At current U.S. averages, gasoline would have to fall a long way before it beats charging at home. Using the EIA’s average residential electricity price of 18.31 cents per kWh and an EV using about 0.30 kWh per mile from the wall, home charging costs about 5.5 cents per mile — so a 30 mpg gasoline car only breaks even if gasoline drops to about $1.65 a gallon, against the EIA’s October 2026 average of $4.331. Run the same sum in reverse and home electricity would have to reach about 48 cents per kWh before the 30 mpg car wins.
Key Takeaways
- At the EIA averages, gasoline breaks even with home charging at about $1.65 a gallon against a 30 mpg car — far below the $4.331 average.
- Home electricity would have to reach about 48 cents per kWh before a 30 mpg car wins; against a 50 mpg hybrid, about 29 cents.
- Priced DC fast charging is where the gap closes: at an example 45 cents per kWh, cost per mile roughly matches a 30 mpg car.
- Your own rate, your cars’ efficiency and your charging mix set your personal lines.
The Snapshot This Builds On
Our comparison of whether charging an electric car is cheaper than gas runs the per-mile snapshot at today’s prices: about 5.5 cents per mile for home charging against about 14.4 cents for a 30 mpg gasoline car. This article asks the follow-up: how far would prices have to move before that answer flips? All figures below are worked examples from the same EIA averages and the same 0.30 kWh-per-mile assumption.
How Far Gasoline Would Have to Fall
Hold electricity at the 18.31-cent average, and the gasoline price that matches home charging depends on how efficient the gasoline car is:
| Gasoline car | Its cost per mile at $4.331/gal | Break-even gasoline price vs home charging |
|---|---|---|
| 25 mpg | About 17.3 cents | About $1.37 per gallon |
| 30 mpg | About 14.4 cents | About $1.65 per gallon |
| 40 mpg | About 10.8 cents | About $2.20 per gallon |
| 50 mpg hybrid | About 8.7 cents | About $2.75 per gallon |
Even against an efficient 50 mpg hybrid, gasoline would need to fall by more than a third from the October 2026 average before it matched charging at home at the average electricity price.
How Expensive Electricity Would Have to Get
Hold gasoline at $4.331 instead. A 30 mpg car spends about 14.4 cents per mile, so electricity breaks even at about 48 cents per kWh — more than two and a half times the national average. Against a 50 mpg hybrid, the break-even electricity price is about 29 cents per kWh. Households on peak rates can approach the hybrid line, which is why your own rate is the number that matters. Our guide to what home charging costs shows how to work from your bill.
Where the Gap Really Closes: Public Fast Charging
The one place the lines genuinely meet today is the DC fast charger. Public prices vary widely by network and state and are not part of the EIA averages. As a labelled example: at 45 cents per kWh, an EV using 0.30 kWh per mile pays about 13.5 cents per mile — roughly level with the 30 mpg gasoline car. Cheap miles are made at home; heavy fast-charging use gives much of the saving back.
What Moves Your Personal Break-Even
- Your EV’s efficiency. Bigger, heavier EVs use more than 0.30 kWh per mile, which raises every break-even gasoline price above.
- Your gasoline car’s mpg. The comparison is against the car you would actually drive, not a class average.
- Your real electricity price. Off-peak rates sit below the average, pushing the gasoline break-even lower still.
- Your charging mix. The more of your energy comes from priced public chargers, the closer your real cost per mile gets to the gasoline line.
Keeping most charging at home is what holds your side of the line. A wall charger such as the EVDANCE EV-ACT5006T 48A Level 2 wall charger, or a portable unit like the EVDANCE EV-ACS4005T 40A NACS portable charger, makes overnight home charging the default rather than the exception.
Frequently Asked Questions
Does this comparison include maintenance or the price of the car?
No. It covers fuel and charging energy only, the same scope as our per-mile comparison. Purchase price, insurance and maintenance are separate sums.
How do I work out my own break-even?
For the EV: your electricity price in cents, multiplied by your car’s kWh per mile. For the gasoline car: the pump price divided by its mpg. The gasoline price at which the two per-mile figures meet is your break-even.
Can public charging ever beat gasoline?
Level 2 public charging at modest per-kWh prices often can. DC fast charging at higher prices lands near a 30 mpg car’s cost per mile, as the worked example above shows.
