GVM & payload calculator

Choose the exact variant and specification edition. Factory figures are estimates: confirm your vehicle plate, modifications and equipment. Grey imports are not included.

Include only the vehicle in your baseline. Keep a note of fuel, occupants and fitted accessories already present. Add only loads absent from that baseline below. Enter the vehicle’s current approved GVM, not a proposed kit rating.

GVM upgrade options appear at 200 kg of remaining payload or less. Choose a larger reserve if you want more room for extra passengers and gear. Lowering this field does not lower the 200 kg reminder.

Plan fuel in litres. The calculator converts it to estimated mass and adjusts only the difference from fuel already in your baseline.

Optional: enter the total capacity of the replacement tank, not extra litres. Leave blank to use the standard tank. Add any change in empty tank weight under Accessories.

Extended tank capacity was cleared for this vehicle selection. Check any retained manual fuel entries against this vehicle.

Confirm the litres present when the vehicle was weighed or its baseline mass was established. Manual and weighbridge entries do not assume an empty or full tank.

Factory selection plans a full tank. Enter actual litres if needed, or clear Planned fuel to apply no fuel adjustment.

Fuel mass uses approximately 0.74 kg/L for petrol or 0.84 kg/L for diesel. Product and temperature vary; this estimate does not confirm vehicle or road approval.

Enter totals in kilograms. Tick “already in baseline” for anything present when the vehicle was weighed. Zero means no additional load in that row.

Use measured ball load. It loads the tow vehicle and is not the trailer’s total mass.
