**About Tesla Cost Per Mile Calculator (Formula)**

The Tesla Cost Per Mile Calculator is a tool that helps Tesla owners estimate the cost of driving their vehicle on a per mile basis. The cost per mile is calculated using two inputs: the battery efficiency rating (BR) and the electricity cost (EC).

The battery efficiency rating is a measure of how many kilowatt hours (kWh) of energy the Tesla consumes to travel 100 miles. The lower the battery efficiency rating, the more efficient the vehicle is, and the less energy it consumes to travel a certain distance.

The electricity cost is the price per kilowatt hour that a Tesla owner pays to charge their vehicle. This cost can vary depending on the time of day, location, and other factors.

**The Tesla Cost Per Mile Formula is:**

**TCPM = BR/100 * EC**

Where TCPM is the Tesla cost per mile ($/mile), BR is the battery efficiency rating (kWh/100miles), and EC is the electricity cost ($/kWh).

By using this formula, Tesla owners can quickly calculate the cost of driving their vehicle on a per mile basis. This information can be useful for budgeting, comparing the cost of driving a Tesla to other vehicles, and understanding the impact of different driving habits on the cost of ownership.
