A supplier invoice rarely shows the true cost of imported stock. By the time cargo reaches your warehouse, international freight, customs duty, GST, insurance, port charges and local delivery can materially change the cost per unit. Knowing how to calculate landed cost gives Australian importers a clearer basis for purchasing decisions, product pricing and margin control.
For a small shipment, an overlooked terminal fee can erase the expected saving. For containerised freight or high-value cargo, an inaccurate estimate can affect cash flow across an entire product range. The objective is not simply to total invoices after arrival. It is to build a realistic, repeatable cost model before you commit to an order.
What landed cost includes
Landed cost is the complete cost of purchasing goods and bringing them to the point where they are available for sale, production or distribution. For most Australian imports, that point is your warehouse, distribution centre or nominated delivery location.
A practical landed cost calculation starts with the supplier’s goods value and adds every direct cost required to move, clear and receive the cargo. The exact items depend on the Incoterms, commodity, origin country, transport mode and delivery requirements.
The core formula is:
`Landed cost = goods value + origin costs + international freight + insurance + customs charges + Australian local charges + delivery to destination`
Depending on the shipment, your calculation may include:
- supplier packing, export documentation and origin handling
- sea freight, air freight and any fuel, security or peak-season surcharges
- cargo insurance
- customs duty, GST and any applicable additional taxes
- customs clearance, biosecurity, port, terminal, depot and document charges
- cartage, unpack, palletisation, warehousing and delivery costs.
Not every charge applies to every movement. Air freight may have different terminal and screening charges from sea freight, while LCL cargo commonly attracts destination charges that need careful review. Oversized machinery, vehicles and project cargo can also require specialised handling, permits, inspections or escort arrangements.
How to calculate landed cost before you place an order
A useful estimate should separate costs that are known from costs that are indicative. Supplier pricing and agreed freight rates may be fixed for a defined period, while storage, demurrage, detention, inspections and exchange-rate movements can remain variable. Allow for uncertainty rather than presenting a preliminary estimate as a final cost.
1. Confirm the Incoterm and supplier price
Start with the commercial invoice value and the agreed Incoterm. This determines which transport and handling costs are included in the supplier’s price, and where responsibility transfers.
For example, EXW pricing may leave the buyer responsible for collection from the supplier’s premises, export handling and freight onward. FOB pricing generally places the goods on board the vessel at the port of export, but does not include the ocean freight, marine insurance or Australian destination costs. CIF includes cost, insurance and freight to the destination port, but local clearance and delivery still sit with the importer.
Do not assume an Incoterm covers every charge. Confirm the named place or port, the freight inclusions and whether the supplier has added a margin to freight or insurance.
2. Calculate the customs value and duty
Australian customs duty is generally assessed against the customs value of the goods. In many cases, this is based on the transaction value paid or payable for the imported goods, converted into Australian dollars using the relevant customs exchange rate.
Duty rates vary by tariff classification and country of origin. Many products have a general duty rate of 5 per cent, but some are duty-free, while others are subject to different rates, trade agreement preferences, anti-dumping measures or additional requirements. The tariff classification, product description, composition and intended use all matter.
The basic duty calculation is:
`Customs duty = customs value x applicable duty rate`
A lower duty rate under a free trade agreement is not automatic. The goods must meet the relevant origin rules and be supported by appropriate origin documentation. Treat duty as a compliance calculation, not an assumption based on where your supplier is located.
3. Estimate import GST correctly
GST on imported goods is generally calculated at 10 per cent of the Value of Taxable Importation, often referred to as VoTI. Broadly, this includes the customs value, customs duty, international transport and insurance to the Australian port or airport, plus any wine equalisation tax where applicable.
`Import GST = VoTI x 10%`
For GST-registered businesses making creditable acquisitions, import GST may be recoverable through the business activity statement. That means it can be a cash-flow requirement without being a permanent inventory cost. Whether to include it in your product margin calculation depends on your accounting treatment and eligibility to claim an input tax credit.
This distinction is commercially significant. Keep two figures where necessary: a cash landed cost that includes GST payable at import, and a net landed cost that excludes recoverable GST. Your finance team and customs broker should confirm the treatment for your circumstances.
