Most articles on EV charging cost quote national averages, but those only give a rough starting point and won't match your bill. Your own spend depends on how efficient your vehicle is, how your utility structures its rates, and whether you charge during a cheap overnight window or an expensive peak one. Below is the actual math by vehicle, compared with gas, along with the two changes that shift the number most.
The numbers behind the estimate
The 2026 U.S. average residential electricity price is currently ~18.3¢/kWh (U.S. Energy Information Administration, Electric Power Monthly), up from ~16.5¢/kWh earlier this year, and it is the rate behind all of this guide's calculations.
Every monthly estimate below assumes ~1,100 miles/month, the typical American's average driving distance (~13,500 miles/year according to Federal Highway Administration data).
Fueling a typical new gas sedan costs ~14.8 cents/mile at the 2026 U.S. average regular-gas price of about $4.14/gallon (AAA), a sharp rise from ~$3.15/gallon earlier this year, and 28 mpg combined (EPA). Charging an EV at home on the same average electricity rate costs roughly 4.4–9.4 cents/mile.
Many utilities' off-peak or EV-specific overnight plans cost 30–50% less than the standard residential rate, which is the biggest lever that most owners haven't yet pulled.
Monthly cost by vehicle
Battery size matters less than efficiency in determining the bill. Even at an identical electricity rate, a heavy truck uses more kWh per mile than a light sedan.
| Vehicle | EPA efficiency | Cost per mile* | Monthly cost* |
|---|---|---|---|
| Tesla Model 3 (RWD) | ~24 kWh/100mi | ~4.4¢ | ~$48 |
| Hyundai IONIQ 5 | ~29 kWh/100mi | ~5.3¢ | ~$59 |
| Chevrolet Equinox EV | ~30 kWh/100mi | ~5.5¢ | ~$61 |
| Ford Mustang Mach-E | ~35 kWh/100mi | ~6.4¢ | ~$71 |
| Rivian R1T | ~51 kWh/100mi | ~9.4¢ | ~$103 |
*Figures use the current 18.3¢/kWh U.S. average residential rate and ~1,100 miles/month. Your local rate and driving mix will push them higher or lower.
Look at the range: drivers of a Model 3 and an R1T who cover the same distance at the same electricity rate pay over twice as much per month for the R1T, entirely because of efficiency. If you are still comparing vehicles, efficiency figures deserve as much weight as sticker price for anyone with heavy monthly mileage.
Home charging vs. gas, side by side
Gas prices fluctuate more than electricity rates, and 2026 shows it clearly, with the national average climbing from about $3.15/gallon earlier this year to roughly $4.14/gallon as of early September. A gas sedan at $4.14/gallon and 28 mpg now costs about 14.8 cents per mile, or about $163/month on the same 1,100-mile baseline used above. Each EV in the table beats that, and the most efficient ones win by a wide margin, with a Model 3 owner paying well under a third of the gas figure. Less efficient EVs narrow the gap and an off-peak electricity rate widens it, yet in any realistic 2026 scenario home charging has the lower cost per mile, and by a bigger margin than when gas was cheaper.
Does charging speed affect the bill: Level 1 vs. Level 2?
Not in any meaningful way. Utilities bill you for energy and not for how quickly it arrives, so a kWh costs the same whether it flows over 3 hours on a Level 2 circuit or 30 hours on a standard 120V outlet. One practical catch is that a slow overnight Level 1 session keeps the car plugged in, and sometimes conditioning itself, for much longer, which can add a little avoidable energy use compared with a Level 2 session that ends within a couple of hours. Daily chargers still on Level 1 can see the upgrade options in our best home EV charger and best Level 2 EV charger roundups, and our installation cost guide covers what wiring a Level 2 circuit costs, which is separate from the running cost discussed here.
Because the bill comes out the same whichever speed you choose, the decision rests on convenience and not on cost. A plug-in portable such as WenStorm’s Level 1 (16A, $169.99) or Level 2 (32A on a NEMA 14-50 outlet, $219.99) lets you start with whatever outlet you have and doesn’t add an installation line to the budget. Both come with a 25-foot cable, a J1772 or NACS connector, and a 2-year warranty. Neither has an app, so scheduling for off-peak rates has to be set in your car or through your utility’s plan.
