EV Cost Per Mile Calculator: See Your Real Cost to Drive Electric in 2027
The average electric vehicle costs roughly 3–5 cents per mile to charge at home in the United States, compared with approximately 10–15 cents per mile for a typical gasoline car at current fuel prices and fuel economy. Your exact cost depends on three things: the electricity rate in your state, your vehicle’s efficiency, and how much of your charging happens at home versus public stations.
Use the calculator above to enter your state and vehicle for a personalized estimate. The sections below explain how the math works, why home and public charging produce such different numbers, and which assumptions matter most.
Key Takeaways
- Home charging typically costs 3–5¢ per mile in most US states; DC fast charging can cost 10–20¢ per mile or more.
- EV cost per mile is driven by three inputs: electricity rate ($/kWh), vehicle efficiency (mi/kWh), and charging mix.
- Adding roughly 10% for charging losses brings estimates closer to real utility-bill reality.
- Gas vehicles typically cost 10–15¢ per mile at $3.00–$4.50 per gallon and 25–35 MPG.
- Public DC fast charging can occasionally cost more per mile than gasoline, especially in high-electricity-rate states.
- State electricity rates range from roughly 11¢/kWh (Washington) to over 40¢/kWh (Hawaii).
- Time-of-use rates, winter efficiency loss, and home solar can materially change your actual number.
How to Calculate EV Cost Per Mile
EV cost per mile is the amount you pay for electricity divided by the number of miles you drive on that electricity. In practice, most drivers want to know two numbers: the cost per mile on home charging, and the cost per mile on public charging.
The Formula
At its simplest, cost per mile is:
Cost per mile = Electricity rate ($/kWh) ÷ Vehicle efficiency (mi/kWh)
With charging losses included (typically around 10% for Level 2 home charging), the formula becomes:
Cost per mile = (Electricity rate ÷ Efficiency) × (1 + Charging loss %)
Example: In a state where electricity costs $0.15 per kWh and your EV gets 3.5 miles per kWh, home charging costs $0.15 ÷ 3.5 = $0.0429 per mile, or about 4.3¢ per mile before charging losses and about 4.7¢ per mile with a 10% charging loss.
If you mix home and public charging, the blended cost is a weighted average of each:
Blended cost = (Home % × Home cost) + (Public % × Public cost)
What Electricity Rate Should I Use?
Your electricity rate is the price you pay per kilowatt-hour (kWh), found on your utility bill. Residential rates in the US vary widely by state and by utility within a state. National averages mask a range of roughly 11¢ to over 40¢ per kWh for residential customers.
The calculator above uses a state-level approximate default based on EIA residential rate data. You should override it if:
- You are on a time-of-use (TOU) plan, where off-peak EV charging can be 30–60% cheaper than the standard rate.
- You have home solar, which changes your effective cost per kWh.
- Your utility charges a different rate than the state average.
For a defensible number, take your utility bill’s effective rate (total bill ÷ total kWh) rather than the headline rate.
What Efficiency Rating Should I Use?
Vehicle efficiency is measured in miles per kWh (mi/kWh). The EPA Fuel Economy Guide lists efficiency for every EV sold in the US. Typical values:
- Efficient sedans: 3.5–4.5 mi/kWh (e.g., Tesla Model 3 RWD, Hyundai Ioniq 6)
- Crossovers and small SUVs: 3.0–3.8 mi/kWh (e.g., Tesla Model Y, Hyundai Ioniq 5)
- Large SUVs and trucks: 1.6–2.5 mi/kWh (e.g., Rivian R1T, Ford F-150 Lightning, GMC Hummer EV)
Real-world efficiency typically runs 10–20% lower than the EPA figure, especially in cold weather, at highway speeds, or with aggressive driving. The EPA rating is a useful benchmark but is not a guarantee.
