EV Charging Cost by State: The Full 50-State Table (2026)

The table below converts each state’s average residential electricity rate into two practical numbers: what 100 miles of driving costs, and what a “fill-up” of a typical 70 kWh battery costs from empty. States are sorted from cheapest to most expensive EV charging cost.

Rates: U.S. Energy Information Administration, May 2026 average residential prices. Efficiency assumption: 3 miles per kWh (33.3 kWh per 100 miles) — a realistic mixed-driving figure for mainstream EVs.

How We Calculated These Numbers

Every EV charging cost figure above comes from one formula, so you can redo it with your own utility bill:

Cost per 100 miles = your electricity rate (¢/kWh) × 33.3 kWh ÷ 100

We use 3 miles per kWh because it is honest for real-world driving. EPA window stickers often imply 3.3–4 mi/kWh, but winter temperatures, highway speeds and cabin heating pull most drivers down toward 2.8–3.2. An efficient sedan like a Tesla Model 3 or Hyundai Ioniq 6 will beat our numbers; a heavy truck like an F-150 Lightning (closer to 2 mi/kWh) will cost about 50% more per mile than the table shows. If you want the official label figures instead, our longest range electric cars table lists every 2026 EV’s EPA range and kWh per 100 miles.

The 70 kWh full-charge column assumes charging from 0% to 100% of a typical mid-size pack. In practice you’ll rarely do that — most owners charge daily between 30% and 80%, so a routine overnight session costs a third to half of the full-charge figure. Add roughly 8–12% on top for charging losses between the wall and the battery — our home EV charging guide explains where those losses come from.

Why EV Charging Cost Varies 4× Between States

The spread in the table isn’t random — it tracks three structural factors:

• Generation mix. The cheapest tier (Idaho 12.35¢, Utah 12.96¢, Washington 14.95¢) leans on hydropower that was paid off decades ago. Hawaii’s 52¢ rate reflects an island grid still burning imported petroleum for a large share of generation.
• Transmission and distribution costs. New England states (Massachusetts 28.82¢, Maine 28.63¢, Connecticut 27.37¢) pay heavily for grid upkeep and constrained natural-gas pipelines, not just for the electrons themselves.
• Market structure and policy. California’s 33.25¢ average bundles wildfire-mitigation spending and social programs into rates — which is exactly why its utilities offer some of the country’s steepest EV-specific off-peak discounts as a pressure valve.

The practical read: if you live in the expensive tier, the rate on the table is your worst case, and the TOU section below matters more to you than to anyone else.

Home Charging vs Public DC Fast Charging

Everything above assumes charging at home on a Level 2 charger — the cheapest way to run an EV. Public DC fast charging is a different economy:

At typical published network prices, DC fast charging costs more per mile than gasoline in cheap-electricity states — which surprises many new owners. The pattern that keeps your overall EV charging cost low is simple: home for routine, fast chargers for travel. Our EV charging stations guide breaks down each network’s pricing and membership math, and the Level 2 charger guide covers picking home equipment.

The per-kWh price is not the whole public-charging bill either. Fixed session fees and post-charge idle fees sit on top of it, and on a small top-up a fixed fee can outweigh the difference between a cheap state and an expensive one — see what the networks publish about EV charging idle fees.

Time-of-Use Rates: The Biggest Lever on Your EV Charging Cost

Most utilities now offer time-of-use plans that price overnight electricity far below the daytime rate — because an EV that charges at 2 a.m. uses grid capacity nobody else wants. The discounts are not small:

• A typical TOU spread puts off-peak at 30–50% below the standard rate, with some EV-specific plans dipping under 10¢/kWh overnight even in mid-priced states.
• Worked example: a Colorado driver at the state’s 16.16¢ average pays about $5.38 per 100 miles. On an EV plan with a 9¢ overnight rate, the same 100 miles costs $3.00 — a 44% cut for changing nothing but the charging schedule.
• Every modern EV and smart charger can schedule charging automatically; you set the window once and forget it.

The catch to check before switching: TOU plans raise daytime prices for the whole household. If someone runs air conditioning all afternoon, do the math on the full bill, not just the car. Our guide to charging times and grid emissions has the bonus angle: the cheap overnight hours are often (though not always) the cleaner ones too.

EV Charging Cost vs Gasoline: State by State Logic

Run the same 100-mile math on a gasoline car and the comparison becomes concrete. A 30-mpg car needs 3.33 gallons per 100 miles:

This is why the “is charging really cheaper?” question has a boring answer for home charging: yes, essentially everywhere, usually by half. The honest caveats: rely mostly on DC fast charging and the advantage shrinks toward zero; drive an inefficient EV in a 25¢+ state and a 40-mpg hybrid gets close. For the full lifetime picture — purchase price, maintenance, resale — see our charging vs gas deep dive and cheapest electric cars guide.

