When thinking about a future electric vehicle purchase like a Tesla, your first thought might be, “how much does a Tesla cost?” Well, we’ve already covered that for you. If you’re like many people and are new to the world of electric vehicles, your next question might be, “how much does it cost to charge a Tesla?”

Excellent question, it costs $10. Just kidding, it’s unfortunately not that cut and dry. Below is a detailed breakdown of the factors that contribute to the cost of EV charging and easy ways to estimate how much you may pay to charge your next electric vehicle, regardless of make or model.

## Introduction to EV charging

Before we dig right into the monetary differences in how much it costs to charge a Tesla, it’s important to understand the differences between charging levels. While each level offers different rates of charges based on a number of factors, these choices will also affect how little or much you pay while you charge back up.

### Level 1 AC charging

Think of Level 1 as the universal charging option. If there is a standard wall socket nearby, you will be able to charge your Tesla without issue… or speed. Realistically, 110-120V is the bare minimum amount of juice you can pull into your EV. So if the battery capacity of your 2021 Tesla Long Range Model 3 is 82 kWh, you’re looking at days to charge, not hours.

### Level 2 AC charging

These chargers are the most common type found at third-party public stations. 220-240V plugs usually offer around 40 to 50 amps and are usually more strategically placed when in a home. This level of power is equivalent to your dryer or another large appliance.

Tesla encourages owners to install a Level 2 charger in their home if they can, which is usually a fairly easy process for an electrician or specialist to install. With Level 2, you can charge your Tesla in around 8-12 hours.

### Tesla Supercharger (DC Fast Charger)

Level 3 chargers or DCFCs, abandon the alternating current (AC) methods above to mainline power directly from the grid. While they require a lot more power (480+ volts and 100+ amps), their output is tenfold greater.

Most Tesla Superchargers can now recharge up to 200 miles of range in only 15 minutes, depending on the charge rate. Superchargers also range from charging speeds of 90 kW to 250 kW, depending on what Supercharger you end up at.

Due to their massive direct current (DC), Superchargers are not recommended for daily Tesla charging. Instead, Superchargers provide a quick charge for drivers on the go or for those making pit stops on longer road trips.

Recently, Elon Musk has stated Tesla’s plans to implement 300 kW Superchargers, but we have yet to see them. Most recently, Tesla shared that it plans to triple the size of its Supercharger network within the next two years. Great news for EV adoption, especially when the automaker begins allowing other EV models to use its chargers.

Looking for more info on Tesla’s Supercharger network? Perfect, we’ve already put together a comprehensive guide for you. Here’s a throwback to the first Tesla Supercharger pile in Hawthorne, CA.

### Other important factors to note

The prices below cover the approximate cost of charging your Tesla EV from 0 to 100 percent, even though you should never let your vehicle battery get to 0 percent. Furthermore, you generally shouldn’t charge your Tesla all the way to 100 percent unless you need that full range for a long trip, and plan to drive it shortly after charging.

Also, remember that AC chargers are not perfectly efficient, and more kWh of energy is required to replenish a battery pack than the actual battery capacity itself.

This is because the vehicle has to convert the alternating current (AC) from the electrical circuit to a direct current (DC) that can be successfully used to charge the battery.

As a result, the efficiency of the charger decreases, especially as your EV battery creeps closer to full capacity, since the level of heat increases, releasing precious energy.

Luckily, Teslas can use this heat for things like battery preconditioning in cold weather, but for the sake of strictly charging, you will require more kWh of energy to charge your battery than the actual battery size.

## How much does it cost to charge a Tesla at home?

To begin, we will compare prices of each Tesla model based on the AC charging capabilities available to you at your abode. By using some relatively novel math, we can determine approximately what it may cost you to charge your Tessie on average in the US.

Then, you can use this math later to determine a more precise cost in your home state… if you want. The data used to approximate these costs was gathered from the US Energy Information Administration (EIA), which was last updated in August of 2021.

For the costs associated with charging from home, we used the US average costs for residential energy usage in cents per kiloWatt hour (kWh). This averages out to $0.1399 per kWh, but we will round up to $0.14 to keep things neat.

Additionally, we are using the current Tesla models listed on its website to figure the latest battery sizes and estimated range.

### Tesla Model S

Both the Long Range and Plaid Model S feature a 100 kWh battery pack, a nice clean number to do our math with. So for 100 kWh of energy, you’re looking at $14, but not so fast! Remember our paragraph above, AC chargers are not perfectly efficient, so we must account for that in our equation.

Average efficiency rates for Level 1 and Level 2 AC chargers fall between 80-90%, so we will call it right down the middle at 85% efficiency. So where were we?

With a 100 kWh battery on the Model S at $0.14 per kWh, plus the 15% additional energy required due to inefficiency, it will cost approximately $16.47 to fully charge your Model S from 0-100%. Realistically, it should be less than that depending on your starting battery life.

