How to Calculate Landed Costs: Duties, Taxes, and Fees

As an ecommerce merchant, determining shipping costs is an essential and ever-present part of doing business. At first glance, it doesn’t seem like it would be a complicated calculation—just put some information into an online tax and shipping calculator, hit enter, and go about your day, right? Not quite, but it’s a start.

The duties, taxes, fees, rules, and regulations associated with international shipping can be time-consuming and confusing for even the most experienced merchants. Costs, calculations, and guidelines can vary between countries or provinces and change frequently. Attempting to manage that many moving pieces while also running your ecommerce business is a more significant undertaking than you may think.

If you’re doing business that includes cross-border shipping, developing a complete understanding of landed costs is crucial to accurately estimating delivery costs and optimizing profits.

What Is the Difference Between Taxes, Duties, and, Fees?

The cost of shipping is just one part of the equation, especially if you’re selling to a global market. Once your product crosses an international border, you’ll most likely need to add additional taxes, duties, and/or tariffs to your cost estimate, along with various other fees.

Some of these terms can seem interchangeable since duties and tariffs are both types of taxes, so let’s dive in to define the difference     :

• Taxes: A tax is a source of government revenue placed on purchases and individuals to help fund government projects, programs, and public expenditures. Taxes are compulsory charges and a necessary part of doing business. Government fees placed on imported goods are referred to as sales tax, value-added tax (VAT), or goods and services tax (GST), depending on the country.
• Duties: Duties are indirect taxes that apply to financial transactions and goods. Duty fees may apply to goods manufactured locally (known as excise duties) or imported items (known as customs duties). They’re known as indirect taxes since they are imposed on the consumer; however, the seller pays the tax and usually passes on the cost in fees to the buyer.
• Tariffs: Tariffs are a direct tax that applies to certain imports or exports. Imported goods are classified under an HS code, which determines the tariff rates for various products. Tariffs are often leveraged to protect domestic manufacturers since they result in price increases, creating a loss of demand for imported products.
• Fees: There will also be fees associated with the shipping process. Fees can vary depending on the shipment details but may include brokerage, electronic filing, storage, formal clearance, and other miscellaneous costs.

HOW DO I CALCULATE THE TRUE LANDED COST OF A CROSS-BORDER ORDER?

Landed cost is the total of everything required to deliver a product to a customer's door in another country: 

Landed cost = product price + shipping & freight + duties + taxes (VAT/GST) + customs & ancillary fees 

Worked example (illustrative figures) — a $100 order shipped internationally from the US to the United Kingdom:

• Product Price: $100
• Shipping & freight: $18
• Duties: $12
• Import taxes (UK VAT at 20%): $26
• Customs and ancillary fees (brokerage, filing, handling): $7
• Total landed cost: $163

How to Calculate Duties and Taxes

Miscalculating total landed costs is an easy mistake to make but can quickly become an expensive and time-consuming logistical nightmare. Duty and tax charges are based on the following factors:

• Value of goods:  There's also a value ceiling for goods, referred to as de minimis, below which goods have historically not been charged duty or tax. That landscape has changed sharply: the US eliminated its $800 de minimis exemption in August 2025, and the EU removed its €150 exemption on July 1, 2026, so far more low-value shipments are now dutiable. De minimis still varies by country — see our country import and landed cost references for Mexico, the UK, Canada, Australia, and New Zealand for destination-specific rates. 
• Description of goods: The commercial invoice lists the product’s use and the country it was manufactured in to ensure the shipment is correctly classified.
• HS Code: An HS code helps classify the product type, which determines any taxes, duties, or regulations that may apply. It’s important that the HS code and description of goods both match.
• International commercial terms: International commercial (INCO) terms are part of an agreement that defines who is responsible for various costs throughout the shipping process. These are listed on the commercial invoice.

How to Calculate Duty Fees

To accurately calculate duty tax, you would need to find the duty rate for the goods you are shipping to the country you’re shipping to. The percentage will vary depending on location and is fluid, based on the local country’s schedule. You would use your product’s HS code or description to search for the duty cost of the particular product.

FlavorCloud automates duty cost calculations so that you can ship your products with confidence and avoid the complexity and confusion involved with having to research the many different components involved for each and every shipment.

How to Calculate Taxes

Calculating import taxes requires knowing the destination country’s sales tax rate (VAT). Some countries may have several different VAT rates depending on the good or service.

Duties and taxes usually must be paid before customs will release your goods in the destination country. Using FlavorCloud ensures that your cost calculations include all of the correct taxes, duties, and fees so that they are paid in full and delivered without additional costs or interruptions.

The Importance of Landed Costs

Understanding all potential costs and fees allows you to set prices and determine processes that maximize the profitability of your business. The true cost of a product goes far beyond inventory and marketing, particularly when you’re a cross-border merchant. Landed costs include the cost of goods sold, insurance fees, freight fees, customs duties, domestic and import taxes, overhead costs, brokerage fees, and shipping fees.

Manually calculating landed costs and taking the time to research various countries to do so accurately is time-consuming, labor-intensive, and potentially risky. Automating these calculations can ultimately save your business time, money, and reputation.
