Fuel Trip Cost Calculator
Pick MPG or L/100km, enter distance and pump price, and see fuel needed plus trip cost. Good for road trips and commute comparisons.
How to Use Fuel Trip Cost Calculator
- Choose US (MPG) or metric (L/100km) mode.
- Enter trip distance and your vehicle’s economy.
- Enter price per gallon or per litre.
- Read fuel needed, trip cost, and cost per mile/km.
Common Use Cases
- Price a weekend road trip before you leave.
- Compare two cars’ fuel cost on the same commute.
Use real economy when you can
Window-sticker MPG is a lab story. If your trip computer says 24 mpg on the commute, use 24. Official US labels live on fueleconomy.gov.
Two unit systems
US mode uses miles and gallons. Metric mode uses kilometres and litres per 100 km — common in the UK, CA, and EU.
Ownership context
Fuel is one line. Loan, insurance, and maintenance bands sit on the Cars hub so you do not budget fuel alone.
