Methodology and Trust
Formulas
Annual Charging Cost
Cost = (Annual Miles / Efficiency) × Average Rate
- • Annual Miles: Total distance driven per year
- • Efficiency: Miles per kWh
- • Average Rate: Weighted average of home and public electricity rates
Gas Savings
Savings = Annual Gas Cost - Annual Charging Cost
- • Annual Gas Cost: (Annual Miles / MPG) × Gas Price
Understanding EV Charging Costs
Key Insights & Concepts
One of the biggest benefits of driving electric is dramatically lower fuel costs. But charging costs vary significantly based on where and how you charge. Understanding these differences can save you hundreds of dollars per year.
Charging Levels Explained
- Level 1 (120V): Standard outlet, 3-5 miles of range per hour. Best for overnight "trickle" charging.
- Level 2 (240V): Home charger or public stations, 25-30 miles per hour. Ideal for daily home charging.
- DC Fast Charging: 100-350 miles in 30-60 minutes. Best for road trips, most expensive option.
Cost Comparison: EV vs Gas
At typical home electricity rates ($0.13/kWh), an efficient EV costs about $0.03-0.04 per mile. A 30 MPG gas car at $3.50/gallon costs about $0.12 per mile—roughly 3-4x more expensive.
The average EV driver saves $800-1,200 per year on fuel compared to a gas vehicle, depending on local electricity and gas prices.
