About this tool
What the Customs Duty Calculator does
Import charges usually have two parts: customs duty on the customs value, and import VAT or GST charged on the customs value plus the duty. Whether freight and insurance are included in the customs value depends on the country, so this calculator lets you choose.
Formula
- Customs value = goods (FOB) or goods + freight + insurance (CIF)
- Duty = customs value × duty rate
- Import VAT = (goods + freight + insurance + duty) × VAT rate
Worked example
Using the starting values in the calculator above:
| Input | Value |

| Customs value basis | CIF (goods + freight + insurance) |
| Duty rate | 5% |
| Import VAT or GST rate | 20% |
| Other import fees | $150 |
| Result | Value |
|---|---|
| Total import charges | $2,984 |
| Customs duty | $545 |
| Import VAT or GST | $2,289 |
| Customs value | $10,900 |
| Total landed cost | $13,884 |
How to read the result
Duty rates depend on the product’s tariff classification and origin; free trade agreements can reduce them to zero if rules of origin are met.
VAT-registered businesses can usually reclaim import VAT, so it affects cash flow more than final cost.
Estimates only. Customs valuation and rates depend on classification, origin and local rules; check with the customs authority or a broker.