Emporia Vue Energy Monitor
It clips onto the breaker that feeds your charger and measures actual kWh for each charging session, the only route to your true cost per mile in place of a national estimate.
Combine it with Emporia's Level 2 chargers to see usage and charging data together in a single app.
It can also show whether your panel has spare capacity before you commit to a larger charger.
Free two-day Prime shipping can get a monitor like this onto your panel within days rather than after a long wait, and new members can try Prime free for 30 days.
The two changes that actually move your bill
If your provider offers an off-peak or EV-specific rate, switch to it. Taking 30–50% off the ~$50–$90/month baseline above adds up to real savings, and it normally takes a single signup instead of a hardware purchase.
Use a smart charger's app to schedule sessions in that off-peak window, rather than plugging in as soon as you get home during peak-rate hours. Our best smart EV charger guide shows which chargers make this a real return on investment and which offer a feature you'll never touch.
Solar owners can send surplus daytime production into the car instead of exporting it at a lower buyback rate, which can bring the effective cost per mile close to zero for those miles. Our best solar EV charger guide explains how that pairing works in practice.
Take a measurement instead of guessing. A home energy monitor such as the Emporia Vue above converts "probably around $50 a month" into an exact figure based on your real rate plan and driving habits. The same applies to WenStorm's portable chargers, which have no app of their own to report usage, so a monitor on the circuit feeding them is how you would get a measured number.
The bottom line
Plan on $48–$103 a month to charge a typical EV at home in 2026, a range set mostly by the vehicle you drive and not by the charger, and that figure now beats a comparable gas car's fuel cost by an even wider margin since pump prices have risen toward $4.14/gallon. A new charger is not the quickest way to lower it. An off-peak utility rate plan combined with a charging schedule that takes advantage of it is.

Frequently Asked Questions
What does it cost per month to charge an electric car at home?
At the current 2026 U.S. average residential electricity rate of about 18.3¢/kWh (EIA) and the typical American average of roughly 1,100 miles of driving a month, most EV owners pay $48–$103 a month. Efficient sedans such as the Tesla Model 3 sit near the bottom of that range, while heavier trucks such as the Rivian R1T sit near the top. Any of these figures can drop by 30–50% on an off-peak EV utility rate plan.
Does charging an EV at home cost less than filling up with gas?
Usually yes, and by a lot, with the gap growing in 2026 as gas prices rose. At the current U.S. average gas price of roughly $4.14/gallon (AAA) and 28 mpg for a typical new sedan, gasoline works out to about 14.8 cents per mile. Charging an EV at home on the national average electricity rate costs about 4.4–9.4 cents per mile depending on the vehicle, and less again on an off-peak utility rate, often a third or less of gasoline's per-mile cost.
Is Level 2 charging more expensive in electricity than Level 1?
No. Fully charging the same battery takes the same total kWh either way, because you pay for energy and not for amperage, so the two levels differ in speed but not in cost. Level 2's financial advantage comes down to efficiency: finishing sooner leaves less time for vampire drain from climate preconditioning or cabin heating and cooling, which can add a small, avoidable amount of energy use to a slow overnight Level 1 session.
What are the ways to reduce my home EV charging costs?
Start by moving to your utility's off-peak or EV-specific rate plan if there is one, since many charge 30–50% less overnight than the standard residential rate. Then use a smart Level 2 charger's app to schedule charging within that window, instead of plugging in as soon as you arrive home. Solar owners should direct daytime surplus into the car and not export it at a lower buyback rate. Finally, verify that your charger and car are communicating at full amperage, because a misconfigured circuit can waste charging time quietly without reducing the bill.
How can I find out exactly what it costs me to charge my EV?
Your utility bill reflects the whole household's usage and not just the car, so a dedicated energy monitor is the straightforward answer. A whole-home monitor such as the Emporia Vue clips onto the circuit that feeds your charger and records actual kWh for each session, which is the only way to check that your real cost per mile matches this guide's estimates instead of a national average.
