How this is calculated
Volumetric weight = L × W × H ÷ divisor. Chargeable = the greater of actual and volumetric. Cost = Chargeable × Rate.
Couriers round chargeable weight up to the next slab (often 500g), so your real bill is usually a little higher than this. Fuel surcharge, COD fees and zone-based rates are not included.
