Switching to an electric vehicle like a Tesla is exciting, but figuring out the costs of charging can feel like navigating uncharted waters. One question often comes up: How much does it actually cost to keep them charged and ready to go?


Understanding the cost of charging a Tesla is crucial, especially compared to the routine of filling up a gas tank. Charging costs can vary widely due to several factors, making it tricky to pin down a one-size-fits-all answer. However, when you break it down, you'll often find that charging is cheaper and more predictable than buying gas, providing a more economical and eco-friendly alternative.


In this article, we'll break down everything you need to know—from home charging to Superchargers and even using solar panels—so you can hit the road with confidence, knowing you're making the most cost-effective and eco-friendly choices.


Key Takeaways 

  • Electricity rates and charging times significantly impact Tesla charging costs.

  • Charging at home is convenient and cost-effective, especially during off-peak hours.

  • Calculating home charging costs involves knowing your Tesla’s battery capacity and local electricity rates.

  • Solar panels can power your Tesla and save money long-term.


What Factors Affect Tesla Charging Costs?

Variations in Electricity Prices 

Electricity prices can be a bit like a rollercoaster...they go up, they go down, and they can vary significantly depending on where you live. This fluctuation plays a huge role in how much you'll pay to charge your Tesla at home.


If you're in a state with higher electricity rates—think California or Hawaii—your charging costs will naturally be higher compared to states with lower rates like Washington or Louisiana.


Charging Time  

The time of day you charge your Tesla can significantly impact your overall costs. Electric rates are often lower during off-peak hours, so if you plug in your car overnight, you’re taking advantage of cheaper rates. 


Suppose your local utility company charges 15 cents per kWh during peak hours (say, 5 PM to 9 PM) and only 10 cents per kWh during off-peak hours (midnight to 6 AM). By scheduling your car to charge overnight, you’re essentially paying a third less for the same amount of electricity. 


Charging Duration 

Another factor is how long it takes to charge. Level 1 chargers are slower but might be adequate if you’re not driving a lot every day. Level 2 chargers, which are faster, will get your Tesla fully charged much quicker.


However, if you’re always topping up instead of letting the battery run low, you might not notice a huge difference in your electric bill. It’s all about finding the right balance for your driving habits and schedule.


Your Location

Where you live plays a critical role in how much you’ll spend to charge your Tesla. States have different electricity rates based on local energy production, infrastructure, and demand. For instance, states with abundant renewable energy sources like hydroelectric power or wind power tend to have lower electricity rates.


But there’s more to it. The climate in your region can also affect how efficiently your Tesla uses its battery. In colder climates, batteries can lose efficiency, requiring more energy to maintain the same range.


Same way extremely hot climates can also drain the battery quicker due to increased use of air conditioning. This means you might find yourself charging more often in extreme weather conditions, slightly increasing your overall costs.


Incentives and Rebates 

Local incentives and rebates can make a big difference. Some states offer incentives for using renewable energy sources, which can reduce your overall electricity costs if you opt for green energy plans. These incentives can help offset the cost of home charging, making your Tesla even more economical to run.


How Much Does Home Charging Cost?

Charging your Tesla at home is probably the most convenient and cost-effective method available. Think of it like plugging in your smartphone at the end of the day. You just connect your car to a home charging station, also known as a Wall Connector, and let it charge overnight.


The cost of charging your Tesla at home largely depends on the electricity rates in your area.  These rates can also fluctuate based on the time of day – many utility companies offer lower rates during off-peak hours, usually late at night or early morning.


It’s crucial to check with your local utility provider to understand your specific rates. Some areas even offer special plans for electric vehicle (EV) owners, providing discounted rates for charging your car at home. 


How to Calculate Home Charging Costs for Different Models

Calculating the cost to charge your Tesla at home is pretty straightforward once you know your electricity rate. First and foremost, you need to know the battery capacity of your Tesla model, which is measured in kilowatt-hours (kWh).


