Electric vehicles (EVs) are taking the world by storm... and for good reason. They’re cleaner, quieter, and often cheaper to operate than their gasoline-guzzling counterparts. But when you’re new to the EV scene, one burning question likely comes to mind: How much does it cost to charge an EV? 

Key Takeaways 

  • Local electricity rates greatly influence EV charging costs.

  • Home charging is generally more cost-effective than public stations.

  • Solar panels can significantly reduce or eliminate EV charging costs.

  • Different EV models have varying charging costs based on efficiency.

What Factors Affect the Cost of Charging an EV?

Several factors come into play when determining the cost of charging your EV. It’s not just about plugging in and paying a flat rate; various elements influence what you'll end up paying.

Electricity Rates and Their Variability

Your local electricity rates play a huge role in the cost of charging your EV. Electricity prices can vary greatly depending on your location. For example, residents in states with lower electricity rates, like Washington, pay significantly less per kilowatt-hour (kWh) compared to those in states like California, where electricity can be more expensive.

Many utility companies also offer time-of-use rates, meaning electricity is cheaper during off-peak hours, usually late at night. Charging your EV during these times can help you save money.

Vehicle Efficiency and Battery Size

Just like gas mileage varies between traditional cars, electric vehicles also differ in efficiency. Some EVs can travel more miles per kWh than others. For instance, a highly efficient EV like the Tesla Model 3 might consume less electricity per mile compared to a larger, less efficient model.

The size of the battery also affects charging costs. Larger batteries, while providing a greater range, require more electricity to charge fully. So, a vehicle with a 100 kWh battery will cost more to charge than one with a 60 kWh battery, though it will also typically travel further on a full charge.

Charging Speed and Types of Chargers

When it comes to charging, not all chargers are created equal. The type of charger you use can impact your costs. There are three main types of chargers:  

  • Level 1 Chargers: These use a standard 120-volt outlet and are the slowest charging option. They’re great for overnight charging at home but can take a long time to fully charge an EV.   They're often included with the purchase of an EV.

  • Level 2 Chargers: They require a 240-volt outlet and are much faster, making them a popular choice for home installations and public charging stations. Installation costs can range from a few hundred to a couple of thousand dollars, but many areas offer incentives to offset these costs.

  • DC Fast Chargers: These are the fastest but also the most expensive option, usually found at public charging stations. They can charge an EV to 80% in about 30 minutes. They are  ideal for long road trips or quick top-ups.

Charging Location 

Where you charge your EV also affects the cost. Charging at home is generally the most cost-effective method, especially if you can take advantage of off-peak electricity rates. Installing a home charger involves an initial setup cost, but it pays off in the long run with lower per-charge costs. Public charging stations, on the other hand, can be more expensive.

The pricing structures vary widely—some charge per kWh, others by the minute, and some even offer subscription models. Public chargers, especially DC fast chargers, tend to have higher rates due to the convenience and speed they offer.

Home Charging

Charging at home tends to be the most convenient and cost-effective option. If your electricity rate is $0.13 per kWh and your EV has a 60 kWh battery, a full charge would cost around $7.80. This gives you a substantial saving compared to fueling a gasoline vehicle, which could easily cost three or four times that amount for the same range.

The exact cost can fluctuate based on local electricity rates and your car’s efficiency, but home charging consistently offers a low-cost solution.

Public Charging

Public charging stations vary in cost and pricing structure. Many charge by the minute or by the kWh. For instance, a public Level 2 charger might cost around $0.20 per kWh, while a DC fast charger could cost about $0.40 per kWh.

For a 60 kWh battery, this translates to $12 and $24, respectively, for a full charge. Some networks offer subscription models where you pay a flat monthly fee for unlimited charging—great for frequent travelers but potentially overkill for occasional users.

How to Calculate the Cost to Charge an EV

Calculating the cost to charge your electric vehicle (EV) is easier than you might think. By following a few simple steps, you can get a clear picture of what you'll be paying.

1. Determine Your Vehicle’s Battery Capacity

First, you need to know the battery capacity of your EV, measured in kilowatt-hours (kWh). This information is typically available in your vehicle's manual or on the manufacturer's website. For example, the Nissan Leaf has a 40 kWh battery, while the Tesla Model S can have up to a 100 kWh battery.

2. Find Your Local Electricity Rate

Next, check your local electricity rate, which is how much you pay per kWh. This information can be found on your utility bill or your utility company's website. Rates can vary significantly by location and time of day, with off-peak hours often being cheaper.

3. Calculate the Cost of a Full Charge

To find out how much it costs to fully charge your EV, multiply the battery capacity by your local electricity rate. For instance, if your EV has a 60 kWh battery and your electricity rate is $0.12 per kWh, the cost for a full charge would be:

Cost = Battery Capacity (kWh) x  Electricity Rate

Cost = 60 kWh x  $0.12 kWh = $7.20 

4. Estimate Your Monthly Charging Cost

To estimate your monthly charging cost, you need to know your average monthly driving distance and the efficiency of your EV (miles per kWh). For example, if you drive 1,000 miles per month and your EV gets 4 miles per kWh, you'll need:

Energy Needed = Monthly Miles Driven/Miles per kWh

Energy Needed = 1,000 /4miles per kWh = 250 kWh

Then, multiply the energy needed by your electricity rate:

Monthly Cost = 250kWh x  $0.12kWh = $30

5. Factor in Charging Location and Type

Remember that these calculations are based on home charging rates. If you frequently use public charging stations, costs can vary. Public Level 2 chargers might charge around $0.20 per kWh, while DC fast chargers can cost $0.40 or more per kWh. Adjust your calculations accordingly if you use these services regularly.

Let's put this into a practical example. Suppose you have a Chevy Bolt with a 66 kWh battery and you live in Texas, where the average electricity rate is $0.14 per kWh. Here’s how you’d calculate:

Full charge cost: 66kWh x $0.14kWh = $9.24

If you drive 1,200 miles a month and the Bolt gets 4 miles per kWh, you’ll need 300 kWh:

300kWh x $0.14kWh = $42

How Can You Optimize EV Charging to Save Money?

Charging your EV efficiently can help you save a lot of money over time. Here are some practical tips to get the most out of your EV charging:
