OEE Lab / OEE Calculator

OEE Calculator

Enter your shift numbers and get Availability, Performance, Quality and OEE instantly - then see how you compare to world-class. Numbers update as you type.

Your shift

One machine or line, for one shift or day. Hover the hints if unsure.

min
Scheduled run time (e.g. 8 h = 480).
min
Breakdowns + changeovers + stops.
sec
Fastest the machine can make one good piece (nameplate speed).
What counts as each input?

Planned production time excludes scheduled non-production (no order, planned maintenance). Down time is every stop during planned time - including the short ones. Ideal cycle time is the theoretical fastest, not the average. Total pieces is everything produced (good + bad); reject is the bad ones (including rework).

Turn this one-off number into a live OEE trend.

The free OEE Tracker keeps every shift you log, builds your trend, benchmarks you against your industry and pinpoints your biggest loss. Two minutes, no PLC wiring, no account to start.

Your real OEE is probably lower than this.

This calculator only knows the stops you counted. The short micro-stops nobody logs can hide 10-18 OEE points. Fabrico reads OEE straight from the machine and shows the true cause - no manual logging.

How to calculate OEE

OEE = Availability × Performance × Quality. It's the single number for how much of your planned production time is truly productive - making good parts at full speed.

  • Availability = Run Time ÷ Planned Production Time. Run Time = Planned - all stops.
  • Performance = (Ideal Cycle Time × Total Count) ÷ Run Time. It captures speed loss and micro-stops.
  • Quality = Good Count ÷ Total Count.

What's a good OEE?

85% is world-class for discrete manufacturing (≈90% availability, 95% performance, 99.9% quality). 60% is typical - and very common. Below 40% means large, fast upside is available. One caveat: the 85% figure was set for high-volume lines running a single product, so a high-mix or changeover-heavy plant should track its own trend first rather than chase one number.

OEE benchmarks by industry

Benchmarks vary widely by process - compare like with like, and to your own trend first. Typical ranges:

IndustryTypical OEEWhy
Food & Beverage50-70%Changeovers, CIP, filler/capper micro-stops
Automotive65-85%Mature lines, but extreme cost per stop
Packaging & Converting45-65%Serial high-speed lines, heavy micro-stops
Plastics / Injection Moulding50-75%Cycle-time drift and long mould changeovers
World-class (any)85%+The universal aspirational benchmark

Ranges are industry estimates for orientation - see the sourced statistics and your industry guide.

Why is my measured OEE often higher than reality?

Because short stops under ~5 minutes rarely get logged, so their lost time never enters the math. That's the "hidden factory." Reading OEE automatically from the PLC closes the gap - size yours here.

Should performance ever be over 100%?

No - if it is, your ideal cycle time is set too slow or a count is off. We cap performance at 100% and flag it.

Is this the same as TEEP?

TEEP extends OEE by also counting unscheduled time (utilization). OEE measures planned time only; TEEP measures all calendar time.
