Enter the battery efficiency rating in kWh/100 miles and the cost of electricity into the calculator to determine the tesla cost per mile.

Tesla Cost Per Mile Formula

The following equation is used to calculate the Tesla Cost Per Mile .

TCPM = BR/100 * EC

  • Where TCPM is the tesla cost per mile ($/mile)
  • BR is the battery efficiency rating (kWh/100miles)
  • EC is the electricity cost ($/kWh)

The battery efficiency rating can be found in your tesla dashboard and will vary depending on the model you own.

What is the Cost Per Mile of a Tesla?


The cost per mile of a Tesla depends on the efficiency of the car model and the cost of electricity. Using at-home chargers will decrease overall cost, and having a more efficient model will also reduce cost per mile and vice versa.

How to Calculate Tesla Cost Per Mile?

Example Problem:

The following example outlines the steps and information needed to calculate Tesla Cost Per Mile .

First, determine your car’s efficiency per 100 miles. This is based on the model you own and your driving behavior. For this example, the the efficiency is found to be 32 kWH/100 miles.

Next, determine the cost of electricity. In this example, the car is charged at home and the cost of electricity is $.20 /kWh.

Finally, calculate the cost per mile of your Tesla using the formula above:

TCPM = BR * EC * 100

TCPM = 32 kWh/100 miles * .20/kWH

TCPM = $.064 /mile
