EV Home Charging Cost per Mile vs Gas — The 2026 Math

EV ownership has gotten complicated with all the noise flying around — half the internet says you’ll save thousands, the other half says you’re fooling yourself. As someone who’s been driving a 2022 Chevy Bolt EUV out of Tacoma for two years, charging almost exclusively on a Level 2 ChargePoint Home Flex in my garage, I learned everything there is to know about what this actually costs in the real world. And I mean that literally — I went back and audited my old bank statements because I didn’t trust my own memory. Turns out I was right. Compared to filling my old 2019 Honda CR-V, I’m saving somewhere between $80 and $90 every single month. Over a year, that’s not “skip your coffee” money. That’s actual, meaningful money.

What follows is the 2026 math — national averages first, then Pacific Northwest specifics, then the charging location breakdown most people skip entirely, and finally the maintenance picture that makes the whole thing even more lopsided. If you’re in Washington or Oregon and still on the fence, this might be the piece that settles it.

The National Math — EV Wins by Half

Start with the headline number, because it’s striking. Across the U.S. in 2026, the average EV costs roughly 4 cents per mile to drive. The average gas car? Around 13 cents per mile. That’s not a rounding error. That’s a 69% reduction in per-mile fuel cost.

Here’s what that looks like month to month. The average American drives 1,200 to 1,300 miles monthly — call it 1,250 for the math:

• Gas car at 13 cents per mile — $162.50 per month
• EV at 4 cents per mile — $50.00 per month
• Monthly savings — $112.50
• Annual savings — $1,350

Some widely-cited estimates put EV charging closer to $61 per month against $132 for gas — slightly lower mileage assumptions, blended efficiency across the current fleet. Either way, you’re looking at $70 to $112 in monthly savings. $840 to $1,500 per year. Your exact number shifts based on your vehicle, your local gas price, and how you’re charging.

The 13-cents-per-mile gas figure assumes roughly 28 MPG and a national average gas price around $3.60 to $3.70 per gallon — a reasonable 2026 projection. The 4-cents-per-mile EV figure assumes a residential electricity rate of about 16 cents per kWh and real-world efficiency of 3 to 3.5 miles per kWh. That tracks pretty closely with popular models — the Tesla Model 3, the Hyundai Ioniq 6, the Chevy Bolt.

Solid averages. But national averages hide enormous regional variation — and that variation is what actually determines your electricity bill after you plug in at your garage in Bellingham or Portland.

Pacific Northwest Rates Make It Even Better

Probably should have opened with this section, honestly. This is what most national comparison pieces completely miss, and it’s the most important part for anyone reading from Washington or Oregon.

The Pacific Northwest runs on some of the cheapest residential electricity in the entire country. Hydroelectric power from the Columbia River system — Bonneville Dam, Grand Coulee, and a dozen others — keeps rates well below the national average. Here’s what that actually means in numbers you can use.

Washington State Rates

Puget Sound Energy customers in 2026 are paying around 10 to 11 cents per kWh in the first residential tier. Seattle City Light comes in even lower — around 9 to 10 cents per kWh. Snohomish County PUD lands in that same 9 to 10 cent range. All of them meaningfully below the 16-cent national average.

Run the EV math at a 10-cent rate:

• Bolt EUV gets roughly 3.5 miles per kWh in real-world driving
• At 10 cents per kWh, that works out to 2.86 cents per mile — call it 3 cents per mile
• At 1,250 miles per month, that’s $37.50 per month to charge

Now compare that $37.50 to what a 28-MPG gas car costs in Washington — where gas has been running $3.80 to $4.00 per gallon in the Puget Sound region through 2025 and into 2026. At $3.90 per gallon and 28 MPG, those same 1,250 miles cost $174 in gas.

That’s a gap of $136.50 per month in Washington. $1,638 per year.

Oregon Rates

Oregon is slightly less dramatic — but still well below the national average. Portland General Electric customers pay around 11 to 12 cents per kWh. Pacific Power comes in around the same range. Eugene Water & Electric Board sits among the cheapest in the state, around 9 to 10 cents. Oregon gas prices track close to Washington’s — Portland usually lands around $3.70 to $3.90 per gallon depending on the month.

At 12 cents per kWh and 3.5 miles per kWh, Oregon EV drivers are paying about 3.4 cents per mile. Gas at $3.80 and 28 MPG runs about 13.6 cents per mile. That’s still a four-to-one ratio in favor of electricity.

Portland EV drivers are saving roughly $125 per month versus a comparable gas car. Around $1,500 per year.

A Word on Time-of-Use Rates

Both PSE and PGE offer time-of-use plans — and they reward overnight charging with rates that drop even further. PSE’s EV-specific plan falls to around 6 to 8 cents per kWh during off-peak overnight hours. Set your charger to kick on at midnight and finish by 6 a.m. — trivially easy with basically every Level 2 home charger on the market — and your per-mile cost drops to 2 cents or under. At that point, you’re essentially driving on rounding errors.

I switched to PSE’s time-of-use plan about eight months into ownership. Dropped my charging cost another $12 to $15 per month. Small number — but it’s money for doing essentially nothing.

Home Charging vs Public Charging Cost Difference

But what is charging cost, really? In essence, it’s whatever rate you pay per kWh times how much energy your car actually uses. But it’s much more than that — because where you charge determines your cost more than which EV you drive. This isn’t a footnote. It’s a foundational point that changes the entire economics of owning one of these cars.

