How to Calculate Freight Charges - Ocean, Air & Road - USA & Europe
How to Calculate Freight Charges for USA and Europe Shipments
Last updated: September 24, 2026 - rate benchmarks from August and September 2026
Knowing how to calculate freight charges saves you from the most common shipping surprise. Two loads with the same weight can land on two very different invoices. Carriers bill on space, mode, distance, and a stack of surcharges - not on weight alone.
As a result, 2026 has made that stack harder to read. On September 17, Drewry's World Container Index rose 1% to $4,500 per 40ft container. Shanghai to New York sat near $9,726, while Shanghai to Rotterdam sat near $3,997.
By the end of this page, you'll know exactly how freight charges are built for ocean, air, and road. You'll see the formula for each mode, how chargeable weight works, and which surcharges sit on top. We price freight every week across our USA and Europe corridors, so this is the method our team actually uses.

The Process
How to Calculate Freight Charges for Ocean, Air, and Road
Every freight quote follows the same structure: a measured load, a base rate, and charges on top. Once you see the structure, the price stops looking random.
What is a freight charge?
A freight charge is the price to move cargo from origin to destination: a base rate plus surcharges and accessorial fees. Quotes use several names for it:
- Freight charge: the core transport cost, based on chargeable weight, volume, or distance.
- Freight fee: often the same thing, or a single line such as a handling or documentation fee.
- Freight delivery charge: the cost of the final leg to the consignee, often a separate line on international moves.
For example, always check which one a quote shows. A low freight charge with a long fee list can cost more than an all-in rate.
Chargeable weight: the number you really pay on
Carriers bill on whichever is higher: the weight on the scale or the space your cargo takes. A pallet of foam and a pallet of steel can fill the same space. Volume therefore gets its own weight value:
- Actual weight: cargo, packaging, and pallet on a certified scale.
- Volumetric weight: a weight calculated from the outer dimensions with a fixed ratio per mode.
- Chargeable weight: the higher of the two - the figure on your invoice.
Express couriers usually divide by 5,000 instead of the airline standard of 6,000. The same box costs more through a courier than through an airline.
The freight charge formula in five steps
Every accurate quote runs through the same five stages, from one pallet to a full container.
Measure and weigh
Record packed length, width, height, and gross weight - pallet included.
Find chargeable weight
Apply the mode ratio, compare with actual weight, and keep the higher.
Apply the base rate
Per kg for air, per W/M or box for ocean, per class or mile for road.
Add surcharges
Fuel, currency, port, and peak-season fees, as a percentage or flat fee.
Add accessorials and customs
Liftgate, residential delivery, storage, duties, and clearance close the price.
In other words, each mode bills in its own unit. Get the unit right and you can estimate any freight charge in minutes.
| Mode | Billing unit | How it works | Best for |
|---|---|---|---|
| Ocean FCL | Per container | Flat rate per 20ft or 40ft box, plus surcharges | Roughly 15 CBM or more |
| Ocean LCL | Per W/M (revenue ton) | Greater of CBM or metric tons x rate | Loads under ~15 CBM |
| Air | Per chargeable kg | Greater of actual or volumetric weight (/ 6,000) x rate | Urgent, high-value cargo |
| Road LTL (USA) | Per hundredweight, by class | Freight class set mainly by density x lane rate | 1 to 6 pallets |
| Road FTL | Per mile or per trip | Distance x per-mile rate + fuel surcharge | Full or dedicated trucks |
| Road groupage (Europe) | Per loading meter | Trailer length used x rate | Part loads on EU corridors |
How to calculate ocean freight charges
For a full container, you pay per box, however full it is. For LCL, the carrier compares cubic meters with metric tons and charges the higher figure. One tonne per CBM is the break-even density in ocean freight.
Worked example - LCL
The base rate moves every week, and the lane matters as much as the mode:
| Spot lane (40ft container) | Drewry WCI - Sep 10, 2026 | Week on week |
|---|---|---|
| Shanghai to New York | $9,726 | +1% |
| Shanghai to Los Angeles | $7,352 | +2% |
| Shanghai to Genoa | $4,216 | -3% |
| Shanghai to Rotterdam | $3,997 | -2% |
Capacity moves the price too. Drewry expects 79 blank sailings out of 721 planned on the major East-West trades between weeks 38 and 42 (Drewry Cancelled Sailings Tracker). For FCL and LCL options, see our Ocean Freight service and our ocean freight transit times from the USA guide.
How to calculate air freight charges
Air freight is where volumetric weight bites hardest. The IATA standard divides length x width x height in centimeters by 6,000. About 167 kg per CBM is the break-even point in air freight.
Worked example - Air
Right-sizing the packaging is the cheapest saving in air freight. For instance, take 20 cm off each pallet height above, and the chargeable weight drops by 64 kg.
Rates stay firm heading into peak season. The Baltic Air Freight Index sat 20.9% above last year on September 21, and jet fuel ran 116.5% higher year on year (TAC Index via Air Cargo News). For time-critical cargo, see our Airfreight service.
How to Calculate Freight Charges for Road Freight
Road freight uses three different logics, depending on load size and region:
- LTL in the USA (freight class): NMFTA moved LTL classification to a 13-tier density scale on July 19, 2025. Freight at 50 pcf or more now rates Class 50 (NMFTA).
- Truckload (per mile): in August 2026, van spot linehaul averaged $2.19 per mile, reefer $2.61, and flatbed $2.70, before fuel (DAT).
- Groupage in Europe (loading meters): one loading meter equals one meter of trailer length. A Euro pallet takes about 0.4 LDM, and a 13.6 m trailer holds 33. See our Road Freight Europe service.

Surcharges and accessorials that change the price
The base rate is rarely the final number. These lines are where most quotes grow:
- Fuel surcharge (BAF / FSC): tracks fuel prices, weekly on road and monthly on ocean.
- Peak season surcharge (PSS): appears when demand spikes, per container or per kg.
- Currency adjustment (CAF): protects the carrier against exchange-rate swings.
- Terminal handling (THC): port charges at origin and at destination.
- Accessorials: liftgate, residential pickup or delivery, inside handling, and storage.
- Customs and duties: clearance fees plus any duties and taxes at destination.
Therefore, ask for an all-in quote that lists every line. It is the only fair way to compare two offers.

Freight Charges Calculated by GreenLine Global - USA and Europe
Overall, we have priced freight across the USA and Europe since 2008. Our team measures, classes, and quotes your shipment right the first time. The price you approve is the price you pay.
What we check before we quote
Real chargeable weight
We check dimensions, density, and packaging before a carrier re-measures.
Every line, up front
Surcharges, accessorials, and customs clearance sit in one all-in quote.
Where we price freight
Cargo waiting between legs can stay in our warehousing network instead of racking up port storage. For corridor detail, see Ocean Freight from the USA and Ocean Freight to Europe.
Heavy equipment and oversized cargo
A standard freight calculator cannot price machinery or oversized cargo. These moves add costs that change with every load:
- Permits: oversize and overweight permits, priced per state or country.
- Trailers: lowboys and RGNs, each with its own rate.
- Escorts and surveys: pilot cars and route surveys, added per move.
For the full process, read our guide to heavy haul loads. For a single engine or motor, see how to ship an engine.
