    120v standard outlet is most likely what u have in garage ..cost depends on many factors ie ..distance if breaker box to garage ..current capacity of breaker box pic of your box and approximate location to garage

    If possible, have the electrical work done with other work. I was able to add a NEMA 15-50 outlet installed for $250 as part of my solar installation. Going down the list:
    1. Most Expensive Option: Install a Tesla Wall Charger with a 100 A circuit breaker and appropriate conductor size. Future proof for the fastest charging available at home (72 A for Models S & X and 48 A for the Model 3).
    2. Balanced Option: Install a NEMA 15-50 outlet and use the included charging cable for your car. Although the installation instructions suggest a 50 A circuit breaker, the mobile connector included with the Model 3 is limited to 30A. The NEMA 15-50 outlet is universal and can be used for other EV charging solutions.
    3. Economical Option: Use an exisitng 120v standard outlet or get an adapter for any other plug in your garage. For instance, you can use the 30 A electric dryer circuit. At worst case (not recommended) run an extension cord of the appropriate gauge to your car.
    See Tesla's Home charging page for more details.

    Electrical quotes can vary a lot. I would get at least three quotes.

    Installing a 14-50 outlet, as Tesla recommends, can be reasonable when your electrical panel is close to your garage, and has spare capacity for a 50 A breaker and circuit. If that is not the case, then you can save money by installing a 30 A breaker and 14-30 outlet, or even a 20 A breaker and 6-20 outlet. Telsa sells inexpensive UMC adapters for either of these outlets. All three of these options provide 240 V charging.

    I charge both of my Teslas from 20 A 240 V circuits, and they are fast enough for overnight charging. Very high mileage commuters my need a 30 A circuit or better.
