If you’re considering an electric vehicle, one of the first questions you likely have is how much does charging an electric car cost. Charging an electric vehicle’s battery is often compared to the price of fueling a gasoline car, with costs depending on your local electricity rates.
This guide will break down all the variables. We’ll look at home charging, public stations, and everything in between.
By the end, you’ll be able to estimate your own charging expenses accurately.
How Much Does Charging An Electric Car Cost
The total cost to charge an electric car is not a single number. It varies dramatically based on where you charge, when you charge, and what you drive.
On average, charging at home is significantly cheaper than using public fast chargers. For a typical mid-size EV with a 60 kWh battery, a full charge at home might cost between $6 and $12. The same charge at a public DC fast charger could cost $18 to $30.
To understand your potential costs, you need to consider three core factors: your electricity rate, your car’s efficiency, and your charging location.
Understanding Your Electricity Rate Is Key
Your home electricity bill is measured in kilowatt-hours (kWh). This is the same unit used to measure your EV’s battery capacity and the energy it takes to charge it.
The national average electricity rate in the U.S. is about 16 cents per kWh. However, this varies widely.
- Some states have average rates below 11 cents per kWh.
- Others, like California and parts of the Northeast, can exceed 25 cents per kWh.
You can find your exact rate on your utility bill. Look for the supply charge per kWh. This is the primary cost for charging at home.
Time-Of-Use Rates Can Save You Money
Many utilities offer Time-of-Use (TOU) plans. These plans charge different rates for electricity based on the time of day.
Peak hours (usually late afternoon to evening) are more expensive. Off-peak hours (overnight) are much cheaper.
Since most EV owners charge at home overnight, a TOU plan can lead to substantial savings. For example, an off-peak rate might be 8 cents per kWh, while the peak rate is 30 cents.
Programming your car or charger to start only during off-peak hours is a simple way to cut costs.
Your Electric Car’s Efficiency Matters
Just like miles per gallon (MPG) for gas cars, EVs have an efficiency rating. It’s measured in miles per kilowatt-hour (mi/kWh).
A more efficient EV will travel further on the same amount of electricity, reducing your charging cost per mile.
- A high-efficiency model like the Hyundai Ioniq 6 might achieve 4.0 mi/kWh.
- A larger electric SUV or truck, like the Ford F-150 Lightning, might get closer to 2.0 mi/kWh.
To find your cost per mile, divide your electricity cost per kWh by your car’s efficiency. At the national average of 16 cents/kWh, a car getting 3.5 mi/kWh costs about 4.6 cents per mile. A gas car getting 30 MPG with gas at $3.50 per gallon costs about 11.7 cents per mile.
The Three Levels Of EV Charging Explained
Charging speed and cost are directly linked to the “level” of charger you use. There are three primary levels.
Level 1 Charging: The Slow, Convenient Plug
Level 1 charging uses a standard 120-volt household outlet. Every EV comes with a cord for this.
It’s very slow, adding only about 3 to 5 miles of range per hour. It’s best for plug-in hybrids or EVs with very low daily mileage.
The cost is simply your home electricity rate. There’s usually no extra fees or equipment costs beyond what came with the car.
Level 2 Charging: The Home And Public Workhorse
Level 2 charging requires a 240-volt circuit, similar to an electric dryer or oven. It’s the most common solution for home charging and widely available in public.
- Adds 20 to 40 miles of range per hour.
- A full home installation typically costs $500 to $2,000 for the equipment and electrician.
- Public Level 2 chargers are often found at workplaces, shopping centers, and parking garages.
At home, the cost is still just your electricity rate. At public stations, you might pay a session fee, an hourly rate, or a per-kWh rate, which is often higher than home electricity.
DC Fast Charging (Level 3): For Road Trips
DC Fast Chargers (DCFC) are the high-powered stations along highways. They can charge an EV from 10% to 80% in 20 to 45 minutes.
Pricing here is the most complex and usually the most expensive. Common models include:
- Per-minute pricing (regulated in some states).
- Per-kWh pricing (becoming the standard).
- A combination of a session fee plus one of the above.
Costs at networks like Electrify America or EVgo can be two to four times more expensive than charging at home. They are essential for long trips but not recommended for daily use due to cost and potential battery wear.
Calculating Your Real-World Charging Costs
Let’s put the theory into practice with some clear examples. These calculations assume a 60 kWh battery for simplicity.
