A tariff isn't just a rate — it becomes a per-unit cost and, if you can't raise prices, a margin problem. This tool computes the true landed cost of an import shipment and shows exactly what a duty does to your unit economics, so you can decide whether to reprice, resource, or absorb it.

How landed cost is built up

Landed cost is the all-in cost to get goods to your door: the supplier's product cost, plus import duty, freight, insurance, a customs broker fee, and government fees like the Merchandise Processing Fee and Harbor Maintenance Fee. Non-product costs routinely add 20–40% on top of the invoice price, so pricing off the supplier invoice alone quietly understates your real cost and inflates the margin you think you are earning.

Duty is charged on the customs value. On an FOB basis that value is the product cost alone; on a CIF basis it also includes freight and insurance, which widens the base and raises the duty. This calculator lets you pick the basis and enter the rate directly — it deliberately does not hardcode a duty schedule, because rates change frequently with trade policy and depend on your product's HTS classification and its country of origin. Enter the current rate, and the tool assembles every component into a single landed cost and a true per-unit figure you can price against.

What the tariff does to your margin

The tariff lands as extra cost on every unit, so your gross margin shrinks unless you raise price. The calculator shows gross margin before and after the tariff at your current selling price, alongside the break-even price that would restore your pre-tariff margin. At a $45 selling price on goods that were landing near $23 a unit, a 25% duty can pull margin down by roughly ten points — real money once you multiply it across a full shipment.

You then have three levers: raise price to the break-even figure and pass the tariff to customers, absorb it and accept the thinner margin, or cut cost elsewhere in the landed stack. That is why a new duty so often triggers a scramble to resource to a lower-tariff country of origin, renegotiate supplier pricing, or re-engineer the freight and fee stack — the tariff turns straight into a pricing and sourcing decision, and this tool quantifies exactly how big that decision is before you make it.

Limits and what to verify

This is a planning estimate, not a customs entry. It does not classify your product, look up the current rate, or model anti-dumping and countervailing duties, duty drawback, foreign-trade-zone treatment, or de-minimis rules — you enter the rate and fees yourself, which is exactly what keeps the tool accurate as policy shifts underneath it. Your actual duty depends on the correct HTS code and the declared country of origin, and both the rate and the fee structure can change on short notice.

Treat the output as a fast way to test a scenario and price around a duty, then confirm the specifics before you commit money to an order. Verify your classification, current rate, and applicable fees with U.S. Customs and Border Protection (CBP) or a licensed customs broker, and re-run the numbers whenever a new tariff action, exclusion, or surcharge lands so your landed cost and pricing always reflect the rules in force today.
