What is a Import Duty Calculator?

An Import Duty Calculator helps importers estimate the customs duties, tariffs, and taxes they'll pay when bringing goods into a country. In 2026, with the US imposing elevated tariffs on goods from China (44% total), the EU (20%), Japan (24%), and many other trading partners, calculating import costs has never been more important. Duties are typically calculated as a percentage of the CIF (Cost, Insurance, Freight) value of the goods. VAT or GST is then applied on top of the duty-paid value. This calculator helps you budget for these unavoidable import costs.

How Does It Work?

Enter your product's FOB value and freight/insurance costs to determine the CIF (customs value). Then enter the applicable tariff rate and any additional surcharges (such as Section 301 tariffs). The calculator applies duty to the CIF value, then VAT/GST to the duty-paid total. Preset scenarios for major 2026 trade routes help you quickly model different sourcing options.

Formula

CIF = Product Value + Freight + Insurance\nTotal Duty Rate = Base Tariff% + Additional Tariff%\nDuty Amount = CIF × Total Duty Rate%\nVAT Amount = (CIF + Duty) × VAT%\nTotal Import Cost = CIF + Duty + VAT

Frequently Asked Questions about Import Duty Calculator

What's the difference between a tariff and a duty?

They're often used interchangeably, but technically: a tariff is the tax rate schedule (the %), while a duty is the actual tax amount paid. A 25% tariff on \$10,000 CIF = \$2,500 in duties.

Can I get my duties refunded?

Yes, through Duty Drawback programs. If you import goods and later export them (or products made from them), you can recover up to 99% of duties paid. This is underutilized — many importers leave money on the table.
