Home vs Public Charging Costs

Home charging (Level 2, overnight): $0.10-0.20/kWh in most areas, costing $3-6 for a full charge (300 miles). This is equivalent to $0.01-0.04 per mile — dramatically cheaper than gas at $0.10-0.15/mile. DC fast charging (Tesla Supercharger, Electrify America): $0.25-0.50/kWh, costing $15-30 for a full charge. At fast-charging prices, the cost advantage over gas narrows significantly.

Annual Savings: EV vs Gas

At 12,000 miles/year with mostly home charging: EV costs approximately $500-700/year in electricity vs $1,400-2,000 in gas for a 30 MPG car. Annual fuel savings: $700-1,300. Over 10 years of ownership, fuel savings alone total $7,000-13,000 — often enough to offset the higher EV purchase price. Combined with lower maintenance costs, the total cost of ownership for EVs is increasingly competitive with gas vehicles.

⚡ CalcWolf Insight

Installing a Level 2 home charger costs $500-2,000 (equipment + installation) and qualifies for a 30% federal tax credit (up to $1,000). It charges 25-30 miles of range per hour vs 3-5 miles on a standard wall outlet. Most EV owners consider it the single best EV-related investment.

Frequently asked questions
How much does it cost to fully charge a Tesla?
At home ($0.14/kWh): Tesla Model 3 (75 kWh battery) costs about $10.50 for a full charge giving 310 miles of range. At a Supercharger ($0.35/kWh): about $26.25. The home charging cost is equivalent to paying $1.00/gallon of gas in a 30 MPG car.
Is it cheaper to charge at home or at a station?
Home is almost always cheaper — typically 50-70% less than public DC fast charging. Home rates average $0.10-0.18/kWh vs $0.25-0.50/kWh at public stations. Time-of-use electricity plans let you charge overnight at off-peak rates (often $0.06-0.10/kWh) for even greater savings.
