How this calculator works
All calculations run in your browser. No data is sent anywhere.
Effective mi/kWh = EPA mi/kWh × real-world adjustment × battery health Annual home kWh = (annual miles × home share) ÷ effective mi/kWh Home cost = net home kWh × electricity rate Public cost = (annual miles × public share) ÷ (EPA mi/kWh × adjustment) × public rate Annual total = home cost + public cost Monthly = annual total ÷ 12 Cost per mile = annual total ÷ annual miles Gas cost = (annual miles ÷ gas MPG) × gas price
- Vehicle efficiency values are EPA wall-to-wheel figures.
- State rates are typical residential averages from EIA.
- Real-world adjustment defaults to 100% (EPA baseline).
- Charger installed cost uses DOE AFDC and RSMeans midpoint ($1,100).
- Solar offset assumes self-consumption; no export credit modeling.
- Battery health applies a linear efficiency adjustment.

Frequently asked questions
How much does it cost to charge an EV at home?
At the US average residential rate of ~18.83¢/kWh, a typical EV driving 10,787 miles/year at ~3.5 mi/kWh costs roughly $45–$80 per month, depending on the vehicle.
Is charging at home cheaper than gasoline?
In most US states, yes. Home charging costs about 5–6¢ per mile; a 30 MPG car at $3.10/gal costs about 10.3¢ per mile. High-electricity states (Hawaii, California) narrow the gap unless you charge off-peak.
How much does a Level 2 charger cost to install?
Hardware $380–$690, installation $400–$800, totaling roughly $800–$1,500 before incentives. A 30% federal tax credit reduces net cost by about 30% if applicable.
Does charging increase my electric bill?
Yes — by roughly the amount this calculator estimates (typically $40–$80/month for average US driving). Many utilities offer time-of-use plans that reduce the increase by 30–60% if you charge overnight.
What is the cheapest time to charge?
Overnight, typically 9 PM–6 AM. Off-peak rates on many TOU plans are 40–70% lower than peak. Use the TOU fields to compare.
How does battery health affect charging cost?
A degraded battery delivers fewer miles per kWh. A used EV at 85% state of health may need roughly 15–18% more energy for the same miles.
Why is public charging more expensive?
DC fast charging carries equipment, demand-charge, and network costs that residential rates don't. Public charging typically runs $0.35–$0.60/kWh vs $0.10–$0.35/kWh at home.
Can solar eliminate charging cost?
Partially or fully depending on system size and driving. A typical 8,000–10,000 kWh/year array can cover most of an average EV's annual charging needs.
Wall vs battery energy?
Wall energy is what the charger draws from the grid; battery energy is what reaches the battery. Charging losses of 5–15% mean wall energy is always higher. EPA efficiency ratings are typically wall-to-wheel and already include those losses.
How accurate is this calculator?
It provides an estimate based on your inputs and published government data. Actual costs vary with real-world efficiency, seasonal rates, driving conditions, and your utility's rate structure. Use it for planning, not as a utility bill prediction.
Estimates only. Verify rates, incentives, and vehicle specifications with your utility, tax advisor, and manufacturer before making financial decisions.
EV Home Charging Cost Calculator: What You'll Actually Pay
Charging an electric vehicle at home costs the average US driver roughly $45 to $80 per month, or about 5 to 7 cents per mile, based on the US residential average electricity rate of 18.83¢/kWh (EIA, April 2026) and average light-duty vehicle mileage of 10,787 miles per year (FHWA, 2024). Your actual cost depends on four main variables: your electricity rate, your vehicle's efficiency, how many miles you drive, and how much of your charging happens at home versus on public networks.
The calculator above estimates your personalized number — including Level 2 charger payback, time-of-use (TOU) savings, and the impact of battery degradation on a used EV. The rest of this page explains where those numbers come from and how to interpret them.
Key Takeaways
- At the US average of 18.83¢/kWh, home charging costs about $48/month for a 3.5 mi/kWh EV driving 10,787 miles/year.
- Charging at home costs roughly 5–7¢ per mile, versus about 10.3¢ per mile for a 30 MPG gasoline car at $3.10/gal.
- State rates range from about 11.5¢/kWh (Louisiana) to 46.6¢/kWh (Hawaii) — nearly a 4× difference.
