Switchboard Finance logo – GVM glossary definition

GVM

GVM (Gross Vehicle Mass) is the maximum legal loaded weight of a vehicle as specified by the manufacturer. It includes the vehicle’s Tare Weight, driver, passengers, fuel, tools, and full cargo. Lenders use GVM figures when assessing Truck Finance, Vehicle Finance, and Equipment Finance. Relevant blogs: Low Doc Truck Finance Tips, Prime Movers vs Rigids.

Why GVM Matters

GVM determines the maximum legal weight a vehicle can operate at. Exceeding GVM breaches NHVR rules, increases risk, and may void insurance. Lenders review GVM to ensure the asset is appropriate for the borrowing business’s workload through the Tradie Hub, Truckie Hub, and Business Owners Hub.

How GVM Works

  • Set by the vehicle manufacturer.
  • Includes all load, passengers, tools and accessories.
  • Used to calculate Payload: GVM − Tare Weight.
  • Impacts licensing requirements and insurance.
  • Overloading is illegal and increases lender risk.
