GVM Calculator

Working out whether your vehicle is legal or overweight can be tricky, there are plenty of hidden traps when it comes to GVM and GCM. With so many different numbers floating around and confusing terminology, the calculations of how to work out GVM and GCM can be difficult or unclear.

To help solve this issue we have created our simple GVM calculator. This is a useful tool to help work out if you are legal by simply entering your vehicles weights and ratings.

Calculate Your Towing Capacity

In addition to specifically GVM, our calculator can help you work out if your touring setup is legal across Australia. This is useful for all types of four wheel drives, trailers and caravans both on and off road.

By using the calculator, you are able to work out your vehicle’s towing capacity in Australia and whether you will be overweight or legal.

The calculator can also be used for checking the weights of your caravan or anything else you are towing.

Common Terms

GVM: Gross Vehicle Mass
BTC: Braked Tow Capacity
GCM: Gross Combined Mass

For a more detailed explanation, please see our comprehensive guide to GVM Upgrades.

Enter Your Vehicle Details

Please Note: All values should be entered as whole numbers only (eg: 1000).

Vehicle Weights

Enter the maximum GVM, BTC and GCM of your vehicle in kilograms so that we can calculate the legal limitations of your vehicle. These figures can generally be found in the owner’s manual or on the compliance plate.

Actual Weights

Enter the current or proposed weights in kilograms of your vehicle, trailer and tow ball download to see if your vehicle will be overweight.
