How to Use This Tool

  1. Enter your EV's battery capacity (from your owner's manual).
  2. Enter your car's efficiency in miles per kWh.
  3. Enter your electricity rate, then calculate.

EV Charging Cost Formulas

Cost per Full Charge = Battery Capacity (kWh) × Electricity Rate ($/kWh)

Cost per Mile = Electricity Rate ÷ Efficiency (miles per kWh)

Why EVs Are Usually Cheaper to "Fuel" Than Gas Cars

Electricity costs per mile are typically significantly lower than gasoline costs per mile, since electric motors convert energy more efficiently than internal combustion engines, and residential electricity rates (especially off-peak) are often cheaper per unit of energy than gasoline.

Home vs. Public Charging

Home charging on your own electricity rate is usually the cheapest option. Public DC fast charging stations often charge significantly more per kWh than home electricity — factor this in if you rely heavily on public charging.

Finding Your Car's Efficiency

Your EV's efficiency (miles per kWh) is typically shown on your dashboard, in the owner's manual, or on the EPA's fuel economy label for your specific model.

Frequently Asked Questions

Is charging at home cheaper than public charging stations?

Generally yes — home charging uses your standard residential electricity rate, while public DC fast chargers often charge a premium rate, sometimes significantly higher than home electricity costs.

Does cold weather affect my EV's efficiency?

Yes, cold temperatures typically reduce EV efficiency due to battery chemistry effects and cabin heating demands, meaning your real-world cost per mile may be higher than this calculation in winter months.