Now, the Model S Long Range currently has an EPA estimated range of 405 miles, which means you’d be paying about $0.041 per mile or $4.07 for 100 miles of range.

The Model S Plaid has an estimated range of 396 miles, coming out to $0.042 per mile or $4.22 per 100 miles.

### Tesla Model X

Like its older sedan sibling, both upcoming trims on the Model X feature a 100 kWh battery pack as well. Same battery size, same price – $16.47 to fully charge your Model X from 0-100%.

However, the Model X is a larger and heavier Tesla than the Model S and comes with a lower range, so let’s calculate cost per mile. First, the Model X Long Range, at an estimated range of 360 miles, will cost about $0.046 per mile and $4.58 for 100 miles of range.

For the speedier but lower range Model X Plaid, its 340-mile estimated range costs roughly $0.048 per mile and $4.84 per 100 miles.

### Tesla Model 3

Let’s dig into the newer models next, beginning the cheapest Tesla to date, the Model 3. This Tesla gets a little more interesting because its trims vary in battery size. For instance, the Standard Range Plus Model 3 comes with a 50 kWh battery, while the Long Range and Performance versions sit upon a 82 kWh battery.

Let’s start with the smallest and go bigger. A 50 kWh battery on the Tesla Model 3 Standard Range Plus will cost approximately $8.24 to fully charge. Not too shabby.

With added battery comes range, but with added range comes additional charging. Longer charging means additional cost, so let’s calculate the Long Range and Performance trims. An 82 kWh battery will cost, on average in the US, $13.51 to go from 0-100%, accounting for an 85% charging efficiency.

Now, let’s talk mileage. The Long Range Model 3 offers an EPA estimated 353-mile range, which equates out to about $0.038 per mile and $3.83 every 100 miles. Performance trim on the Model 3 is not far behind at an EPA range of 315 miles, costing around $0.043 per mile or $4.39 per 100 miles.

Last but not least (unless we’re talking range) is the Standard Range Plus Model 3. Its 262-mile range will run you approximately $0.032 per mile and a very reasonable $3.15 for 100 miles of range.

### Tesla Model Y

Until Cybertruck someday delivers, the newest Tesla to hit roads in the US remains the Model Y. Currently available in two trims, both the Long Range and Performance versions feature a 75 kWh battery.

That means it will cost a Model Y owner in the US approximately $12.35 on average to fully charge their Tesla.

To break it down in terms of mileage, the Model Y Long Range and its EPA estimated 326-mile range will cost roughly $0.038 per mile or $3.79 per 100 miles of range.

Additionally, the 303 miles of EPA range on the Performance version of the Tesla Model Y comes out to about $0.041 per mile or, better yet, $4.08 per 100 miles.

## Cost to charge a Tesla Supercharger/DCFC

DC Fast Chargers get you back on the road fully juiced a lot quicker, but it may cost you more for the advantage of speed.

Again, these prices very much depend on where you’re charging, the rates during the time of charge, and how much energy you’re actually taking from the grid.

On average, commercial energy prices are cheaper in the US. However, Tesla’s Supercharger network doesn’t necessarily utilize commercial rates, and certainly doesn’t charge customers that low of a rate.

Like the residential numbers, we will again utilize data from the EIA for average energy costs in the US. However, to account for this upcharge present on DC Fast Chargers, we will add an additional $0.10 per kWh. As a result, we get $0.216 per kWh, so we feel safe rounding up to a cool 22 cents.

DCFC’s like Tesla Superchargers snag DC power directly without having to convert it for your EVs battery, making them much more efficient compared to Level 1 and 2 charging. Charging efficiencies range from around 90% to 99%, so for our estimates, we will call it 95%.

### Tesla Model Y

This time we will start with the youngest and go from there. You know the drill by now; the Model Y features a 75 kWh battery. Multiply that by the average commercial cost of $0.22 per kWh, account for 95% efficiency, and you’re looking at a price of $17.21 to charge the Tesla on a Supercharger or DCFC equivalent.

Breaking it down in terms of mileage, the Long Range Model Y costs approximately $0.053 per mile or $5.28 per 100 miles.

On the other hand, a Performance Model Y will run you about $0.057 per mile and $5.68 for 100 miles of range.

### Tesla Model 3

Moving on to the least expensive Tesla, the 50 kWh battery on the Standard Range Plus Model 3 will cost approximately $11.47 to fully charge, while the 82 kWh batteries on the other trims will run you about $18.82 each.

A Standard Range Plus Model 3 comes out to roughly $0.044 per mile and $4.38 for 100 miles of range. Meanwhile, the Performance Model 3 and its 315-mile range will cost about $0.060 per mile and around $5.97 for 100 miles.

Lastly, the 353 miles on the Long Range 3 equals out to approximately $0.053 per mile and about $5.33 per 100 miles.