For instance, a Tesla Model 3 Standard Range has a battery capacity of about 57.5 kWh, while a Model S Long Range has around 100 kWh.


Here’s a simple formula to help you out: 


Charging Cost = Battery Capacity (kWh) x Electricity Rate (cents per kWh)


Let’s say you have a Tesla Model 3 and your electricity rate is 12 cents per kWh. Your calculation would look something like this:


57.5 kWh x $0.12 = $6.9


So, it costs roughly $6.9 to fully charge your Tesla Model 3 at home. For a Model S, using the same electricity rate, the cost would be:


100 kWh x $0.12 = $12.00


It’s easy to see how different models and electricity rates can affect your overall charging costs.


How to Calculate Monthly and Yearly Estimates for Home Charging

Now, let's break it down to monthly and yearly estimates. This gives you a better picture of what you might be spending regularly. On average, an American drives about 1,200 miles per month. For a Tesla Model 3, which typically uses around 0.24 kWh per mile, you’d need about 288 kWh to cover that distance.


Using our previous example with a 12 cents per kWh rate:


Monthly Cost = 288 kWh x $0.12 = $34.56


So, if you’re driving a Model 3, you could expect to spend about $34.56 a month on charging. For the whole year, simply multiply by 12:


Yearly Cost = $34.56 x 12 = $414.72


Comparing this to the cost of gasoline for a traditional car, you can see substantial savings. A typical gas-powered car might cost you over $1,200 a year in fuel, depending on gas prices and your vehicle’s fuel efficiency. 


How Much Does Charging At A Tesla Supercharger Cost?

Tesla's branded charging stations called Tesla Superchargers are the ultimate pit stop for your electric vehicle.  With over 50,000 stations in its charging network, you can easily find one using the Tesla app ensuring that you’re never far from a quick and convenient charge, making long trips a breeze.


These high-speed chargers can get you back on the road in no time, perfect for long trips or when you’re in a hurry. Superchargers can add up to 200 miles of range in just 15 minutes – that's like taking a short coffee break while your car gets a massive power boost.


The cost of using a Tesla Supercharger varies but is generally based on the amount of electricity you use, measured in kilowatt-hours (kWh). As of now, Tesla charges about $0.25 per kWh at most Supercharger stations in the U.S., but this can vary by location. For example, some states might have slightly higher rates due to local electricity costs and taxes.


Let’s put this into perspective. If you need to add 50 kWh to your Tesla's battery, the cost would be:


50 kWh x $0.25 = $12.5


This is quite reasonable considering the speed and convenience of Supercharging, especially on long trips.


Tesla occasionally adjusts its rates based on peak demand and local energy prices, so it’s useful to stay updated through the Tesla app or website. Knowing these costs can help you plan your budget for long road trips and manage your charging stops more efficiently.


How Much Do Public Charging Stations Cost?

Public charging stations are becoming more common, providing EV drivers with convenient charging options wherever they go. Companies like ChargePoint, EVgo, and Blink have extensive networks across the country, offering both Level 2 and DC fast charging options.


The cost to use these public stations varies. Some stations offer free charging (often sponsored by local businesses or municipalities), while others charge by the hour or by the kWh. On average, you might pay between $0.20 to $0.30 per kWh at these public stations, similar to Tesla’s Supercharger rates. However, prices can differ significantly based on the provider and location.


Many public charging networks offer membership plans that can reduce your charging costs if you use their stations frequently. But if you’re not a frequent user, pay-as-you-go options are always available.


These allow you to charge your car without any long-term commitment, paying only for the electricity you use. This flexibility is great for occasional use or for trying out different networks before committing to a membership.


Charging costs can vary across different networks, so it’s worth exploring a few options to see which one fits your needs best. Some networks may offer lower rates but have fewer stations, while others might be more expensive but offer more convenient locations and faster charging speeds.
