Fuel Cost Calculator Australia 2026-27
The fuel for a trip, and what it really costs once tolls, running costs and the people in the car are counted — with a grid showing the same trip at other consumption figures and pump prices.
Fuel used is distance times consumption over 100, and the cost is that times the pump price.

How the fuel cost calculator australia 2026-27 works
Fuel used is distance times consumption over 100, and the cost is that times the pump price. Two things move the answer more than people expect. The first is that consumption is not one number: a car uses less on the highway than in traffic, so the highway share you enter adjusts the figure you give by up to a tenth either way. The second is that fuel is not the cost of driving — tyres, servicing, depreciation and insurance are, and the running-cost field is where they go. At twelve cents a kilometre a long trip costs more in wear than in petrol, which is the arithmetic behind every cents-per-kilometre reimbursement scheme. The ATO line is that comparison: 88 cents per kilometre is the 2026-27 rate for claiming car expenses without a logbook, capped at 5,000 business kilometres, and if your real cost per kilometre is below it the rate is working in your favour. Splitting between passengers divides the total, not the fuel — the tolls and the wear are shared too.
Formula: litres = distance × consumption ÷ 100 · fuel = litres × price · total = fuel + tolls + (distance × running cost)
How annual fuel costs are calculated
The fuel cost formula
Annual fuel cost = (Annual km ÷ 100) × Fuel consumption (L/100km) × Fuel price ($/L). For a car using 8.5L/100km, driven 15,000km/year at $2.00/L: (15,000 ÷ 100) × 8.5 × $2.00 = $2,550/year.
| Annual km | Fuel use (L/100km) | Price/L | Annual cost | Weekly cost |
|---|---|---|---|---|
| 10,000 | 7.0 | $2.00 | $1,400 | $27 |
| 15,000 | 8.5 | $2.00 | $2,550 | $49 |
| 20,000 | 8.5 | $2.00 | $3,400 | $65 |
| 15,000 | 11.0 | $2.00 | $3,300 | $63 |
| 20,000 | 11.0 | $2.10 | $4,620 | $89 |
Fuel cost examples by vehicle type — Australia 2025
Based on average fuel prices of $1.90–$2.10/L for ULP and $2.10–$2.30/L for diesel in 2025.
| Vehicle type | Typical L/100km | 15,000km/yr cost | 20,000km/yr cost |
|---|---|---|---|
| Small car (e.g. Toyota Yaris) | 5.5–7.0 | $1,568–$2,100 | $2,090–$2,800 |
| Medium sedan (e.g. Toyota Camry) | 7.5–9.5 | $2,138–$2,850 | $2,850–$3,800 |
| SUV medium (e.g. RAV4 petrol) | 8.5–10.5 | $2,423–$3,150 | $3,230–$4,200 |
| Large SUV/4WD | 11.0–14.0 | $3,135–$4,200 | $4,180–$5,600 |
| Hybrid (e.g. Prius) | 4.0–5.5 | $1,140–$1,650 | $1,520–$2,200 |
| EV (e.g. Tesla Model 3) | 15–20 kWh/100km | $450–$900* | $600–$1,200* |
*EV cost at $0.30/kWh home charging rate. Public fast charging is 2–4× more expensive.
EV vs petrolElectric vehicle vs petrol — true running cost comparison
Energy cost comparison
A petrol car using 8L/100km at $2.00/L costs $1,600 per 10,000km. An EV using 18kWh/100km at $0.30/kWh (home charging) costs $540 per 10,000km — a 66% saving. At public fast charger rates ($0.60–$0.80/kWh), the EV saving narrows to 40–50%.
Total cost of ownership
EVs have lower running costs (fuel, servicing) but higher purchase prices. The break-even point depends on the price premium and annual kilometres. For a $20,000 premium EV: at $1,500/year fuel saving, payback is approximately 13 years. At $2,500/year saving (high-km driver), payback is 8 years. Falling EV prices are reducing this gap rapidly.
Australian EV incentives
FBT exemption: eligible EVs under the luxury car tax threshold (~$89,332) are exempt from fringe benefits tax when provided through a novated lease. This creates significant savings for employees with novated leases. State government rebates (varying by state — check your state government website for current offers).
Saving on fuelHow to reduce your fuel bill — practical strategies
Driving habits (save 10–20%)
Smooth acceleration and braking, maintaining consistent speed on highways, reducing highway speed by 10km/h (saves approximately 10% fuel), turning off engine when stationary for more than 30 seconds, and keeping tyres inflated to recommended pressure.
Vehicle choice (save 30–60%)
Switching from a 10L/100km vehicle to a 6L/100km hybrid saves approximately $1,200/year at 15,000km. Fuel consumption varies more between models than between brands — check Green Vehicle Guide (greenvehicleguide.gov.au) for official consumption figures.
Using petrol price apps
Petrol price cycles in Australian capital cities typically follow a weekly or fortnightly pattern. Prices are lowest mid-week (Tuesday–Wednesday) and highest Friday–Sunday in most cities. Apps like GasBuddy, Motormouth, or state-specific apps show real-time prices across nearby stations.
Commute costTrue cost of commuting by car vs public transport
Full cost of car commuting
Fuel is only one cost of driving. The full cost per kilometre includes fuel, depreciation, insurance, registration, maintenance, and parking. The ATO's 2026-27 car rate is 91 cents/km for income tax deduction purposes — reflecting average total running costs.
| Commute distance | Fuel only (8L/100km) | Full cost (91c/km) | Annual cost (full) |
|---|---|---|---|
| 10km each way | $1,460/yr | $6,424/yr | Full-time commuting |
| 20km each way | $2,920/yr | $12,848/yr | City fringe commuter |
| 30km each way | $4,380/yr | $19,272/yr | Outer suburb commuter |
Public transport comparison
A Sydney Opal weekly cap is $50/week (2025) = $2,600/year for a full-time commuter. An equivalent 20km car commute at full cost is $12,848/year. The car-to-public-transport saving is $10,248/year — before parking costs.

FAQFrequently asked questions
How is annual fuel cost calculated?
Annual fuel cost = (Annual km ÷ 100) × Fuel consumption (L/100km) × Price per litre. For 15,000km/year in a car using 8.5L/100km at $2.00/L: (150) × 8.5 × 2.00 = $2,550.
What is the average fuel consumption of an Australian car?
The average new car sold in Australia consumes approximately 7.5–9.5L/100km on a combined cycle. Large SUVs and 4WDs typically use 10–14L/100km. Hybrids average 4.5–6.0L/100km. EVs are measured in kWh/100km (typically 15–20 kWh/100km).
How much does an EV cost to run compared to petrol?
At home charging rates of $0.25–$0.35/kWh, an EV typically costs $400–$700 per 10,000km versus $1,400–$2,000 for a petrol equivalent — a saving of 55–70%. Public fast charging is significantly more expensive, often 2–4× home rates.
Can I claim fuel costs as a tax deduction?
If you use your car for work purposes (excluding commuting from home to your regular workplace), you can claim a deduction using either the cents-per-kilometre method (91 cents/km up to 5,000km in 2026-27) or the logbook method (actual expenses pro-rated for work use percentage).
What is the cheapest day to buy petrol in Australia?
Petrol prices cycle in most Australian capital cities. Prices typically reach their weekly low mid-week (Tuesday or Wednesday) and peak on weekends. Use apps like GasBuddy, Motormouth, or RACQ/RAA/NRMA price checkers to find the cheapest station near you. Sources
