Use the full driving distance
Include the return leg, local driving and planned detours. A one-way map result will understate both fuel and cost for a round trip.

What this estimate does not know
It does not read a live route, traffic, elevation, weather, fuel prices, vehicle load, exchange rates, taxes, fees or availability. Real consumption can differ from the vehicle rating you enter.
Confirm the full driving distance and current prices before leaving. For an electric vehicle, use a charging calculator based on your vehicle, route, charger prices and expected losses instead of treating MPG or L/100 km as an EV estimate.
How the fuel estimate works
Match the units before trusting the total.
For miles, fuel used is total miles divided by MPG. For kilometers, it is total kilometers multiplied by L/100 km and divided by 100. The calculator multiplies that fuel volume by your entered price, then adds the rest of your road-trip budget.
Use realistic fuel efficiency
Choose miles and MPG or kilometers and L/100 km. Highway speed, traffic, weather, elevation and vehicle load can move the real result.
Use a route-wide fuel price
Enter an expected average per gallon or liter, then add tolls and parking separately so the driving subtotal stays understandable.