4. Add freight, insurance and destination charges
Freight is more than the rate shown on a booking confirmation. Include the full transport path covered by your purchase terms, from origin collection where required through to delivery at your Australian premises.
For sea freight, this may involve origin documentation, container packing or consolidation, ocean freight, terminal handling, destination documentation, unpack fees for LCL cargo, port or depot costs, customs clearance and cartage. For air freight, chargeable weight can materially affect the result, particularly for bulky but lightweight goods.
Insurance should also be considered even where the supplier has arranged it. Confirm the insured value, policy terms, exclusions and claims process. The cheapest freight arrangement is not always the lowest-risk option when goods are time-sensitive, fragile or high value.
At destination, request a clear schedule of expected charges. Customs clearance, import processing, biosecurity attendance, storage, container detention, wharf access and delivery waiting time may not be included in a headline freight quote. Some are avoidable through planning, while others depend on government direction, port conditions or how quickly documents and payments are provided.
5. Allocate the total cost to each product or unit
Once you have a shipment total, allocate the landed cost across stock in a way that reflects the real cost to your business. Dividing evenly by units works only where products are similar in value, size and handling requirements.
A shipment containing lightweight accessories and heavy tiles, for example, should not necessarily receive the same freight allocation per unit. Freight and local handling may be better allocated by weight, volume, pallet space or carton count. Duty is usually allocated according to the customs value of each product line.
Use a consistent allocation method and document it. This makes purchasing analysis more reliable and helps your team compare supplier offers, shipping modes and product margins over time.
A landed cost example for an Australian importer
Assume an importer purchases 1,000 units of a product from an overseas supplier on FOB terms. The goods value is AUD 20,000. International freight and insurance total AUD 3,000. Customs duty is 5 per cent of the customs value, or AUD 1,000. Australian clearance, terminal and delivery charges are AUD 2,000.
Before GST, the landed cost is AUD 26,000:
`20,000 goods value + 3,000 freight and insurance + 1,000 duty + 2,000 local charges = 26,000`
The estimated landed cost per unit is AUD 26. If the importer can claim the import GST credit, this is the more useful figure for ongoing margin analysis. If GST must be funded on import, it should still be included in short-term cash-flow planning.
The GST calculation will depend on the VoTI. In this example, using the customs value, duty, freight and insurance, the indicative VoTI is AUD 24,000 and GST is AUD 2,400. The business may therefore need AUD 28,400 available to clear and receive the shipment, even though its net stock cost remains AUD 26,000 where the GST is recoverable.
Common errors that distort landed cost
The most common issue is using the supplier invoice as the product cost and treating freight as a separate operational expense. That approach hides the true cost of stock and can lead to underpriced products.
Another error is relying on an old freight rate. Sea and air freight markets change, and charges may differ by season, equipment availability, destination terminal and shipment profile. Quotes should be checked against current cargo details, especially weight, dimensions, dangerous goods status and delivery postcode.
Importers can also underestimate the cost of delay. Missing documents, incorrect tariff classifications, biosecurity holds and late collection can result in storage, demurrage or detention. These costs should not be treated as inevitable. Accurate documents, realistic lead times and coordinated clearance reduce the exposure.
Finally, avoid applying one flat percentage to all imports. A useful budgeting allowance has a place, but it should be replaced with shipment-specific calculations for higher-value purchases, new suppliers, new commodities or unfamiliar trade lanes.
Build landed cost into procurement decisions
The strongest use of landed cost is before a purchase order is issued. Compare supplier offers on an equivalent delivered basis, not only on ex-factory or FOB pricing. A lower unit price may be offset by higher freight, poorer carton utilisation, additional duty or a greater risk of stock delays.
For regular imports, maintain a landed cost worksheet for each SKU or product family. Update it when supplier prices, exchange rates, tariff treatment, freight costs or local charges change. This provides procurement, sales and finance teams with a common commercial view of each shipment.
MCC World International can assist businesses with the freight, customs clearance and local delivery inputs needed to build more reliable import cost estimates. A clear landed cost model turns freight from an unexpected expense into a controlled part of your supply chain planning.
The best time to resolve a landed cost gap is before the cargo is booked, when you can still adjust the order quantity, shipping mode, selling price or delivery plan.
