EV Gas Savings: Why $7 Gas Makes Charging Feel So Good

There is a weird little psychological perk to driving an EV when gasoline prices start climbing: you can pass a packed gas station without stopping. That feeling isn't entirely about politics or EV-vs-gas arguments — it comes down to a much simpler thing: some EV owners are spending dramatically less on everyday energy, especially when they can charge at home overnight.

A recent electric-vehicle discussion captured that feeling perfectly. One driver said their EV could be charged for less than $3, while another reported an overnight electricity rate of just 6 cents per kWh. The numbers vary wildly by location, but the basic idea is the same: when gasoline gets painfully expensive, a home charger suddenly feels like a very good investment.

When the Gas Pump Suddenly Looks Expensive

Nobody buys an EV because they enjoy doing spreadsheet math before breakfast.

But gasoline prices have a funny way of making people do the math anyway.

One Reddit user described the satisfaction of driving an EV while gasoline prices were approaching $7 per gallon, particularly because they could avoid the gas station altogether. The original post was partly tongue-in-cheek, but the underlying financial question is real: how much does your daily commute actually cost in energy?

The answer depends heavily on where you live.

That matters because EV charging isn't automatically cheap everywhere. One driver in the discussion reported paying about 6 cents per kWh overnight, while another said their electricity rate was around 28 cents per kWh in New England. Those are completely different charging economics. So don't fall for the lazy argument that every EV costs pennies to drive.

It depends on your electricity rate, vehicle efficiency, charging location and driving habits.

The Part EV Owners Actually Notice

The biggest advantage isn't necessarily watching the dollar amount fall every time you plug in.

It's the convenience.

A gasoline car needs a dedicated stop. You drive to the station, park beside the pump, swipe your card, fill the tank and leave.

An EV charged at home can turn that entire routine into something you barely notice.

Plug it in when you get home.

Go to sleep.

Wake up with a charged car.

One Ioniq 5 owner in the discussion described charging overnight at a 6-cent-per-kWh rate. Another commenter pointed out that electricity prices can be much higher elsewhere, showing exactly why EV operating costs cannot be judged from one driver's experience alone.

That's the important distinction.

An EV isn't automatically cheap. Home charging can be.

The Driveway Math: Gas Station vs. Home Charger

Here's the calculation that actually matters.

Daily Energy Cost	Gasoline Vehicle	EV With Home Charging
Energy source	Gasoline	Electricity
Where you refill	Gas station	Home, workplace or public charger
Typical payment model	Pay every time you fill up	Electricity added to monthly utility bill
Cost variability	Gas prices can change quickly	Electricity varies by utility and time
Convenience	Dedicated refueling stop	Can charge while parked
Best-case scenario	Efficient car + inexpensive fuel	Efficient EV + cheap overnight electricity

The table doesn't prove that every EV is cheaper.

It shows why the calculation has to be personal.

Take an EV that uses roughly 0.30 kWh per mile. At 6 cents per kWh, the energy cost is about 1.8 cents per mile.

At 28 cents per kWh, the same car costs about 8.4 cents per mile.

That's a massive difference.

And that's before comparing it with the gasoline vehicle sitting in your driveway.

The Five-Minute Fix: Calculate Your Real EV Cost

You don't need an app, spreadsheet or engineering degree.

Step 1: Find Your Electricity Rate

Look at your electric bill and find the price you actually pay per kWh.

Don't use a national average if you can avoid it.

If your utility offers cheaper overnight electricity, use that rate when calculating home charging.

Step 2: Check Your EV's Efficiency

Find the vehicle's kWh-per-mile or miles-per-kWh figure.

For example, if your EV uses 0.30 kWh per mile, that's your starting point.

Step 3: Multiply the Numbers

The simple formula is:

Electricity cost per mile = kWh per mile × electricity price per kWh

At $0.06/kWh:

0.30 × $0.06 = $0.018 per mile

That's 1.8 cents per mile before accounting for charging losses.

At $0.28/kWh:

0.30 × $0.28 = $0.084 per mile

That's 8.4 cents per mile.

Same EV.

Completely different electricity bill.

Step 4: Compare It With Your Gas Car

Now calculate your gasoline vehicle's fuel cost per mile:

Gas cost per mile = gas price ÷ miles per gallon

If gasoline costs $7 per gallon and your vehicle gets 25 mpg:

$7 ÷ 25 = $0.28 per mile

That's 28 cents per mile in gasoline alone.

Suddenly, the reason some EV owners feel smug while passing a gas station becomes pretty obvious.

It's not magic.

It's math.

Three Things the Reddit Debate Gets Right — and Wrong

1. EV savings depend heavily on where you charge

A driver paying 6 cents per kWh has a completely different experience from someone paying 28 cents.

The discussion itself demonstrates that spread.

2. Public charging changes the equation

The cheap-home-charging argument doesn't automatically apply when you're relying heavily on public fast chargers.

That's why comparing an EV's home-charging cost with gasoline is more useful than simply declaring one power source "cheap."

3. The biggest benefit may be convenience

Several commenters focused less on the exact dollar amount and more on avoiding repeated gas-station stops. One described gasoline refueling as a waste of time, while another pointed out that people may spend far more time buying gas during ordinary commuting than they would charging an EV at home.

That's an underrated part of the EV ownership equation.

You aren't just buying electricity.

You're buying back a few minutes here and there.

And over a year, those little stops add up.

---

The funny part is that nobody needs to "win" the gas-vs-EV argument for the math to matter. If your electricity is cheap and you can charge at home, rising gasoline prices can make an EV noticeably easier on the wallet. If electricity is expensive and you're dependent on public charging, the advantage can shrink.

That's why the smartest EV comparison isn't "gas or electric?"

It's "What does a mile actually cost where I live?"
