Customs & Import Calculators

Free, practical calculators for the numbers behind cross-border trade — import duty, landed cost, customs value, invoice currency conversion, volumetric weight, and container load. Educational estimators for planning a shipment, not legal, tax, or customs-broker advice; always verify duties and rules with the official customs authority.

Import Duty Calculator

Enter a customs value and duty rate to see the duty owed, with an optional VAT/GST layer on top, so you know the tax on a shipment before it lands

Landed Cost Calculator

Add goods, freight, insurance, duty, and clearance fees to get the true total landed cost of an import — and the real cost per unit once everything is counted

Customs Value Calculator

Work out the dutiable customs value of a shipment on an FOB, CFR, or CIF basis from goods, freight, and insurance — the figure the duty rate is actually applied to

Trade Currency Converter

Convert an invoice value at a rate you set, with an optional bank or FX margin, to price an import in your own currency before you commit to the order

Volumetric Weight Calculator

Turn carton dimensions into volumetric (dimensional) weight and compare it with the actual weight to find the chargeable weight a carrier will bill you on

Container Load Calculator

Enter carton size and quantity to see how many fit a 20ft, 40ft, or 40ft high-cube container, the fill percentage, and how many containers a shipment needs
