Landed cost is not FOB plus freight: the eight-line breakdown

Key Takeaways

• Landed cost typically runs 15-45% above the factory (FOB) price, and most importers' spreadsheets only capture two of the eight lines that make up that gap.
• FOB already includes the supplier's product cost, margin, inland transport to origin port, and export clearance, it is not "just the product price," which is the first place a landed-cost estimate goes wrong.
• VAT is calculated on CIF value plus customs duty, not on CIF alone, so a model that adds duty and VAT as two independent lines on the same base understates the total.
• Commonly missed lines, demurrage, currency conversion fees, quality inspection, and warehouse receiving, are individually small but collectively push a "close enough" estimate meaningfully off actual cost.

A landed-cost estimate built as "FOB price plus a freight quote" is missing six of the eight lines that determine what a shipment actually costs once it clears customs and reaches a warehouse. That gap is why landed cost typically runs 15-45% above the factory price (SeaRates, landed cost guide, retrieved 2026-09-08), a spread wide enough that "FOB plus freight" isn't a rough approximation, it's a different number entirely.

Line 1-2: what FOB already includes, and why freight isn't one number

FOB (Free on Board) is frequently treated as "the product price," but it already bundles the supplier's product cost and margin with inland transport to the origin port and export clearance (SeaRates, retrieved 2026-09-08). Confusing FOB with ex-works pricing is the first place a landed-cost model goes wrong, since it silently assumes origin-side logistics are free.

International freight itself, the actual ocean, air, or road transport cost, is typically the single largest component of total landed cost, and it varies by distance, transport mode, shipment volume, and the Incoterm agreed (SeaRates, retrieved 2026-09-08). Run current freight rates for your specific route and Incoterm through the UAE import landed cost calculator rather than reusing a quote from a previous shipment, since freight is one of the most volatile lines in the whole calculation.

Line 3: insurance, easy to treat as optional, expensive when skipped

Cargo insurance protects against damage, delay, or loss in transit, and while some shipments move without it, that's a risk decision, not a cost-saving that has no downside (SeaRates, retrieved 2026-09-08). Whether or not insurance is purchased, it belongs in the landed-cost model as a deliberate line, priced against the actual risk of the specific route and cargo value, rather than omitted by default.

Line 4-5: duty and VAT are not independent of each other

Import duty is calculated on the customs value of the goods, typically the CIF (cost, insurance, freight) value, which doesn't always match the commercial invoice value exactly (SeaRates, retrieved 2026-09-08). The line most landed-cost models get wrong sits immediately after this: VAT is then calculated on the CIF value plus the customs duty already applied, not on CIF alone, with typical VAT rates ranging 5-27% depending on the destination market (SeaRates, retrieved 2026-09-08). A model treating duty and VAT as two separate percentages applied to the same base understates total tax by the amount of VAT charged on the duty itself, small on a single shipment, compounding at scale.

Line 6: customs clearance and brokerage

Clearance charges, documentation fees, and brokerage services are billed separately from the duty and VAT they help calculate, and they scale with shipment complexity rather than value, a straightforward single-SKU shipment clears more cheaply than a mixed consignment with multiple HS codes, regardless of total value (SeaRates, retrieved 2026-09-08).

Line 7: inland transport at destination

Freight to the destination port is not the end of the journey. Moving goods from the port to a warehouse or final destination is its own line, priced separately from the international freight leg, and is one of the components most often folded incorrectly into a single "freight" estimate rather than budgeted on its own.

Line 8: the fees that don't show up until something goes wrong

The eighth line isn't one fee but a category of commonly overlooked charges: customs examination fees, demurrage and detention charges for containers held past their free time, port congestion surcharges, currency conversion fees, quality inspection costs, and warehouse receiving fees (SeaRates, retrieved 2026-09-08). None of these are guaranteed on every shipment, but a landed-cost model that assumes zero for all of them is modelling the best case, not the expected case, and a business planning margins off the best case is the one most exposed when a shipment gets held for inspection or a container sits past its free days.

Why the eight-line model matters more than the headline percentage

The 15-45% range itself isn't the useful number, it's too wide to price against directly. What matters is which of the eight lines dominate for a specific product and route: a high-value, low-bulk product is duty-and-VAT-dominated, while a bulky, low-value product is freight-and-handling-dominated. Building the full eight-line model once, for a representative shipment, and then updating only the lines that actually move (freight rates, duty classification, FX) is far more reliable than re-deriving a landed cost from scratch on every quote.

Frequently asked questions

Is FOB price the same as ex-works price?

No. FOB already includes the supplier's inland transport to the origin port and export clearance; ex-works excludes both, leaving them for the buyer to arrange. Treating an FOB quote as if it were ex-works, or vice versa, misstates the starting point for the rest of the landed-cost calculation.

Why does VAT come out higher than expected on my landed cost model?

Most likely because VAT is being calculated on CIF value alone rather than CIF value plus customs duty. Since duty is applied first and VAT is calculated on the resulting total, the correct VAT figure is always somewhat higher than CIF value multiplied by the VAT rate on its own.

Which landed-cost line is most likely to be missing from a first-pass estimate?

Usually a combination of destination-side costs: inland transport from port to warehouse, and the "other fees" category (demurrage, inspection, currency conversion). These are individually small but are the lines most consistently left out of a quick FOB-plus-freight estimate.

The bottom line

"FOB plus freight" captures two of the eight lines that make up true landed cost, and the other six, insurance, duty, VAT (correctly calculated on duty-inclusive value), clearance and brokerage, destination inland transport, and the miscellaneous fee category, together account for most of the 15-45% gap between factory price and what a shipment actually costs on the warehouse floor. Build the full breakdown once per product and route, and re-price only the volatile lines going forward. Building that eight-line breakdown into the launch plan for a new import route, rather than treating it as a one-off spreadsheet, is exactly the groundwork covered in the launch logistics and shipping plan for a business setting up its first supply chain.

Figures were verified on 8 September 2026 against published landed cost calculation guides. The specific percentage impact of each line varies significantly by product category, origin, and destination; run your own product and route through a landed cost calculator rather than applying the general range here directly.
