EV Charging Savings Calculator: Home vs. Public vs. Gas
The average EV owner who charges mostly at public stations is overpaying by $300–$800 per year. Home charging costs 2–4x less per mile than public Level 2 stations — and up to 6x less than DC fast chargers. If you already drive an EV, this calculator shows exactly how much you're leaving on the table.
If you're thinking about switching from a gas car to an EV, this tool shows your real annual savings based on your state's actual electricity rate and AAA's current average gas price — not generic national averages.

Why Home Charging Is Almost Always the Cheapest Option
The economics of EV ownership depend heavily on where you charge. Most EV owners dramatically underestimate how much public charging is costing them — and how quickly a home Level 2 charger pays for itself.
Home electricity in most U.S. states costs between $0.12 and $0.33 per kWh. Public Level 2 charging typically runs $0.35–0.50 per kWh. DC fast chargers at commercial stations often charge $0.43–0.65 per kWh — sometimes more. When you run the math on annual mileage, that gap compounds quickly.
Example: Tesla Model Y in Massachusetts
Driving 250 miles per week (13,000 miles/year) at 3.8 miles/kWh:
All home charging at $0.288/kWh → ~$986/year
80% home / 20% public at $0.48/kWh → ~$1,117/year
Gas car at 28 MPG at $4.20/gallon → ~$1,952/year
Switching to all-home charging saves ~$966/year vs. gas — enough to pay for a quality Level 2 charger in 12–18 months.
How Much Does It Cost to Install a Level 2 Home Charger?
The total cost of a Level 2 home EV charger installation typically runs $1,000–$3,500 all-in for most homes, including equipment and electrical work:
- Charger unit: $400–$800 for a quality 40–48 amp Level 2 charger (ChargePoint Home Flex, Grizzl-E, Tesla Wall Connector)
- Electrician labor + permit: $400–$1,200 depending on your panel and wiring run
- Panel upgrade (if needed): $1,000–$4,000 — only required for older homes without capacity for a dedicated 240V circuit
Most straightforward installs — existing 200-amp panel, charger mounted in the garage near the breaker box — land in the $900–$1,500 range total. The wide upper end reflects long conduit runs, outdoor weatherproofing, or panel upgrade scenarios.
Note on federal tax credits: The Section 30C Alternative Fuel Vehicle Refueling Property Credit, which previously covered 30% of installation costs up to $1,000, expired June 30, 2026 for residential installations. State and utility rebates of $200–$500 are still widely available — check your utility’s website or the DOE’s state incentive database for current programs.
At $800–$1,000/year in savings vs. gas and public charging, most Level 2 charger installations pay for themselves in 12–18 months — then save you money every year after that.
Home vs. Public Charging: When to Use Each
When Public Charging Makes Sense
- Road trips and long-distance travel — DC fast charging is the right tool here
- Emergency top-ups when you forgot to plug in at home
- Apartment or condo dwellers without home charging access
- Workplaces that offer free Level 2 charging — always take it
When Home Charging Is the Right Answer
- Your normal daily commute and around-town driving
- Any session where you'll be parked for 4+ hours
- Overnight charging on a Level 2 — the most cost-effective method available
- Time-of-use rate charging — many utilities offer lower rates during off-peak overnight hours
How to Maximize Your Home Charging Savings
1. Charge During Off-Peak Hours
Many utilities offer time-of-use (TOU) rate plans that charge significantly less for overnight electricity — typically midnight to 6 AM. In California, off-peak rates can be as low as $0.15/kWh vs. $0.45+ during peak hours. Most smart Level 2 chargers let you schedule charging to start automatically at midnight.
2. Pair with Solar Panels
If you have rooftop solar — or are considering it — charging your EV from your own solar production effectively brings your cost per mile to nearly zero. Our Solar + EV Charging guide explains how to set this up.
3. Size Your Charger Correctly
A common mistake is buying more charger than you need. A 32-amp Level 2 charger adds roughly 25 miles of range per hour — enough for most daily drivers to fully charge overnight. Our How Many Amps Does My EV Charger Need? guide covers this in detail.
4. Check for Utility Rebates
Many electric utilities offer rebates of $100–$500 for installing a Level 2 charger. Check your utility's website or the DOE's state incentive database for current programs in your area.
Frequently Asked Questions
Home EV charging costs approximately $0.04–0.10 per mile depending on your state's electricity rate and your vehicle's efficiency. For a typical EV driving 12,000 miles per year, annual home charging costs range from $390 to $1,050 — compared to $1,470–$2,510 for the equivalent gas vehicle fuel cost at today's prices.
Home charging is almost always cheaper — typically 2–4x less per kWh than public Level 2 stations, and up to 6x less than DC fast chargers. Public charging rates average $0.35–0.50 per kWh nationally, while home electricity averages $0.12–0.33 per kWh depending on your state.
The average EV owner saves $1,000–$2,000 per year on fuel by switching from a gas vehicle and charging primarily at home. Savings vary significantly by state — Washington and California drivers save the most due to high gas prices combined with relatively affordable electricity, while lower-gas-price states like Indiana and Louisiana see more modest but still substantial savings.
If you're currently charging 20–30% of your miles at public stations, switching to all-home charging typically saves $500–$900 per year at today's gas and electricity prices. At an all-in installation cost of $900–$1,500 for a typical straightforward install, most chargers pay for themselves in 12–18 months. Note that the federal Section 30C tax credit (30%, up to $1,000) expired June 30, 2026, though state and utility rebates of $200–$500 remain available in many areas.
The cheapest way to charge an EV is at home overnight using a Level 2 charger on a time-of-use electricity rate plan. Off-peak overnight electricity rates in many states are 30–50% cheaper than standard rates. If you have solar panels, charging from your own solar production is even cheaper.
Yes, but typically less than people expect. A typical EV driving 12,000 miles per year adds approximately 3,000–3,500 kWh annually. At the national average rate of $0.184/kWh, that's roughly $550–$645 added to your electric bill — still significantly less than $1,470–$2,510 you'd spend on gasoline for the same mileage at current prices.
States with the lowest home electricity rates as of August 2026 include Idaho ($0.124/kWh), Utah ($0.130/kWh), Oklahoma ($0.134/kWh), Nebraska ($0.136/kWh), and Nevada ($0.136/kWh). Hawaii and California have the highest rates at $0.520 and $0.333/kWh respectively, making the economics more dependent on solar or time-of-use rates.
Home EV Charging Cost by State (2026)
The table below shows exactly what it costs to charge an EV at home in every U.S. state — and how much you save vs. keeping a gas car. All figures use current U.S. EIA residential electricity rates (latest available state-level data) and AAA gas price averages (updated September 6, 2026), calculated for a typical EV driving 12,000 miles per year at 3.8 miles/kWh (Tesla Model Y EPA rating) vs. a 28 MPG gas vehicle. Sorted cheapest to most expensive home charging cost.
