What counts as robot runtime?

Time the controller spends executing the program, from the controller log or a time study. Powered-on hours, waiting for parts and waiting on a machine do not count, or utilization looks better than the cell really is.

What utilization target should a robot cell set?

One your maintenance and changeover history can support. A target near the top of the range leaves no room for planned service or recovery. Set the target from your own logged stops, not a published benchmark.

Do planned stops belong in scheduled cell hours?

Yes, if the cell is scheduled to be available then. Keeping planned maintenance inside scheduled time makes the loss visible; if you remove it, compare the result with targets built the same way.

How do I close a utilization gap?

Start with the losses you can name: blocked time from downstream machines and starved time from upstream supply, both covered by Robot Idle Time. Only after those are small does a second robot or shift make sense.

Robotics & Automation calculator

Robot Utilization Calculator

Measure how much of the scheduled cell time a robot actually runs, then compare that utilization with the target you set. The gap and the unused hours show how much room a recovery plan has.

What this calculator does

Share of scheduled cell time the robot actually runs, the gap to your target, and the scheduled hours still unused.

Formula used

Utilization (%) = robot runtime hours ÷ scheduled cell hours × 100
Gap to target (points) = target utilization − utilization
Unused scheduled time (hr) = MAX(scheduled cell hours − robot runtime hours, 0)

Inputs explained

Robot Runtime: Hours the robot spent executing its program in the period.
Scheduled Cell Hours: Hours the cell was scheduled and staffed to run.
Target Utilization: Your utilization target for this cell, from site standards.

How to use the result

Best suited to comparing shifts on one robot cell, building a case for a second robot, tracking a cell against its utilization target.
Utilization says nothing about part quality or cycle pace; a busy cell can still make scrap. Scheduled hours include planned stops, so a generous schedule lowers the percentage.

Current U.S. benchmarks

As of Aug 2026, U.S. manufacturing runs at 75.7% of capacity (Federal Reserve via FRED), down 0.1 points from a year earlier. Enter your own plant's utilization; the national figure is a reference point for how loaded the industry is.
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.
