Who the Trip Cost Calculator is for

Road trippers estimating and splitting the fuel cost of a journey among passengers.

How to use the Trip Cost Calculator

  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

Distance is doubled for a round trip. Fuel used = distance ÷ mpg or distance ÷ 100 × L/100km. Cost = fuel × price, then divided by the number of people.

Budgeting a road trip

A road trip's fuel cost depends on distance, your car's economy, and the pump price — and splitting it between passengers makes it affordable. This calculator combines all of that, including a round-trip toggle, so you can budget the journey and work out a fair share for everyone in the car.
