If you are shipping goods internationally, one of the first questions you will ask is “How is sea freight calculated?” It is a fair question, because unlike a simple courier quote, sea freight pricing rarely comes down to a single flat fee.
In short: it comes down to your shipment’s volume or weight, your chosen shipping method (LCL or FCL) and a set of additional charges layered on top, such as handling, documentation and seasonal surcharges. That’s the short version. Here’s the full breakdown.
What is Sea freight?
Sea freight, also known as ocean freight, is the process of transporting goods by container ship between ports across the world. It is one of the most widely used methods for moving international cargo, particularly for businesses shipping large or heavy consignments where cost efficiency matters more than speed.
The process itself is straightforward in principle. Cargo, whether packaged goods, raw materials or palletised stock, is loaded into containers, which are then carried aboard vessels travelling established shipping routes. Once your goods reach the destination port, they are unloaded and moved on to their final delivery point, either by road, rail or a combination of both. For a full explanation of the terminology used across the shipping process, our shipping glossary is a useful reference point.
Businesses of all sizes rely on ocean freight for its cost-effectiveness over longer distances, especially when shipping in bulk.
Calculating Sea Freight Costs: LCL vs FCL
The first decision that shapes your sea freight pricing is which shipping method you use. There are two main options: Less than Container Load (LCL) and Full Container Load (FCL). Each is calculated differently, and the right choice depends largely on how much you are shipping.
| LCL | FCL | |
| Stands for | Less than Container Load | Full Container Load |
| How it’s priced | Per cubic metre or tonne (whichever is greater) | Flat rate per container |
| Shared space with other shippers? | Yes | No |
| Best suited to | Smaller volumes, infrequent shipments | Larger volumes, long-distance routes |
LCL
LCL stands for Less than Container Load. It is a shipping method where your cargo shares container space with goods belonging to other businesses, rather than filling a container on its own. Instead of paying for an entire container, you only pay for the space your goods actually take up.
LCL costs are typically calculated using a measurement known as weight or measurement (W/M), which takes whichever is greater of your shipment’s cubic volume or its weight in tonnes. Carriers then charge a rate per cubic metre or tonne, alongside handling fees at both origin and destination for consolidating and separating your goods from other shipments in the container. If you are working out your own pallet specifications ahead of a quote, getting this measurement right from the outset will save time later.
It is a practical starting point if you are shipping internationally for the first time, testing a new market, or simply do not have enough cargo yet to fill a container.
FCL
FCL stands for Full Container Load. As the name suggests, this method involves booking an entire container exclusively for your own cargo, whether you fill it completely or not.
FCL pricing works differently from LCL. Rather than being charged per cubic metre or tonne, you pay a flat rate for the container itself. This is generally set according to container size, such as a 20ft or 40ft unit, along with the shipping route and time of year. Because you are not sharing space, there is no consolidation or deconsolidation handling required, which simplifies the overall cost structure too.
It also gives businesses greater control and security over their goods, since the container is not opened or handled by anyone else until it reaches its destination, an advantage that counts for more with higher-value or sensitive cargo.

What Impacts Sea Freight Costs?
Beyond your choice of LCL or FCL, several other factors influence the final price. Getting familiar with these now means fewer surprises when your quote lands.
Shipping Destination
The route between your origin and destination port has a direct impact on cost. Ports with heavier traffic, greater competition between carriers, or shorter distances tend to offer more competitive rates. Less common routes or congested ports, on the other hand, can push prices higher due to limited carrier availability and additional port charges.
Shipment Size
The volume and weight of your cargo are one of the biggest drivers of price. Larger shipments generally benefit from better per-unit rates, particularly with FCL, while smaller consignments are charged proportionally through LCL’s weight or measurement calculation. An accurate measurement of your cargo before requesting a quote avoids discrepancies later on.
Delivery Options
How your goods move once they leave the port also affects the total. A port-to-port service, where you arrange collection and onward delivery yourself, tends to cost less than a door-to-door service, where your freight forwarder manages the entire journey, including inland transport at both ends. Door-to-door adds convenience, but it comes with additional inland haulage charges built into the quote.
Exchange Rates
Ocean freight is typically priced in US dollars, so fluctuations in currency exchange rates can influence what you end up paying. Carriers often apply a currency adjustment to account for movement between the time of booking and the time of payment, so it is worth checking how this is factored into your quote.
Seasonal Demands
Prices rise and fall with demand throughout the year. Peak periods, such as the run-up to major retail seasons or ahead of factory closures in key manufacturing regions, see a surge in bookings, which can push rates up considerably. Shipping outside these peak windows, or booking well in advance, can help secure more favourable pricing.
Cargo Type
Not all cargo is priced the same. Standard, non-hazardous goods are the most straightforward and economical to ship. Dangerous goods, oversized items, or cargo requiring specialist handling, temperature control, or additional documentation typically carry higher rates to reflect the extra care and compliance involved.

FAQs
Is FCL cheaper than LCL?
It depends on your volume. FCL is usually more economical once your cargo is close to filling a container, since you are paying a flat rate rather than a per-unit charge. For smaller shipments, LCL tends to work out cheaper, as you only pay for the space you use rather than an entire container.
How can I get an accurate sea freight quote?
The most accurate quotes come from providing precise details of your cargo’s weight, dimensions and packaging, along with your preferred origin and destination ports and any timescale requirements. This allows your freight forwarder to calculate chargeable weight or volume correctly and account for any specialist handling your goods may need.
Do sea freight costs include customs duties?
Standard sea freight quotes cover transport and handling but not customs duties or import taxes, which are set by the destination country’s authorities. A good freight forwarder will advise you on any duties that apply and can manage customs clearance on your behalf.
