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

OEE can also be calculated using the simple calculation. Formula: (Good Count × Ideal Cycle Time) / Planned Production Time. Example: (18,848 widgets × 1.0 seconds) / (420 minutes × 60 seconds) = 0.7479 (74.79%) The result is the same in both cases. The OEE for this shift is 74.79%.