EV Cost Per Mile by State
Electricity rates vary significantly by state, which means EV cost per mile varies too. The table below shows approximate residential rates and resulting home-charging cost per mile for an EV that achieves 3.5 mi/kWh (with a 10% charging loss). Treat these as estimates — verify your own rate on your utility bill before making financial decisions.
| State | Approx. Residential Rate (¢/kWh) | Approx. Home Cost per Mile (¢) |
|---|---|---|
| Washington | ~11 | ~3.5¢ |
| Louisiana | ~12 | ~3.8¢ |
| Idaho | ~12 | ~3.8¢ |
| Texas | ~14 | ~4.4¢ |
| Florida | ~15 | ~4.7¢ |
| Illinois | ~15 | ~4.7¢ |
| Colorado | ~14 | ~4.4¢ |
| Georgia | ~13 | ~4.1¢ |
| Ohio | ~15 | ~4.7¢ |
| Arizona | ~15 | ~4.7¢ |
| New York | ~22 | ~6.9¢ |
| Pennsylvania | ~17 | ~5.3¢ |
| New Jersey | ~18 | ~5.7¢ |
| Michigan | ~17 | ~5.3¢ |
| Massachusetts | ~27 | ~8.5¢ |
| Connecticut | ~25 | ~7.9¢ |
| California | ~29 | ~9.1¢ |
| Alaska | ~24 | ~7.5¢ |
| Hawaii | ~42 | ~13.2¢ |
Note: Rates shown are approximate 2026 averages for illustration. Actual residential rates vary by utility and rate plan. Verify your own rate with your utility or the EIA Electric Power Monthly.
Home vs. Public Charging: Cost Per Mile Comparison
One of the most common surprises for new EV owners is how much more expensive public charging can be. The difference is not minor.
Why Home Charging Is Cheaper
Residential electricity is the cheapest common way to charge an EV. Utilities charge residential customers a retail rate that reflects generation, transmission, and distribution costs — but no retail markup or network fee.
When Public Charging Costs More Than Gas
Public DC fast charging can cost substantially more per mile than home charging, and in some cases more than gasoline. Reasons include:
- Public charging networks charge per kWh at a premium to cover equipment, site lease, demand charges, and card processing.
- Some states price DC fast charging by the minute rather than by kWh, which penalizes slower-charging vehicles.
- In high-electricity-rate states (California, Hawaii, Massachusetts), DC fast charging can exceed $0.60/kWh.
At $0.50/kWh and 3.5 mi/kWh, public charging costs about 15.7¢ per mile with charging loss — comparable to or higher than a 30 MPG gas car at $3.50/gallon (11.7¢ per mile). This is the core reason why home charging access is the single biggest determinant of EV operating economics.
EV vs. Gas: Which Costs Less Per Mile?
For most US drivers with home charging, an EV costs less per mile than a comparable gas vehicle. The gap narrows or reverses under specific conditions.
National Comparison
- EV (home charging): roughly 3–6¢ per mile at $0.12–$0.20/kWh and 3.0–4.0 mi/kWh.
- EV (public DC fast only): roughly 12–20¢ per mile at $0.40–$0.60/kWh.
- Gas car at 30 MPG: roughly 10–15¢ per mile at $3.00–$4.50/gallon.
- Hybrid at 50 MPG: roughly 6–9¢ per mile at the same gas prices.
State-Level Variations
State electricity rates and gas prices do not move together. Hawaii has the highest electricity rate in the country — but also some of the highest gas prices — so the EV advantage narrows but does not disappear. Washington has both cheap electricity and expensive gas, so the EV advantage is largest there. In California, both are expensive, but home-charging EVs still typically beat gasoline on a per-mile basis.
Breakeven Analysis
The breakeven gas price is the gasoline price at which an EV and a gas car cost the same per mile. At a blended EV cost of 5¢ per mile and a 30 MPG gas car:
Breakeven gas price = EV cost per mile × Gas MPG = $0.05 × 30 = $1.50/gallon
At any gas price above $1.50/gallon, the EV is cheaper per mile under these assumptions. Because US gasoline has not been below $1.50/gal nationally since the early 2020s, this illustrates why home-charged EVs are almost always cheaper on fuel. Public-charging-only scenarios are far less favorable.
