Calculator Use

This electric car electricity cost calculator is designed to help current and prospective EV owners estimate the financial impact of switching from gasoline to electric power. By inputting your driving habits, vehicle efficiency, and local utility rates, you can generate a precise estimate of your fueling expenses.

Whether you are calculating the cost of a cross-country road trip or trying to budget for your monthly utility bill, this tool provides the data needed to make informed decisions about electric vehicle ownership.

Distance Driven (Miles)
The total number of miles you intend to travel in the selected period (trip, month, or year).
Efficiency (kWh per 100 miles)
This is a standard metric for EV energy consumption. Most modern EVs range between 25 and 40 kWh per 100 miles. You can find this on your vehicle's window sticker or dashboard.
Electricity Price ($ per kWh)
The rate your utility provider charges per kilowatt-hour. The U.S. national average is approximately $0.14 – $0.18, though it varies significantly by state.

How It Works

Calculating the cost of "fueling" an electric vehicle is different from internal combustion engines because we measure energy in kilowatt-hours (kWh) rather than gallons. The electric car electricity cost calculator uses a two-step mathematical process to determine the final price.

Total Cost = (Distance / 100 * Efficiency) * Electricity Rate

  • Energy Consumption: First, we determine how many kWh are required to cover the distance. Since efficiency is usually rated per 100 miles, we divide the distance by 100 and multiply by the vehicle's rating.
  • Cost Conversion: Once we have the total energy in kWh, we multiply it by the local cost per kWh to get the dollar amount.
  • Timeframes: The tool allows you to toggle between trip, month, and annual views to visualize long-term savings.

Calculation Example

Example: Imagine you drive a Tesla Model 3 with an efficiency of 26 kWh/100 miles. You drive roughly 1,200 miles per month, and your electricity rate at home is $0.16 per kWh.

Step-by-step solution:

  1. Distance = 1,200 miles
  2. Efficiency = 26 kWh/100 miles
  3. Rate = $0.16/kWh
  4. Calculate kWh: (1,200 / 100) * 26 = 312 kWh
  5. Calculate Cost: 312 * $0.16 = $49.92
  6. Result: Your monthly "fuel" cost is $49.92.

Common Questions

Is it cheaper to charge an electric car or buy gas?

In almost every scenario, electricity is significantly cheaper than gasoline. While a gas car might cost $0.12 to $0.20 per mile to operate, an electric car typically costs between $0.03 and $0.06 per mile, depending on local energy prices.

How does charging speed affect cost?

Charging speed (Level 1, 2, or DC Fast Charging) does not directly change the amount of energy used, but it can change the price. Home charging (Level 1 or 2) is usually the cheapest, while public DC Fast Chargers often charge a premium for the convenience of speed, sometimes doubling or tripling the cost per kWh.

Does cold weather affect these calculations?

Yes. In cold weather, an EV's efficiency decreases because the battery must be heated and the cabin requires more energy for climate control. During winter, you should increase your "Efficiency (kWh/100mi)" input by 20-30% in the electric car electricity cost calculator for a more accurate seasonal estimate.
