The Cost of Charging an EV at Home
For most EV owners, charging at home is the most convenient and cost-effective option. However, your electricity rate will determine how much your EV charger adds to your bill.
Factors That Affect the Cost of Charging at Home
Electricity Rate & Peak Hours
- Utility companies charge different rates based on the time of day. Charging during peak hours (typically late afternoon and evening) costs more than off-peak hours (late at night or early morning).
- Some providers offer time-of-use plans that provide lower rates during off-peak hours, which can help reduce your charging costs.
Battery Capacity & Level 2 Charger
- The battery capacity of your EV determines how much electricity is needed to fully charge it.
- A Level 2 charger charges faster and is more efficient than a Level 1 charger, but it may require an initial installation cost.
Charging Frequency
- The more you charge your EV, the higher your bill will be. EV owners who drive long distances daily will see a greater impact on their electric bills compared to those who drive occasionally.
Home Charging Cost Breakdown
Let’s say your electricity rate is $0.12 per kWh, and your EV has a 60 kWh battery:
- Cost to fully charge = 60 kWh × $0.12 = $7.20 per full charge
- If you charge four times per month, the total cost will be $28.80 per month
- If your electricity rate is higher or you charge more frequently, your costs will increase.

Charging at Public Charging Stations
While charging at home is the most affordable option, many EV owners need to use public charging stations at some point, especially on long trips. However, the cost to charge at public stations is often higher than the national average electricity rate.
Varieties of Public EV Charging Stations
Level 2 Chargers (Common in public places)
- Charging speed: 10-30 miles per hour of charging
- Cost: Varies but typically $0.20 – $0.30 per kWh
- Best for: Shopping centers, workplaces, and restaurants
DC Fast Chargers (Found along highways)
- Charging speed: 80% charge in 30 minutes
- Cost: Higher than Level 2 chargers, usually $0.30 – $0.50 per kWh
- Best for: Road trips and quick top-ups
Cost Comparison: Home vs. Public Charging
| Charging Method | Average Cost per kWh | Full Charge Cost (60 kWh Battery) |
|---|---|---|
| Charging at Home | $0.12 | $7.20 |
| Level 2 Public Charger | $0.25 | $15.00 |
| DC Fast Charger | $0.40 | $24.00 |
How to Lower Your EV Charging Costs
If you’re worried about how much charging an EV raises your electric bill, there are ways to reduce your costs:
1. Charge During Off-Peak Hours
- Many utility companies offer time-of-use plans with lower rates at night.
- Charging your vehicle overnight can save $10 – $20 per month compared to charging during peak hours.
2. Install a Level 2 Charger at Home
- While a Level 2 charger requires an upfront installation cost, it charges faster and more efficiently than a standard wall outlet, saving you money in the long run.
3. Use Public Charging Wisely
- Avoid DC fast chargers unless necessary, as they are the most expensive option.
- If you must use public charging stations, look for networks that offer membership discounts.
4. Monitor Your Charging Habits
- Charging only when needed and keeping your battery between 20-80% can extend battery life and reduce electricity waste.
Final Thoughts: How Much Does Charging an EV Raise Your Electric Bill?
So, how much does charging an EV raise your electric bill? On average, charging EVs at home adds $30 to $60 per month to your electricity bill. This cost depends on your electricity rate, battery capacity, charging frequency, and peak charges.
For EV owners who use public charging stations, costs can be higher than the national average, especially if using DC fast chargers. The best way to save money is to charge at home during off-peak hours and install a Level 2 charger if possible.
By managing your charging habits, you can enjoy the benefits of electric vehicles (EVs) while keeping your costs low.
