SPREADSHEETKakobuy shipping cost: actual weight, volumetric weight and final packing
Learn why the cheapest-looking item or the lightest warehouse weight may not produce the lowest parcel charge.

Three measurements to keep separate
The product’s weight is not the same as the packed parcel’s weight. Packaging adds material, and a carrier can also use a volumetric measure of the space occupied. Kakobuy’s weight help distinguishes item weight from the final package. When comparing options, write down which figure the quote uses. A bare “2 kg” without its measurement basis is not enough to make a reliable comparison.
How volumetric weight works
The official volumetric-weight page gives length × width × height in centimetres, divided by a carrier-specific divisor, and describes comparison with actual weight for applicable lines. It lists different possible divisors; do not apply one divisor to every route. First find the chosen line’s billing rule, dimensions and rounding method, then calculate. The formula is a tool for understanding a quote, not a replacement for it.
A clearly labelled example
Suppose a box measures 40 × 30 × 20 cm and a hypothetical line uses a divisor of 6000. The volume is 24,000 cm³ and the volumetric result is 4 kg. If the actual parcel is 2.5 kg and that line bills the larger figure, the comparison starts from 4 kg before its rounding or extra charges. These are invented teaching inputs, not a live Kakobuy rate or a recommended parcel size.
Why the amount can change after packing
The official weight guidance describes an initial freight collection followed by adjustment after packaging: an excess can go back to balance and a shortfall may require payment. Do not compare the initial item-weight estimate with another line’s fully packed quote as though they were identical. Keep both stages of the quotation, including the measured size, so you can ask a precise question if the adjustment is unexpected.
Compare the complete route offer
For a useful comparison, keep destination, contents and packaging assumptions the same. Then compare the line’s quoted total, weight basis, limits and delivery information shown at submission. A lower volumetric figure alone does not establish the lowest total. Treat any packaging change as a trade-off: reducing bulk can affect the protection you want for fragile or presentation-sensitive goods. Ask for the current available options rather than assuming every service is available.