What Affects Your EV Cost Per Mile?
Electricity Rate
This is the single largest variable. A 10¢/kWh difference changes the per-mile cost by roughly 3¢ at 3.5 mi/kWh. Time-of-use plans, solar, and utility choice can all change your effective rate.
Vehicle Efficiency
Efficiency varies by 2× or more across the EV market. A Lucid Air (about 4.0 mi/kWh) uses half the electricity per mile of a GMC Hummer EV (about 1.6 mi/kWh). Choosing an efficient EV is one of the most effective ways to reduce operating cost.
Charging Losses
Not all electricity drawn from the wall reaches the battery. Level 2 home charging typically loses around 10%; Level 1 (120V) can lose 15–20%; DC fast charging loses less during the session but can incur higher upstream losses. Including this factor makes estimates match reality more closely.
Driving Conditions (Winter, Terrain)
Cold weather reduces range by 20–30% on many EVs, primarily from cabin heating and battery chemistry effects. Hills, high speeds, and heavy payloads also reduce efficiency. The EPA rating does not fully capture these variations.
Regenerative Braking
Regenerative braking recovers energy during deceleration and is already accounted for in the EPA efficiency rating. Its benefit is highest in stop-and-go city driving and lowest on the highway.
Frequently Asked Questions
How do you calculate EV cost per mile?
Divide your electricity rate in dollars per kWh by your vehicle’s efficiency in miles per kWh. For example, $0.15/kWh ÷ 3.5 mi/kWh = about 4.3¢ per mile. Add roughly 10% for charging losses to approximate your actual utility-bill cost.
What is the average cost per mile for an EV?
For home charging in the US, most drivers see roughly 3–6¢ per mile depending on state electricity rates and vehicle efficiency. Public DC fast charging typically ranges from 12–20¢ per mile.
Is an EV cheaper per mile than gas?
For most drivers with access to home charging, yes — usually by a factor of 2–3×. If you rely exclusively on public DC fast charging, the advantage shrinks and can disappear in high-rate states.
How much does it cost to charge an EV per mile?
Home charging typically costs 3–6¢ per mile. Public Level 2 charging is usually 6–12¢ per mile. Public DC fast charging is usually 12–20¢ per mile. Rates vary significantly by state and network.
What electricity rate should I use for my EV?
Use the effective rate from your utility bill (total bill ÷ total kWh), not the headline rate. If you are on a time-of-use plan, use your off-peak rate since most EV charging happens overnight.
Does public charging cost more than gas?
Sometimes. In high-electricity-rate states or at premium DC fast charging networks, public charging can exceed the per-mile cost of gasoline. This is why home charging access is the biggest factor in EV ownership economics.
How does winter affect EV cost per mile?
Cold weather reduces range by 20–30% on many EVs. That translates to a proportional increase in cost per mile — a 4¢/mile summer cost can become 5–6¢/mile in deep winter. Cabin preconditioning while plugged in helps reduce the penalty.
What is a good mi/kWh for an EV?
Above 4.0 mi/kWh is efficient. Between 3.0 and 4.0 mi/kWh is typical for sedans and crossovers. Below 2.5 mi/kWh is common for large trucks and SUVs. Real-world values typically run 10–20% lower than the EPA rating.
Does the EPA efficiency rating include charging losses?
The EPA rating is measured at the wall (accounting for some charging losses during testing), but real-world losses vary by charger type and conditions. Adding an explicit 10% loss factor is a conservative approach that many analysts use.
How does regenerative braking affect cost per mile?
Regenerative braking is already included in the EPA efficiency rating. Its benefit is greatest in city driving. There is no additional calculation needed for most users.
