Chargeable Weight Calculator

Compare actual and volumetric shipment mass without a carrier billing guarantee.

METHODOLOGY

How estimated chargeable mass is compared

ShipmentPrep compares complete actual shipment mass with the current volumetric mass in canonical kilograms, before presentation rounding.

Formula

Estimated chargeable mass = max(actual mass, volumetric mass)

The exact comparison state is ACTUAL_GREATER, VOLUMETRIC_GREATER or EQUAL_EXACT.

Worked example

Actual mass120 kg
Volumetric mass120 kg
Estimated chargeable mass120 kg
ComparisonEqual exactly

What the result means

This is an estimated chargeable mass, not a guaranteed carrier billable weight. Actual mass is required; incomplete multi-carton mass never produces a fabricated comparison.

Assumptions & limits

Carrier billing may apply additional service-specific measurement, rounding, minimum-weight or contractual rules.
