How EV Charging Costs Are Calculated

Your monthly charging cost comes down to four things: how far you drive, how efficient your EV is, where you charge, and what electricity costs there. The calculator follows these steps:

  1. Energy at the battery: monthly miles divided by efficiency (mi/kWh).
  2. Energy from the wall: battery energy divided by charging efficiency (default 90%) to account for conversion losses.
  3. Home/public split: wall energy is split by your home charging share.
  4. Cost: home kWh times your home rate, plus public kWh times the public rate.
  5. Derived figures: yearly cost (monthly × 12), cost per mile, and cost per 100 miles.
  6. Gas comparison: the same miles in a gas car at your gas price and MPG, so you can see the savings.

Example: driving 1,000 miles per month in a Tesla Model Y (4.36 mi/kWh) with 80% home charging at the California average of $0.3361/kWh and 20% public charging at $0.45/kWh costs about $91.46 per month after charging losses.

Average Electricity Prices by State

Residential electricity prices vary widely by state — from $0.127/kWh in Louisiana to $0.480/kWh in Hawaii (EIA, July 2026). Select any state to use its rate in the calculator.

Frequently Asked Questions

How much does it cost to charge an electric car at home?

For most drivers, home charging costs about $40-$90 per month. The exact amount depends on how much you drive, your car efficiency, and your local electricity rate. For example, driving 1,000 miles per month in a Tesla Model Y (4.36 mi/kWh) at the California average rate of $0.3361/kWh costs about $85.65 per month after typical charging losses. Use the calculator above with your state and model for a personalized estimate.

How much does it cost to charge an EV per mile and per 100 miles?

At home electricity rates, most EVs cost about $0.04-$0.09 per mile, or $4-$9 per 100 miles. Public DC fast charging is more expensive, typically $0.10-$0.15 per mile. By comparison, a 30 MPG gas car at $3.50 per gallon costs about $0.12 per mile. Your per-mile cost falls as home charging share increases, which is why the home vs. public mix matters more than the car itself.

Is public charging more expensive than home charging?

Yes, usually by 2-3 times. Home charging uses your residential electricity rate, which averages $0.1831/kWh nationally. Public DC fast charging typically costs $0.30-$0.60/kWh because it includes equipment, demand charges, and network fees. If you charge 80% at home and 20% in public, your blended cost stays close to the home rate; charging mostly in public can erase much of the EV fuel saving.

How long does it take to charge an EV at home?

A Level 1 charger (standard outlet) adds about 3-5 miles of range per hour and suits low-mileage drivers. A Level 2 charger (240V) adds about 25-40 miles per hour, refilling most EVs overnight in 6-10 hours. For a 75 kWh battery, expect roughly 40-60 hours on Level 1 versus 8-11 hours on Level 2 from empty. Most owners charge a few hours nightly rather than from empty.

What is the cheapest time to charge an EV?

The cheapest time is usually overnight, roughly 11 p.m. to 6 a.m., when time-of-use rates are lowest. Many utilities offer off-peak rates 30-50% below peak pricing, and some have dedicated EV plans. Check your utility bill or website for a time-of-use schedule, then set your car or charger to delay charging until off-peak hours. Pairing off-peak charging with a high home-charging share gives the lowest possible per-mile cost.

How much does it cost to install a home EV charger?

Installing a Level 2 home charger typically costs $800-$2,500 in total, including the charger ($300-$700) and electrician labor. Simple installs near the panel sit at the low end; long wiring runs or panel upgrades push costs higher. The national average is around $1,700. Note that the federal 30% residential charging credit expired on June 30, 2026, so do not budget for it. See our installation cost guide for state-by-state figures.
