In another scenario, in a 24/7 facility, the equipment would be scheduled with no idle hours, and the total available hours would be 168. If the machine runs 85 hours, the utilization rate would be 51%. 85 Run Hours/168 Available Hours x 100 = 51% utilization. This formula shows you how to calculate machine utilization.
