Price a trip for gasoline, diesel, E85, LPG, or an electric vehicle, split the cost across passengers, plan refuelling stops, and compare two vehicles side by side.
Change the inputs that matter to your decision. Optional assumptions stay collapsed until you need them.
Enter the one-way distance and choose whether you are coming back.
Switching to electric changes the efficiency and price units to kWh.

CO₂ shown is tailpipe combustion only, or grid emissions for an electric vehicle. It excludes fuel production and delivery. Real consumption varies with terrain, load, speed, weather, and driving style.
Practical notes about the inputs, assumptions, and result.
No. The figure is combustion at the tailpipe, or grid generation for an electric vehicle. Well-to-wheel accounting adds roughly a further 20 to 25% for liquid fuels, and charging losses add to the electric figure.
E85 releases less CO₂ per gallon at the tailpipe and about 65% of that carbon is biogenic, meaning it was recently absorbed by the crop. Because ethanol carries less energy per gallon you also burn more of it, so compare total trip cost as well as the CO₂ line.
The total trip cost is divided evenly by the number of people sharing it. Change the passenger count to see each person's share; the split does not change fuel consumption.
If the second vehicle costs more to buy or rent, the break-even distance is how far you must travel before its lower running cost repays that premium. It is only shown when the second vehicle is genuinely cheaper per mile or kilometre.
The default of 370 g CO₂e/kWh is close to the US average. Use your own region's figure where you know it — a grid dominated by hydro or nuclear can be under 100, while a coal-heavy grid can exceed 700.
