Track value added minutes across process steps with instant ratios. Reveal hidden waste fast clearly. Turn raw cycle data into practical productivity improvements today.
Enter shift settings first, then add time values for each process step. Use minutes per unit for consistent results.
| Step | Value-Added (min) | Support (min) | Waste (min) | Total (min) |
|---|---|---|---|---|
| Order Review | 6.00 | 2.00 | 1.00 | 9.00 |
| Data Entry | 10.00 | 3.00 | 2.00 | 15.00 |
| Approval | 4.00 | 2.00 | 6.00 | 12.00 |
| Packaging | 8.00 | 1.00 | 1.00 | 10.00 |
| Totals | 28.00 | 8.00 | 10.00 | 46.00 |
In this example, the value-added ratio is 60.87%, calculated as 28.00 ÷ 46.00 × 100.
Value-added time is the portion of work that directly changes the product or service in a way the customer is willing to pay for.
Lead time includes every minute from start to finish. Value-added time includes only the productive minutes that create customer-recognized output.
Support time may be necessary for control or compliance. Waste time adds no value and should be reduced first, which makes improvement priorities clearer.
The answer depends on the process. Many administrative workflows are low, while optimized production cells can be much higher. Trends matter more than a single benchmark.
Yes. Use any single unit consistently across every input. The calculator will remain correct as long as all step times use the same unit.
Takt time needs both available time and demand. If you only want flow efficiency, you can skip those fields and still calculate value-added ratios.
It estimates how much non-value-added time must be removed to achieve your target efficiency, assuming productive time stays constant.
Reduce waiting, approvals, rework, searching, and extra movement first. Then standardize work, improve handoffs, and simplify controls that create support time.
