Common Questions
- How much can I save charging a Tesla instead of buying gas in Austin?
- It depends on how much you drive, your electricity rate, and the gas car you are comparing against. Using typical Austin values (about $0.12 per kWh, 3.5 miles per kWh, a 28 MPG gas car, and roughly $3.65 per gallon), driving 12,000 miles a year usually saves several hundred dollars annually. Adjust the calculator to match your own numbers.
- What gas price and electricity rate does this use?
- The defaults use roughly $3.65 per gallon (near the Texas average reported by AAA) and about $0.12 per kWh (a typical Austin Energy residential rate), as of June 8, 2026. Both are editable so you can enter the prices you actually pay.
- Does this include the price of the car or maintenance?
- No. This calculator compares fuel and charging energy costs only. It does not include purchase price, insurance, registration fees, or maintenance, which vary widely. Treat the result as an energy-cost comparison, not a total cost of ownership.
