Electric Vehicle Charging by State: Cheapest and Most Expensive

The cost to charge an Electric Vehicle (EV) can differ dramatically from one state to another. That’s because retail electricity prices, utility rate structures, and public charging fees vary by region. If you’re planning a move, comparing commute costs, or just curious how your state stacks up, this guide breaks down the drivers of price differences and shows how to estimate your own costs anywhere in the U.S.

Why Prices Vary

Electric rates reflect a blend of generation mix, transmission costs, local regulations, and utility investments. States with abundant hydro, wind, or solar often enjoy lower residential rates, while regions reliant on imported fuels or legacy infrastructure may pay more. Local taxes and fees also play a role. On the public charging side, station operators set prices based on demand, real estate costs, and network fees—so two stations across town might charge different rates.

Home vs. Public Charging

Home charging is almost always the cheapest option—especially on Time-of-Use (TOU) plans that discount overnight power. Public Level 2 chargers can still be cost-effective if they are free or subsidized by workplaces or municipalities. DC fast charging is the most expensive but is invaluable for long trips and occasional top-ups. When comparing states, evaluate each of these channels, not just the average residential rate.

Estimating Your Cost per Mile

A simple way to compare states is to calculate cost per mile. Take your electricity price ($/kWh) and your EV’s efficiency (kWh per 100 miles). Divide to get $/mile. For example, at $0.15/kWh and 28 kWh/100 miles, you’re paying about $0.042/mile. If another state averages $0.25/kWh, the same car would cost ~$0.07/mile—about 67% more for identical driving.

What to Watch in Your State

Off-Peak Discounts: Look for TOU plans with deep overnight savings. Some utilities add EV-only plans with super off-peak rates.
Demand Charges: A few public networks price by the minute or add session fees. Compare the total cost, not just the headline rate.
Local Incentives: States and utilities may offer rebates for home chargers or bill credits for EV enrollment—effectively lowering your cost to charge.
Apartment Charging: If you don’t have a garage, check for workplace or community Level 2 options; some states push grants to add them.

How to Use This Information

Instead of focusing on a single “cheap” or “expensive” ranking, build a personal profile: your state’s overnight rate, your daily mileage, whether you can charge at work, and how often you use fast charging. Plug those inputs into the calculator on our homepage and you’ll get a clear, state-adjusted picture that’s far more useful than a generic national average.

Bottom Line

States differ, but smart charging strategies narrow the gap. Combine an EV-friendly rate plan with mostly home charging and you’ll enjoy low, predictable per‑mile costs—no matter where you live.
