The Real Cost of Owning an EV vs. Gas Car: A Mileage-Based Breakdown

“EVs are cheaper to own” gets repeated so often it’s treated as settled fact — but the real answer depends on how you drive, how long you keep the car, and what you’re comparing it against. Instead of taking that claim at face value, here’s what the actual cost-per-mile comparison looks like once you factor in fuel, maintenance, and depreciation together.

Key Takeaways

• EVs usually win on fuel/charging cost and maintenance
• Gas cars usually win on sticker price and predictable depreciation
• Depreciation is the wildcard that can shrink or even reverse the EV cost advantage
• The only way to know for certain is to track your own vehicle’s numbers, not a generic estimate

The Comparison at a Glance

Sticker Price Isn’t the Full Story

EVs still tend to carry a higher upfront price than a comparable gas vehicle, even after incentives in many cases. If you stop the comparison there, gas cars look cheaper. But sticker price is only the starting point — the real comparison has to happen over the miles you’ll actually drive, not just the day you buy.

Fuel vs. Charging Costs Per Mile

This is where EVs typically pull ahead:

• Home charging is generally the cheapest way to power an EV, often by a meaningful margin over gasoline
• Public fast-charging narrows that gap considerably
• Local electricity and gas rates both swing the comparison, so your own numbers matter more than a national average

Maintenance Costs Compared

EVs generally cost less to maintain over time:

• No oil changes
• Fewer moving parts in the drivetrain
• Less brake wear thanks to regenerative braking

Gas vehicles carry the ongoing cost of oil changes, exhaust system upkeep, and more complex engine maintenance. This is one of the more consistent, predictable advantages EVs hold, regardless of how many miles you drive per year.

Depreciation: The Wildcard

This is the part that gets left out of most EV-vs-gas comparisons, and it can swing the math significantly. EV depreciation has historically been less predictable than gas vehicles — some models hold value well, while others have dropped sharply as battery technology improves and older models feel outdated faster. A gas vehicle’s depreciation curve tends to be more consistent and easier to predict. If you’re planning to sell or trade in within a few years rather than driving the car until it’s fully worn out, depreciation deserves real weight in your comparison — especially when it’s time to sell.

A Real Cost-Per-Mile Example

Picture two otherwise-comparable vehicles, each driven 12,000 miles in a year:

1. The gas vehicle’s fuel and maintenance costs land noticeably higher per mile than the EV’s charging and maintenance costs
2. That’s a real, meaningful gap in the EV’s favor on those two line items alone
3. But once depreciation is factored in for both, the total cost-per-mile gap can shrink considerably — or even reverse — depending on how each specific vehicle holds its value

The takeaway isn’t “EVs always win” or “gas always wins” — it’s that the full picture only comes into focus once you count fuel, maintenance, and depreciation together, not just one or two of them.

Track Your Own Numbers

Generic comparisons can only tell you so much — the real answer depends on your specific vehicle, your driving habits, and your local energy and gas prices. TORQ Track tracks fuel or EV charging, maintenance, and cost per mile automatically, whichever you drive, so instead of relying on a general estimate, you can see exactly what your own vehicle is costing you, mile by mile. If you drive for a rideshare or delivery platform, TORQ Track Driver nets that cost against your actual earnings too.

Frequently Asked Questions

Is an EV always cheaper per mile than a gas car?

Not always. EVs usually win on fuel and maintenance, but depreciation can close or even reverse that gap depending on the specific model and how long you keep it.

What's the single biggest cost difference between EVs and gas cars?

Maintenance tends to be the most consistent advantage for EVs, since there's no oil changes and less brake wear. Depreciation is the least predictable factor for either vehicle type.

Does home charging really make that much of a difference?

Yes — home charging is generally the cheapest way to power an EV per mile, while relying mainly on public fast-charging narrows the cost advantage over gas considerably.

How do I know my own EV's real cost per mile instead of a general estimate?

The only reliable way is to track your own charging, maintenance, and depreciation over time rather than relying on averages — see our full cost-per-mile breakdown for how to calculate it.

Can TORQ Track handle EVs and gas cars the same way?

Yes — TORQ Track tracks charging or fuel costs, maintenance, and cost per mile automatically regardless of what you drive, so you can compare vehicles on equal footing.
