Pick a truck, or type the plate figures yourself. Payload left is the GVM minus the loaded vehicle. If you are towing, the tow-ball down weight counts toward that total.
Tick “I have weighed this vehicle” only if you have a weighbridge ticket. The form then asks for the GVM, GCM and both axle weights. If you have not weighed it, leave that box off and enter the kerb weight and GVM. These figures are a guide. The compliance plate and a weighbridge are the legal record.
Tick this to enter a new GVM, front axle rating, rear axle rating and GCM. Leave a box blank to keep the plate figure.
This vehicle is not in the list. Enter the front and rear axle ratings from the plate. Tick Upgraded GVM if the ratings have been raised, then enter the new figures.
Enter the plate GVM and GCM, plus the front and rear axle weights from the weighbridge. That total is the current weight of the vehicle. Accessories, people and cargo are not added again.
If you know the tow-ball down weight, enter it. If you don't, leave it blank and enter the trailer ATM. The down weight is then taken as 10% of the ATM, and it counts toward GVM.
Tick this if the vehicle was weighed while hitched. Leave it off if the rear axle was weighed without the trailer, and the down weight will be added on top.

A GVM upgrade only changes how much the vehicle itself is allowed to weigh. On its own, it does not raise axle ratings, tyre or wheel ratings, GCM, or how much you can tow. Before you use a higher figure, check that the approved kit is fitted, the second-stage plate is on the vehicle, and the new rating is recorded on the registration.
Everyday Offroad is an approved second-stage manufacturer (SSM) for work done before or after registration, and a federally approved GVM installer. We can raise GVM, GCM and axle ratings in every Australian state. Not every workshop can. To check your vehicle, email info@everydayoffroad.com.au or call 1800 519 700.
NB1 is a GVM of 4,500 kg or less. A normal car licence is enough. NB2 is a GVM over 4,500 kg. You also need a Light Rigid (LR) licence. Each state writes its own rules. In most states the speed limit for these vehicles is 100 km/h, and the alcohol limit is 0.00.
An NB2 vehicle between 4.5 and 12 tonnes usually does not need a National Driver Work Diary, the fatigue logbook. Check your state rules and the NHVR before you assume that. The Northern Territory and Western Australia are not part of the NHVR. Ask the local transport authority there.
This calculator is a guide only. The numbers can be wrong. Talk to the team and have every figure checked before you choose a GVM upgrade, or before you treat a result as legal.
