uk import duty calculator

How this UK import duty calculator works

When goods come into the UK, the final amount you pay can include several different charges: customs duty, import VAT, excise duty (if applicable), and sometimes a courier admin fee. This calculator gives you a practical estimate so you can avoid unexpected costs before ordering.

The tool is designed for everyday buyers and small business users who need a quick estimate. You can update duty rate, VAT rate, and extra fees to match your own shipment.

What charges are included?

• Customs value: usually goods value + shipping + insurance (+ other customs additions).
• Customs duty: percentage based on your commodity code and origin rules.
• Import VAT: calculated on customs value + duty + excise (where relevant).
• Excise duty: applies to specific products, such as alcohol and tobacco.
• Courier/handling fee: a carrier charge, separate from HMRC taxes.

UK thresholds (simple guide)

Online purchases

For many consumer purchases with a goods value of £135 or less, import VAT is often collected at checkout by the seller or online marketplace, and border import duty usually does not apply. For consignments above £135, duty and import VAT are commonly collected at import.

Gifts

Gifts sent from one private person to another have different relief rules:

• Up to £39: typically no import VAT or duty.
• Over £39 to £135: VAT may apply, duty generally does not.
• Over £135: both duty and VAT may apply.

This calculator follows these common rules for estimation. Final treatment can depend on declaration quality, product type, and HMRC review.

Calculation method used

Step 1: Build customs value

Customs value = goods value + shipping + insurance + other customs costs.

Step 2: Calculate customs duty (if applicable)

Customs duty = customs value × duty rate.

Step 3: Calculate import VAT (if applicable)

Import VAT = (customs value + customs duty + excise duty) × VAT rate.

Step 4: Add any courier fee

Total payable = customs duty + import VAT + excise duty + courier fee.

Example

Suppose you order electronics worth £300 with £25 shipping, no insurance, duty rate 2.5%, and VAT 20%:

• Customs value: £325
• Duty: £325 × 2.5% = £8.13
• VAT: (£325 + £8.13) × 20% = £66.63
• Total taxes (before courier fee): £74.76

If your courier also charges an £11 handling fee, the final amount due on delivery becomes £85.76.

How to improve accuracy

• Use the correct commodity code to get the right duty percentage.
• Check if your goods qualify for a reduced or zero tariff under trade agreements.
• Confirm whether VAT was already collected at checkout.
• Ask your courier about any clearance/admin charges before shipment.
• Keep invoices and shipping evidence in case customs requests clarification.
