EV Charging Cost Calculator

Find out how much it costs to charge an EV at home, compare it to your gas bill, and see whether you need a Level 2 charger.

One of the biggest questions for new and prospective EV owners is deceptively simple: how much will it actually cost to charge at home? The answer varies wildly depending on where you live, what you drive, and how you charge. Electricity rates range from $0.10/kWh in some states to over $0.30/kWh in others, and battery sizes span from 40 kWh in compact EVs to over 100 kWh in full-size trucks.

This free calculator takes the guesswork out of EV charging costs. Enter your electricity rate (or use the national average), select your vehicle type, and input your typical weekly mileage. The tool estimates your monthly charging cost, shows you exactly how much you would save compared to gasoline, and helps you decide whether a Level 1 charger (standard 120V outlet) or Level 2 charger (240V dedicated circuit) makes sense for your situation.

We built this tool because the "EV charging is cheap" claim needs context. For some drivers, switching from gas to electric cuts fuel costs by 70%. For others in high-rate areas with long commutes, the savings are more modest. Either way, you deserve real numbers based on your situation — not national averages that may not apply to you. No signup required, no data stored. Just honest math.

Frequently Asked Questions

How much does it cost to charge an EV at home? ▼
The average US household pays about $0.16 per kWh, which means fully charging a typical 60 kWh EV battery costs around $9.60. Most drivers spend between $30 and $60 per month on home charging depending on how far they drive. That is roughly 60-70% cheaper than fueling a comparable gas car, though your exact savings depend on local electricity rates and your vehicle's efficiency rating.
Level 1 vs Level 2 charging — which do I need? ▼
Level 1 charging uses a standard 120V household outlet and adds about 3-5 miles of range per hour. It works well if you drive under 40 miles per day and can charge overnight. Level 2 charging requires a 240V outlet (like a dryer plug) and adds 25-30 miles per hour, making it the better choice for longer commutes, larger batteries, or households with multiple EVs. The calculator above factors in your driving habits to recommend the right level.
Does time-of-use pricing affect my EV charging costs? ▼
Significantly. Many utilities offer time-of-use (TOU) rate plans where electricity costs less during off-peak hours, typically between 9 PM and 6 AM. Charging during off-peak hours can cut your costs by 30-50% compared to peak rates. Most modern EVs and Level 2 chargers let you schedule charging to start automatically during the cheapest hours. Check with your utility to see if a TOU plan or dedicated EV rate is available in your area.
How does home charging compare to public charging stations? ▼
Home charging is almost always cheaper. Public Level 2 chargers typically cost $0.20-$0.35 per kWh, and DC fast chargers can run $0.30-$0.60 per kWh or more. At home, you pay your standard residential electricity rate, which averages $0.16 per kWh nationally. The main advantage of public charging is speed — DC fast chargers can add 200 miles in 20-30 minutes — but for daily driving, overnight home charging is the most economical option by far.
