Australia’s registered truck fleet has grown by about 52% since 2011, yet many road transport operators still price work without knowing their true cost of running a truck. The Freight Metrics Truck Operating Cost Calculator addresses that gap: operators enter their own fuel, vehicle, finance, labour, maintenance and operating figures and receive an estimated cost per year, month, day and hour, plus cost per kilometre and per tonne.
This paper explains how the calculator works, what it produces, and what operators should consider when using it. It also sets out the industry context using official data from the Australian Bureau of Statistics (ABS) and the Bureau of Infrastructure and Transport Research Economics (BITRE). Every figure is sourced; where official data does not exist in the form commonly quoted, the paper says so.
Australia had 795,631 registered trucks on 31 January 2025, up from 523,727 on 31 January 2011. The ABS measured the fleet through its Motor Vehicle Census until the final edition in 2021; BITRE now publishes the replacement series, Road Vehicles Australia, from national registry data.
Truck type | 31 Jan 2011 (ABS) | 31 Jan 2025 (BITRE) | Change |
|---|---|---|---|
Light rigid (over 3.5 t to 4.5 t GVM) | 119,539 | 263,193 | +120.2% |
Heavy rigid (over 4.5 t GVM) | 318,223 | 403,870 | +26.9% |
Articulated (prime movers) | 85,965 | 128,568 | +49.6% |
Total trucks | 523,727 | 795,631 | +51.9% |

Two cautions apply. First, the comparison joins two series: BITRE states its scope follows the ABS census as closely as possible, but sources and methods differ slightly. Second, the January 2025 edition is the latest published at the time of writing, so the span is 14 years rather than 15.
The fleet is also ageing. BITRE reports an average age of 16.2 years for heavy rigid trucks and 12.5 years for articulated trucks in 2025, and 122,187 heavy rigid trucks on register were built in 2004 or earlier. Older trucks typically carry higher maintenance costs, which the calculator lets operators model directly.
Articulated trucks do most of the work. The ABS Survey of Motor Vehicle Use (12 months to 30 June 2020) found they performed 77.4% of road freight tonne-kilometres, at an average fuel use of 53.1 litres per 100 km.
The ABS does not publish a single figure for the number of transport businesses that have closed over the past 15 years. Its Counts of Australian Businesses, including Entries and Exits reports exits year by year, with industry detail in downloadable data cubes, and a cumulative total would need to be built from those tables.
What the ABS headline data does show (release of 18 August 2026):
Non-ABS data points to real stress among road freight operators. CreditorWatch data reported by the Australian Institute of Credit Management put the national road transport closure rate at 8.46%, about one in 12 businesses, in the 12 months to 31 October 2025. The same report cites high fuel, maintenance and labour costs, elevated interest rates and fierce price competition. Across all industries, ASIC recorded 14,722 companies entering external administration for the first time in 2024–25, up 33.2% on the prior year.
The common thread is cost. Operators who do not know their cost per kilometre cannot tell whether a rate covers it.
The Truck Operating Cost Calculator is an online tool that estimates what it costs to run a truck or truck-and-trailer combination, using the operator’s own figures rather than industry averages. It is the core of the Freight Metrics road calculator suite, alongside tools for fuel levies, driver wages, maintenance, servicing, carbon emissions and fatigue planning (Freight Metrics, Road calculators).
It is built for owner-drivers, fleet operators, and the bookkeepers and accountants who advise them. Its purpose is simple: know the cost of every kilometre before quoting the next load.
Access works in two tiers:
The operator enters six groups of information: fuel, vehicle, finance, labour, maintenance and operating details. The calculator combines them into a total cost of ownership and operation, then spreads that total across time and across the work the truck performs.
The costs fall into two families, and separating them is the key to accurate pricing.
Cost type | Behaviour | Examples |
|---|---|---|
Fixed (standing) costs | Incurred whether or not the truck moves | Finance repayments, depreciation, registration, insurance |
Variable (running) costs | Rise with every kilometre or hour worked | Fuel, tyres, maintenance and servicing, driver wages on trip-based work |
Once annual totals are known, the unit cost follows. The underlying arithmetic, shown here for cost per kilometre, is:
\text{Cost per km} = \frac{\text{Annual fixed costs} + \text{Annual variable costs}}{\text{Annual kilometres travelled}}The same total, divided by working days, hours or tonnes carried, gives the daily rate, hourly cost and cost per tonne. This is why utilisation matters so much: fixed costs spread over fewer kilometres push the cost of every kilometre up.
The calculator reports estimated costs per year, month, day and hour, together with cost per kilometre and cost per tonne. Because every figure is the operator’s own, changing one input immediately shows its effect on the result.
The calculator does six jobs that matter to a transport business.
The calculator also links to companion tools in the same membership: the Fuel Levy Calculator, a drivers wages calculator based on the long distance drivers award, maintenance and service cost calculators, and a National Driver Work Diary daily sheet planner.

The result is only as good as the figures entered. Operators get the most reliable answer by working through these points.
The calculator produces estimates, not financial, tax or legal advice. Freight Metrics’ disclaimer states use is at the user’s own risk, and operators should confirm major decisions with their accountant or financial adviser.
Australia now has close to 800,000 registered trucks, an ageing heavy fleet and an operating environment where rising costs are pushing operators out of business. In that market, pricing on instinct is a risk few operators can afford.
The Freight Metrics Truck Operating Cost Calculator turns an operator’s own numbers into a clear cost per kilometre, per tonne, per day and per hour. Used with accurate records and reviewed regularly, it gives operators a defensible basis for every quote and a way to test decisions before committing to them.
