How To Calculate GVW of Truck and Trailer

If you are in the trucking business, then you know how important it is to stay within the GVW limits of your vehicle. But do you know how to calculate the GVW of a truck and trailer? It’s not as difficult as you might think!

The trucking industry has its own language, and one of the most important terms for drivers to know is “GVWR.” GVWR stands for “Gross Vehicle Weight Rating.” The GVW in trucks is your vehicle’s maximum weight when it’s fully loaded. This includes the truck’s weight and any cargo, passengers, or fuel. The GVWR is different for every truck, so it’s important to know what yours is before you start driving. However, how is GVW determined? You can usually find the GVWR on a sticker inside the driver’s door.

The other two weights that are related to the GVWR are the tare weight and the rated payload. The tare weight is simply the weight of the empty truck. The rated payload is the amount of weight that your truck can safely carry, and it is calculated by subtracting the tare weight from the GVWR.

For example, if your truck has a GVWR of 10,000 pounds and a tare weight of 4,000 pounds, your rated payload would be 6,000. Keep in mind that these weights can vary depending on how your truck is configured, so always check with your manufacturer or dealer before you start driving.

Knowing how to calculate how much weight a truck can carry is vital because it will help you determine if your truck can handle the weight of the load you are planning to carry.

Is GVWR and Towing Capacity the Same?

GVWR is the maximum weight capacity of a vehicle without a trailer attached. Towing capacity, on the other hand, is the maximum weight capacity of the vehicle, specifically in terms of how heavy of a trailer it can tow. However, GVWR and towing capacity are not always the same. The towing capacity of a vehicle will be lower than its GVWR if it is not designed to tow trailers.

Conversely, the towing capacity of a vehicle will be higher than its GVWR if the vehicle is designed specifically for towing. As such, it is important to consult your owner’s manual or dealer when determining how much weight your vehicle can safely carry or tow.

How Is a Truck’s Gross Vehicle Weight GVW Determined?

A truck’s gross vehicle weight rating (GVWR) is the maximum allowable weight of the vehicle itself, plus its maximum payload in terms of passengers, cargo and accessories within the cab or bed. It excludes any weight towed behind the vehicle on a trailer. The manufacturer determines the GVWR, and is usually prominently displayed on the truck’s door placard or sticker.

It’s important to note that the GVWR includes the weight of the vehicle’s fuel, so it’s important to account for that when determining how much payload the truck can carry. The GVWR also takes into account the weight of any optional equipment that may be installed on the truck, such as a bull bar or snowplow. If you’re unsure about a truck’s GVWR, you can consult the owner’s manual or contact the manufacturer directly.

What Is the Weight of a Truck and Trailer?

The weight of empty semi truck and trailer can exceed 35,000 pounds. When fully loaded, these trucks can weigh up to 20% more. Large trucks like these are more likely to be involved in serious accidents than passenger vehicles due to their size and weight. But it can vary depending on what the truck is carrying. A fully loaded tractor-trailer typically weighs about 80,000 pounds. However, a semi-pulling empty trailer only weighs around 35,000 pounds. When a tractor-trailer is carrying a load, it can take 20% – 40% more distance to stop than cars do.

This means that it takes the length of two football fields for a loaded tractor-trailer to come to a stop. Truck drivers must be aware of this and drive accordingly. By being aware of the weight of their truck and trailer, they can help to ensure their safety of themselves and those around them.

What Does 7000 GVWR Mean on a Trailer?

If you have seen a weight sticker on the side of a trailer, RV, or other vehicle, you may have wondered what it meant. These stickers typically list the gross vehicle weight rating or GVWR. Simply put, GVWR is the maximum weight that a vehicle is designed to carry. This includes the weight of the vehicle itself, as well as any passengers or cargo. Exceeding the GVWR can cause serious damage to the vehicle and put occupants at risk.

For this reason, it is important to know your GVWR and ensure you do not exceed it. So, how is GVWR determined? The answer is actually quite simple. The manufacturer of the vehicle takes into account the weight of the vehicle itself, as well as the maximum weight capacity of the axles and tires. With this information, they are able to calculate the maximum safe weight for the entire vehicle.

When shopping for a new vehicle, be sure to pay attention to the GVWR sticker so that you can choose a model that meets your needs. And if you ever have any doubts about whether or not your vehicle is safely loaded, always err on the side of caution and consult a professional.

What Is the Difference Between GVW and GVWR?

Though a truck’s GVW is influenced by its GAWRs, the two aren’t one and the same. A truck’s GVWR is the maximum weight rating established by the chassis manufacturer. On the other hand, GVW is the truck’s total weight and payload at a point in time. It’s important not to exceed either rating, as doing so can cause major damage to your truck.

When calculating GVW, be sure to consider factors like the weight of any passengers, fuel, and aftermarket additions such as a bull bar or snow plow. Though it may be tempting to overload your truck to maximize its hauling capacity, it’s simply not worth the risk. Play it safe by sticking to the manufacturer-established weight limit.


Calculating the GVW of your truck and trailer is important for several reasons. Not only does it help to ensure your safety on the road, but it also helps to prevent damage to your vehicle. Be sure to consult your owner’s manual or the manufacturer if you ever have any doubts about your truck’s GVWR. And always err on the side of caution when loading your truck to avoid exceeding either the GVW or GVWR.
