Electric vs Gas Vehicle Calculator
Compare total cost of ownership between EVs and gas vehicles. Calculate fuel savings, break-even points, tax credits, and environmental impact.
Did our AI summary help? Let us know.
EVs typically save $500–1,500/year on fuel; maintenance savings add $500–1,000/year. Federal tax credits up to $7,500 can significantly shorten break-even. Home charging at $0.12/kWh is often 2–3x cheaper than public DC fast charging.

Why: EVs can save money on fuel and maintenance, but higher purchase prices and charging costs affect the math. Tax credits and electricity rates vary by region.
How: TCO = Purchase (minus credits) + Energy costs × Years + Maintenance × Years. Break-even is when cumulative EV cost equals gas cost.

Break-Even Analysis
The electric vehicle becomes cheaper after 0.0 years (0 miles) of ownership.
Tax credits reduce EV purchase price by $7,500.
Environmental Impact
By choosing an electric vehicle, you would save approximately 5,080 pounds of CO2 emissions annually.
Over 5 years of ownership, this amounts to 25,400 pounds of CO2 saved.
Note: Actual CO2 savings vary based on your local electricity generation mix.

💡 Money Facts
EVs have 50–70% lower maintenance costs than gas vehicles.
Gas vehicles lose 20–30% of energy as heat; EVs convert ~85% to motion.
Federal EV tax credit is up to $7,500 for qualifying new vehicles.
EVs produce zero tailpipe emissions; grid mix affects well-to-wheel CO2.
📋 Key Takeaways
- • Total cost of ownership (TCO) includes purchase price, energy/fuel, maintenance, and tax credits—EVs often win long-term despite higher sticker prices.
- • Break-even point shows when cumulative EV costs match gas costs; tax credits and high mileage accelerate break-even.
- • EV efficiency is measured in miles per kWh (typically 3–4.5); gas efficiency in MPG. Lower electricity rates and home charging favor EVs.
- • CO2 savings vary by region—EVs reduce emissions significantly where the grid is cleaner; savings grow over ownership.
💡 Did You Know?
📖 How Electric vs Gas Comparison Works
The calculator compares total cost of ownership (TCO) over your chosen ownership period. It factors in purchase price (minus tax credits for EVs), annual energy/fuel costs, and maintenance. A weighted electricity rate accounts for home vs. public charging mix.
Energy Cost Calculation
EV: Annual kWh = Miles ÷ Miles/kWh. Weighted rate = (Home% × Home rate) + (Public% × Public rate). Gas: Annual gallons = Miles ÷ MPG; cost = gallons × price.
Break-Even
Break-even year = (Gas purchase − EV purchase after credits) ÷ (Annual gas cost − Annual EV cost). When annual gas costs exceed EV costs, the EV pays off over time.
CO2 Savings
Uses ~0.92 lbs CO2/kWh (US grid average) and ~19.6 lbs CO2/gallon gasoline. Actual savings depend on your region's electricity mix.
🎯 Expert Tips
🏠 Maximize Home Charging
Install a Level 2 charger if possible. Home charging is 2–4× cheaper per mile than public charging and extends break-even.
📋 Claim All Tax Credits
Check federal and state incentives. Up to $7,500 federal plus state credits can cut effective EV price by $10K+.
📏 Plan for Your Mileage
Higher annual miles favor EVs—fuel savings compound faster. Under 7,500 miles/year, gas may stay cheaper.
⚡ Check Your Electricity Rate
Rates vary from $0.08 to $0.40+/kWh. At $0.12/kWh, EVs are very cost-effective; above $0.25, savings shrink.

❓ Frequently Asked Questions
Is an EV cheaper than a gas car?
Often yes, over 5–7+ years. EVs have higher purchase prices but lower fuel and maintenance costs. Tax credits and high mileage accelerate break-even.
How much do I save on fuel with an EV?
Typical savings: $800–$1,500/year for 12,000 miles, depending on electricity and gas prices. At $0.12/kWh and $3.50/gal, EVs cost ~$0.03/mile vs ~$0.12/mile for 30 MPG gas.
What is EV range anxiety?
Worry about running out of charge. Most new EVs get 250–350+ miles. Home charging covers daily needs; public chargers handle road trips. Plan routes with charging apps.
How long does EV charging take?
Level 1 (120V): 8–20+ hours. Level 2 (240V): 4–8 hours for full charge. DC fast charging: 20–40 min for 80%. Home Level 2 is ideal for daily use.
Do EV batteries degrade?
Yes, typically 2–3% per year. Most warranties cover 8 years/100K miles at 70% capacity. Newer batteries hold up better.
Are EV maintenance costs really lower?
Yes. No oil changes, fewer brake jobs (regenerative braking), no exhaust system. Expect 40–50% lower maintenance over 5–7 years.
What if I can't charge at home?
Public charging costs more (often 2–4× home rates). Break-even takes longer. Workplace or apartment charging can help.
How do tax credits work for EVs?
Federal credit up to $7,500 for qualifying new EVs (income and MSRP limits apply). State credits vary. Credits reduce your tax liability; they're not a rebate at purchase.
Does cold weather affect EV range?
Yes. Expect 20–40% range loss in very cold weather. Preconditioning while plugged in helps. Plan for winter when comparing range.
