Tesla Charging Cost Calculator

Estimate what an EV costs to charge at home each month.

How the Math Works

The Tesla Charging Cost Calculator uses a straightforward formula to determine your charging expenses: cost = miles × Wh/mi ÷ 1000 × price. Here, 'miles' represents the distance you plan to drive, 'Wh/mi' (watt-hours per mile) is your Tesla's energy consumption rate, and 'price' is the cost per kilowatt-hour of electricity. The formula converts watt-hours to kilowatt-hours by dividing by 1000, then multiplies by the electricity rate to yield the total charging cost in dollars.

Practical Applications

To use this calculator practically, first determine your Tesla's Wh/mi rating by checking your energy consumption data in the vehicle or owner's manual. Next, estimate your daily driving distance and find your local electricity rate per kWh (found on your utility bill). Simply input these three values into the calculator to instantly see how much you'll pay to charge your car for your planned journey, helping you budget accurately for your Tesla ownership expenses.

Day-to-Day Use

This calculator empowers Tesla owners to make informed decisions about charging habits and trip planning. By understanding the real cost of charging, you can choose between home charging versus public stations, optimize charging times for lower electricity rates, and factor charging costs into your overall transportation budgeting. It transforms an abstract expense into a concrete, calculable figure that helps you maximize the value of your electric vehicle investment.

Worked example

1,000 mi/mo at 250 Wh/mi → $37.50.
