How to Calculate Landed Cost on Imported Stock
The price on a supplier’s quote is rarely the price you end up paying. By the time a pallet of imported goods sits in your storeroom, it has picked up freight, insurance, duties, handling fees and probably a few surprises. The total, expressed per unit, is the landed cost. Getting landed cost calculation right is the difference between a product that looks profitable and one that actually is.
This article gives you a repeatable method, a template with placeholders for your own numbers, and a list of the costs that most often get missed. Duty rates, fees and rules change, so we point you to official sources instead of quoting figures that could be out of date.
What landed cost includes
Landed cost is everything it costs to get a product from the supplier’s door to yours, ready to sell, divided by the number of sellable units. The components usually fall into five groups.
- Product cost: the price of the goods, in the supplier’s currency, plus any tooling, sample or customisation fees spread across the order.
- Transport: pre-carriage in the origin country, main freight (sea, air, road or rail), and onward delivery in the UK.
- Insurance: cover for goods in transit, if not included in the shipping terms.
- Duties and taxes: customs duty, import VAT and any other applicable charges.
- Handling and fees: customs clearance or broker fees, port or terminal charges, inspection costs, bank and currency charges, storage if goods wait.
Add them up, then divide by units you can actually sell, not the units you ordered. If you expect a small percentage of damaged or defective items, your cost per sellable unit rises accordingly.
Step 1: Understand the shipping terms
Quotes use shorthand called Incoterms that say who pays for what and where risk passes. Two buyers can be quoted the same product price and face very different costs depending on terms.
| Term | Rough meaning (check the exact wording) |
|---|---|
| EXW | You collect from the supplier’s premises and handle almost everything |
| FOB | Supplier delivers goods onto the vessel at the origin port; you pay main freight onward |
| CIF | Supplier pays freight and insurance to the destination port; you handle import clearance and onward |
| DDP | Supplier delivers to your door with duties paid; price is higher but simpler |
Always ask exactly which version of the rules applies and which named place is stated. The terms define which costs are yours, so a list of “extra” charges for one quote might already be included in another.
Step 2: Convert the currency honestly
If you pay in dollars, euros or another currency, the exchange rate matters twice: when you quote and when you pay. Use a realistic rate, not the best one you saw last month, and include the bank or payment provider’s conversion charge. For larger or repeated orders, ask your bank or a foreign exchange provider about forward contracts that fix a rate in advance. Cover brings certainty but also commits you, so take advice before using it.
Step 3: Find duty and VAT treatment
Customs duty depends on what the product is, where it comes from and whether any trade agreement applies.
- Classification: every product has a commodity code that determines its duty rate. Finding the right one is the step most people get wrong. Use the government’s tariff lookup and, if unsure, ask your freight forwarder or customs agent.
- Origin: preferential rates may be available if the goods qualify under a trade agreement, which usually requires proof of origin.
- Valuation: duty is generally calculated on the customs value, which can include freight and insurance up to the UK border, not just the product price.
- Import VAT: charged on importation. If you are VAT-registered, you can often account for and reclaim it according to the rules, but cash flow timing varies depending on how you account for it. Speak to your accountant.
- Other charges: some goods attract excise duties or additional restrictions.
Duty and tax rules are technical and change. For anything you import regularly, a short conversation with a customs broker or accountant is worth more than guesswork.
Step 4: Build the calculation
Here is a template. Replace every bracketed field with your own numbers from written quotes.
| Line | Amount per shipment |
|---|---|
| Goods (converted to GBP) | [CẦN ĐIỀN] |
| Tooling / sample share | [CẦN ĐIỀN] |
| Origin charges and pre-carriage | [CẦN ĐIỀN] |
| Main freight | [CẦN ĐIỀN] |
| Insurance | [CẦN ĐIỀN] |
| Customs duty | [CẦN ĐIỀN] |
| Customs clearance / broker fee | [CẦN ĐIỀN] |
| Port / terminal / handling charges | [CẦN ĐIỀN] |
| UK delivery to warehouse | [CẦN ĐIỀN] |
| Bank / FX charges | [CẦN ĐIỀN] |
| Total landed cost (ex-recoverable VAT) | sum |
| Sellable units (after allowance for damage) | [CẦN ĐIỀN] |
| Landed cost per sellable unit | total ÷ units |
Note the label “ex-recoverable VAT”. If you can reclaim import VAT, it does not belong in your cost, though it affects cash flow in the interim. If you cannot reclaim it, it is a cost and should be included.
Step 5: Allocate costs fairly across a mixed shipment
If a container holds several products, shared costs such as freight need a rule for splitting them. Common methods:
- By value: heavier share to the expensive goods. Easy but can overcharge high-value light items.
- By weight or volume: closer to how carriers charge, better for bulky goods.
- By units: simple, suitable when products are similar in size.
Choose one that reflects how the cost arises and use it consistently. Whichever you choose, record it so that next quarter’s numbers are comparable.
Step 6: Add the hidden costs people forget
- Demurrage and storage if a container sits at the port because documents or payments are late.
- Inspection and testing fees, particularly for regulated products.
- Repacking or relabelling to meet UK requirements.
- Rejected or non-compliant goods, which may have to be reworked, re-exported or destroyed.
- Customs delays that push you into buying extra stock elsewhere.
- Cost of capital: money paid months before the goods can be sold. Even if you do not charge yourself interest, it is a real constraint.
Step 7: Compare against your selling price
Once you have the landed cost per unit, test viability:
Selling price (ex-VAT) − landed cost − selling costs (fees, packaging, outbound delivery) − returns allowance = margin per unit
If the margin is too thin to survive a rise in freight rates or a weaker pound, the product is fragile. A useful habit is to calculate a “stress case” with higher freight and a worse exchange rate, and ask whether the product still works.
Frequently asked questions
Is landed cost the same as cost of goods sold?
Landed cost feeds into cost of goods, but your accounting treatment depends on your situation and should be agreed with your accountant.
Do I need a customs broker?
Not always, but many small importers use one or a freight forwarder with clearance services. They help with classification, declarations and avoiding delays.
How often should I recalculate?
Every time a quote, rate or exchange rate changes materially, and at minimum for each new shipment.
Does landed cost matter for UK-sourced stock?
Yes, in a simpler form: delivery, handling and storage still add to the price, though duties do not arise on domestic purchases.

Conclusion
Landed cost calculation turns a tempting quote into a real number. List every cost from factory gate to your shelf, use the shipping terms to decide who pays what, convert currency realistically, divide by sellable units, and stress test the margin. Take your next quote and run it through the template before you say yes.