### Tesla Model X

Our last two Tesla models should go quickly as they both utilize a 100 kWh battery pack. That means in order to charge from 0-100%, accounting for 95% battery efficiency, it will cost approximately $22.95 to fully charge a Model X via DC Fast Charging.

Cost per mile is where things vary, however. The Long Range Model X comes is around $0.064 per mile and $6.37 per 100 miles, while the 340 available miles on the Plaid will cost roughly $0.068 per mile or $6.75 for 100 miles of range.

### Tesla Model S

Both versions of the Model S also feature the 100 kWh battery (see above). That being said, let’s skip right through to the cost per mile.

The Long Range Model S comes out to $0.057 per mile and approximately $5.67 for 100 miles of range. With a lower estimated range, the Model S Plaid will cost you about $0.059 per mile and $5.88 per 100 miles.

## Ways to save money charging your Tesla EV

The numbers above are simply estimates to give you an idea of the sorts of cost differentials between charging levels. Again, additional factors such as your location, charger, and whether its peak energy hours can all play a big role.

Either way, they should offer some idea of how to most effectively choose what style of charging is best for your given battery level situation. Additionally, there are other ways to save yourself some cash on public charging networks.

### Does Tesla still offer free Supercharging?

Yes, but not recently. When Tesla EVs really began ramping up deliveries to customers after the debut of the Model S, many customers saw added perks like unlimited Supercharging. Over time, Tesla has incorporated similar promotions for specific models or customers who made a referral.

However, this still remains one of the most confusing potential perks for Tesla owners, old and new. We get a lot of questions, such as: *How can I tell if my Tesla has free unlimited Supercharging?; Does free Supercharging transfer over?*; and* Does Tesla still offer free Supercharging? *

We will have to get more granular on this in a separate post, but here are some broad strokes:

- Since mid-2020, Tesla has made no mention of additional free unlimited Supercharging
- Fully-transferable, free unlimited Supercharging has not been offered since 2017
- As the newest Tesla, the Model Y has never seen any free Supercharging promotions
- The best way to check if you or your Tesla have free unlimited Supercharging is to contact Tesla directly

Here’s a breakdown of what Tesla models *may* still have a promotion for free unlimited supercharging. We’ve also put together a more detailed guide here.

Remember to check with Tesla to confirm if your EV qualifies or not:

**Note: No Tesla models from 2021 onward have any promotions for unlimited Supercharging at this time*

Tesla Model | Year(s) | Unlimited Supercharging status |

Model Y | 2020-2021 | None |

Model 3 | 2018-2019 | Performance trim only and must be original owner |

Model X | 2016-2020 | Potentially available, confirm with Tesla |

Model S | 2012-2020 | Potentially available (excluding the S 40), confirm with Tesla |

### Third party charging networks offer occasional discounts

No matter what EV you drive, there are public charging options at your disposal from other networks aside from Tesla. Each has its own app, automotive partners, and deals for those who decide to charge with them.

These deals are always evolving, and can apply to certain customers for purchasing a particular vehicle or can last a day or two for all customers during special events like holidays.

Do your research to see what charging networks have a footprint in your area and see what sort of promotions they may be offering.

Here are some places to start:

- Alternative Fuels Data Center (AFDC)
- AmpUp
- ChargeHub
- Chargemap
- ChargePoint
- Chargeway
- EVgo
- Greenlots
- Open Charge Map
- PlugShare
- VoltaCharging

## How to estimate the cost to charge any EV

So what if you don’t have a Tesla? Are you somehow unworthy of knowing your cost to charge too? That couldn’t be further from the truth, my friends. No matter what zero-emission make or model you drive, you can still determine how much it will cost you to charge your electric vehicle.

Here’s a semi-simple way to figure it out

**Find your EV’s battery size (kWh).****Note the EPA estimated range of your EV, or the average range your specific EV is currently getting you.****Visit the EIA website**Look up the average cost of residential electricity in your state, or in the US as a whole.

Remember, these numbers are cents per kWh, so you’ll want to move that decimal place over to get to dollars.

(ex: 22.10 = $0.22)**Multiply your cost per kWh x the size of your battery.**(ex: 0.22 x 75 kWh = $16.50 to fully charge)

**REMEMBER: We also need to account for charging efficiency (~85% for home and ~95% DCFC).**Ex: $16.50 / 85 = 0.0194 x 15 = $2.91 (additional cost from energy lost during charging)

**Lastly, add for your total:**$16.50 + $2.91 = $19.41 to fully charge your 75 kWh battery from 0-100%

Now that we have that, we can calculate costs in terms of miles:

**Take your total cost to charge, and divide it by your EV’s range, for an example we will say 305 miles:**

$19.41 / 305 = $0.064 per mile (rounded)

**Now multiply that by 100 to get your cost per 100 miles:**

0.064 x 100 = $6.36 for 100 miles of range
