What is a good OEE for a robot cell?

There is no universal number; track the trend and compare like cells. A robot that waits on a machine inherits that machine's losses, so read OEE beside the cell throughput figures.

Where do the three factors come from?

Availability is operating hours over planned hours. Performance compares ideal cycle time with measured cycle time. Quality is good parts over parts started. Each one comes from a different log.

Can OEE come out above availability?

Only if performance or quality passes 100%, which means an ideal cycle or a part count is wrong. Correct the record before you report the number.

Does a machine stop count against the robot?

If the robot waits while the machine is down, that time counts against robot availability. If the machine sits outside the robot's planned hours, it does not.

Robotics & Automation calculator

Robot OEE Calculator

Measure how much of the scheduled time the robot turns into good parts at the ideal rate. Enter operating and planned hours, then the performance and quality factors your logs report.

What this calculator does

Robot OEE as the product of availability, performance and quality, with the gap to the target you set.

Formula used

Base availability (%) = operating hours ÷ planned production hours × 100
OEE (%) = operating hours ÷ planned production hours × performance factor × quality factor ÷ 100
Performance factor (%) = ideal cycle time ÷ measured cycle time × 100
Quality factor (%) = good parts ÷ parts started × 100
Gap to target (points) = target OEE − OEE

Inputs explained

Operating Hours: Hours the robot ran productively, from the OEE log.
Planned Production Hours: Scheduled production hours with planned stops removed.
Performance Factor: Measured cycle rate against the ideal, from the program log.
Quality Factor: First-pass yield or accepted output, from inspection.
Target OEE: The OEE level your cell is expected to hold.

How to use the result

Best suited to weekly OEE reporting for a robot cell, comparing two shifts on the same line, building the case for a cell upgrade.
One performance and one quality value hide which shift or product lost output; split the log when you can. OEE sizes the loss but does not name its cause; match stops and rejects to a factor before acting. A stale ideal cycle inflates the performance share; audit the ideal against the work content.

Current U.S. benchmarks

Global copper trades at $13,543 per tonne (IMF via FRED, Jul 2026), up 38.6% in a year, and U.S. industrial electricity averages 9.77 cents per kWh. Both feed electrified-hardware unit economics.
