Calculate your OEE — and see where it leaks.

Two calculators on one page. The classic method needs an ideal cycle time. The MachineWise method needs only what a machine can actually tell you — and works when batches are short, mixed, or long-cycle.

Method 1 · Classic OEE

The textbook calculation.

Availability × Performance × Quality, where performance is measured against an ideal cycle time. This is the definition behind the widely quoted 85% world-class benchmark.

One shift, one machine

USE YESTERDAY'S NUMBERS IF YOU HAVE THEM
Ideal cycle time is the fastest the machine has ever demonstrably run that part — not the quoted rate, and not the average.

A × P × Q
Availability loss — stops
Performance loss — slow cycles
Quality loss — rejects
Total lost value

Method: Availability = run time ÷ planned production time. Performance = (total parts × ideal cycle) ÷ run time. Quality = good parts ÷ total parts. Losses are converted at your machine hourly rate. This is one machine on one shift — MachineWise computes the same three factors continuously across every machine on your floor, with each stop already attributed to a reason.

Method 2 · MachineWise OEE

The calculation a machine can actually answer.

No ideal cycle time. No standards to maintain. Every input here is something MachineWise measures directly from the machine — which is why it survives short batches, mixed part numbers and long-cycle work that break the textbook method.

Measured inputs

EVERY FIELD BELOW IS READ FROM THE MACHINE
Reporting time = — breaks are removed here, so they never count as a loss.
MACHINEWISE OEE

Quality
approved ÷ produced
A × P × Q
Availability loss — machine not powered on
Performance loss — on, but not in cut
Quality loss — time spent on rejects
Fully productive time

Reporting time = gross period − known breaks. Availability = machine on-time ÷ reporting time. Performance = productive (in-cut) time ÷ machine on-time. Quality = approved parts ÷ parts produced. The three losses plus fully productive time always add back to the reporting time exactly — no unattributed remainder.

Which one should you use

Same three factors. Different question.

USE CLASSIC WHEN

You run long, stable batches of one part

High volume, a well-maintained standard cycle time, and a genuine need to compare against the 85% world-class benchmark or a customer's OEE clause. Classic performance catches a machine running below its rated speed — the MachineWise method will not.

USE MACHINEWISE WHEN

Your floor is job-shop reality

Short batches, many part numbers in one shift, long-cycle work, or standards that were last updated years ago. It needs no ideal cycle time, so it cannot be gamed by an optimistic standard — and it works from day one, on every machine, without setup.

READ BOTH

They answer different questions

Classic asks how fast. MachineWise asks how much of the paid-for time actually made parts. A machine can score 100% MachineWise performance while cutting slowly — which is exactly why the two numbers are worth seeing side by side.

HONEST COMPARISON

What each loss actually means

Availability lossMachine scheduled but stopped — breakdowns, changeovers, waitingMachine not powered on during reporting time
Performance lossRunning slower than the ideal cycle timePowered on but not in cut — setup, idling, waiting, operator absence

Needs a standard?Yes — an ideal cycle time per partNo — everything is measured
Comparable to “85% world class”?YesNo — treat it as your own baseline and improve against it
We publish both because pretending one number fits every floor is how OEE lost its credibility in the first place. When citing either figure externally — to a customer or an auditor — state which definition you used.
