Free fuel cost calculator: estimate trip fuel costs based on distance, fuel consumption rate, and current fuel prices. Plan your road trip budget and compare vehicle efficiency.
Plan your road trip budget with this fuel cost calculator. Enter your trip distance, vehicle fuel consumption, and current fuel price to estimate total fuel cost and volume needed.
Enter the total distance of your trip, your vehicle's average fuel efficiency (e.g., 8 L/100km or 30 MPG), and the current fuel price. The calculator will show the total estimated fuel cost.
L/100km (liters per 100 kilometers) is used in most countries. A lower number means better efficiency. MPG (miles per gallon) is used in the US and UK. A higher number means better efficiency. This calculator supports both units.
For the most accurate estimate, use a blended efficiency that matches your driving conditions. Many cars have different city and highway MPG ratings - you can average them based on your expected driving split.
