EV Electricity Cost per Mile Calculator

Driving an electric vehicle costs a fraction of what gas-powered cars spend per mile — but the exact number depends on your car's efficiency and what you pay for electricity. Enter your vehicle efficiency, electricity rate, charging efficiency, and daily driving miles into the EV Electricity Cost per Mile Calculator to get your EV cost per mile, daily driving cost, and annual driving cost. Add your gas car MPG and gas price per gallon to see your gas cost per mile and annual savings vs. gas.

Frequently Asked Questions

How much does it cost to charge an electric car compared to pumping gas?

On average, EVs cost about half as much per mile to operate compared to gas vehicles. The exact savings depend on local electricity rates, gas prices, and vehicle efficiency.

What factors affect EV charging costs?

Key factors include your local electricity rate, vehicle efficiency (miles per kWh), charging method (home vs public), and charging losses. Home charging is typically much cheaper than DC fast charging.

How do I find my electricity rate per kWh?

Check your utility bill for the rate per kWh. Rates vary by region and can range from $0.10-$0.30+ per kWh. Some utilities offer special EV rates or time-of-use pricing that can reduce costs.

What is vehicle efficiency for electric cars?

Vehicle efficiency for EVs is measured in miles per kWh (mi/kWh). Most modern EVs achieve 3-4 miles per kWh, with some efficient models reaching 5+ mi/kWh.

Is home charging always cheaper than public charging?

Yes, home charging is typically 2-3 times cheaper than public DC fast charging. Level 2 home charging costs are based on your residential electricity rate, while public charging often includes service fees.

How accurate are EV cost calculations?

Calculations provide good estimates, but actual costs may vary based on driving conditions, weather, battery age, and charging habits. Cold weather can reduce efficiency by 10-30%.

What about EV maintenance savings?

Beyond fuel savings, EVs have lower maintenance costs due to fewer moving parts. No oil changes, spark plugs, or transmission repairs are needed, adding to overall savings.
