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 Does the Tesla Savings Calculator Work?

The biggest day-to-day financial difference between driving a Tesla and a gasoline vehicle is how you “fuel” the vehicle.

A gasoline vehicle requires gallons of gasoline.

A Tesla requires electricity measured in kilowatt-hours (kWh).

Our calculator estimates the annual cost of each based on the information you provide and then compares the two.

Miles Driven Per Year

Start by entering approximately how many miles you drive annually.

If you’re not sure, you can estimate your annual mileage using your daily commute.

For example, someone driving approximately 40 miles per weekday just commuting to work could accumulate more than 10,000 miles annually before accounting for weekends, vacations, shopping, and other trips.

The more you drive, the larger the potential difference between gasoline and electricity costs can become.

Cost of Electricity Per kWh

Enter the price you pay for electricity at home in dollars per kilowatt-hour (kWh).

You can usually find this information on your electric utility bill.

For the most accurate estimate, try to determine the actual rate you pay when your Tesla would normally be charging.

Some electric utilities offer time-of-use plans where electricity is significantly cheaper during off-peak hours.

If you primarily charge overnight at a discounted rate, use that rate in the calculator.

Tesla Efficiency — Miles per kWh

A Tesla’s efficiency tells you approximately how far the vehicle can travel using one kilowatt-hour of electricity.

Efficiency varies depending on several factors, including:

If you already own a Tesla, using your actual energy consumption can provide an even more personalized estimate.

If you’re shopping for a Tesla, you can experiment with different efficiency assumptions to see how the result changes.

Gas Price Per Gallon

Enter the average price you currently pay for gasoline.

Gas prices can fluctuate substantially over time and by location, so don’t worry about finding a perfect number.

Use approximately what you’re currently paying at the pump.

You can also experiment.

Try calculating your savings at:

$3.00 per gallon

then:

$4.00 per gallon

and even:

$5.00 per gallon

This helps demonstrate how your potential Tesla savings change if gasoline prices increase or decrease.

Your Current Gas Car’s MPG

Next, enter the fuel economy of the gasoline vehicle you’re comparing with the Tesla.

For example, if your current vehicle averages 25 MPG, enter:

25 MPG

A driver replacing a large SUV or pickup that gets relatively low fuel economy could potentially see a much larger difference in energy costs than someone replacing a highly efficient hybrid.

That’s why comparing a Tesla with your actual vehicle is much more useful than simply comparing it with an “average car.”

Tesla Charging Cost vs. Gas Cost

The basic comparison is surprisingly simple.

For a gasoline vehicle:

Annual Gas Cost = Annual Miles ÷ MPG × Gas Price

For a Tesla:

Annual Charging Cost = Annual Miles ÷ Miles per kWh × Electricity Price

The difference between those two estimates represents your potential annual energy savings.

Simple Example

Suppose you drive:

12,000 miles per year

Your current vehicle gets:

25 MPG

And gasoline costs:

$3.50 per gallon

Your estimated annual gasoline usage would be:

12,000 ÷ 25 = 480 gallons

At $3.50 per gallon:

480 × $3.50 = $1,680 per year

Now imagine your Tesla averages:

4 miles per kWh

and you pay:

$0.15 per kWh

Your estimated electricity usage would be:

12,000 ÷ 4 = 3,000 kWh

At $0.15 per kWh:

3,000 × $0.15 = $450 per year

That produces an estimated difference of:

$1,230 per year

Over five years, if those prices and driving habits remained the same, that’s approximately:

$6,150 in energy savings.

Of course, your actual results will depend on your Tesla, driving habits, charging method, electricity rates, gasoline prices, weather, and other factors.

That’s exactly why we created the calculator.

Instead of relying on somebody else’s assumptions, enter your own numbers.

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.

How Much Could a Tesla Save Over 5 Years?

One of the most interesting ways to use our calculator is to multiply your estimated annual savings over several years.

For example:

$500/year = $2,500 over 5 years

$1,000/year = $5,000 over 5 years

$1,500/year = $7,500 over 5 years

$2,000/year = $10,000 over 5 years

These aren’t promises of future savings because gasoline prices, electricity rates, mileage, efficiency, and charging habits can all change.

But they demonstrate why seemingly small differences in cost per mile can become significant when multiplied across tens of thousands of miles.

Does the Tesla Savings Calculator Include Maintenance?

No.

This calculator is primarily intended to compare the cost of gasoline versus electricity.

It doesn’t attempt to calculate every possible cost associated with vehicle ownership.

Other expenses can include:

Keeping these expenses separate makes it easier to understand exactly what the calculator is showing you.

Think of the result as an estimated fuel/energy savings comparison, rather than a complete Tesla total-cost-of-ownership calculation.

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 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.

Tesla Savings Calculator FAQ

How much money can you save on gas with a Tesla?

There isn’t one number that applies to every driver. Your savings depend on annual mileage, gasoline prices, the MPG of the vehicle you’re replacing, Tesla efficiency, electricity prices, and where you charge. Use the calculator above with your own numbers for a personalized estimate.

Is charging a Tesla cheaper than buying gas?

It can be, particularly when charging at home at favorable electricity rates, but the answer depends on your electricity rate and the gasoline vehicle you’re comparing against. Enter your local electricity and gasoline prices into the calculator to compare them directly.

How much does it cost to drive a Tesla per mile?

Divide your electricity price per kWh by the number of miles your Tesla travels per kWh.

For example, at $0.16/kWh and 4 miles/kWh:

$0.16 ÷ 4 = $0.04 per mile

That’s approximately four cents of electricity per mile in this simplified example.

How do I find my electricity rate?

Check your latest electric utility bill. For the most useful comparison, determine your effective cost per kWh or the rate that applies during the hours when you normally charge your Tesla.

Does cold weather affect Tesla efficiency?

Yes. Temperature, cabin heating, battery conditioning, road conditions, speed, and other factors can affect energy consumption. Drivers in cold climates may notice higher electricity consumption during winter.

Does this calculator include Supercharger costs?

The calculator uses the electricity price you enter. If you primarily charge at home, enter your home electricity rate. If a substantial percentage of your charging occurs at Superchargers, remember that your actual average charging cost may be higher or otherwise different.

Does the calculator include Tesla maintenance savings?

No. It focuses on comparing gasoline and electricity costs. Maintenance, insurance, depreciation, financing, tires, taxes, incentives, and purchase price should be evaluated separately when comparing total vehicle ownership costs.

Calculate Your Tesla Savings

The best way to determine whether switching from gasoline to a Tesla could save you money is to stop relying on generic averages.

Enter your own:

Annual mileage + electricity rate + Tesla efficiency + gas price + current vehicle MPG

into the Tesla Savings Calculator above.

Then try changing the numbers.

Compare today’s gas price with $4 or $5 per gallon. Compare your current electricity rate with an off-peak EV charging rate. Try different annual mileage figures.

You’ll quickly see which factors have the biggest impact on your potential savings.

And if you’re already a Tesla owner, come back periodically and plug in your actual electricity costs and driving efficiency.

You might be surprised by how much you’ve saved by driving electric.
