Online and retail margins are decided by the costs that are easy to forget: fees, shipping, returns, storage and advertising. Fill in every line, even with an estimate, before deciding what to sell and at what price. Use the worked example below to check the maths against your own figures.
How the Landed Cost Calculator works
Import tax is usually charged on the duty-paid value, so duty compounds into it. Divide by units to get the true cost of each item before pricing it.
Worked example
With the example values (product cost (fob) of $5,000, freight of $600, insurance of $50, customs duty of 10%, import tax / igst / vat of 18%, clearance, port and broker fees of $100, units in the shipment of 100), the landed cost per unit is $74.34; total landed cost $7,433.70, customs duty $565.00, import tax $1,118.70.
