Frequently Asked Questions

Q

How much does it cost to charge an EV at home?

At average US rates ($0.14/kWh), charging a 75 kWh battery costs about $10.50 for 250+ miles. Annual cost depends on miles driven—typically $500-1000/year for 12,000 miles.

  • A full charge (75 kWh battery) costs $7.50–$15.00 at residential rates of $0.10–$0.20/kWh
  • Level 2 home charger installation costs $500–$2,000 including the EVSE unit and wiring
  • Off-peak/TOU rates can drop to $0.05–$0.08/kWh overnight, cutting costs by 40–60%
  • Federal tax credit of up to $1,000 (30%) is available for home charger installation through 2032
Q

Home vs public charging cost?

Home charging: $0.10-0.20/kWh. Public Level 2: $0.20-0.40/kWh. DC Fast Charging: $0.30-0.50/kWh. Home charging is almost always cheapest—charge at home when possible.

  • Home Level 2 charging averages $0.14/kWh – roughly $0.04/mile for most EVs
  • Public Level 2 (ChargePoint, Blink): $0.20–$0.40/kWh, some charge session fees of $1–$2
  • DC Fast Charging (Tesla Supercharger, Electrify America): $0.30–$0.50/kWh, 3–4× home cost
  • Many workplaces offer free Level 2 charging – equivalent to saving $500–$800/year
Charging TypeCost/kWhCost per Full Charge (75 kWh)
Home Level 1 (120V)$0.10–$0.20$7.50–$15.00
Home Level 2 (240V)$0.10–$0.20$7.50–$15.00
Public Level 2$0.20–$0.40$15.00–$30.00
DC Fast Charging$0.30–$0.50$22.50–$37.50
Q

How does EV compare to gas cost per mile?

EV: ~$0.04-0.05/mile (home charging). Gas (30 MPG, $3.50/gal): ~$0.12/mile. EV costs about 60-70% less per mile. Savings increase with higher gas prices.

  • EV at home rates: $0.04–$0.05/mile vs gas at $3.50/gal (30 MPG): $0.12/mile
  • Annual savings: $700–$1,500/year on fuel alone for 12,000–15,000 miles driven
  • EV maintenance savings add another $500–$800/year (no oil changes, fewer brake replacements)
  • At $5.00/gal gas prices, EV savings jump to $1,200–$2,200/year compared to a 30 MPG car
Q

What is EV efficiency (mi/kWh)?

Efficiency varies by vehicle: compact EVs 4+ mi/kWh, sedans 3-4 mi/kWh, SUVs/trucks 2.5-3.5 mi/kWh. Higher is better. Check your vehicle's EPA rating.

  • Compact EVs (Hyundai Ioniq 6, Tesla Model 3): 4.0–4.4 mi/kWh, most efficient class
  • Midsize sedans (Tesla Model S, BMW i4): 3.2–3.8 mi/kWh, good all-around efficiency
  • SUVs (Tesla Model Y, Ford Mustang Mach-E): 2.8–3.5 mi/kWh depending on trim
  • Trucks (Ford F-150 Lightning, Rivian R1T): 2.0–2.5 mi/kWh, highest cost per mile
  • Cold weather (below 20°F) can reduce efficiency by 20–40% due to battery heating
Vehicle ClassEfficiency (mi/kWh)Cost/Mile (at $0.14/kWh)
Compact EV4.0–4.4$0.032–$0.035
Midsize Sedan3.2–3.8$0.037–$0.044
SUV/Crossover2.8–3.5$0.040–$0.050
Truck2.0–2.5$0.056–$0.070
Q

How long to charge at home?

Level 1 (120V): 3-5 mi/hour. Level 2 (240V): 25-30 mi/hour. DC Fast: 100-200 mi in 30 min. Most people charge overnight with Level 2.

  • Level 1 (120V, 12A): adds 3–5 miles/hour – 40–65 hours for a full charge, fine for PHEVs
  • Level 2 (240V, 32–48A): adds 25–30 miles/hour – full charge in 8–10 hours overnight
  • DC Fast (50–350 kW): adds 100–200 miles in 30 minutes, best for road trips only
  • Most EV owners charge to 80% daily and only go to 100% before long trips (extends battery life)
Q

Does EV charging increase electric bill significantly?

For 12,000 miles/year at average rates, expect $40-80/month increase. Many utilities offer EV rates with cheaper overnight charging to reduce costs further.

  • Average increase: $40–$80/month for 12,000 miles/year at $0.14/kWh national average
  • Time-of-use (TOU) plans can reduce this to $25–$50/month by charging during off-peak hours
  • A 240V Level 2 charger draws 7.2–11.5 kW – similar to running a clothes dryer for 8 hours
  • Some utilities offer separate EV meters with rates as low as $0.05/kWh during midnight–6 AM

kWh/Year = 15,000 / 4.0 = 3,750. All home charging: 3,750 x $0.12 = $450. Gas = (15,000 / 28) x $3.80 = $2,036. Savings = $2,036 - $450 = $1,586 per year.

Formulas Used

Annual kWh Consumption

kWh/Year = Annual Miles / Efficiency (mi/kWh)

Total electricity needed per year based on driving distance and vehicle efficiency.

Where:

Annual Miles= Total miles driven per year
Efficiency= Vehicle efficiency in miles per kWh

Annual EV Charging Cost

EV Cost = (Home kWh x Home Rate) + (Public kWh x Public Rate)

Total annual charging cost split between home and public charging.

Where:

Home kWh= kWh/Year x Home Charging Percentage
Home Rate= Cost per kWh at home (e.g., $0.14)
Public kWh= kWh/Year x (1 - Home Charging Percentage)
Public Rate= Cost per kWh at public chargers (e.g., $0.35)

Annual Savings vs Gasoline

Savings = (Annual Miles / MPG x Gas Price) - EV Charging Cost

Annual fuel cost savings compared to an equivalent gasoline vehicle.

Where:

MPG= Comparable gas car fuel economy
Gas Price= Price per gallon of gasoline
