Landed Cost Per Unit Calculator

The supplier's price is only the first cost attached to an imported unit. Freight, insurance, duty, import tax, customs user fees, brokerage, and destination charges can turn a profitable-looking purchase into a thin-margin sale. Landed cost gathers the costs needed to bring a shipment to the chosen point in the supply chain, then divides that total across the sellable units.

The boundary of that total must be stated before any arithmetic begins. A buyer-managed shipment usually adds freight and customs costs to the goods value. A CIF or CFR quote generally includes the quoted freight element, so adding the same freight again would double-count it. A DDP quote is intended to include delivery with import duty and tax handled by the seller, but local, marketplace, warehousing, inspection, or exceptional charges may still sit outside the quote. The commercial documents and broker's entry treatment decide what belongs in a real calculation.

Landed-cost uplift and gross margin answer different questions. Uplift compares import additions with the goods cost. Gross margin compares profit with selling price. Markup compares profit with cost. A 30% uplift does not imply a 30% margin, and a price chosen by applying a markup will not necessarily meet a margin target.

Import rates and fee limits can change with fiscal year, tariff classification, origin, trade agreement, entry type, and destination law. Any estimate should be reconciled with the commercial invoice, freight quote, tariff classification, customs valuation, and broker or tax advice before purchase or pricing decisions are final.

How to Use This Tool:

Build the shipment from its commercial boundary outward. The trade terms and duty-and-tax base determine which entered amounts become added costs.

1. Choose Shipment preset and Trade terms, then replace the sample label and values with the actual quote. Use the sellable unit count rather than the supplier's shipped quantity when those differ.
2. Enter Goods unit cost or Total declared goods value, plus freight and insurance. For CIF/CFR or DDP, the freight and insurance fields remain reference amounts and are not added again.
3. Select Duty and tax base and Government fee profile. Enter rates supplied by current destination guidance or a broker. For U.S. formal-entry profiles, verify the merchandise processing fee limits and any exemption before use.
4. Enter brokerage, other fees, selling price, and target gross margin. Keep all money inputs in one currency because the currency selector changes the label, not the values.
5. Review Landed cost per unit, Cost stack, and Margin pressure. Recheck any large customs or fee share, then compare the current selling price with the required price for the chosen margin.

Interpreting Results:

Landed cost per unit is the shipment total divided by sellable units. Add-on per unit isolates the amount above product cost, while Uplift expresses that addition as a percentage of product cost. Use the cost mix to find the largest driver rather than assuming freight is always responsible.

Margin uses the entered selling price before marketplace, payment, advertising, returns, storage, or fulfillment costs. A positive gross margin can therefore coexist with a loss after those omitted costs. The required price only solves the selected landed-cost margin target; it is not a complete retail-pricing recommendation.

The pressure scenarios change one assumption at a time: freight rises 15%, the additional tariff rises 2 percentage points, import tax rises 3 points or starts at 8%, other fees rise by 100 currency units, or units fall 10%. They are sensitivity checks, not forecasts.

Technical Details:

All monetary fields are treated as amounts in a single user-selected currency. The model keeps full numeric precision; ordinary displays format money to two decimals. Unit-cost mode computes goods value from unit cost and unit count, while total-value mode uses the declared shipment value directly.

Formula Core:

The main total adds only the cost layers enabled by the selected trade terms and fee rules.

G is goods value; F and I are added freight and insurance; D is customs duty; T is import tax; and the remaining terms are government, brokerage, and other fees. The unit and margin calculations are:

N is sellable units, P is selling price per unit, and M is gross margin. Target margin is limited to 0% through 95%, so the required-price denominator remains positive.

Rule Core:

Trade terms decide whether entered logistics and customs values are additions. The duty-and-tax model then chooses the bases used for percentage charges.

Brokerage and other fees remain explicit additions in every trade-term model. Enter zero when they are included elsewhere.

Total duty rate is the base duty rate plus any additional tariff rate. For an eligible U.S. formal-entry profile, the merchandise processing fee (MPF) is goods value × MPF rate, constrained to the entered minimum and maximum. The U.S. ocean profile also adds Harbor Maintenance Fee (HMF) as goods value × HMF rate only when transport is ocean. The manual profile adds its percentage of goods value.

Limitations and Compliance Notes:

This is a planning model, not a tariff classifier, customs valuation, tax ruling, or broker entry calculation. It does not determine the Harmonized Tariff Schedule code, origin, trade-agreement eligibility, antidumping or countervailing duty, de minimis treatment, exemption, currency conversion, or destination-specific tax recovery.

• FY2026 U.S. formal-entry MPF defaults are 0.3464% with a $33.58 minimum and $651.50 maximum. These values apply only to eligible entries and should be updated for the relevant fiscal year.
• HMF is modeled only for the U.S. ocean profile and ocean transport. Eligibility still depends on the actual movement and customs treatment.
• The currency selector is a label. Convert every amount, including fee minimums and maximums, before changing it.
• Do not treat the margin result as net profit; downstream selling and operating costs remain outside the calculation.
