EV Charging Cost Calculator
Estimate your monthly and annual EV charging costs based on your vehicle, electricity rate, and daily driving.
Data last updated: March 2026
The average EV costs $50-80 per month to charge at home, depending on your vehicle efficiency and local electricity rate. At the national average of 16.11¢/kWh, a Tesla Model 3 costs about $9.67 for a full charge providing 272 miles of range — roughly $0.04 per mile compared to $0.13 per mile for a gas car.

How We Calculate EV Charging Costs
This calculator multiplies your vehicle's EPA-rated efficiency (kWh per 100 miles) by your daily mileage to determine energy consumption, then applies your state's residential electricity rate from the U.S. Energy Information Administration (EIA). DC Fast charging uses a 2.5x rate multiplier to reflect typical public station pricing.
Where the Data Comes From
Vehicle efficiency ratings come from the EPA's FuelEconomy.gov database, which tests every EV sold in the U.S. under standardized conditions. Electricity rates are EIA state-level residential averages updated annually. Real-world efficiency varies by 10-20% from EPA ratings depending on driving conditions, temperature, and speed.
Tips for Accuracy
- Check your actual electricity rate on your utility bill — it may differ from the state average, especially if you have a time-of-use plan.
- DC Fast charging rates vary widely by network ($0.25-0.60/kWh). Check your preferred network's pricing.
- Cold weather can increase energy consumption by 30-40%, so winter costs may be noticeably higher.
- Most EV owners charge to 80% daily, not 100%. A full charge estimate assumes you occasionally need maximum range.
