Shipping and freight

Work Out What a Shipment Will Actually Cost to Move

Carriers do not bill the number on your scale. They bill whichever is greater: actual weight or a volume-derived weight, and for LTL they bill by density class. These five tools turn carton dimensions into the numbers a carrier quotes from.

CBM calculator Carton and shipment volume in cubic metres, how many fit a 20ft, 40ft or 40HC container with utilisation percentage, and the bridge from CBM to volumetric and chargeable weight. Sea freight, container planning, supplier quotes Volumetric weight calculator One carton profile compared across express (÷5000), air and road freight (÷6000), sea LCL revenue tonne, and your own rate-card divisor — with the billable weight and DIM gap for each. Comparing carriers before you book Dimensional weight calculator US-flavoured DIM weight for courier and parcel shipments, using the divisors the major carriers apply to domestic parcels. Parcel and courier shipments Chargeable weight calculator The weight a carrier will actually bill, compared side by side across air freight (÷6000), express courier (÷5000), sea LCL revenue tonnes and inland — in centimetres and kilograms or inches and pounds, with CBM and CFT alongside. Checking a quote before you accept it Freight class calculator Dimensions and weight to density to NMFC class on the current 2025 13-class density scale, with the full chart highlighted at your result and how far you are from the next cheaper class.

Compare What Fulfilment Providers Are Really Charging

Fulfilment quotes are hard to compare because no two providers break their pricing down the same way. These two put competing quotes onto the same cost lines so the cheapest headline rate stops winning by default.

3PL cost calculator Receiving, storage, pick and pack, packaging and shipping rolled into a true fulfilment cost per order, so you can see what a provider costs at your actual order profile.

Ordering stock from suppliers Proforma invoice generator Seller, buyer and consignee, Incoterms and named place, HS code and country of origin on every line, package and weight totals, and a declaration block — the document you issue before goods ship.

How they fit together

From Purchase Order to Delivered Parcel

The tools follow the order of a real inbound-to-outbound cycle, and most of them hand a number to the next one.

  1. Raise the order. Build the purchase order for your supplier, with line items, tax and delivery terms, and send it as a PDF.
  2. Size the inbound shipment. Convert the supplier's carton dimensions into CBM to see how much container or pallet space the order needs.
  3. Check how it will be billed. Run the same cartons through volumetric or dimensional weight to find the billable weight, or freight class if it is moving LTL in the US.
  4. Cost the fulfilment side. Work out cost per order, and compare provider quotes on identical line items before you commit.
