Estimate fuel and road-trip cost
Estimates use the figures you provide. Actual consumption can vary with traffic, weather, load, terrain, tyre pressure and driving style.
Plan with clear assumptions
Compare travel costs before you leave
Use your own vehicle efficiency and local energy price, then include the real extras that generic estimates often miss.
Model EV losses
Separate energy delivered to the vehicle from energy purchased at the charger.
Split the total fairly
Add tolls and parking, then divide the complete trip cost between travellers.
Method, example and limitations
Understand the result before using it
Use the trip calculator to estimate variable journey costs from distance, vehicle consumption and the price paid for fuel or charging. Add tolls, parking and other trip-specific costs separately so the energy estimate remains understandable.
What the tool does
For litres per 100 kilometres, fuel used equals distance multiplied by consumption and divided by 100. EV energy uses distance multiplied by kWh per 100 kilometres and divided by 100. The tool then multiplies energy by the entered unit price, adds extras and divides the total by the number of travellers when requested.
420 km petrol trip shared by three people
- At 7.5 L/100 km, estimated fuel use is 31.5 litres.
- At $1.90/L, fuel costs $59.85.
- Add $35 of tolls: $94.85 total, or about $31.62 each.
How to read it: This is a planning estimate. Traffic, speed, weather, towing, tyre pressure, detours and charging losses can materially change actual consumption.
- Distance and consumption use compatible units.
- The entered unit price applies to all modelled energy.
- Per-person splitting is equal and does not allocate different expenses to individuals.
- Entering miles with a litres-per-100-kilometres figure.
- Using a dashboard’s best-case consumption for a loaded road trip.
- Ignoring charging losses or paid parking when comparing an EV with fuel.
