How we calculate this

Inputs
All values are user-supplied — change MPG, distance and price to match your situation.
Defaults
Pre-filled with average US fuel prices and EPA-style MPG so the page is useful at first load.
Units
US miles, gallons, MPG and USD throughout. No conversions are applied silently.
Rounding
Displayed to the nearest cent or whole mile; internal math keeps full precision.

Sources & assumptions

  • EPA fuel economy dataCity / highway / combined MPG and MPGe baselines.
  • U.S. Department of Energy (fueleconomy.gov)Vehicle efficiency and EV range references.
  • AAA gas price trendsRecent national and regional retail fuel averages.
  • EIA electricity ratesAverage residential per-kWh prices used for EV charging.

We summarize publicly available data — no scraping, no external API calls. Figures are calibrated periodically; use the calculators above for your exact inputs.

Home charging vs. public DC fast charging

Home charging on a typical US residential rate (around $0.15–$0.18 per kWh) is the cheapest way to fuel an EV — usually less than half the per-mile cost of gasoline. Public DC fast chargers run $0.35–$0.55 per kWh, narrowing the gap on road trips.

Why we include charging loss

Charging is never 100% efficient. About 8–15% of the energy drawn from the wall is lost as heat. We add this back to your kWh demand so your real bill matches the result.

Frequently asked questions

What's a typical EV efficiency?

Most modern EVs deliver 3–4 miles per kWh. Smaller, lighter cars can exceed 4 mi/kWh; large trucks may dip below 2.

How do I find my electricity rate?

Check the most recent page of your utility bill. Use the total cost divided by total kWh for a true blended rate including delivery charges.

Is fast charging much more expensive?

Yes — typically 2–3x the cost of home charging. It's still usually cheaper per mile than gas, but the savings shrink.