Home Level 2 Charging — The Gold Standard

Charging at home on a Level 2 setup — a 240-volt charger, typically a 32- or 48-amp unit like the ChargePoint Home Flex, the Wallbox Pulsar Plus, or the Emporia EV Charger — gives you access to your utility’s residential rate. In the PNW, that’s 9 to 12 cents per kWh. That’s where the 2 to 3 cents per mile figures come from.

The upfront cost runs $400 to $700 for the unit, plus $200 to $600 for an electrician depending on your panel and garage setup. Total, call it $600 to $1,300 one-time. Most PNW drivers recoup that within 6 to 12 months in pure fuel savings.

Public Level 2 Charging — Moderate Cost

Public Level 2 stations — grocery stores, libraries, office parking garages — charge by the hour or by the kWh. Blink and ChargePoint in the Pacific Northwest typically run $0.10 to $0.20 per kWh at public Level 2 stations, or $1 to $2 per hour. Still cheaper than gas, but noticeably more than home charging. Figure 5 to 6 cents per mile in the PNW.

Use home charging as your baseline and public Level 2 as a top-up, and your blended rate stays very low.

DC Fast Charging — The Trap

Don’t make my mistake. DC fast charging — the kind that adds 100 miles in 20 to 30 minutes — is significantly more expensive per kWh than home charging. Electrify America stations in Washington and Oregon are currently pricing at $0.43 per kWh for non-members. Tesla Superchargers outside a membership plan run $0.40 to $0.48 per kWh.

At $0.43 per kWh and 3.5 miles per kWh, you’re paying 12.3 cents per mile. That’s almost exactly what gas costs in a 28-MPG car at $3.45 per gallon. At $0.48 per kWh, you’re at 13.7 cents per mile — more expensive than gas, full stop.

I got burned by this on a road trip down to Eugene — hadn’t set up a membership plan yet, so I was paying Electrify America’s casual rate the whole way. Actively getting worse cost-per-mile than my old CR-V would have. Lesson learned the hard way: set up the membership tier on whatever fast charging networks you use regularly. It typically drops the per-kWh rate to $0.25 to $0.32 — back to 7 to 9 cents per mile. Not as good as home charging, but reasonable for road trips.

Home charging is your baseline. Public Level 2 is acceptable. DC fast charging is for road trips and genuine emergencies — not a daily strategy.

The Full Cost Picture — Maintenance Saves Too

That’s what makes the PNW EV case so endearing to us number-crunchers — even the fuel math alone is compelling, and maintenance adds another layer on top of it.

Oil Changes Gone

The average American spends $120 to $200 per year on oil changes — more if they’re in a truck or a European car. EVs have no engine oil. No filter. No oil change. Ever. That’s $120 to $200 back annually, with no math required.

Synthetic oil changes for my old CR-V at the Honda dealer ran $89.95 every 6,000 miles. Four of those per year. $360 per year — gone the day I picked up the Bolt.

Brake Pads Last Two to Three Times Longer

Regenerative braking — the system that recaptures energy when you lift off the throttle — means the friction brakes on an EV barely engage in normal driving. Brake pads on a Bolt EUV, a Model 3, or an Ioniq 6 routinely last 80,000 to 100,000+ miles. Gas car pads typically wear out at 30,000 to 50,000 miles depending on how you drive.

A front brake job on a typical gas car runs $250 to $400. Do it once every 40,000 miles on a gas car versus once every 100,000 miles on an EV, and over a 200,000-mile lifespan the savings are substantial. Figure $600 to $800 in brake savings across the life of the vehicle.

The Transmission, the Coolant, the Spark Plugs

EVs have no transmission fluid to change. No spark plugs. No timing belt, no serpentine belt. The maintenance schedule on a Bolt EUV is almost embarrassingly short — tire rotations, cabin air filter, wiper blades. Roughly it for the first 100,000 miles. The 30,000-, 60,000-, and 90,000-mile service intervals that add up to $800 to $1,200 on a gas car simply don’t exist.

Third-party studies have consistently found EV maintenance costs running 30 to 40 percent lower than equivalent gas vehicles over a five-year ownership period. Consumer Reports data from 2023 and 2024 pegged EV maintenance at about $0.031 per mile versus $0.061 per mile for gas — another 3 cents per mile in the EV column.

The Total Cost of Ownership — PNW Edition

Add it all together for a Pacific Northwest driver doing 15,000 miles per year:

• Fuel savings — $1,400 to $1,600 per year
• Oil change elimination — $120 to $360 per year
• Reduced maintenance (brakes, transmission service, plugs) — $200 to $400 per year amortized
• Total annual savings — $1,720 to $2,360 per year

At $2,000 per year in combined savings, an EV pays down its purchase price premium — typically $3,000 to $6,000 over a comparable gas vehicle before credits — in 1.5 to 3 years. With the federal EV tax credit holding at $7,500 for qualifying vehicles and buyers in 2026, many PNW buyers end up in a position where the EV is cheaper to purchase outright, then cheaper to run every single month after that.

That’s not a marginal win — that’s a structural cost advantage that compounds the longer you own the car. If you live in Washington or Oregon, charge primarily at home, and drive a normal number of miles per year, the 2026 math lands pretty clearly. The national numbers already favor EVs. The PNW numbers make the argument almost unanswerable.