Regional Patterns: Where the Grid Is Kind to EVs

Zoom out from the state table and four clear regions emerge, each with its own EV charging cost story:

• Pacific Northwest and Mountain West (12–16¢). Legacy hydropower and cheap land for wind make Idaho, Utah, Washington, Montana and Wyoming the best places in America to fuel on electrons. An EV here runs on roughly $0.04 per mile.
• South and Central states (13–17¢). Oklahoma, Nebraska, Louisiana, Missouri and Texas combine cheap natural gas with growing wind. Texas deserves a note: its deregulated market means the 16.44¢ average hides plans ranging from under 10¢ to over 20¢ — shopping your retail provider matters more there than in any other state.
• Northeast (21–30¢). Massachusetts, Connecticut, Rhode Island, New York and Maine pay the country’s highest grid costs. EV charging cost still beats gasoline here, but the margin is thinner, and TOU enrollment is close to mandatory for good economics.
• The islands and isolated grids (28–52¢). Alaska and especially Hawaii pay for imported fuel and small, isolated grids. Ironically Hawaii is also where rooftop solar pairs best with an EV — sunshine is the one fuel the islands have in surplus.

One structural trend to watch: rates have been climbing roughly 6% year over year nationally, driven by grid-modernization spending and data-center demand growth. That lifts the whole table over time — but it lifts gasoline’s competing costs too, and TOU spreads have been widening, not narrowing, as utilities court overnight EV load.

No Home Charger? How the Math Changes

Roughly a third of American drivers — apartment and condo residents, street parkers — can’t charge at home, and for them the state table above is aspirational. Their realistic EV charging cost mix looks different:

• Workplace Level 2, where available, is the anchor: often free or lightly subsidized, it can cover most commuting miles.
• Public Level 2 at $0.20–0.30/kWh or hourly pricing lands between home and fast-charging costs — fine for topping up during errands.
• Fast-charging memberships become the routine rather than the exception, pushing effective costs to $0.30–0.45/kWh even with discounts.

The blended result typically runs 1.5–2.5× the home-charging figures in our table — still competitive with gasoline in cheap and mid-priced states, but marginal in the Northeast. If this is your situation, prioritize an EV with efficient charging curves and check whether your city or utility runs curbside-charging programs before committing.

Seven Ways to Lower Your EV Charging Cost

1. Switch to a TOU or EV-specific rate plan. The 30–50% saving above — one phone call or web form.
2. Schedule charging in the car, not the charger. Every EV has a departure/charge-window setting; it costs nothing.
3. Charge to 80% for daily use. The last 20% charges slowly and inefficiently; skipping it trims losses and helps the battery.
4. Use workplace or destination Level 2 when it’s free. Hotels, offices and grocery stores still subsidize charging as an amenity.
5. Buy network memberships before road trips. Typical member pricing cuts fast-charging rates by 20–25% for a small monthly fee — worth it from about two sessions per month.
6. Precondition while plugged in. Heating or cooling the cabin on wall power instead of battery power effectively moves those kWh to your cheap home rate.
7. Check for utility EV rebates. Many utilities offer $50–$500 for enrolling in managed-charging programs — and see our EV incentives guide for what remains at the federal and state level.

Worked Examples: Three Real Households

Formulas are abstract; annual bills are not. Here is the EV charging cost math for three typical situations, using the table’s rates and 12,000 miles per year (4,000 kWh at 3 mi/kWh):

1. Missouri commuter, standard rate. At 13.68¢/kWh, the year costs 4,000 × $0.1368 = $547. The same miles in a 30-mpg gas car at $3.20 need 400 gallons = $1,280. The EV saves $733 a year without touching a single setting — a low EV charging cost is simply the default in the cheap-power belt.

2. Massachusetts family, TOU plan. The scary 28.82¢ average would mean $1,153 a year — the country’s second-highest home EV charging cost. But on an EV rate with 15¢ overnight charging, the same 4,000 kWh costs $600. Gasoline for those miles at $3.30: $1,320. The TOU enrollment, one web form, was worth $553 a year; skipping it would have surrendered most of the EV’s fuel advantage.

3. Texas road-tripper, mixed charging. 9,000 home miles at 16.44¢ cost $493; 3,000 fast-charging miles at a member rate of 40¢/kWh cost $400. Total: $893 — an effective 22¢/kWh blended rate. The one-quarter of miles done on fast chargers produced nearly half the bill, which is the cleanest illustration of why the home-vs-network split dominates your real EV charging cost more than your state does.

Run your own version: (annual miles ÷ 3) × your rate for the home share, then add fast-charging sessions at your network’s published price. If the total beats your current annual fuel spend by less than $300, look at TOU enrollment before blaming the car.