Scenario 1: Home Charging On A Standard Plan
Assume your home electricity rate is 16 cents/kWh. A full 60 kWh charge costs 60 x $0.16 = $9.60.
If your car gets 3.5 miles per kWh, that $9.60 gives you 210 miles of range. Your cost per mile is $9.60 / 210 miles = $0.046, or 4.6 cents.
Scenario 2: Home Charging On A Time-Of-Use Plan
You switch to a TOU plan with an off-peak rate of 8 cents/kWh. You always charge overnight.
The same full charge now costs 60 x $0.08 = $4.80. Your cost per mile drops to 2.3 cents. Over 15,000 miles a year, that’s a saving of over $300 compared to the standard plan.
Scenario 3: Public DC Fast Charging On A Road Trip
You stop at a fast charger that costs 40 cents per kWh. You add 50 kWh to your battery.
Your cost is 50 x $0.40 = $20.00. For the 175 miles of range that provides, your cost per mile jumps to about 11.4 cents. This is much closer to the cost of fueling a gas car.
Comparing Costs To Gasoline Vehicles
The financial benefit of an EV becomes clearest when you compare fuel costs directly. Let’s use a consistent example.
Assume 15,000 miles driven per year.
- Electric Vehicle: Efficiency of 3.5 mi/kWh, charging entirely at home at 16 cents/kWh. Annual cost: (15,000 miles / 3.5 mi/kWh) x $0.16 = approximately $685.
- Gasoline Vehicle: Efficiency of 30 MPG, with gas at $3.50 per gallon. Annual cost: (15,000 miles / 30 MPG) x $3.50 = $1,750.
In this scenario, the EV driver saves over $1,000 per year on “fuel.” Even with higher public charging use, the savings are often significant. Maintenance costs for EVs are also generally lower, which adds to the long-term value.
Free Charging Opportunities And Discounts
Not all charging costs money. There are several ways to reduce or eliminate charging expenses.
Employer And Workplace Charging
Many employers offer free Level 2 charging as a perk. This can effectively cover your daily commuting needs, making your home electricity cost for the car very low.
Public Networks With Free Sessions
Some businesses, like certain supermarkets or shopping malls, offer free Level 2 charging to attract customers. While not suitable for a full charge, it can supplement your energy for free while you shop.
Always check apps like PlugShare to locate free stations in your area.
Automaker Charging Programs
Several car manufacturers include complimentary fast charging for a set period. For example, Hyundai, Kia, and Ford have offered plans with Electrify America that include hundreds of kilowatt-hours of free DC fast charging.
These programs are ideal for new owners and can defray the cost of initial road trips.
Hidden Costs And Considerations
While the energy cost is the main factor, a few other financial elements can affect the total picture.
Home Charger Installation
The upfront cost of installing a Level 2 home charger can range from $500 to $2,000. This includes the charging unit itself and an electrician’s labor to run the 240-volt line.
Many states and utilities offer rebates that can cover a portion of this cost. The federal government also previously offered a tax credit for installation; check current laws for available incentives.
Potential For Increased Electricity Tier
In some utility billing structures, high electricity use can push you into a more expensive pricing tier for your entire home’s usage. It’s wise to contact your utility before you get an EV.
They can explain your rate structure and may even suggest a separate meter or a dedicated EV rate plan to avoid this issue.
Public Charging Membership Fees
Some charging networks, like ChargePoint or EVgo, offer monthly membership plans. For a fee (often $4 to $10 per month), you get a reduced per-kWh or per-minute rate.
If you use a specific network frequently, a membership can pay for itself quickly. If you only fast charge occasionally, paying the standard non-member rate is probably fine.
Tips For Minimizing Your EV Charging Bill
Follow these practical steps to keep your costs as low as possible.
- Charge at home overnight. This leverages lower off-peak rates if available and is almost always the cheapest option.
- Install a Level 2 home charger. The convenience and efficiency pay off if you drive regularly.
- Use public fast charging sparingly. Reserve it for long trips, not daily top-ups.
- Plan your charging around discounts. Use free workplace charging or take advantage of automaker programs.
- Monitor your driving efficiency. Smooth acceleration and using regenerative braking can improve your mi/kWh, stretching each charge further.
By adopting these habits, you can maximize the economic advantage of driving an electric car. The savings on fuel and maintence can be substantial over time.
