How to use this duty UK calculator

If you buy goods from outside the United Kingdom, your final cost can be higher than the checkout price. This duty UK calculator helps you estimate what you may owe at import: customs duty, import VAT, and any fixed excise charges.

To get a quick estimate, enter your item value, shipping, and insurance. Then set your expected duty rate and VAT rate. If your goods are alcohol, tobacco, or fuel, include estimated excise or fixed charges as well.

What charges are included in UK imports?

1) Customs value

Customs value is usually the value of goods plus shipping and insurance up to the UK border. This is the base used to calculate customs duty.

2) Customs duty

Customs duty is often based on the commodity code (also called tariff code) for your product. Different categories have different rates. Some goods can have a 0% rate, while others are much higher.

3) Import VAT

Import VAT is generally charged on a broader base than duty. In many cases, VAT is calculated on customs value + customs duty + certain extra costs. The standard UK VAT rate is often 20%, but reduced rates can apply for specific goods.

4) Excise and admin fees

Excise applies to certain products (for example alcohol and tobacco). In practice, many buyers also pay courier handling or clearance fees. This tool has an optional field to help you include those costs in your estimate.

Calculation method used

• Customs value = goods value + shipping + insurance
• Duty = customs value × duty rate
• VAT base = customs value + duty + excise/fixed charges
• VAT = VAT base × VAT rate
• Total import taxes = duty + VAT + excise/fixed charges
• Landed cost = goods + shipping + insurance + total import taxes

Example import scenario

Imagine you buy an item for £400, shipping is £40, insurance is £10, duty rate is 4%, and VAT is 20%:

• Customs value: £450
• Duty: £18
• VAT base: £468
• VAT: £93.60
• Total taxes: £111.60
• Estimated landed cost: £561.60

This is exactly why import planning matters: your real cost can be significantly above product price alone.

Tips to improve estimate accuracy

• Find the correct UK commodity code before placing large orders.
• Check whether your goods qualify for preferential rates by origin.
• Confirm if VAT is prepaid at checkout for low-value consignments.
• Ask your courier about brokerage or clearance fees.
• Keep invoices and shipping documents consistent and detailed.

Important notes

UK import rules can change, and specific products may have special treatment. This calculator is best used for budgeting and comparison, not as a formal customs declaration tool. For commercial imports or high-value shipments, verify rates with HMRC guidance or a licensed customs broker.
