How It Works

Understanding the Calculation

What is Chargeable Weight?

Chargeable weight is the weight used to calculate your freight cost. It is the higher of actual gross weight and volumetric (dimensional) weight. This prevents large but light shipments from occupying cargo space at only actual weight cost.

Air Freight Formula

Volumetric weight for air freight = (L × W × H in cm × number of pieces) ÷ 6,000. This gives the equivalent weight in kg. Most air carriers use this divisor. Some carriers use 5,000 — check with your airline.

Ocean LCL Formula

For ocean LCL, the ratio is 1 CBM = 1,000 kg for pricing purposes. The chargeable measurement is the higher of actual weight (in kg) or CBM × 1,000. For dense cargo (tyres, metal parts), actual weight typically governs.

Questions About This Calculator

The divisor 6,000 is the IATA standard dimensional weight factor. It reflects the cargo capacity of aircraft — a cubic metre of cargo space costs the airline the same to fly whether it contains dense or light cargo. The factor converts volume to the equivalent revenue weight.

For dense cargo (actual weight significantly higher than volumetric weight), actual weight governs. For light, bulky cargo (packaging foam, inflatable goods), volumetric weight governs.

Yes. The actual weight used for chargeable weight calculation should be the gross weight including all packaging, inner packaging, and pallet weight. Do not omit pallet weight from your calculation.

Consider more compact packaging — smaller carton dimensions relative to product dimensions reduce the volumetric penalty. For some products, switching from retail packaging to bulk packaging can significantly reduce CBM and therefore volumetric weight.