- Time-of-use (TOU) plans can cut home charging costs by 30–60% if you charge overnight.
- A Level 2 charger usually costs $800–$1,500 installed and typically pays back in 2–6 years, depending on mileage and electricity price.
- Used EVs with reduced battery health use more energy per mile — a 15% SoH loss raises charging cost roughly 15–18%.
How Much Does It Cost to Charge an EV at Home?
Average US Cost
For a typical US driver using a mid-efficiency EV (roughly 3.5 mi/kWh) at the national average residential rate, home charging costs about $48 per month, or $580 per year.

How We Calculate Your EV Charging Cost
The Formula
Home charging cost is straightforward once you separate the pieces:
Annual home kWh = (annual miles × home charging share) ÷ vehicle efficiency Home charging cost = annual home kWh × electricity rate Cost per mile = total annual cost ÷ annual miles Gas cost = (annual miles ÷ gas MPG) × gas price
Efficiency here is expressed as miles per kWh (mi/kWh). If your vehicle's efficiency is listed as kWh per 100 miles, convert: mi/kWh = 100 ÷ (kWh/100 mi). A Tesla Model Y at 28 kWh/100 mi is 3.57 mi/kWh. A Ford F-150 Lightning at 48 kWh/100 mi is 2.08 mi/kWh.

|---|---|---|
| Electricity rates | EIA Electric Power Monthly | 18.83¢/kWh US average, April 2026 |
| Vehicle efficiency | EPA FuelEconomy.gov | Per-model, wall-to-wheel |
| Annual mileage | FHWA Highway Statistics | 10,787 miles (2024) |
| Gasoline price | EIA Short-Term Energy Outlook | $3.10/gal (2026 forecast) |
| Charger hardware | DOE Alternative Fuels Data Center | $380–$690 |
| Installation labor | DOE RSMeans (restated) | $400–$800 |
Charging Efficiency: Wall vs. Battery Energy
Charging loses 5–15% of the energy drawn from the wall before it reaches the battery (ENERGY STAR / Argonne National Lab). This matters because:
- Wall energy is what your utility meter records — the number you pay for.
- Battery energy is what the vehicle stores and uses to drive.
- EPA efficiency ratings are typically wall-to-wheel, meaning the charging loss is already included in the published mi/kWh figure.
Because of this, the calculator defaults the "real-world adjustment" to 100%. If you want a conservative estimate (accounting for cold weather, aggressive driving, or older batteries), lower it to 85–90%.
Assumptions and Defaults
- Annual mileage: 10,787 miles (FHWA national average).
- Charging efficiency: 100% (EPA wall-to-wheel basis).
- Home/public split: 100% home by default.
- Public DC fast charging rate: 35¢/kWh (mid-range US average).
- Battery health (used EV): 100% SoH by default.
- Level 2 charger installed cost: $1,100 (midpoint of DOE ranges).
- Gasoline comparison vehicle: 30 MPG at $3.10/gal.
Home Charging vs. Public Charging
Why Public Charging Costs 2–4× More
DC fast charging (Level 3) typically costs $0.35–$0.60/kWh versus $0.10–$0.35/kWh at home. The premium reflects:
- High-power equipment (150–350 kW chargers can cost $100,000+ per stall).
- Utility demand charges — commercial customers pay for peak power draw, not just total energy.
- Network operating costs (payment processing, support, maintenance).
- Site leasing and, in some cases, state electricity taxes.
The result: 100% public charging can erase most of the fuel savings versus gasoline. A 50/50 home/public mix typically lands around 8–10¢ per mile — roughly break-even with an efficient gasoline car.
When Public Charging Makes Sense
- Road trips where home charging isn't available.
- Apartment residents without dedicated home charging.
- Emergency top-ups when range is tight.
- Free or reduced-rate chargers at workplaces, hotels, or retail locations.
If more than about 20–30% of your annual miles require public charging, the cost savings versus gasoline narrow quickly. Model this with the home/public mix field in the calculator.
Time-of-Use (TOU) Rates: Are They Worth It?
How TOU Works
Many utilities offer plans where electricity costs less during off-peak hours (typically 9 PM to 6 AM) and more during peak hours (typically 4 PM to 9 PM). Because EVs charge overnight, they're an excellent fit for TOU plans.
