How volumetric weight works
Measure the outside of the box in cm: length × breadth × height.
Divide by the courier's divisor: 5000 for Delhivery and Shiprocket, 6000 for Aramex, 4500 for FedEx Surface.
Compare with the dead weight. The courier bills the greater of the two, rounded up to its weight slab.
Example: a 60 × 25 × 40 cm box weighing 8 kg. Volumetric weight = 60 × 25 × 40 ÷ 5000 = 12 kg. You are billed for 12 kg, not 8.
Questions
What is the courier volumetric weight formula?+
Volumetric weight (kg) = length × breadth × height in cm ÷ divisor. Delhivery and Shiprocket use 5000, Aramex 6000 and FedEx Surface 4500. You pay for the greater of the volumetric weight and the dead weight.
How does Delhivery calculate volumetric weight?+
Delhivery divides L × B × H in cm by 5000 for both surface and express. A 60 × 25 × 40 cm box is 60 × 25 × 40 ÷ 5000 = 12 kg, even if it weighs less.
Does Shiprocket round the size and weight?+
Yes. Shiprocket rounds each side up to the next whole centimetre, and the weight up to the next full kilogram, before it bills.
How do I lower my shipping cost?+
Trim the air out of the box. When volumetric weight decides the bill, taking 1 to 3 cm off one side often drops you into a lower slab. The right-size hint shows the smallest trim that does it.
