Truck Running Costs
Running costs decide whether a truck makes money. Over the years you own it they usually add up to more than the price you paid, so it pays to estimate them before you buy and to track them once you do. Here is what to expect and how to keep each cost down.
Fuel
Fuel is the largest running cost for most trucks. Consumption depends on the size of the truck, the weight carried, the terrain, speed, the driver and how well the truck is maintained. A loaded heavy prime mover uses several times the fuel of a light delivery truck. To estimate yours, ask sellers and operators doing similar work, or use the truck's own trip data.
Keeping fuel costs down:
- Driver training and telematics feedback: smooth acceleration, early gear changes and less idling make a measurable difference.
- Correct tyre pressures and wheel alignment.
- Aerodynamic fairings and roof deflectors on highway trucks.
- Regular servicing, including clean air filters and correctly working injectors.
- Fuel cards and planned refuelling in cheaper locations.
Businesses using heavy vehicles (over 4.5 t GVM) on public roads may be able to claim fuel tax credits from the Australian Taxation Office, reduced by the road user charge. Check the current rates with the ATO or your accountant.
AdBlue
Most modern diesel trucks use AdBlue (diesel exhaust fluid) to meet emissions standards. It is consumed at a small percentage of fuel use, so it is a modest but real cost. Buy quality AdBlue from a reliable source: contaminated fluid can damage the emissions system.
Tyres
Tyres are usually the next biggest cost after fuel, especially on multi-axle trucks and trailers. Their life depends on load, road surfaces, pressures, alignment and driving style. Regular pressure checks, rotation, alignment and good quality retreads for drive and trailer positions can cut tyre costs significantly.
Servicing and repairs
- Scheduled servicing: oil, filters and inspections at the manufacturer's intervals. Service plans on new trucks fix this cost.
- Wear items: brakes, clutches, suspension components, batteries and wipers.
- Major repairs: engine, gearbox and diff overhauls on older trucks. Budget for them as a truck ages rather than treating them as surprises.
- Downtime: lost income while the truck is off the road, often the hidden cost of an unreliable truck.

Registration
Heavy vehicle registration charges depend on the vehicle type, its axle configuration and the state or territory. Prime movers for B-doubles and road trains attract the highest charges. Registration may also include compulsory third party (CTP) insurance, depending on the state.
Insurance
Comprehensive insurance for the truck, plus cover for any load (goods in transit), public liability and, for many operators, income protection or business interruption. Premiums depend on the truck's value, use, the driver's record and claims history. A good safety record and modern safety systems can reduce premiums.
Finance
Interest and fees on finance are a cost of running the truck. See our truck finance guide.
Tolls, permits and compliance
Toll roads charge heavy vehicles considerably more than cars. Some operations need permits for route access or oversize loads, and operators may pay for accreditation schemes, fatigue management systems, electronic work diaries and telematics.
Depreciation
Not a cash cost each month, but a real one: the value the truck loses each year you own it. See our truck cost guide for how to factor it in.
Track it per kilometre
Add up all running costs each month and divide by kilometres travelled. Watching cost per kilometre over time shows when a truck is becoming expensive to keep, which is often the right time to sell or replace it. When that time comes, you can list it on Aus Truck Market.
