Container utilisation calculator

Methodology

Usable volume = internal volume × (1 − stowage loss). Maximum units by volume = usable volume ÷ unit volume, rounded down. Maximum units by weight = payload capacity ÷ unit weight, rounded down. Units loaded is the lowest of those two limits and the units you actually have, and the binding constraint names which one applied. Utilisation percentages compare the loaded volume and weight with the container's usable volume and payload capacity. Internal volume and payload capacity vary by container type, build, and tare, so enter the figures for your actual equipment. The model does not evaluate stacking strength, weight distribution, axle limits on the road leg, or securing requirements. You supply every input: this site holds no live freight rates, transit times, or duty tables, and never estimates them for you. Results are an orientation model, not a quotation, and not customs, tax, insurance, or financial advice. Confirm duty rates, VAT treatment, and carrier terms with the relevant authority or provider before relying on them.
