Manufacturing OEE Lost Capacity Cost Calculator
Turn Availability × Performance × Quality into lost productive hours, lost good-unit capacity, production-value opportunity and the capacity that could be recovered before adding equipment, shifts or outsourcing.

Compare cautiously
APQC's current public OEE benchmark page reports a 75.0% median across 3,100 companies. OEE is most useful for comparing a process with itself over time; product mix, planned-time rules, ideal-cycle definitions and data collection practices can materially change cross-company comparisons.

OEE is a loss-analysis framework, not just a score
NIST manufacturing publications describe OEE as Availability × Performance × Quality and as a measure of how much planned production time is truly productive. Vorne's OEE framework maps Availability to breakdowns/setup, Performance to small stops/reduced speed, and Quality to startup/reject losses. APQC's current public benchmark page reports a 75.0% median across 3,100 companies. Use benchmark data as directional context; the strongest use of OEE is finding and reducing losses on the same asset over time.

Capacity value is not automatically cash savings
Recovered OEE capacity creates economic value only when the business can sell the additional good output, avoid overtime or outsourcing, defer constrained-capacity spending, or otherwise monetize the capacity. Use the Demand Capture input to avoid valuing idle capacity as though it were guaranteed revenue. Keep contribution margin, avoidable cost and machine-cost assumptions non-duplicative.
