How it's calculated
The price on your supplier's invoice is only part of what an imported product costs. The calculator adds freight and insurance to find the customs value, charges duty on it, charges import VAT on the customs value plus duty plus onward transport, and adds your other costs, then divides by the number of units.
In the EU, the customs value includes "the cost of transport and insurance of the imported goods" up to the point where they enter the EU, but not transport after that (Union Customs Code, arts. 71 and 72). Import VAT is charged on the customs value plus duties and incidental costs up to the first destination.European Commission HMRC uses the same approach for UK imports.HM Revenue & Customs
The formula
- Customs value (CIF) = goods + freight + insurance to the border
- Duty = customs value × duty rate (EU consignments of €150 or less: €3 per item since 1 July 2026)EUR-Lex
- Import VAT = (customs value + duty + transport to the first destination) × VAT rate
- Landed cost = customs value + duty + import VAT (unless reclaimed) + onward transport + other costs
- Per unit = landed cost ÷ units
Worked example
A shipment of 500 units costing €10,000, with €1,200 of freight and €100 of insurance, has a customs value of €11,300. At a 12% duty rate the duty is €1,356 and import VAT at 19% is €2,462. With €550 of transport and other costs and the VAT reclaimed, each unit lands at €26.41.
| Line | Amount |
|---|---|
| Goods (supplier price) | €10,000 |
| Freight to the border | €1,200 |
| Insurance | €100 |
| Customs value (CIF) | €11,300 |
| Customs duty | €1,356 |
| Transport to the first destination | €300 |
| Import VAT (19% of €12,956) | €2,462 |
| Other costs (broker, fees, storage) | €250 |
| Cash paid out | €15,668 |
| Import VAT reclaimed | -€2,462 |
| Landed cost | €13,206 |
If the import VAT cannot be reclaimed, the landed cost per unit rises to €31.34.
Assumptions and limitations
- One duty rate for the whole shipment; mixed shipments need a rate per commodity code.
- Ad valorem duty only. Specific duties (per kilo or per litre), anti-dumping duties, excise and quotas are not covered.
- Preferential origin under a trade agreement can reduce the duty to 0%: enter the rate that applies to you.
- One currency. Convert supplier prices at the exchange rate customs uses for the month of import.
