Beyond the Sticker Price
When comparing EVs to gas cars, most people look at the purchase price and stop there. That's a mistake. The total cost of ownership (TCO) includes fuel, maintenance, insurance, tax incentives, and depreciation — and when you add it all up, the picture changes dramatically.
Let's break down every cost category with real 2025 data.
Fuel Costs: Where EVs Dominate
This is the biggest ongoing savings for EV owners.
The Math
- Average US electricity rate: $0.16/kWh (EIA, 2025)
- Average EV efficiency: 30 kWh/100 miles
- Cost per mile (EV): $0.048
Compare to gas:
- Average US gas price: $3.50/gallon (EIA, 2025)
- Average gas car efficiency: 28 MPG
- Cost per mile (gas): $0.125
EVs cost 62% less per mile to fuel. For a driver covering 12,000 miles per year, that's:
| | EV | Gas Car | Savings | |---|---|---------|---------| | Annual fuel cost | $576 | $1,500 | $924/yr | | 5-year fuel cost | $2,880 | $7,500 | $4,620 |
And that's using national averages. In states with cheap electricity (Washington at $0.10/kWh) or expensive gas (California at $4.80/gal), savings are even larger.

Maintenance: The Silent Savings
EVs have dramatically fewer moving parts than gas cars:
| Component | Gas Car | EV | |-----------|---------|-----| | Engine oil changes | Every 5-7K miles | None | | Transmission fluid | Every 30-60K miles | None (single-speed) | | Spark plugs | Every 30-100K miles | None | | Timing belt | Every 60-100K miles | None | | Exhaust system | Repairs over time | None | | Brake pads | Every 30-50K miles | Every 75-100K miles (regen braking) | | Coolant | Periodic | Periodic (less frequent) |
Annual Maintenance Costs
According to a 2024 Consumer Reports study:
- Gas car average: $900/year
- EV average: $400/year
- Annual savings: $500
Over 5 years: $2,500 in maintenance savings.
The biggest factor: no oil changes and drastically reduced brake wear thanks to regenerative braking. Many EV owners go 100,000+ miles on original brake pads.
Insurance: EVs Cost More (For Now)
This is one area where EVs currently lose:
- Average EV insurance: $2,300/year
- Average gas car insurance: $1,900/year
- Difference: +$400/year for EVs
The higher cost is driven by:
- Higher repair costs (battery and electronics)
- More expensive replacement parts
- Fewer qualified EV repair shops
However, this gap is narrowing as more shops tool up for EVs and insurance companies gain more data.
5-year insurance premium difference: +$2,000 for EVs.
Federal and State Incentives
The 2025 federal EV tax credit structure:
- New EVs: Up to $7,500 federal tax credit (income and price caps apply)
- Used EVs: Up to $4,000 federal tax credit
- State incentives: Vary widely — Colorado offers $5,000, California offers $2,000-7,500 based on income
For a qualifying new EV: $7,500+ in incentives can dramatically change the math.
Depreciation: The Landscape Is Changing
Historically, EVs depreciated faster than gas cars. But the trend is shifting:
2025 depreciation data (3-year, average):
- Tesla Model 3: 35% depreciation
- Toyota Camry: 30% depreciation
- Hyundai Ioniq 5: 40% depreciation
- Honda CR-V: 28% depreciation
Tesla models hold value better than most EVs. Newer EV models from Hyundai, Kia, and others are improving as demand grows.
For a $40,000 vehicle, the difference in depreciation between a typical EV and gas car over 5 years is roughly $2,000-5,000 more for the EV — but this gap shrinks each year.
The 5-Year TCO Comparison
Let's put it all together for a $40,000 EV vs. a $35,000 comparable gas car:
| Category | EV (5 years) | Gas Car (5 years) | |----------|-------------|-------------------| | Purchase price | $40,000 | $35,000 | | Federal tax credit | -$7,500 | $0 | | Net purchase price | $32,500 | $35,000 | | Fuel (60K miles) | $2,880 | $7,500 | | Maintenance | $2,000 | $4,500 | | Insurance | $11,500 | $9,500 | | 5-Year Total | $48,880 | $56,500 | | Savings | $7,620 | — |
Even with higher insurance costs and a higher sticker price, the EV saves over $7,600 in 5 years. Without the tax credit, the EV still saves about $100 — essentially breaking even on a higher purchase price while producing zero tailpipe emissions.
When Gas Still Wins (For Now)
To be fair, there are scenarios where a gas car is still cheaper:
- Very cheap gas + expensive electricity (rare but exists)
- Ultra-low mileage (under 5,000 miles/year — fuel savings don't add up)
- No access to home charging (relying solely on public fast chargers is more expensive)
- No tax credit eligibility (income over caps)
