Fuel cost calculator
Calculate Your Trip Fuel Cost
Estimate fuel used, fuel cost, cost per mile, and total driving expenses using your own vehicle and price information.
Estimate fuel cost
Enter your distance, vehicle economy, and fuel price. Choose a unit preset before entering values.
Results are estimates based on your entries. Actual fuel use and costs may vary with traffic, weather, vehicle condition, load, driving style, route changes, and fuel prices. No live prices or route distances are used.
How the estimate works
With US units, three steps give a fuel-only estimate:
- Fuel used
- Distance ÷ US MPG
- Fuel cost
- Fuel used × price per US gallon
- Cost per mile
- Fuel cost ÷ distance
For a round trip, double the one-way distance first. UK and metric presets convert the units before calculating.
For example, 100 miles at 25 US MPG uses 4 US gallons. At $3.50 per gallon, estimated fuel cost is $14.00, or $0.14 per mile.
