How to calculate
Combine one setup and sequential unit processing into batch time and effective throughput.
Total batch time =
setup+units*cycle/60 minEffective batch throughput =
units/((setup+units*cycle/60)/60) units/hSetup share of batch time =
setup/(setup+units*cycle/60)*100 %Worked example
- Units in batch: 120
- Cycle time per unit (s): 30
- Setup time per batch (min): 20
- Total batch time: 80 min
- Effective batch throughput: 90 units/h
- Setup share of batch time: 25 %
Assumptions and limits
Assumes one sequential process, fixed cycle time, one setup and no overlap. Queues, breaks, scrap, downtime and parallel machines are excluded.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Combine one setup and sequential unit processing into batch time and effective throughput. A larger batch spreads the same setup over more units, but does not automatically improve flow time or inventory performance.
When this tool is useful
A larger batch spreads the same setup over more units, but does not automatically improve flow time or inventory performance.

Frequently asked questions
What assumptions should I check?
Assumes one sequential process, fixed cycle time, one setup and no overlap. Queues, breaks, scrap, downtime and parallel machines are excluded.
How can I check the result?
Start with the labelled example. Keep units consistent, calculate without intermediate rounding and change one input at a time. The diagram explains the model; the result table supplies the numerical answer.