Typical TOU rate structures:
| Plan Type | Off-Peak | Peak | Standard |
|---|---|---|---|
| Flat (baseline) | — | — | 18.83¢/kWh |
| Moderate TOU | 12¢/kWh | 35¢/kWh | — |
| Aggressive EV TOU | 7–9¢/kWh | 45–55¢/kWh | — |
How Much You Can Save
If you shift all EV charging to off-peak:
- At 12¢/kWh versus 18.83¢/kWh: saves about 36% on charging costs.
- At 8¢/kWh versus 18.83¢/kWh: saves about 58%.
On an annual basis, a driver spending $580/year on home charging could save $210–$335/year by switching to a TOU plan — provided the household doesn't shift more non-EV usage to peak hours.
How to Switch
- Log into your utility account and look for "rate options," "EV rate," or "time-of-use."
- Compare the off-peak rate against your current flat rate.
- Estimate your current household usage pattern — if you already run heavy appliances overnight, TOU may help; if you run AC or heat during peak, TOU may hurt.
- Most utilities allow a switch at the next billing cycle. Some require a smart meter (already installed for most US homes).
- Verify any enrollment fees or minimum-period commitments.
Solar + EV Charging: Reducing Your Cost to Near Zero
A typical US home solar array produces 8,000–12,000 kWh per year. Since a mid-efficiency EV uses about 3,000–4,500 kWh/year for average driving, a solar system can cover most or all of your vehicle's annual charging needs.
Key considerations:
- Self-consumption vs. export: Solar electricity used directly for EV charging is worth the full retail rate. Exported electricity is worth the net-metering rate, which is lower in many states.
- Timing: If you charge overnight (as most TOU plans encourage), your solar panels are not producing. You need battery storage or daytime charging to directly offset EV charging with solar.
- Net metering rules vary significantly by state and have changed in California, Nevada, and others in recent years. Verify with your utility.
The calculator's solar offset field lets you subtract solar production from your annual home charging kWh. It assumes self-consumption (no export credit modeling).
Level 2 Charger Payback: Is It Worth Installing?
Charger Costs
| Component | Typical Cost | Source |
|---|---|---|
| Level 2 hardware | $380–$690 | DOE AFDC |
| Installation (50A circuit) | $400–$800 | DOE RSMeans (restated) |
| Total installed | ~$800–$1,500 | — |
| Permit fees (varies) | $0–$300 | Local jurisdiction |
Home configuration matters. A detached garage with a long conduit run, an older electrical panel that needs upgrading, or a 100-amp service that requires a service upgrade can push costs above $2,500.
Federal Tax Credit
Historically, the Alternative Fuel Vehicle Refueling Property Credit (30C) has offered a 30% federal tax credit on home EV charger installation, up to $1,000, for eligible census tracts. Its status for the current and future tax years must be verified with the IRS or a qualified tax advisor before claiming.
If the credit applies to your installation:
- $1,100 installed × 30% = $330 credit → $770 net cost.
- Some states and utilities offer additional rebates that stack with the federal credit.
Verify current eligibility requirements — including census tract, income, and vehicle rules — with the IRS and your tax advisor.
Payback Calculation
Level 2 payback depends on how much more a Level 2 charger saves you versus a Level 1 (standard 120V outlet):
- Level 1 adds roughly 3–5 miles of range per hour. For a 40-mile daily commute, that's 8+ hours of charging.
- Level 2 adds 20–30 miles of range per hour. Charging overnight becomes feasible with minimal planning.
Because Level 1 is often sufficient for low-mileage drivers, the "payback" question is really about convenience and future-proofing, not just cost. Most Level 2 payback calculations use the fuel savings versus gasoline as the offset:
Payback (years) = Charger installed cost ÷ Annual fuel savings
For a driver saving $600/year on fuel with a $1,100 installed charger, payback is about 1.8 years. If the ITC applies, net cost is $770, and payback drops to about 1.3 years.
