How It Works

What it actually costs to charge an electric vehicle depends on where you plug in, the electricity rate you pay, and how efficient the charger is. Getting a handle on those costs is what makes budgeting and savings real rather than guesswork. The tool lets you weigh home charging against public stations and decide which habits serve you best.

The formula is Battery Capacity in kWh ÷ Charging Efficiency × Electricity Rate per kWh. The efficiency comes from the charger you pick: 85% for home Level 1 (120V), 90% for home Level 2 (240V) and 80% for DC fast charging, so filling a 75 kWh battery draws about 88, 83 or 94 kWh from the grid. For DC fast charging the calculator also triples the rate you enter to stand in for public-station pricing, so enter your home rate rather than the station's posted price. Estimated range is battery capacity times your miles per kWh, and cost per mile is the charge cost divided by that range.

Time-of-use pricing from your utility is worth building into the math, since shifting charging to off-peak hours can cut costs substantially. Those charging losses are easy to overlook, yet they mean the grid draw always exceeds what your battery stores. Pin down the electricity rate that matches your location and plan, because a wrong rate throws off everything downstream.

Example: 75 kWh Battery on Home Level 2 Charging

  1. 1 Input: Battery Size 75 kWh, Home Level 2 (90% charging efficiency), Electricity Rate $0.1834 per kWh (EIA's U.S. average residential price for June 2026, 18.34 cents) and Efficiency 3.5 miles per kWh.
  2. 2 Energy drawn from the grid: 75 ÷ 0.90 = 83.3 kWh. Cost of a full charge: 83.33 × $0.1834 = $15.28.
  3. 3 Range on that charge: 75 × 3.5 = 263 miles, so the cost per mile is $15.28 ÷ 262.5 = $0.058.
  4. 4 Choosing DC Fast Charging instead: 75 ÷ 0.80 = 93.75 kWh at three times the rate ($0.5502), or $51.58 per full charge and about $0.197 per mile. A 20%-to-80% top-up uses 60% of the battery and costs 60% of these full-charge figures.

Frequently Asked Questions

How much does it cost to charge an electric vehicle at home?
At the U.S. average residential rate of 18.34 cents per kWh (EIA, June 2026), filling a 60 kWh battery from empty on a home Level 2 charger draws about 66.7 kWh at the calculator's 90% efficiency and costs about $12.23. A 20%-to-80% top-up costs about $7.34. Your own utility rate, and any off-peak plan, will move these figures.
Is Level 2 home charging worth the installation cost?
For most daily drivers, yes. The Department of Energy's Alternative Fuels Data Center puts Level 2 at about 25 miles of range per hour of charging, against about 5 miles on a 120V Level 1 outlet, which still adds about 40 miles over an 8-hour night. A typical home Level 2 unit needs a dedicated 40-amp circuit, and whether your electrical panel can take one is the main variable in the installation cost.
How much does public DC fast charging cost?
Prices are set by each charging network and vary by location and charger speed, so check the price shown at the station or in the network's app. This calculator models DC fast charging as three times the electricity rate you enter, at 80% charging efficiency: with an 18.34-cent home rate that is about $0.55 per kWh, or about $41 to fill a 60 kWh battery from empty.
