Make informed decisions about your Tesla with accurate calculators for charging costs, trip planning, battery health, and gas savings. Based on EPA data and real-world driving conditions.
Electric vehicle ownership is fundamentally different from gas cars. Charging costs vary dramatically based on where, when, and how you charge. Our calculators help you understand the true cost of Tesla ownership and maximize your savings.
Electricity is 50-70% cheaper than gasoline per mile. Home charging at $0.15/kWh costs about $0.04 per mile, while gas at $3.50/gallon costs $0.12 per mile in a 30 MPG car.
Annual savings of $1,000-1,500 are typical for drivers covering 15,000 miles per year, even more with Time-of-Use rates or solar panels.
Charging costs vary widely: home Level 2 ($0.10-0.20/kWh), workplace charging (often free), destination chargers ($0.15-0.30/kWh), and Superchargers ($0.25-0.50/kWh).
Strategic charging planning can cut your costs in half. Time-of-Use plans offer rates as low as $0.05-0.08/kWh overnight.
No oil changes, transmission service, spark plugs, or exhaust systems. Regenerative braking extends brake life significantly. Fewer moving parts mean fewer repairs.
Tesla owners save $500-800 annually on maintenance compared to luxury gas vehicles, adding to the total cost advantage.
Comprehensive calculators designed specifically for Tesla owners and prospective buyers. Get accurate estimates based on your specific model, driving habits, and local electricity rates.
Whether you're a daily commuter, apartment dweller, or road trip enthusiast, our calculators help you optimize your charging strategy and maximize savings.
We combine official EPA efficiency data with real-world factors to provide accurate, reliable estimates you can trust for planning and budgeting.
We use official EPA ratings for each Tesla model (Wh/mile) as the baseline. These ratings are tested under controlled conditions and provide a consistent starting point.
Not all electricity from the wall makes it into the battery. We account for conversion losses and thermal management overhead.
Costs are calculated using your electricity rate ($/kWh). We provide U.S. average placeholders, but you should enter your actual utility rate for accurate results.
Bottom line: These calculators provide estimates based on typical conditions. Your actual results will vary by 10-30% depending on the factors above. Use them as a planning tool and adjust inputs to match your specific situation, driving style, and local conditions. For winter driving or sustained highway speeds, increase the Wh/mile input by 20-30% for more accurate estimates.
See how our calculators work with actual scenarios. These examples show typical costs and charging times for common Tesla use cases.
A Model Y Long Range driven 15,000 miles per year with home Level 2 charging at $0.16/kWh, charging from 20% to 80% daily. The Model Y LR has a 75 kWh battery and uses about 280 Wh/mile under normal conditions.
Detailed calculation:
Savings vs gas: A comparable SUV getting 25 MPG at $3.50/gallon would cost $2,100/year - saving $1,353 annually!
Charging a Model 3 Long Range from 10% to 80% at a 150 kW Supercharger. The charging curve means power tapers significantly above 50% SOC. Starting at a higher SOC saves time.
Time and cost breakdown:
Pro tip: Multiple shorter stops (30-70%) are faster than one long stop (10-90%) on road trips due to charging curve taper.
Planning a 500-mile highway trip in a Model 3 Long Range. Highway speeds (75 mph) increase consumption to about 300 Wh/mile. Starting with a full charge (310 mile range), you'll need 2-3 Supercharger stops.
Energy and cost:
Charging strategy:
Weather impact: In cold weather (below 32°F), increase consumption estimate to 360-400 Wh/mile and plan an additional stop or longer charging sessions.
Understanding what affects accuracy and how to optimize your Tesla charging strategy will help you get the most value from these calculators and your vehicle.
