Volumetric & Chargeable Weight Calculator
Couriers charge for whichever is greater: actual weight or volumetric weight. Enter your carton’s dimensions and weight to see the chargeable weight per parcel and for the whole shipment — and whether an oversized box is costing you more than it should.

How it works
Three simple steps
-
Enter carton dimensions
Outer length, width and height in centimetres, after packing.
-
Enter weight and quantity
Actual parcel weight in kilograms, and the number of identical parcels.
-
Pick your courier’s divisor
Check the divisor and rounding rule in your contract or on the courier’s site.
Why is there a volumetric weight?
A light but large parcel takes up as much space in a plane or truck as a heavy one. So couriers calculate a “volumetric weight” from the dimensions and charge for whichever is greater — that or the actual weight.
The divisor varies between couriers and services (5000 and 6000 are common), as does the rounding rule. The tool gives you an accurate calculation, but the final reference is your courier’s terms.
FAQ
Good to know
How is volumetric weight calculated?
Length × width × height (in cm) ÷ divisor. Example: a 40 × 30 × 20 cm carton with a divisor of 5000 = 4.8 kg.
What is chargeable weight?
The greater of actual weight and volumetric weight — the figure shipping cost is based on.
Which divisor should I use?
It depends on the courier and service (domestic, express international, air). 5000 is common for express services, and 6000 is used by some couriers and services. Check your contract or the courier’s website.
How can I reduce volumetric weight?
Use cartons sized to the product instead of one large standard box, reduce empty space and filler, and test several carton sizes for your best-sellers.
