EV Home Charging Cost Calculator (Virginia Electricity Rates)
Estimate your monthly and annual cost to charge your electric vehicle at home using current Virginia residential electricity rates.
Full usable battery capacity of your EV (e.g. Tesla Model 3 Long Range ≈ 75 kWh)
Average efficiency of your EV (typical range: 2.5–4.5 mi/kWh)
Average monthly driving distance (U.S. average ≈ 1,183 miles/month)
Level 2 chargers are typically 85–95% efficient; Level 1 ≈ 80–85%

Formulas Used
Wall kWh per mile = 1 ÷ (EV Efficiency × Charger Efficiency)
Monthly kWh (from wall) = Miles per Month × Wall kWh per Mile
Monthly Cost ($) = Monthly kWh (wall) × Electricity Rate ($/kWh)
Annual Cost ($) = Monthly Cost × 12
Cost per Mile ($) = Monthly Cost ÷ Miles per Month
Full Charge Cost ($) = (Battery Capacity ÷ Charger Efficiency) × Rate
Full Charge Range (miles) = Battery Capacity (kWh) × EV Efficiency (mi/kWh)
Charger efficiency accounts for heat losses during AC-to-DC conversion in the onboard charger.
