Fuel Cost Calculator Australia 2026
Calculate the petrol or diesel cost for any road trip, your weekly commute, or annual running costs. Uses current ULP 91 and diesel prices by state, with real-world vehicle presets for common Australian car types. If prices have recently spiked — our petrol at $2.40/L guide shows exactly what that costs different drivers per week. For full scenario benchmarks see the average fuel cost per week guide.
How this calculator works
Enter your state, fuel type (ULP 91 or diesel), vehicle efficiency in L/100km, and weekly or trip distance. The calculator uses the current average retail price for your state — sourced from fuelprice.io and updated regularly — alongside your consumption figure to produce a trip cost, weekly cost, monthly cost, annual cost, and cost per kilometre. Vehicle presets use real-world consumption figures from the Green Vehicle Guide (ADR 81/02 test cycle) adjusted upward by approximately 20% to reflect typical Australian driving conditions. You can override any preset with your own figure.

These state figures are assembled from current official reporting feeds and their public delayed datasets, rather than a manually maintained table. Our Fuel Cost Calculator lets you switch between ULP 91 and Diesel and then apply the price to your own trip distance or annual kilometres.
Live average petrol prices — Australian capital cities
ULP 91 prices across Australian capital cities, updated in real time. Sydney and Melbourne run on price cycles — tracking the cycle and buying at the bottom typically saves $15–$30 per tank compared to buying at the peak:

Annual running costs by vehicle type
The average Australian drives around 15,000 km per year. At current ULP 91 prices (~$1.90/L), annual fuel costs break down roughly like this by vehicle type:
| Vehicle type | L/100km | Annual litres | Annual fuel cost |
|---|---|---|---|
| Small city car (e.g. Yaris, Mazda2) | 6.0 | 900 | $1,710 |
| Medium sedan (e.g. Camry, Mazda3) | 8.0 | 1,200 | $2,280 |
| Hybrid (e.g. RAV4 Hybrid, Corolla Hybrid) | 4.5 | 675 | $1,283 |
| Mid-size SUV (e.g. CX-5, Tucson) | 9.5 | 1,425 | $2,708 |
| Large SUV/4WD (e.g. Prado, Fortuner) | 13.0 | 1,950 | $3,705 |
| Ute (e.g. HiLux, Ranger — diesel) | 10.5 | 1,575 | $2,993 |
Based on 15,000 km/year (BITRE average annual distance) at $1.90/L ULP 91. Diesel row uses an equivalent diesel price; actual diesel prices may differ. Consumption figures are real-world estimates based on Green Vehicle Guide data adjusted ~20% above official test figures. Results vary with driving conditions.
Fuel is a real but not dominant share of what owning a car actually costs. The bigger items are typically depreciation, loan repayments, and insurance. A typical medium car costs $10,000–$15,000 per year all-in — fuel accounts for roughly 20–30% of that. The cost of car ownership calculator puts your fuel figure in context alongside every other running cost.
If you want to reduce the fuel share rather than just measure it, our fuel-saving scenarios guide shows which changes — driving style, tyre pressure, route timing, vehicle choice — are most likely to make a measurable difference.
