How EV Home Charging Costs Are Calculated

Home charging cost depends on your EV's efficiency (miles per kWh), how many miles you drive, and your local electricity rate.

Monthly kWh Needed = Monthly Miles ÷ EV Efficiency (miles/kWh)
Monthly Charging Cost = Monthly kWh × Electricity Rate ($/kWh)
Cost Per Mile = Electricity Rate ÷ EV Efficiency
Annual Savings vs Gas = (Monthly Miles ÷ MPG × Gas Price) − Monthly Charging Cost) × 12

Average EV efficiency: 3–4 miles/kWh. Tesla Model 3: 4.1 miles/kWh. Chevy Bolt: 3.9 miles/kWh. Ford F-150 Lightning: 2.2 miles/kWh. US avg electricity rate 2026: $0.16/kWh.

Real-World Scenario Example

"Tesla Model 3 (4.1 mi/kWh) driving 1,000 miles/month at $0.16/kWh: 244 kWh needed × $0.16 = $39/month vs. $120/month for a 30 MPG car at $4/gallon gas."

Inputs
