Amazon FBA landed cost calculator
What each unit really costs by the time it's sellable at Amazon: the supplier's price plus its share of freight, duty, customs fees, the broker, insurance and inspection, prep and shipping to Amazon. Enter one shipment with up to three products: the calculator splits the shared costs by volume, value or units and gives each product's landed cost per unit.
| Per unit | Product 1 | Product 2 |
|---|---|---|
| Supplier price | $4.20 | $9.80 |
| Freight | $0.69 | $2.31 |
| Duty | $1.05 | $2.45 |
| Customs fees and broker | $0.10 | $0.24 |
| Insurance and inspection | $0.06 | $0.13 |
| Prep and shipping to Amazon | $0.40 | $0.75 |
| Landed cost | $6.50 | $15.68 |
Merchandise processing fee $34.58 (the minimum: 0.3464% of $9,100.00 is $31.52), harbor maintenance fee $11.38 (0.125%, by sea), broker $175.00, shared by value. Freight split by volume. The products fill 222 cubic feet (6.3 m³) before cartons and pallets.
What goes into landed cost
- Supplier price: the unit price on the invoice, in dollars at the rate you paid.
- Freight: everything on the forwarder's bill to get the goods from the factory to your warehouse or prep center: ocean or air freight, origin and destination port charges, trucking.
- Duty: the rate for the product's HTS code in the US tariff schedule plus any extra tariffs on goods from that country, on the price paid to the supplier. Your customs broker can confirm the rate.
- Customs fees: the merchandise processing fee on every entry and, for goods that arrive by sea, the harbor maintenance fee (below), plus the broker's charges.
- Insurance and inspection: cargo insurance, a pre-shipment inspection, lab tests.
- Prep and shipping to Amazon: labeling and bagging, the prep center's fees, shipping into Amazon's warehouses and the inbound placement fee. Amazon's fees once a unit sells (referral, FBA fulfillment, storage) aren't landed cost: they come off each sale, as in the FBA fee calculator.
Splitting freight: by volume, value or units
A forwarder charges a shipment by the space it takes (cubic meters by sea, chargeable weight by air), so freight is usually split by volume: a bulky product carries more of it than a small one, even if they cost the same. Split by value when the products are about the same size, the way duty, customs fees and insurance follow value. Split by units only when every product is about the same size and price.
In the example, a unit of product 2 takes 3.3 times the space of product 1 (480 vs 144 cubic inches), so it carries $2.31 of freight a unit against product 1's $0.69. Split by units, both would carry $1.23 and product 1 would look worse than it is.
US customs fees from October 1, 2026
| Fee | Rate | Applies to |
|---|---|---|
| Merchandise processing fee | 0.3464% of the goods' value, at least $34.58 and at most $670.86 | Every formal entry (goods worth $2,500 or more) |
| Merchandise processing fee, informal entry | $2.77 | Goods under $2,500, filed electronically |
| Harbor maintenance fee | 0.125% of the goods' value | Goods arriving by sea |
The merchandise processing fee's minimum and maximum go up with inflation every October; the figures above are for US Customs' fiscal year 2027 (October 1, 2026 to September 30, 2027).
The example, worked through
Two products in one sea shipment: 1,000 units at $4.20 and 500 units at $9.80, $9,100.00 of goods. Duty at 25% adds $2,275.00. The merchandise processing fee would be $31.52, under the minimum, so it's $34.58; the harbor maintenance fee is $11.38. With $1,850.00 of freight, the broker, insurance, prep and shipping to Amazon, the order lands at $14,340.96: 57.6% more than the supplier invoice. Product 1 costs $6.50 a unit at Amazon, not $4.20; product 2 $15.68, not $9.80.
Landed cost questions
Is duty charged on freight?
Not in the US: duty is on the transaction value, the price paid to the supplier, and international freight and insurance are left out when they're shown separately. Some other countries charge duty on the goods plus freight and insurance.
Why does my landed cost change from order to order?
Freight rates, tariffs and the supplier's price all move, and each shipment mixes products differently. Selling the old batch at the new batch's cost (or the other way round) puts profit in the wrong months: profit is right only when each sale carries the cost of the batch it came from.
What's next once I know it?
