Calculator Inputs
Enter all stage durations using one common input unit. The calculator converts totals into your chosen output unit and estimates pace, efficiency, delays, yield, and business-day impact.
Example Data Table
This example matches the default values loaded into the calculator.
| Scenario | Setup | Processing | Inspection | Move | Queue | Wait | Batch | Completed | Total Throughput |
|---|---|---|---|---|---|---|---|---|---|
| Order Batch A | 0.50 h | 5.00 h | 0.50 h | 0.25 h | 1.50 h | 0.50 h | 100 | 96 | 8.25 h |
| Order Batch B | 0.75 h | 6.25 h | 0.40 h | 0.35 h | 2.00 h | 0.80 h | 120 | 114 | 10.55 h |
| Order Batch C | 0.30 h | 3.80 h | 0.25 h | 0.20 h | 1.10 h | 0.30 h | 80 | 78 | 5.95 h |
Formula Used
- Throughput Time = Setup Time + Processing Time + Inspection Time + Move Time + Queue Time + Wait Time
- Cycle Time Per Completed Unit = Throughput Time ÷ Completed Units
- Throughput Rate = Completed Units ÷ Total Throughput Time
- Flow Efficiency = (Processing Time ÷ Throughput Time) × 100
- Non Value Added Time = Throughput Time − Processing Time
- Queue + Wait Share = ((Queue Time + Wait Time) ÷ Throughput Time) × 100
- Batch Yield = (Completed Units ÷ Batch Size) × 100
- Estimated Business Days = Total Minutes ÷ (Working Hours Per Day × 60)

FAQs
1) What is throughput time?
Throughput time is the full elapsed time required for work to move through a process. It includes active work and delays such as queue, move, inspection, setup, and waiting. It shows how long completion actually takes from start to finish.
2) How is throughput time different from cycle time?
Throughput time measures the entire process duration. Cycle time usually describes the average time needed to finish one unit. In this calculator, cycle time per completed unit is estimated by dividing total throughput time by completed units.
3) Why are queue and wait time important?
Queue and wait time often reveal hidden delays. A process can look efficient during active work but still finish slowly because jobs sit idle between stages. Tracking both values helps teams identify where flow is being interrupted.
4) What does flow efficiency mean?
Flow efficiency is the share of total throughput time spent on true processing work. Higher percentages mean more of the total elapsed time is productive. Lower percentages suggest delays or support activities are dominating the process.
5) Can I use minutes, hours, or days?
Yes. Enter all stage durations in one input unit, then choose any display unit you prefer. The calculator converts the total and all related metrics automatically, which is useful when comparing short jobs and long schedules.
6) What is non value added time?
Non value added time is everything in the total throughput time except actual processing time. It often includes setup, inspection, move, queue, and wait time. Reducing this value can improve completion speed without increasing workload pressure.
7) Why does the calculator ask for completed units?
Completed units are used to estimate cycle time per completed unit, throughput rate, and yield. This makes the tool more practical for real operations where the full batch may not finish or some units may be delayed or rejected.
8) When should I export CSV or PDF results?
Use CSV when you need further analysis in spreadsheets or dashboards. Use PDF when you want a shareable snapshot for meetings, audits, status updates, or printing. Both options help document process performance clearly and consistently.
