Electric vs Gas Car Cost Calculator

Choosing between an electric vehicle (EV) and a gasoline car is one of the largest financial decisions a household can make. The sticker price is just the beginning — what really matters is total cost of ownership over several years.

Key cost components:

1. Purchase price: EVs typically cost $5,000–$15,000 more upfront than comparable gas cars. However, government incentives (e.g., $7,500 federal tax credit in the US) can narrow this gap significantly. Always check current incentives in your country/region.

2. Fuel / energy cost:

• Gas cars: Average fuel efficiency is around 30 mpg (12.8 km/L). At $3.50/gallon ($0.92/L), that’s roughly $0.116 per mile ($0.072/km).
• EVs: Average efficiency is around 3.5 miles/kWh (5.6 km/kWh). At $0.13/kWh, that’s about $0.037 per mile ($0.023/km).
• Result: EVs typically cost 60–70% less to fuel per mile.

3. Maintenance: EVs have no oil changes, fewer brake jobs (regenerative braking extends brake life), no transmission fluid, no spark plugs, and fewer moving parts overall. Average EV maintenance cost is $330–$400/year vs $500–$800/year for gas cars.

4. Insurance: EVs often cost 10–20% more to insure due to higher repair costs and specialized parts.

5. Depreciation: Both types depreciate, but EV depreciation is less predictable due to the evolving battery technology. Some EVs hold value well; others depreciate rapidly.

6. Home charging setup: Level 2 home charger installation costs $500–$1,500 (one-time) but saves significantly over public charging.

The bottom line: Most analyses show EVs breaking even with gas cars in total cost after 3–5 years, depending on fuel prices, electricity rates, and driving distance. High-mileage drivers benefit most from EVs.
