What is Capacity Utilization?
Capacity utilization measures the extent to which a company uses its installed productive capacity, expressed as a percentage of maximum output. Calculated as (Actual Output / Maximum Possible Output) × 100, it indicates whether a company has room to grow production without additional capital investment or is constrained.
Optimal capacity utilization typically ranges from 80-90%. Below 80%, fixed costs are spread over too few units, raising per-unit costs and hurting margins. Above 90%, the system has little buffer for demand spikes, maintenance, or disruptions, leading to quality issues and employee burnout.
Capacity utilization varies across industries and has strategic implications. Airlines aim for high load factors (85%+) because empty seats are perishable revenue. Hotels target 70-80% occupancy to maintain service quality. Manufacturing plants might target 85% to allow for maintenance windows and demand variability.
In case interviews, capacity utilization is critical for investment decisions. Before recommending that a company build a new factory, check whether existing capacity is fully utilized. If a plant is running at 65% utilization, the better recommendation might be demand generation or production consolidation rather than capacity expansion.
Real-world example
During the 2020 pandemic, US airline capacity utilization dropped from 87% to below 30%. Airlines that quickly reduced capacity (parking planes, cutting routes) preserved cash better than those that maintained schedules hoping for demand recovery.
