Landed Cost Formula Explained
Understanding the landed cost formula is essential for accurate import cost estimation. This guide breaks down each component of the formula, explains variations by country, and shows how the pieces fit together.
The Master Formula
Landed Cost =
Goods Value + Shipping + Insurance + Other Fees + Duty + Tax
This formula looks simple, but the complexity lies in calculating the Duty and Tax components correctly. Both depend on intermediate values (customs value, tax base) that vary by destination country.
Breaking Down Each Component
1. Goods Value
The purchase price of your products from the supplier. This is your starting point and typically the largest component of landed cost.
2. Shipping Cost
International freight charges. Includes transport from origin to destination. In CIF countries, shipping is included in the customs value, increasing duty.
3. Insurance
Cargo insurance covering loss or damage. Typically 0.5-2% of goods value. Like shipping, it's included in CIF customs value.
4. Other Fees
Additional costs like brokerage, handling, documentation, port fees, and local delivery. These don't affect duty/tax calculations but are part of total landed cost.
5. Import Duty
Customs duty calculated on the customs value. The rate depends on the product's HS code and country of origin.
CIF countries: Duty = (Goods + Shipping + Insurance) × Duty Rate
FOB countries: Duty = Goods Value × Duty Rate
6. Import Tax (VAT/GST)
Consumption tax on imports. Usually calculated on CIF + duty, creating a "tax on tax" effect.
Most common: Tax = (CIF + Duty) × Tax Rate
Some countries: Tax = CIF × Tax Rate (excluding duty)
Understanding CIF Value
CIF Value =
Goods Value + Shipping Cost + Insurance Cost
CIF (Cost, Insurance, and Freight) is the standard customs value method used by most countries including the UK, EU, Australia, Japan, and most of Asia. When customs officials determine duty, they use the CIF value—not just the goods price.
The US is a notable exception, using FOB (goods value only) for customs valuation. This results in lower duty when shipping costs are high.
Tax Base Variations
The tax base—what VAT/GST is calculated on—varies more than most importers realize. Here are the four common approaches:
| Tax Base | Formula | Used By |
|---|---|---|
| CIF + Duty | (Goods + Ship + Ins + Duty) × Tax% | UK, EU, Australia (most common) |
| CIF Only | (Goods + Ship + Ins) × Tax% | Some countries (less common) |
| Goods + Duty | (Goods + Duty) × Tax% | US sales tax (varies by state) |
| Goods Only | Goods × Tax% | Rare for imports |
Complete Worked Example
Importing electronics to Australia
Goods value:
A$1,500
Shipping:
A$200
Insurance:
A$25
Brokerage:
A$50
Duty rate:
5%
GST rate:
10%
Formula Application:
CIF Value = A$1,500 + A$200 + A$25 = A$1,725
Duty = A$1,725 × 5% = A$86.25
Tax Base = A$1,725 + A$86.25 = A$1,811.25
GST = A$1,811.25 × 10% = A$181.13
Landed Cost = A$1,500 + A$200 + A$25 + A$50 + A$86.25 + A$181.13 = A$2,042.38
Analysis: A$1,500 in goods costs A$2,042.38 landed—a 36% increase. While duty is only 5%, the CIF-based calculation and 10% GST on CIF+duty significantly add to the total.

Practical Tips
Know your country's rules
Before calculating, confirm whether your destination uses CIF or FOB, and what tax base applies. Getting this wrong significantly skews your estimate.
Don't forget the "tax on tax"
VAT on CIF+duty means you're paying tax on the duty amount itself. At 20% VAT and 10% duty, you effectively pay 22% on the duty portion.
Use actual duty rates
Average duty estimates are unreliable. Look up your product's specific HS code to find the actual rate—it could be 0% or 25%.
Include all fees
Brokerage, handling, and delivery are easy to forget but add up. For accurate landed cost, include everything.
When Results Can Vary
- Trade agreements: Preferential duty rates under FTAs change the duty calculation but not the formula structure.
- De minimis thresholds: Below certain values, duty or tax may not apply, effectively setting those terms to zero.
- Customs reassessment: Authorities may adjust declared values, changing the customs value input.
- Special programs: Temporary imports, bonded warehouses, and foreign trade zones modify how/when duties apply.
Key Definitions

Frequently Asked Questions
What is the basic landed cost formula?
Landed Cost = Goods Value + Shipping + Insurance + Other Fees + Import Duty + Import Tax. The complexity comes from calculating duty and tax correctly based on customs value and applicable rates.
Why is the formula different for each country?
Countries differ in how they calculate customs value (CIF vs FOB), what base they use for tax (CIF, CIF+duty, or goods only), and their specific duty and tax rates. The formula structure is the same, but inputs vary.
What is the duty base in the landed cost formula?
The duty base is the value on which import duty is calculated. In CIF countries (most of the world), it's goods + shipping + insurance. In FOB countries (primarily the US), it's just the goods value.
What is the tax base in the landed cost formula?
The tax base is the value on which VAT/GST is calculated. Most commonly, it's CIF + duty, but some countries use CIF only, goods + duty, or goods only. This variation significantly affects total landed cost.
How do I handle the formula for multiple products?
Calculate duty for each product separately (different HS codes have different rates), then sum the duties. For VAT, add all CIF values plus all duties, then apply the single VAT rate. Some countries may have different VAT rates for different product categories.
Does currency affect the landed cost formula?
The formula itself doesn't change, but all values must be in the same currency. Customs authorities convert to local currency using official exchange rates, which may differ from market rates. Factor this into your estimates.
