Courier volumetric weight calculator
Volumetric weight (kg) = length × width × height in cm ÷ divisor. Most Indian couriers use a divisor of 5000. You bill the higher of the actual and volumetric weight, usually rounded up to the next 0.5 kg.
Worked example
A box of 30 × 20 × 15 cm weighing 1.2 kg: 30 × 20 × 15 = 9,000. Divided by 5000, that is 1.8 kg volumetric. Because 1.8 kg is more than 1.2 kg, you bill on 1.8 kg, which rounds up to 2 kg.
Volumetric weight questions
How is volumetric weight calculated?
Multiply the box's length, width and height in centimetres, then divide by the network's divisor. Most Indian couriers use 5000 for air and express parcels, though some services use 4750 or 6000. The chargeable weight is whichever is higher: the actual weight or the volumetric weight.
What is chargeable weight?
Chargeable weight is the weight you bill the customer for. It is the higher of the actual weight on the scale and the volumetric weight worked out from the box size.
Why do couriers charge by volume?
A large, light box takes up as much space in a van or aircraft as a heavy one. Charging by volumetric weight makes sure bulky parcels are priced for the space they use.
Which divisor should I use?
Check the current rate card from your network for each service you sell. The divisor can differ between air, surface and premium services.