Used EV Battery Health and Charging Cost
A battery's state of health (SoH) measures how much capacity it has retained. Because a degraded battery must work harder to deliver the same miles, charging costs increase roughly in proportion to SoH loss:
| Battery SoH | Effective Efficiency | Relative Charging Cost |
|---|---|---|
| 100% | 3.50 mi/kWh | Baseline (1.00×) |
| 90% | 3.15 mi/kWh | +11% |
| 80% | 2.80 mi/kWh | +25% |
| 70% | 2.45 mi/kWh | +43% |
Real degradation curves are not linear and vary by battery chemistry, thermal management system, climate, and charging habits. Below 70% SoH, some manufacturers will replace the battery under warranty; most warranties cover 8 years or 100,000 miles to 70% capacity, whichever comes first.
If you are considering a used EV, request a battery health report (from the manufacturer app or a third-party service) and use the SoH field in the calculator to see the impact on annual charging cost.
Frequently Asked Questions
How much does it cost to charge an EV at home?
At the US average residential rate of about 18.83¢/kWh and average driving of 10,787 miles per year, expect roughly $45–$80 per month depending on your vehicle's efficiency. Efficient sedans sit near the low end; large trucks and SUVs near the high end.
Is charging at home cheaper than gasoline?
For most US drivers, yes. Home charging typically costs 5–7¢ per mile; a 30 MPG gasoline car at $3.10/gal costs about 10.3¢ per mile. In high-rate states like Hawaii and California, the gap narrows or disappears unless you charge on an off-peak TOU plan.
How much does a Level 2 charger cost to install?
Hardware runs $380–$690, and installation for a standard 50-amp circuit runs $400–$800, totaling roughly $800–$1,500 before any incentives. Complex installations — long conduit runs, panel upgrades, or detached garages — can exceed $2,500.
Does charging an EV increase my electric bill?
Yes, by roughly the amount estimated by a home charging calculator — typically $40–$80 per month for average driving. Because EV charging is a large, predictable load, many utilities offer dedicated EV rate plans that can reduce the increase by 30–60% when charging overnight.
What is the cheapest time to charge an EV?
Overnight, typically between 9 PM and 6 AM, when utilities offer off-peak rates on time-of-use plans. Off-peak rates are commonly 40–70% lower than peak. Some utilities also offer "super off-peak" windows (usually 11 PM to 5 AM) at even lower rates.
How much does it cost to fully charge a Tesla Model Y at home?
A Tesla Model Y Long Range has roughly a 75 kWh usable battery. At the US average of 18.83¢/kWh, a full charge costs about $14.12. At California's 35.25¢/kWh, it's about $26.44; at Louisiana's 11.50¢/kWh, it's about $8.63. These figures assume 100% charging efficiency; wall-to-battery losses of 5–15% add to the actual cost.
What is the cost per mile for an EV?
For a mid-efficiency EV at US average rates, home charging costs about 5.4¢ per mile. An efficient sedan is closer to 4.7¢/mi; a large truck is closer to 7.5¢/mi. Public DC fast charging is 2–4× higher and can approach gasoline cost parity.
How do I calculate EV charging cost with TOU rates?
Multiply your off-peak rate by your annual kWh if you charge entirely overnight. If you split between peak and off-peak, weight each by its share. The calculator's TOU off-peak and peak rate fields handle this automatically and show annual savings versus a flat rate.
Should I switch to a time-of-use plan?
If you can charge your EV overnight and your household's other electricity use doesn't spike during peak hours, TOU plans usually save money. If you use significant electricity during peak hours (electric heating, air conditioning, evening cooking), the savings may be smaller or negative. Compare your specific usage pattern before switching.
How does used EV battery health affect charging cost?
A battery at 80% state of health delivers fewer miles per kWh, so each mile costs more. A rough estimate: a 10% SoH loss raises charging cost roughly 11%, and a 20% loss raises it about 25%. Real degradation is not perfectly linear and varies widely by model and climate.
How accurate is this calculator?
It provides a personalized estimate based on your inputs and published government data. Actual costs vary with real-world efficiency, seasonal rate changes, driving conditions, and the specific tariff your utility applies. Treat the result as a planning figure, not a utility bill prediction.
Can solar panels eliminate my EV charging cost?
Partially or fully, depending on system size and driving. A typical 8,000–10,000 kWh/year array can cover most of an average EV's annual charging needs. Timing matters: unless you have battery storage or charge during daylight hours, your solar production and EV charging may not directly offset each other on the meter.
