The supplier's invoice is where the cost starts, not where it ends. This calculator stacks freight, insurance, duty, levies, VAT, clearing and haulage into one honest number — then tells you the landed cost per unit and the price you'd need to sell at for your target margin. Nothing you type is stored or sent anywhere.
The same company behind this calculator runs the freight, clearing and haulage desks that produce these costs — send your figures over and get a binding written quote.
