EV trip cost formula

EV cost = miles x kWh per mile x electricity price x charging-loss adjustment

For a 250-mile trip in an EV rated at 30 kWh per 100 miles, base energy use is about 75 kWh. With 10% charging loss and electricity at $0.17/kWh, the trip costs about $14.03.

What to enter

  • Trip distance: planned miles or kilometers.
  • EV efficiency: kWh per 100 miles or kWh per 100 km.
  • Electricity price: home, workplace, hotel, or public charger price.
  • Charging loss: use 5% to 15% if you do not know the exact value.

Home charging vs public charging

EV trip estimates change quickly when the charging price changes. Home charging is often the cheapest assumption, while DC fast charging can be much higher. For road trips, use the price you expect at public chargers, not only your home electricity rate.

To compare fairly with gasoline, include the same road extras on both sides: tolls, parking, ferry fees, and any route-specific charges.

EV trip cost FAQ

What kWh per 100 miles should I use?

Use your vehicle dashboard average, EPA efficiency, or a conservative estimate from recent similar trips. Cold weather and high speed usually increase energy use.

Does the calculator include charging time?

No. This page estimates energy cost, not stop time. Use route-planning tools for charger stops and charging duration.
