Annual Cost: Gas vs. Electric (15,000 miles/year)

Fuel / charging$1,750$600$1,150 (EV)

Annual total$4,900$3,550$1,350/yr saved

At $3.50/gallon and $0.14/kWh, an EV saves about $1,350/year in running costs. Over 10 years, that's $13,500 — often enough to offset the higher purchase price, especially with the $7,500 federal tax credit.

When an EV Makes Financial Sense

✅ You can charge at home — Home charging at off-peak rates ($0.08–$0.14/kWh) is 60-70% cheaper than gas. Without home charging, public charging closes the gap significantly.
✅ You qualify for the $7,500 tax credit — This erases most or all of the EV price premium. Check fueleconomy.gov for eligible models.
✅ You drive 12,000+ miles/year — More miles = more fuel savings. High-mileage drivers benefit most from EVs.
✅ You plan to keep it 5+ years — The longer you own an EV, the more the fuel and maintenance savings compound.

Frequently Asked Questions

Are electric cars really cheaper to own than gas cars?▼
Over 5–10 years of ownership, yes — typically $10,000–$25,000 cheaper when you factor in fuel savings ($1,000–$2,000/year), lower maintenance ($500–$800/year), and the federal tax credit ($3,750–$7,500). The upfront cost is higher, but running costs are dramatically lower. The breakeven point is typically 3–5 years.
How much does it cost to charge an EV at home?▼
At the national average of $0.14/kWh, charging a typical EV (3–4 miles per kWh) costs about $0.04/mile or $50/month for 12,000 miles/year. That compares to $120–$180/month in gas for a 30 MPG car. Installing a Level 2 home charger costs $500–$2,000.
Do electric cars cost more to insure?▼
Yes, typically 15–25% more ($200–$500/year extra). This is because EVs cost more to repair due to expensive battery packs and specialized parts. However, some insurers offer EV discounts, and rates are falling as EVs become more common.
What about EV battery replacement cost?▼
Most EV batteries are warrantied for 8 years / 100,000 miles and are expected to last 200,000+ miles. Replacement costs $5,000–$15,000, but the vast majority of owners never need one. Battery degradation is typically only 10–15% after 200,000 miles in modern EVs.
