Fuel Cost Calculator
The Fuel Cost Calculator estimates what a trip will cost in fuel from the distance, your vehicle's efficiency, and the local fuel price - supporting km/L, L/100km, and MPG.
Budget any journey
Enter the trip distance, your vehicle's fuel efficiency, and the current price per litre or gallon, and the tool calculates the fuel needed and the total cost. It handles the common efficiency units, so it works whether your car is rated in kilometres per litre, litres per 100 km, or miles per gallon.
Plan and split costs
Use it to budget a road trip, compare the running cost of two routes or vehicles, or work out a fair fuel share for a carpool. Remember real consumption varies with driving style, load, traffic, and terrain, so treat the figure as a close estimate. For the electric-appliance equivalent, see the Electricity Bill Calculator.
Frequently Asked Questions
What fuel efficiency units does it support?
Kilometres per litre, litres per 100 km, and miles per gallon, so you can use whichever your vehicle is rated in.
How is the fuel cost calculated?
It works out the fuel needed for the distance from your efficiency figure, then multiplies by the price per unit.
Why might my real cost differ?
Actual consumption changes with driving style, traffic, load, and terrain, so the result is a close estimate.
Can I use it to split carpool costs?
Yes. Work out the total fuel cost and divide it among passengers for a fair share.
