FOB Price: How It Is Calculated and What It Includes

FOB price calculation: start with the goods and add origin costs once

For a purchase from China, use the agreed goods price and reconcile any origin costs not already included. This is a buying worksheet, not an ICC pricing formula: FOB allocates responsibilities rather than prescribing a factory’s selling price, profit margin or invoice breakdown.

Write the contractual basis clearly, for example: FOB Ningbo, Incoterms® 2020. The named port is the port of shipment. FOB applies to sea or inland waterway transport. For the delivery and risk boundary, read what FOB means.

Ask the supplier to mark each cost line as included, separately charged or not applicable. Request enough detail to identify exclusions and compare offers.

A symbolic example without invented prices

Let A be the ex-factory selling price, including the factory’s margin. Let B be inland freight, C export packing, D export declaration and broker fees, E origin terminal handling and loading, and F agreed documentation fees. Each letter represents an order total, not a market price.

The illustrative FOB total is A plus B plus C plus D plus E plus F, provided these are separate, non-overlapping amounts. If A already includes C, do not add C again. If the supplier has bundled several origin services, reconcile that bundle rather than adding its components a second time.

For a unit comparison, divide the reconciled order total by the same agreed quantity. Keep one-off tooling, samples and other separately commissioned work visible alongside the order budget.

What is not included in the FOB price?

Budget separately for main freight from the origin port, any cargo insurance purchased, destination handling, import clearance, applicable duty and import taxes, and delivery to your final address. FOB does not oblige either party to the other to purchase cargo insurance.

Do not treat arrival at the destination port as confirmation of customs clearance or final delivery. Ask for destination charges and inland delivery as explicit quote lines.

For alternative quote boundaries, use the narrow guides to EXW, CIF and DDP. Compare responsibilities with the Incoterms chart before comparing headline prices.

How to compare FOB quotes from different Chinese ports

First match the product specification, agreed quality requirements, quantity, packing, payment terms, currency and readiness date. Confirm that both offers use the same Incoterms edition and include delivery on board.

Next obtain onward freight and destination quotes from each named port to the same final address. Use the same shipment dimensions, weight, service assumptions and quotation period. Compare the combined totals rather than ranking offers by FOB price alone.

For each route, combine the reconciled FOB total with its own freight, insurance purchased, destination services, applicable import taxes and final delivery. Check transit time and sailing availability separately.

Ask the supplier and forwarder to reconcile origin charges together. Where their quotes overlap, agree who pays each charge and how any duplicate amount will be removed before booking.

Use the Incoterms price converter to organise the comparison, using quotations for the actual route rather than assumed freight amounts.

Common hidden extras to resolve before paying

An FOB label with export clearance, necessary origin terminal handling or vessel loading excluded needs clarification. Obtain a corrected price or an explicit contractual variation, identifying its effect on costs and delivery obligations.

Ask whether the packing quote covers the agreed carton specification, pallets, crates and special protection. Check separately requested certificates, document amendments, release services and courier charges.

Request the charging basis for each extra: per shipment, container, document or unit. Establish minimum charges, currency, quotation validity and whether a change in shipment size changes the price.

Agree how storage, failed collection, late cargo, customs examination and vessel changes will be handled. Do not assume that a contingent charge is automatically payable by the buyer: check the applicable obligation and the cause of the cost. Under FOB, buyer notice failures or problems with the nominated vessel can shift costs and risk before loading, subject to the rule’s conditions, including clear identification of the contract goods.

Keep separately commissioned testing, inspections and specification changes visible in the purchase budget. Distinguish them from checking and export formalities already allocated to the seller under FOB; do not add those costs twice.

Landed-cost formula in words

For budgeting, use the reconciled FOB total plus main freight, insurance purchased, destination handling and clearance, applicable duty and import taxes, and transport to the agreed final delivery point. Add separately commissioned product or sourcing work where relevant, counting every charge once.

Record cash requirements and any recoverable taxes separately. This budgeting worksheet is not a universal customs-valuation formula: check the destination’s valuation rules.

For EU imports, the European Commission identifies transaction value as the main customs-valuation method, subject to required additions and deductions. US CBP excludes qualifying international freight and insurance costs from transaction value; deductions for amounts included in the price must be supported by actual costs rather than estimates. Confirm the treatment and evidence for your shipment with the destination customs authority or customs agent.

UK worked example: FOB is not automatically the customs or VAT value

For a sea import into Great Britain using transaction value, start with the price paid or payable and make the required customs adjustments. Include relevant transport, insurance, loading and handling costs to the UK border where not already included. Other adjustments may apply; do not use the FOB invoice alone as the completed customs valuation.

For import VAT, start with the customs value even if no duty is payable. Add applicable Customs Duty, excise duty and other import charges, excluding the import VAT itself, plus required incidental expenses to the first UK destination and those arising from transport to a further UK destination known at importation. Do not count amounts already included twice.

Use the customs value builder to organise supporting amounts, then check the declaration basis with your customs agent. Do not copy this Great Britain example into a calculation for another destination.

Check your supplier’s FOB quote before committing

Use the China supplier quote checker with the complete quote, named port, product specification, quantity and packing details. Resolve unclear origin charges before comparing the offer with another supplier.

Bring supplier and freight quotations together for review. Ask the reviewer to identify gaps and overlaps, and agree the scope and deliverables before commissioning work.
