How to calculate manufacturing lead time
This calculator finds total manufacturing lead time by adding queue time and processing time.
How the calculation works
Lead time = Queue time + Processing time.
Example
3 days queue time plus 2 days processing: 3+2 = 5 days total lead time.

Pro Tips for Manufacturing Lead Time
- Queue time (waiting to be worked on) often makes up a larger share of total lead time than actual processing in many manufacturing environments — worth investigating separately.
- Reducing queue time (through better scheduling) can sometimes have more impact than speeding up actual processing.
Common Manufacturing Lead Time Mistakes to Avoid
- Focusing improvement efforts only on processing time while ignoring queue time, which is often the larger contributor to total lead time.
