Machine downtime logLog every stop on one machine for one shift, with its reason, so availability rests on recorded minutes.OEE Tracking Sheet (Overall Equipment Effectiveness)
Define the production window and planned exclusions before collecting data.
What it's for
Use this OEE tracking sheet (overall equipment effectiveness) to keep the working record, its evidence and follow-up together. Define the production window and planned exclusions before collecting data. Use minutes for durations, seconds per piece for ideal cycle time and consistent total/good counts.
Recording individual stops
This sheet totals losses for the period. To see which stops drive availability loss, record each one with its start, end, duration and reason on a machine downtime log, then carry the total minutes into the availability calculation here. Rank repeat reasons on a Pareto chart, and check your availability, performance, quality and overall OEE figures with the free OEE calculator.

Completed manufacturing example
A 450-minute planned production period contains 50 minutes of availability loss. At a 30-second ideal cycle, 720 total pieces and 700 first-pass good pieces give OEE of 77.78%.
Availability = 400/450 = 88.89%; performance = 720/800 = 90%; quality = 700/720 = 97.22%. OEE = 700 x 30 / (450 x 60) = 77.78%. The target gap is -2.22 percentage points.
When to use this template
Keep setup loss inside the agreed production window; do not remove losses just to raise OEE. Zero denominators mean no valid result. First-pass rejects include rework and must not be subtracted twice.

How to use it
- Define the production window and planned exclusions before collecting data. Use minutes for durations, seconds per piece for ideal cycle time and consistent total/good counts.
- Calculate availability as operating/planned time, performance as ideal time for total output/operating time, and quality as first-pass good/total pieces. Multiply the decimal factors and convert to percent.
- Reconcile stoppages and equivalent losses without counting the same loss twice. Compare like-for-like periods and assign actions against the measured loss, not an assumed universal target.

Questions, answered.
01
How do you calculate OEE?
OEE is availability multiplied by performance multiplied by quality. Availability is operating time divided by planned production time, performance is ideal cycle time times total count divided by operating time, and quality is good count divided by total count. The worked example gives 88.89% x 90% x 97.22% = 77.78%.
02
What is a good OEE score?
85% is commonly cited as world-class OEE for discrete manufacturing, but it is a benchmark, not a rule, and many plants measure well below it when they start. Compare each line with its own baseline using the same definitions, and work on the largest measured loss first.
03
What is the difference between OEE and downtime tracking?
Downtime tracking records each stop, its duration and its reason. OEE combines those availability losses with speed and quality losses in one percentage, so a machine downtime log feeds the availability part of this sheet.
