How We Calculate Your Tesla Savings
Our Tesla Savings Calculator compares the estimated energy cost of driving a gasoline vehicle with the electricity cost of driving a Tesla over the same distance. Use your own mileage, gas price, electricity rate, and vehicle efficiency for a more useful estimate.
Divide your annual miles by the gasoline vehicle's miles per gallon (MPG), then multiply by the price of gas.
Annual gas cost = (annual miles ÷ gas MPG) × gas price per gallonDivide annual mileage by your Tesla's efficiency in miles per kilowatt-hour (mi/kWh), then multiply by the electricity rate.
Annual Tesla energy cost = (annual miles ÷ Tesla mi/kWh) × electricity price per kWhIf your efficiency figure measures energy used while driving rather than energy purchased at the outlet, real charging costs may be higher due to charging losses.
Subtract estimated Tesla electricity costs from estimated gasoline costs.
Annual energy savings = annual gas cost − annual Tesla electricity costMultiply annual savings by five for a simple five-year illustration. This assumes prices, mileage, and efficiency stay the same.
Five-year energy savings = annual energy savings × 5What this estimate covers: Gasoline versus electricity expenses only. It does not include purchase price, depreciation, financing, insurance, maintenance, tires, registration, charging equipment, or taxes. Actual results depend on driving conditions and charging habits.

Realistic Tesla Savings Scenarios
These are illustrative scenarios, not verified national averages or promises of savings. The examples use a hypothetical $3.50/gallon gas price and $0.15/kWh electricity rate. To reflect charging losses, they add 10% to estimated energy consumed while driving.
12,000 miles/year
20,000 miles/year
15,000 miles/year
Example calculations: electricity cost = (miles ÷ Tesla mi/kWh) × 1.10 × $0.15. Dollar values are rounded. The 10% uplift is an illustration, not a fixed charging-loss rate or necessarily a setting in the existing calculator.

Frequently asked questions
Tesla Savings Calculator FAQs
How accurate is the Tesla Savings Calculator?
It provides an estimate based on the inputs you supply. Your actual costs depend on electricity and gas prices, driving efficiency, weather, charging losses, and the share of charging completed at home versus public chargers.
Is charging a Tesla cheaper than buying gas?
It often can be, especially with lower-cost home electricity, but the result depends on the gasoline vehicle's MPG, electricity prices, public charging costs, and driving patterns. Use the calculator to compare your own numbers.
Does the calculator include charging losses?
The basic miles-per-kWh calculation does not automatically include losses if you enter an efficiency figure measured while driving. For more realistic home-charging estimates, consider additional energy purchased from the grid. The examples on this page use an illustrative 10% uplift.
Does it include maintenance, insurance, and vehicle purchase price?
No. This is an energy-cost comparison, not a complete total-cost-of-ownership estimate. Financing, depreciation, maintenance, insurance, taxes, and charging equipment can change overall ownership costs.
Where can I find reliable electricity and gasoline prices?
Check your utility bill for your electricity rate and local gas stations for gasoline prices. For broader benchmarks, consult the U.S. Energy Information Administration. Vehicle efficiency estimates can be checked through FuelEconomy.gov.
Can I share these savings examples?
Yes. Use the “Copy this example” buttons above. Please include attribution to MyTeslaSavings.com and retain the example assumptions when sharing.

Tesla Savings Calculator: How Much Can You Save on Gas by Driving a Tesla?
Thinking about buying a Tesla but wondering how much you’ll actually save compared with your current gas-powered vehicle?
Our Tesla Savings Calculator makes it easy to estimate how much money you could save each year by charging a Tesla instead of buying gasoline.
Simply enter how many miles you drive each year, your electricity rate, estimated Tesla efficiency, current gas price, and the MPG of the gasoline vehicle you’re comparing.
The calculator will estimate the difference between your annual gasoline costs and Tesla charging costs.
Whether you’re considering a Model 3, Model Y, Model S, Model X, or Cybertruck, changing the numbers to match your driving habits can give you a much more personalized estimate than relying on a generic national average.
How Much Does It Cost to Charge a Tesla at Home?
The cost of charging a Tesla at home depends primarily on two things:
How much electricity your Tesla uses and how much your utility charges per kWh.
For many Tesla owners, home charging is one of the most convenient aspects of owning an EV.
Instead of stopping at a gas station, you can plug the vehicle in when you arrive home and have it ready when you leave again.
If your utility offers cheaper electricity during overnight or off-peak periods, scheduled charging may also help reduce charging costs.
What About Tesla Supercharging?
Our basic calculator is designed primarily to help estimate electricity-versus-gasoline costs using the electricity rate you enter.
If you frequently use Tesla Superchargers, your real-world charging costs may be different from a home-charging estimate.
That’s because Supercharger pricing can vary by location and time.
For someone who charges almost exclusively at home, entering their home electricity rate may provide a useful estimate.
Someone who regularly takes long road trips or relies heavily on Supercharging should account for those higher or varying charging costs when estimating overall savings.
Are Teslas Cheaper to Maintain Than Gas Cars?
Electric vehicles eliminate several maintenance items associated with internal-combustion engines.
A Tesla doesn’t require traditional engine oil changes, spark plugs, engine oil filters, or exhaust-system maintenance.
However, that doesn’t mean maintenance is free.
Tesla owners still need to consider items such as:
- Tires and tire rotations
- Windshield washer fluid
- Wiper blades
- Cabin air filters
- Brake components
- Wheel alignment
- Suspension components
- Other wear items
Tires can be a particularly important expense for EV owners, which is why proper tire pressure, alignment, and regular tire rotations are worth paying attention to.
Ways to Maximize Your Tesla Savings
Buying an EV is only part of the equation.
How you use it can make a major difference.
Whenever practical, consider:
Charge at home.
Home charging can make it easy to take advantage of your residential electricity rate.
Look for off-peak electricity rates.
Some utilities offer EV or time-of-use plans with lower overnight rates.
Schedule charging.
If your utility offers cheaper off-peak electricity, schedule your Tesla to charge during those hours.
Maintain proper tire pressure.
Proper inflation helps your vehicle operate efficiently and promotes better tire wear.
Drive efficiently.
Hard acceleration and sustained high speeds can increase energy consumption.
Use regenerative braking effectively.
Regenerative braking recovers energy during deceleration while reducing reliance on conventional friction brakes.
Compare your actual results.
Once you’ve owned your Tesla for several months, compare your real electricity consumption with what you previously spent on gasoline.
That’s when the savings become much more interesting than an online estimate.
