Fuel Cost Calculator
Enter your trip distance, your vehicle efficiency, and your fuel price per litre. This estimate is for planning only — real-world fuel use varies with speed, traffic, tyre pressure, load, temperature, and driving style.

How it’s calculated
For L/100km, fuel used (L) = distance × (L/100km) ÷ 100. For MPG (US), fuel used is computed in gallons, then converted to litres. Total cost = litres × price per litre.
Planning tip
If you want a safer estimate, add a small buffer (for example 5–10%) for stop-start traffic and hills.
Methods to maximise fuel efficiency
- Avoid harsh acceleration and braking, top tip: many vehicles are at optimal fuel efficiency between 50 and 60 mph.
- Air conditionining should be used in moderation where you can, this is because it adds additional strain on the engine.
- Utilise gears to keep engine RPM low, shift up early to achieve this.
- Regular maintenance including services, oil changes and swapping the air filters to ensure the engine runs efficiently.
- Ensure tyre pressures are maintained at the correct levels reccomended by the OEM, under-inflated tyres increase the rolling resistance making the engine work harder.
- Be sure to avoid idling, and switch off the engine when you can.
