Formula
Occupied storage cube ÷ usable storage cube × 100
How to use the result
Cubic utilization is a descriptive planning ratio. Do not treat total empty air in a building as available storage; fire protection, structure, equipment and handling needs can limit usable height.
What this calculator does not validate
It does not validate structural rack capacity, floor loading, safe material-handling clearances, fire protection, sprinkler requirements, exits, accessibility, equipment suitability or legal compliance. Use it for early planning and scenario comparison only.
Facility-specific decisions: confirm final dimensions and requirements with the applicable manufacturers, competent professionals and authorities in your jurisdiction.
