It depends on individual circumstances. If you are able to charge a Tesla Model 3 with inexpensive renewable energy or have access to free charging, then the ownership costs may be cheaper compared to fuel costs for a comparable gasoline-powered car. However, the upfront cost of purchasing a Tesla Model 3 is more expensive than many other cars. In addition, other associated costs like insurance, repairs, and maintenance may also impact the ownership cost. Overall, the costs of owning a Tesla Model 3 will vary widely depending on individual circumstances.
