment, material, product mix, and operating conditions.
Can I compare two scrap recovery periods?
Yes. Run each period separately with the same units and definitions, then compare the displayed primary and secondary results.
