Pallet utilisation calculator

Methodology

Cartons per layer is the better of two axis-aligned orientations: (pallet length ÷ carton length) × (pallet width ÷ carton width), or the same with the carton rotated a quarter turn, each rounded down. Usable height = maximum stack height − pallet base height; layers = usable height ÷ carton height, rounded down. Cartons by volume = cartons per layer × layers. Cartons by weight = maximum pallet weight ÷ carton weight, rounded down. Cartons per pallet is the lower of the two, and the binding constraint names which limit applied first. Volume utilisation compares total carton volume with the usable pallet envelope. The model assumes uniform cartons in a regular block pattern with no overhang: it does not evaluate interlocked or pinwheel patterns, load stability, crush strength, slip sheets, or carrier-specific overhang tolerances. 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.
