How to calculate changeover time percentage
Changeover time percentage measures what share of scheduled production time is spent switching between product runs rather than producing — a lean manufacturing efficiency metric.
How the calculation works
Changeover percentage = (Changeover time ÷ Scheduled production time) × 100.
Example
45 minutes of changeover in a 480-minute shift: (45÷480)×100 ≈ 9.4%.

Pro Tips for Changeover Time Percentage
- Reducing changeover time (often through SMED-style quick-changeover techniques) directly increases available production time without adding equipment.
- Track this by product/equipment combination to identify which changeovers are the biggest time sinks.
Common Changeover Time Percentage Mistakes to Avoid
- Treating all changeovers as equally impactful without identifying which specific product transitions take the longest.
