Free tool · OEE and the value of an hour
What could an hour of stopped line be worth?
Estimate what an hour of net production is worth on your line, from your own sales value per unit. Then work out OEE from one shift's numbers. The platform shows the hours; the rand figure is your own estimate.
Your result
This is your own estimate, not a cost or a saving. It covers only the downtime your log records: interruptions under your stop threshold are usually missing.
Your result
OEE is measured from planned production time. The last line starts from paid time instead, so breaks, cleaning and waiting count too. What OEE means, and what it hides ›
Where the time went
Of 450 planned production minutes, 328 produced good units at ideal speed. The rest is split below by who the time sits with.
| Who it sits with | What it covers | Minutes | Share |
|---|---|---|---|
| Fully productive | Good units at ideal speed | 328.1 | 72.9% |
| Operator | Changeover and cleaning overrun, waits with no call, the interruptions traced to them, speed loss from pace | 55.5 | 12.3% |
| Technician | Breakdowns and faults from the call, speed loss from a mechanical limit | 20.0 | 4.4% |
| Quality loss | Units that failed quality, at ideal speed; reported by job and product | 36.5 | 8.1% |
Estimate from your inputs. The example figures shown first are illustrative. Formulas: How to calculate OEE. Owner rule: OEE+ and the Owner column, Augos Factory method. Planned stops sit outside planned production time and are not in OEE; Augos measures them separately as Planning Efficiency Loss.
Simplified. On the platform the owner follows the part of the stop, not the reason: OEE+ and the Owner column.

How does the calculator work out OEE?
It uses the standard formula. Availability is run time divided by planned production time. Performance is the units produced divided by what the ideal rate would have produced in that run time. Quality is good units divided by total units. OEE is the product of the three. Every step is on How to calculate OEE.
What is the Owner split?
An estimate of who can recover each lost minute, following the OEE+ owner rule. Breakdowns go to the technician who takes the call; changeover and cleaning overrun, waits with no call and interruptions to the operator logged in; quality loss is reported on its own. It is calculated from the figures you enter, not from measured data.
Why are planned stops not counted against OEE?
Because the operator is not penalised for following the schedule. Planned stops sit outside planned production time by definition. Augos still measures them, as Planning Efficiency Loss, because the time scheduled is a loss someone owns. The overrun beyond the standard is a loss the operator owns.
Why does Performance change when I add downtime in counts mode?
Because Performance is units produced per running minute against the ideal rate. If the shift's total count stays the same while run time shrinks, the line must have produced those units faster, so Performance rises. That is the standard formula at work. Use the average-speed mode to vary the three factors independently.
Is the calculator free?
Yes. Nothing you enter is sent anywhere; the arithmetic runs in your browser. The worksheet download is free too.
