When this tool is useful
Compare gas and EV energy cost for the same driving distance using miles, EV efficiency, electricity price, gas price, and MPG.
It is designed for planning conversations, not for making a final decision. Enter the numbers that match your location, vehicle, charger access, driving pattern, and season. If a number is uncertain, run a low, middle, and high scenario instead of pretending one estimate is exact.
Gas vs EV comparison
Which scenario has the lower estimated energy cost?
Example scenario
A 900-mile month can look very different if most charging is at home versus mostly at DC fast chargers.
The point is not to copy the example. The point is to see which assumptions drive the result, then replace them with your own electricity rate, fuel price, distance, charging mix, weather, and vehicle efficiency.
Simple cost flow
Common mistakes to avoid
- Comparing one cheap home rate with a gas price from another region.
- Forgetting public charging for trips.
- Treating fuel savings as the same as total ownership savings.
Educational-use disclaimer
These tools are for educational planning only. They use user-entered numbers and editable example assumptions to compare possible EV charging and ownership-cost scenarios. They are not quotes, electrical advice, vehicle recommendations, rebate advice, tax advice, legal advice, insurance advice, financial advice, or recommendations to buy, lease, install, charge, switch, or choose a specific provider.
