When sending a parcel 5kg and over, or overseas, postage is based on the weight or cubic weight (whichever is greater) and the destination. Read our guide on how to calculate your postage, or use our online calculator to estimate the postage price and delivery time to send your letter or parcel within Australia or overseas.
Cubic weight is the cubic volume of a package, multiplied by 250.
To calculate:
- Measure the package dimensions (length, width and height) in centimetres
- Calculate L x W x H, then multiply this by 250
- This final result is the package’s cubic weight, in kg
Actual weight is the physical weight of your package when it’s put on the scales. It’s usually measured in kg.
Chargeable weight is the weight we charge for postage. It’s whichever is greater between cubic and actual weight. So, if a package’s cubic weight is 15kg and actual weight is 10kg, its chargeable weight is 15kg.
