Side-by-side
Compare the same trip in a gas vehicle and an electric vehicle. Change gas price, MPG, electricity price, EV efficiency, charging loss, and road extras to see which option is cheaper.
The difference is the estimated savings for that trip. If the gas trip costs $29.17 and the EV trip costs $14.03, the EV estimate is $15.14 cheaper before any different route or charging-stop considerations.
A useful comparison number is the break-even gas price. That is the gas price where the fuel cost would match the EV charging cost for the same distance. If the break-even price is below your local gas price, the EV trip is cheaper on energy cost. If it is above your local gas price, gas may be cheaper for that specific trip.
Tolls, parking, ferries, and entrance fees usually apply to either vehicle, so the calculator adds the same shared extras to both totals. Gasoline and charging are the vehicle-specific lines that determine the energy-cost winner. If one route requires a charging detour or a different toll road, run that route as a separate scenario rather than forcing unequal routes into one comparison.
This page compares trip cash cost, not ownership. Purchase price, depreciation, insurance, financing, maintenance, and resale value require a different analysis. Keeping those questions separate prevents a cheap single trip from being presented as proof that one vehicle is always cheaper.
Use the price you expect for that trip. Home charging is best for local driving, while road trips often need public charger prices.
No. This page compares trip energy cost only. Insurance, maintenance, depreciation, taxes, and purchase price are separate ownership costs.
