The working
How this is calculated
CIF value = product value + freight + insurance
Customs value = CIF (EU, UK, China, most countries)
= FOB (United States - goods value only)
Duty = customs value × duty %
Tax base = customs value + duty ← common, NOT universal
Tax = tax base × tax %
Total = CIF + duty + tax + other fees
Per unit = total ÷ units
Assumptions
- The duty basis is yours to choose and it matters more than any other setting here. The EU, UK, China and most countries assess duty on the CIF value. The United States assesses on FOB - the goods value alone, with international freight and insurance excluded. Leaving this on CIF for a US import overstates the duty on every shipment.
- Import tax is applied to the customs value plus duty. That is the common pattern in VAT and GST systems, but it is not universal - some countries tax the customs value alone. Check your own before relying on the tax line.
- Duty and tax percentages are yours to supply. This calculator has no HS code database and does not guess a rate from a product description. Get the rate from your customs broker or your country's own tariff schedule.
- Duty is calculated on the whole customs value. Preferential rates under a trade agreement, de minimis thresholds, and anti-dumping duties are not modelled.
- Other fees is a flat amount added after tax - broker fees, port charges, inland delivery. It is not included in either the duty base or the tax base.
- Every figure is in one currency. Exchange rate movement between order and clearance is not modelled, and on a long lead time it can move the landed cost by more than the duty line does.
How to use this landed cost calculator
Enter the product value, the freight and the insurance, then your duty and import tax percentages. Add any flat broker, port or inland delivery charges under other fees, and the unit count if you want the per-unit figure as well as the total.
Two controls matter more than the numbers. Duty is assessed on sets whether the duty rate is applied to the CIF value or to the goods value alone, and import tax is charged on sets whether the tax base includes the duty. Both differ by destination, and both are the difference between a total landed cost you can quote and one you cannot.
The result updates as you type, with every step of the cascade printed underneath. Nothing is sent to a server, and the numbers live in the page address, so copying the link sends the exact calculation to a broker or a colleague with the fields already filled in.
Worked example
You are importing 1,000 units. The numbers on the table are:
- Product value: 12,000
- Freight: 2,400
- Insurance: 90
- Duty rate: 6.5%
- Import tax rate: 20%
- Broker and handling fees: 250
Work through it in order.
CIF value. 12,000 + 2,400 + 90 = 14,490. This is the value the border sees, not the 12,000 on the supplier’s invoice.
Duty. 14,490 × 6.5% = 941.85.
Tax base. 14,490 + 941.85 = 15,431.85. The duty is inside the tax base, which is why the tax line is larger than a naive calculation would suggest.
Import tax. 15,431.85 × 20% = 3,086.37.
Total landed cost. 14,490 + 941.85 + 3,086.37 + 250 = 18,768.22.
Per unit. 18,768.22 ÷ 1,000 = 18.77.
The unit you bought for 12.00 lands at 18.77 - 56 per cent above the purchase price. If you had priced this product off the supplier invoice with a target 40 per cent margin, you would be selling at 20.00 and making 1.23 a unit, not 8.00.
The cascade is where people go wrong
Notice that duty is calculated on the customs value rather than the invoice value, and that tax is calculated on the customs value plus duty, not on the customs value alone.
Both compound. Applying tax to the customs value alone rather than to customs value plus duty understates the tax by 188 in the example above. It is not a dramatic error on its own, but it quietly removes money from a calculation you were relying on for pricing, and the order of operations is the whole reason to do this in a calculator rather than in your head.
CIF or FOB: the setting that moves the number most
The example above uses CIF, which is what the EU, the UK, China and most countries assess duty against. The United States does not. US Customs appraises on transaction value - the price paid for the goods - and states directly that duty is not assessed on cost, insurance and freight charges. In practice that means the FOB goods value.
Run the same shipment both ways:
| Line | CIF basis | FOB basis (US) |
|---|---|---|
| Customs value | 14,490 | 12,000 |
| Duty at 6.5% | 941.85 | 780.00 |
| Tax base | 15,431.85 | 12,780.00 |
| Tax at 20% | 3,086.37 | 2,556.00 |
| Other fees | 250.00 | 250.00 |
| Total landed | 18,768.22 | 18,076.00 |
That is 692 of difference on a single shipment, from one dropdown - and it is 692 the US importer never actually owed. The gap scales with freight, so the more expensive the lane, the more a CIF-based calculator overstates the bill.
This is why the duty basis is a control on this page rather than a hidden assumption. If you are importing into the United States, set it to FOB.
Using it as a US, UK or B2B landed cost calculator
The arithmetic is the same everywhere. What changes is the two basis settings and what you do with the answer.
United States. Set the duty basis to FOB. US importers also face merchandise processing and harbour maintenance charges, which are not duty and belong under other fees rather than in the rate. There is no federal import VAT, so the tax line is often left at zero and the total is product plus freight plus duty plus fees.
United Kingdom and the EU. Leave the duty basis on CIF and the tax base on customs value plus duty, which is the standard VAT treatment. If you are VAT registered you will usually recover the import VAT as input tax, so run the total once with the tax line and once without - the first is the cash you have to fund at clearance, the second is the cost your margin actually carries.
B2B and wholesale. When you are quoting a trade customer rather than pricing a retail line, the number they want is the per-unit landed cost with the recoverable tax stripped out, plus your margin. Enter the unit count so the per-unit figure comes back with the total, and keep the working - a B2B buyer who queries a quote is usually querying the duty line, and showing the cascade settles it faster than a revised invoice does.
What makes a landed cost calculator accurate
Most tools get the arithmetic right and the assumptions wrong, which is worse than being obviously broken - a wrong total still looks like a total.
Three things separate an accurate calculation from a plausible one. The duty basis has to be yours to set. The tax base has to be yours to set. And the duty rate must not be guessed for you.
That last one is why there is no HS code lookup here. Duty rates hang off tariff classification, and classification is genuinely hard - the same physical product can fall into different headings depending on material composition, intended use and how it is presented for sale, and the rate difference between neighbouring codes can be more than ten percentage points. A calculator that infers a code from a product name would be confidently wrong a meaningful share of the time, and a confidently wrong duty rate gets used. Your customs broker gives you the classification and your country’s tariff schedule gives the rate against it. This tool does the cascade once you have both.
What this does not cover
Preferential duty rates under a free trade agreement can reduce the duty line to zero if your goods qualify and you have valid origin documentation. Anti-dumping and countervailing duties can add rates far above the standard tariff on specific goods from specific origins. De minimis thresholds may exempt small consignments entirely.
None of those are modelled here, and all of them can matter more than the arithmetic on this page. Treat the result as the standard-case figure, and confirm the exceptions with a broker before committing to a purchase order.
Currency movement is the other uncovered risk. On a ninety-day lead time, a five per cent move against you costs more than the entire duty line in this example.
