### Calculate OEE – Definitions, Formulas, and Examples | OEE

The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. Fully Productive Time is just another way of saying manufacturing only Good Parts as fast as possible (Ideal Cycle Time) with no Stop Time. Hence the calculation is: OEE = (Good Count × Ideal Cycle Time) / Planned Production Time
