Volumetric freight charge: practical guide
This guide explains how to use the Count.ie volumetric freight charge. Compare actual and dimensional weight and calculate a carrier charge. Follow the inputs, method and worked example below, then compare your own scenario.
Guide written .
Open the Volumetric freight charge calculatorWhat to prepare
- Gather order history, item dimensions, weights and supplier lead times.
- Identify the same units and planning period across stock, demand and capacity inputs.
- Check which freight, storage, import or production costs the model includes.
Understand the inputs
The calculation method
Dimensional weight = length × width × height ÷ carrier divisor; chargeable weight is the greater of actual and dimensional weight.
Worked example
Illustrative inputs and their result.
Example inputs
- Identical parcel count
- 5
- Parcel length (cm)
- 60
- Parcel width (cm)
- 40
- Parcel height (cm)
- 30
- Actual gross weight per parcel (kg)
- 10
- Carrier volumetric divisor (cm³/kg)
- 5000
- Freight rate per chargeable kg (€)
- 2.5
- Minimum shipment charge (€)
- 20
- Fuel surcharge on base freight (%)
- 12
- Other charges (€)
- 10
Calculated example result
- Total Freight Charge
- €211.60
- Chargeable Weight Kg
- 72 kg
- Dimensional Weight Kg Each
- 14.4
How to interpret the result
A capacity, inventory or landed-cost estimate is not a guarantee of service availability. Variability in demand, lead time, packing and customs treatment can change the operating result.
Keep the service requirement fixed while testing demand, lead time or shipment size. Check practical constraints such as handling, access and supplier minimum quantities separately.
Common mistakes to avoid
- Do not mix usable capacity with nominal capacity.
- Keep net goods weight separate from packaged or shipping weight.
- Do not treat a supplier's usual lead time as a guaranteed maximum.
Assumptions and sources
Carrier rounding, per-parcel minimums, zones and VAT are not inferred. Minimum charge applies to the shipment.
