Machine Utilization Calculator

How it works

Utilisation is simply running time divided by the time the machine was available to run, for example the scheduled shift hours. It's the first number most factories get once they add a current clamp or spindle signal to a machine.

It differs from OEE: utilisation only asks 'was it running?', while OEE also asks whether it ran at full speed and made good parts. Use utilisation to find idle capacity and OEE to improve the running time you have.

Available hours = shift length × shifts per day × days
Utilisation = run hours / available hours
Gain at target = (target − current) × available hours

Worked example

A machine works two 8-hour shifts, 6 days a week: 96 available hours. Monitoring shows 61.5 hours of running, a utilisation of 64.1%. Raising it to 75% would free 10.5 more productive hours every week without buying another machine.
