Calculators

Explore focused shipping, customs, and cross-border commerce calculators. Enter your shipment data and verified duty rates to model costs. The calculators provide planning estimates, not binding customs determinations.

Core trade calculators

Updated November 14, 2026. Use these instructions together with current government tariffs and actual shipping quotations.

Choose the calculator for the question you need to answer

Cross-border trade involves several different quantities that should not be mixed. CBM measures shipment volume, CIF combines goods and selected transport costs, customs duty is based on a legal tariff and valuation, and retail pricing measures whether a shipment can support your margin. Our calculators separate these questions so the result can be checked.

For a broad cost estimate, start with the Global Landed Cost Calculator. For a smaller calculation, open the CIF Calculator, Volumetric Weight Calculator, or CBM and LCL Freight Calculator.

Build an import estimate in the right order

Begin with your commercial invoice, detailed product specifications and manufacturing country of origin. Verify the applicable HS or national tariff code and any trade preference conditions. Measure actual packed dimensions and obtain a written freight quote. Confirm the Incoterm and which party is responsible for customs clearance and destination taxes.

Next, calculate freight or CIF, estimate the government charges using the proper tariff and declaration procedure, and include separate brokerage or carrier fees. Sellers can use the DDP vs DAP Pricing Calculator to compare delivery terms and target pricing.

How freight, duties and merchant margins interact

Suppose goods cost $1,000 and freight costs $200. Adding a hypothetical 10% duty to the goods value gives $100 duty in a simplified US example, but that is not the entire landed cost. Insurance, MPF, relevant HMF, brokerage and any special duties may still apply. The complete estimate requires each applicable amount once and only once.

For merchants shipping individual orders internationally, the direct parcel cost may be much higher than a consolidated import followed by local fulfillment. Compare the two using the Parcel vs 3PL Breakeven Calculator. A lower delivery cost does not remove customs duty, inventory financing, return or storage expenses.

Choose regulatory calculators for the destination

For eligible EU low-value e-commerce consignments, use the EU €3 duty and €2 handling fee calculator, which separates IOSS from import VAT payable at entry. The US MPF/HMF calculator models published FY2027 customs processing fees. The India Import Duty Calculator shows BCD, SWS and IGST.

If you need to compare multiple potential US trade measures, use the Section 301 Tariff Scenario Calculator. It does not determine which measures legally stack. Check the full HTSUS and current CBP instructions before entering combined percentages.

Which numbers are estimates rather than verified rates?

A tool can validate arithmetic without knowing the exact duty on a product. We intentionally avoid country-wide duty presets that would imply false accuracy. Zero in an editable tariff field is a blank planning assumption, not a confirmation that the shipment is duty-free.

Every result is only as reliable as the input and the legal scope of its formula. Verify whether VAT or IGST is recoverable, which currency applies, how freight is allocated to multiple SKUs and whether an import fee is already included in the supplier’s delivery quote.

Useful records to keep

Save product specifications, invoices, bills of lading, origin documents, a tariff source dated to the import period, written shipping quotations and the assumptions used for each calculation. Comparing predicted and actual costs helps identify missing broker fees, misclassified goods, or inaccurate packaging dimensions.

Frequently asked questions

Are the tools available without registration?

Yes. The published calculator pages do not require an account.

Do calculator results count as official customs assessments?

No. They are planning estimates and cannot replace legally required customs classification, filings or decisions.

Why do some tariff fields initially show zero?

No verified product-specific duty rate is automatically available for the shipment, so the importer must enter a verified rate.

Can I calculate a mixed shipment?

Calculate separate tariff lines if the products have different duty or VAT treatment, then combine the amounts as appropriate.

How to use these tools

Start with a commercial invoice, freight quote, Incoterm, product HS classification, and destination customs authority. Separate duties from recoverable taxes and keep fees for quotes separate from official government fees.
