How to Calculate Truck Payload

GVW minus tare weight equals your legal payload. Get the formula right — once per load, before the truck leaves the dock.

How to calculate truck payload in 6 steps

Follow this sequence every time you plan a load — weight violations at weigh stations or border crossings mean fines, delays, and out-of-service orders.

Step 1

Find the legal GVW limit for your route

GVW limits vary by country and vehicle type. The EU standard for a 5-axle articulated combination (3-axle tractor + 2-axle semi-trailer) is 40,000 kg. The US federal limit for the same configuration is 80,000 lbs (36,287 kg). For intermodal transport in the EU (road + rail or short-sea leg), the limit rises to 44,000 kg. Some countries apply stricter limits on secondary roads or during seasonal spring thaw — always check every country on your route, not just the destination.

Step 2

Get the tare weight from the vehicle documents

Tare weight is the weight of the empty vehicle — tractor plus trailer. You'll find it on the Certificate of Conformity (CoC) or the vehicle registration document. Typical EU tractor tare: 7,500–9,500 kg. Typical EU curtainsider trailer tare: 6,500–8,500 kg. Total tare is commonly 14,000–18,000 kg. Do not use average or estimated values — get the actual figure from the documents, as different specs (liftaxles, refrigeration units, tail lifts) change tare weight significantly.

Step 3

Calculate net payload: GVW minus total tare

The formula is simple: Net Payload = GVW − Total Tare. For a standard EU 5-axle combination: 40,000 kg − 16,000 kg = 24,000 kg payload. For a US 5-axle: 80,000 lbs − 29,500 lbs = 50,500 lbs (22,906 kg). This is your maximum legal cargo weight. Remember that fuel, driver, and any equipment loaded on the truck (straps, load bars, pallets) all count toward tare — they reduce your available payload.

Step 4

Apply a safety margin of 3–5%

Scales are never 100% accurate, and cargo weight declarations from shippers are sometimes underestimated. A 3–5% safety margin on net payload protects you from accidental overloads. At 5%: EU 24,000 kg × 0.95 = 22,800 kg working payload. Never load to the exact legal limit — one wet pallet or a heavier-than-declared cargo can push you over. Many experienced operators use 23,000 kg as a working limit for a standard EU curtainsider.

Step 5

Check individual axle limits — total GVW is not enough

Even if total GVW is within the limit, each axle group must be within its own legal limit. EU axle limits: steer axle 7,500 kg, drive tandem 19,000 kg, trailer bogie 21,000 kg. US limits: steer 12,000 lbs, drive tandem 34,000 lbs, trailer tandem 34,000 lbs. Cargo position within the trailer determines how weight is distributed across axles. Heavy cargo loaded too far forward or rearward will overload one axle group even when total weight is legal. Always verify axle loads from load positioning, not just total weight.

Step 6

Record the payload on your transport documents

Cargo weight must be declared on the CMR waybill (EU international), Bill of Lading, or relevant national transport document. The declared weight is a legal declaration — signing a CMR with an underweight declaration to stay under a limit is fraud. If the shipper provides an incorrect weight declaration, the carrier still bears operational responsibility for the vehicle weight at weigh stations. Request a verified cargo weight certificate from the shipper for high-density or bulk loads.

These are federal/directive-level limits. Individual roads, bridges, and seasonal restrictions can be lower — always verify for your specific route.

EU intermodal bonus

+4,000 kg (44,000 kg GVW)

Truck combinations carrying ISO containers or swap bodies as part of a combined road + rail or road + short-sea transport chain qualify for a 44,000 kg GVW allowance under EC Directive 96/53. The road leg must be part of a documented intermodal chain. This gives approximately 28,000 kg payload for a standard EU tare — useful for heavy container inland haulage.

Seasonal weight restrictions

80–90% of normal limits

Several EU countries (Poland, Lithuania, Latvia, Estonia, parts of Scandinavia) reduce permitted axle loads by 10–20% during spring thaw (typically March–May) to protect road surfaces. Some Nordic countries apply seasonal restrictions year-round on specific roads. If your route passes through affected countries during thaw season, your effective legal payload drops significantly — plan accordingly or route around restricted roads.

Overweight fines

€500 – €10,000+

Overweight fines vary widely by country and degree of excess. Germany: up to €5,000 for the driver, up to €25,000 for the company. France: up to €15,000. UK: unlimited fixed penalty per axle group. US: fines per pound over limit, compounded by state. In many jurisdictions the load must be offloaded at the point of detection and cannot continue until weight is reduced — this adds delay costs on top of the fine.
