Over five years of average driving, an EV owner typically spends less on energy and upkeep than a gas car owner — but the gap depends heavily on electricity rates, charging habits, and how many miles are driven per year. On fuel alone, EV “refueling” costs generally run 40–60% lower than gasoline per mile. On maintenance, EVs tend to save owners a further 30–50% over the same period, mainly because there’s no oil, no exhaust system, and far less brake wear. The exact numbers swing widely by region, electricity price, and vehicle class — so below we break down the real math, not just the headline claim, using global average figures and a side-by-side cost table you can adapt to your own numbers.
Quick Summary
| Cost Category | Gas Vehicle (avg.) | EV (avg.) | Typical Savings with EV |
|---|---|---|---|
| Annual “fuel” cost (12,000 mi/yr) | ~$1,900–$2,400 | ~$500–$900 (home charging) | 55–65% lower |
| Annual maintenance | ~$1,200–$1,400 | ~$400–$600 | 55–65% lower |
| Scheduled service items | Oil changes, filters, belts, exhaust | Tire rotation, cabin filter, brake fluid | Far fewer moving parts |
| Brake wear | Standard friction wear | Reduced via regenerative braking | Longer pad life |
| 5-year total ownership savings (fuel + maintenance) | Baseline | ~$6,000–$10,000 lower, varies by usage | Significant, not universal |
Figures above are global illustrative averages for a mid-size vehicle driven ~12,000 miles/year. Actual savings depend on local electricity and fuel prices, driving style, and vehicle model.
1. Fuel Cost: Gasoline vs. Electricity, Per Mile
The single biggest recurring cost difference between EVs and gas cars is what it costs to go one mile.
Gas vehicles run on fuel efficiency measured in EPA combined mpg. A typical mid-size sedan rated around 32 mpg combined, at a global average gasoline price, costs roughly $0.10–$0.14 per mile to fuel, depending on region and fuel taxes.
EVs run on efficiency measured in miles per kWh (or kWh/100 mi under WLTP testing). A typical EV rated around 3.5–4.0 mi/kWh, charged at home overnight, costs roughly $0.04–$0.06 per mile where residential electricity is moderately priced. Fast-charging at public DC stations narrows this gap considerably — public charging can run 2–4x the cost of home charging, so an EV owner who relies mostly on public fast chargers may see savings shrink to 15–25% rather than 50%+.
Key variable: how you charge.
- Home/overnight charging (Level 1 or 2): cheapest, biggest savings gap vs. gas
- Workplace or destination charging: moderate savings
- DC fast charging only: smallest savings gap, sometimes near cost-parity with gas in high-electricity-price regions
2. Maintenance Cost: Fewer Parts, Fewer Bills
Gas engines have hundreds of moving parts that wear down: pistons, valves, a multi-speed transmission, a fuel injection system, spark plugs, an exhaust system, and a full fluid network (oil, coolant, transmission fluid). Each of these is a scheduled maintenance line item.
EV drivetrains are mechanically simpler. A single-speed reduction gear replaces the multi-speed transmission, there’s no engine oil to change, no spark plugs, no exhaust, and regenerative braking reduces brake pad wear significantly — many EV owners report going 60,000–100,000 miles before a brake job versus 30,000–40,000 miles on a comparable gas car.
What EVs still need:
- Tire rotation and replacement (EVs are often heavier due to battery weight, which can mean somewhat faster tire wear — a partial offset to the maintenance savings)
- Cabin air filter replacement
- Brake fluid flush on a standard interval
- Coolant system service for the battery thermal management system
- Battery health monitoring — most manufacturers back the battery with an 8-year/100,000-mile warranty range, but actual degradation and any out-of-warranty replacement cost varies by model and hasn’t been fully proven out over a 15+ year vehicle life yet
3. What EVs Don’t Save You Money On
To keep this comparison honest, a few costs are roughly equal or can run higher for EVs:
- Insurance: EV insurance premiums are often somewhat higher than a comparable gas car, mainly due to higher vehicle purchase price and more expensive repair parts (especially battery pack and sensor-heavy body panels).
- Tire replacement: Heavier curb weight and instant torque can accelerate tire wear on some EVs.
- Home charging setup: A Level 2 home charger installation is a one-time upfront cost that gas owners don’t have (though it’s often a single expense, not recurring).
- Depreciation: EV depreciation curves have varied more than traditional gas vehicles in recent years, partly due to fast-moving battery and range technology.
4. Putting It Together: 5-Year Cost Comparison
Using average U.S./EU figures for a mid-size sedan driven 12,000 miles/year:
| Cost Category | Gas Vehicle (5 yrs) | EV, Home Charging (5 yrs) |
|---|---|---|
| Fuel / Energy | ~$9,500–$12,000 | ~$2,500–$4,500 |
| Scheduled maintenance | ~$6,000–$7,000 | ~$2,000–$3,000 |
| Brakes/tires (net) | ~$1,200–$1,800 | ~$1,000–$1,800 |
| 5-year total (fuel + maintenance) | ~$16,700–$20,800 | ~$5,500–$9,300 |
| Approx. savings with EV | — | ~$9,000–$13,000 over 5 years |
This table excludes purchase price, insurance, financing, incentives, depreciation, and home charger installation — it isolates only the recurring fuel and maintenance costs the question asks about. Purchase price and any regional incentives should be evaluated separately, as they vary too much by market and vehicle to generalize.
5. How to Estimate Your Own Numbers
Since local electricity rates, gas prices, and driving habits vary so much, the most reliable way to know your personal savings is to run your own numbers rather than rely on national averages. Two inputs matter most: your annual mileage and your ratio of home charging to public fast charging.
Comparison Table: Gas vs. EV at a Glance
| Factor | Gas Vehicle | Electric Vehicle |
|---|---|---|
| Fuel cost per mile | ~$0.10–$0.14 | ~$0.04–$0.06 (home charging) |
| Annual maintenance | ~$1,200–$1,400 | ~$400–$600 |
| Oil changes | Required, every 5,000–7,500 mi | None |
| Brake life (typical) | ~30,000–40,000 mi | ~60,000–100,000 mi |
| Moving drivetrain parts | Hundreds | Dozens |
| Home refueling | Not possible | Possible (Level 1/2 charger) |
| Public refueling speed | 5–10 min | 20–40 min (DC fast charging) |
| Insurance cost | Baseline | Often somewhat higher |
Bottom Line
Over typical ownership, EVs cost meaningfully less to fuel and maintain than gas vehicles — the fuel savings alone are usually the larger factor, and the maintenance savings compound on top of that. But the size of the gap depends entirely on how you charge: home charging delivers the biggest savings, while relying mainly on public fast chargers erodes much of the advantage. For most owners with access to home or overnight charging, the recurring cost case for an EV is strong and well-supported by the numbers above.
