How to Calculate FOB Price for Export: A Pricing Guide for Manufacturers

To calculate FOB price, add up everything it costs you to make the product and deliver it onto the ship at the named port of loading, then add your profit margin and a buffer for currency and cost changes. FOB stands for Free On Board, a trade term meaning the seller delivers goods on board the vessel nominated by the buyer at the named port, and the buyer takes on cost and risk from that point. This guide shows how to build an FOB price step by step, with an illustrative example in round numbers, so your export quotes cover your costs and win orders.

What FOB means for export pricing

FOB pricing is common in sea freight because it is simple: the seller handles the product, packing, transport to the port, export clearance and loading; the buyer pays the main sea freight, insurance and import costs. The term belongs to the Incoterms rules, which should always be written with the named port, for example "FOB Lagos" or "FOB Mombasa". For a fuller explanation of how the terms differ, read our guide to Incoterms 2020. Note that FOB is designed for sea and inland waterway transport; for containers, many traders use FCA instead, so check with your forwarder which term suits your shipment.

From ex-works to FOB: what gets added

Ex-works (EXW) price is the price at your factory gate. To convert ex-works to FOB, add the costs of getting the goods loaded on the ship:

• Export packing and palletisation beyond domestic packing.
• Inland transport from factory to the port or container terminal.
• Loading and stuffing the container if needed.
• Export customs clearance and broker fees.
• Port and terminal handling charges at origin.
• Required inspection, testing or certificates.
• Any export-related fees or documentation costs.

Rates for these items vary by country and port, so get written quotes from your forwarder, broker and transporter rather than guessing.

Step 1: Work out your true unit cost for the export price calculation

Start with the cost to produce one unit. Include:

• Materials: raw materials, components and consumables, including waste or scrap.
• Labour: direct wages per unit, plus benefits.
• Overhead: rent, power, maintenance, depreciation, management and administration, shared across units.
• Inner packaging: bags, boxes, labels.

Many factories underestimate overhead. Use last year's total overhead divided by total units produced as a starting point and review it regularly.

Step 2: Add export costs per unit

Gather the export costs for a full shipment, then divide them by the number of units in that shipment. If a 20-foot container holds a certain number of cartons, work out the total cost of inland transport, port charges, documents and loading, then divide by the units inside.

Step 3: Add margin and a risk buffer

Margin is your profit. Decide it as a percentage of the selling price or cost, but be consistent in how you calculate it. Add a buffer if you quote in a foreign currency, if raw material prices move often, or if the quote will stay valid for weeks. A longer validity period needs a larger buffer. Do not hide a low margin by ignoring costs; that only delays the problem.

Illustrative worked example

This example uses round, made-up numbers only to show the method. Suppose you make a plastic storage box and plan to ship 10,000 units in one container, quoted in US dollars.

• Materials per unit: 2.00
• Labour per unit: 0.50
• Overhead per unit: 0.50
• Inner packaging per unit: 0.20

Production cost per unit: 3.20. Total for 10,000 units: 32,000.

Now add export costs for the whole container: export carton upgrade 800, inland transport to port 600, loading 200, export clearance and documents 300, port charges at origin 500. Total: 2,400, or 0.24 per unit.

Cost to place on board: 3.44 per unit. Add a risk buffer of 3 percent of that, about 0.10, giving 3.54. Add a margin of 15 percent on that cost, about 0.53. The FOB price is about 4.07, which you might round to 4.10 per unit.

Your real numbers will differ. The point is the order: production cost, export costs, buffer, margin, then round sensibly. Keep this calculation in a spreadsheet so you can change one number and see the result.

Quote export price clearly

A good quotation states:

1. Product, specification and unit.
2. Quantity and price tiers, if applicable.
3. Trade term and named port, such as "FOB" followed by the port.
4. Currency.
5. Packing details, such as units per carton and cartons per container.
6. Production and delivery lead time.
7. Payment terms.
8. Quote validity, for example 14 or 30 days.

Quantity tiers are a strong tool; see our guide to tiered wholesale pricing for manufacturers. Buyers will compare your quote with others, and our guide for buyers on how to compare supplier quotes side by side shows what they check, so make your quote easy to compare.

Currency and exchange-rate risk

If your costs are in local currency and your price is in US dollars or euros, a change in the exchange rate changes your margin. Ways to manage this include shorter quote validity, a buffer in the price, asking for a deposit when the order is confirmed, and speaking to your bank about forward contracts or other tools. Banks can explain what is available and what it costs for your business.

Common FOB pricing mistakes

• Forgetting overhead, so the margin on paper is not real.
• Using a domestic carton in the quote when export cartons cost more.
• Leaving out inland transport or port charges.
• Quoting FOB without naming the port.
• Giving a long validity period in a volatile market.
• Failing to check that the buyer's forwarder can accept goods at your chosen port.
• Comparing your FOB price with a rival's price that uses a different term.

Keep your costing sheet up to date

An export price calculation is not a one-time job. Raw material prices, freight to the port, wages and exchange rates all change, so review your costing sheet at least every quarter and before each large quotation. Keep a record of which version of the sheet each quote used, so that if a buyer returns weeks later you can see how costs compared at that time. A simple table with one row per cost item, one column for the cost per unit, and one for the source of the number, such as a supplier quote or last month's invoice, makes updates quick. Ask your forwarder to confirm port and loading charges in writing before you send large quotes, and ask your bank what it charges for receiving foreign payments, since that cost can reduce your real margin.

Frequently asked questions

What is the formula for the export pricing formula FOB? Production cost per unit, plus export costs per unit up to loading on board, plus risk buffer, plus margin.

Does FOB include freight? No. Under FOB the buyer pays the main sea freight and insurance. Costs up to loading on the ship are the seller's.

What is the difference between FOB and EXW? With EXW the buyer collects from your factory and handles almost everything. With FOB you deliver goods to the ship and handle export clearance.

Can I use FOB for air freight? FOB is meant for sea and inland waterway transport. For air or multimodal transport other terms are more suitable. Ask your forwarder.

How long should I keep a quote valid? Shorter when costs or exchange rates move quickly. Many suppliers use a period of a few weeks, but choose what protects your margin.

Should I include the buyer's freight in my quote? Only if you sell on CFR or CIF terms. Be sure you can get a real freight quote before offering that.
