Good to know
OEE
Overall equipment effectiveness: the share of planned time that makes good parts. Many plants run at 55% to 70%; world class is around 85%.
Raise OEE before buying
Cutting changeover time, breakdowns and rejects often adds more capacity than a new machine, for far less money.
Plan the bottleneck
Capacity is set by the slowest machine or line. Run this for the bottleneck step.
Leave headroom
Planning at 100% leaves no room for breakdowns or rush orders. Aim for 80% to 90% utilisation.
Questions people ask
Is it free? Do I need to sign up?
Yes, it is free and you do not need to sign up. Open it and use it as often as you like.
Is my data safe?
The numbers are worked out in your browser. Nothing you type is sent to USR unless you choose to email yourself the result.
How accurate is the result?
It is an estimate based on the rules shown on this page as of November 2026, not legal or tax advice. Rules and rates change, so check with your CA before you act.
What is OEE?
The share of planned time that makes good parts: availability × performance × quality.
I don't know my OEE.
Good parts made in a shift ÷ (shift minutes ÷ cycle minutes) gives a fair estimate.
Plan production on real capacity
USR Manufacturing plans orders against machine capacity, tracks OEE and rejects, and links to USR Quality for CAPA.
