Logistics Calculators

Plan shipments and freight costs.

About our logistics

Logistics calculators handle the arithmetic that decides what a shipment costs and whether it fits — dimensional weight, cubic metres, how many cartons fit on a pallet, freight density and class, the landed cost of imported goods, and how much a container will hold. Freight is priced on whichever is greater, actual weight or the space a parcel occupies, so a light but bulky box can cost far more than its scale weight suggests, and getting these numbers wrong turns a thin margin into a loss. Importers, e-commerce sellers, warehouse teams and shipping coordinators use these tools to quote accurately, compare carriers, and plan how goods stack and travel. Each tool applies the standard method carriers themselves use — dimensional weight as length times width times height divided by a dimensional factor, cubic metres from the same dimensions, pallet and container fit from unit and load dimensions, and landed cost as the sum of goods, freight, duty and handling — and shows the formula and a worked example so the figure is transparent. The limitation to keep in mind is that carriers set their own dimensional divisors, duty rates depend on commodity codes and country of origin, and real-world stacking is constrained by weight limits, fragility and load stability that a pure volume calculation cannot see. Treat the results as accurate for the inputs you provide, then confirm the dimensional factor, tariff and pallet configuration with your carrier or customs broker before booking a shipment.

Common questions about logistics

What is dimensional weight and why do carriers use it?

Dimensional weight prices a shipment by the space it occupies rather than its actual mass. Carriers calculate it by multiplying length, width and height and dividing by a dimensional factor they set, then bill whichever is greater — the dimensional or the actual weight. This stops light, bulky parcels from taking up van space cheaply. Because each carrier uses a different divisor, always check theirs, since it directly changes the price you pay.

How do I calculate the CBM of a shipment?

Cubic metres, or CBM, measures the volume a shipment occupies. Multiply the length, width and height of each carton in metres, then add the cartons together. A box of 0.5 by 0.4 by 0.3 metres is 0.06 CBM, so ten of them make 0.6 CBM. Sea freight is often priced per cubic metre, so an accurate CBM figure is essential for quoting and planning how much fits in a container.

What is landed cost and why does it matter?

Landed cost is the total price of getting a product to your door — the goods plus freight, insurance, import duty, customs fees and handling. It matters because the sticker price of imported goods hides these additions, and a product that looks cheap at the factory can become unprofitable once duty and shipping are added. Calculating it before you order reveals your true unit cost, so you can price for profit before the gap appears.
