How the Gas vs EV Comparison Works

This calculator computes the full total cost of ownership (TCO) for a gas car versus an electric vehicle over your chosen ownership period:

  1. Purchase cost: Initial price minus any federal or state tax credits and incentives for the EV.
  2. Fuel vs electricity: Gas cost is calculated from MPG, annual mileage, and your local gas price. EV energy cost uses efficiency (mi/kWh), mileage, and electricity rate.
  3. Maintenance: EVs typically cost 30–50% less per year — no oil changes, fewer brake replacements (regenerative braking), no spark plugs or timing belts.
  4. Depreciation: Each vehicle's resale value (as % of purchase price) is subtracted from total cost, reflecting money recovered at end of ownership.
  5. PRO charts: Annual cost breakdown, 10-year cumulative projection with 3 price scenarios (optimistic/baseline/pessimistic), CO₂ comparison, and a sensitivity table showing break-even under 25 price combinations.

Worked Examples: Gas Car vs EV Over 5 Years

Example 1 — City Commuter (10,000 miles/year)

  • Gas car: $28,000 purchase, 32 MPG, $3.50/gal → ~$39,500 total 5-year cost
  • EV: $38,000 − $7,500 credit = $30,500 net, 4.2 mi/kWh, $0.13/kWh → ~$33,500 total
  • EV saves: ~$6,000 over 5 years | CO₂ reduction: ~3,200 kg/year

City driving maximizes EV efficiency. Regenerative braking recaptures energy on every stop, and low mileage means home overnight charging always covers daily needs.

Example 2 — Long-Distance Driver (25,000 miles/year)

  • Gas car: $35,000, 28 MPG, $3.50/gal → ~$60,000 total 5-year cost
  • EV: $47,000 − $7,500 credit = $39,500 net, 3.8 mi/kWh, $0.13/kWh → ~$48,000 total
  • EV saves: ~$12,000 over 5 years | CO₂ reduction: ~8,000 kg/year

High-mileage drivers get the fastest break-even and largest absolute savings. Mix of home and public DC fast charging; even at $0.35/kWh public rates, total EV energy cost beats gas.

Example 3 — Mixed-Use Suburban Driver (15,000 miles/year)

  • Gas car: $32,000, 30 MPG, $3.50/gal → ~$47,000 total 5-year cost
  • EV: $42,000 − $7,500 credit = $34,500 net, 4.0 mi/kWh, $0.13/kWh → ~$42,000 total
  • EV saves: ~$5,000 over 5 years | Break-even: ~4 years

Typical US driver scenario. With a Level 2 home charger ($600–900 installed), the EV charges overnight at the cheapest rate, delivering consistent savings and near-zero daily charging stress.

FAQ

Is an electric car cheaper to run than a gas car?
Yes, EVs typically cost 50–70% less per mile. Electricity at $0.13/kWh and 4 mi/kWh = $0.033/mile vs. $0.117/mile for gas at $3.50/gal, 30 MPG — about 72% cheaper per mile. Add skipped oil changes ($80–150 each), longer brake life from regenerative braking, and no spark plugs or timing belts. The catch is a higher purchase price. Enter your mileage and incentives above to find your personal break-even year.
What is the total cost of ownership (TCO) for an EV vs a gas car?
TCO covers purchase price minus incentives, annual fuel or electricity, maintenance, insurance, and depreciation. A $45,000 EV with a $7,500 federal credit nets $37,500 — then ~$480/year electricity and ~$500/year maintenance. A $35,000 gas car adds ~$1,500/year fuel and ~$900/year maintenance. Over 5 years at 12,000 mi/year, the EV is typically $4,000–$8,000 cheaper when federal and state incentives apply. Use our car cost calculator for a full ownership breakdown.
How many miles until an EV pays for itself vs a gas car?
Typically 50,000–100,000 miles. If the EV costs $8,000 more after incentives and saves $1,200/year on fuel and maintenance combined, break-even arrives in roughly 6–7 years at 12,000 mi/year. High-mileage drivers (20,000+ mi/year) break even in 4–5 years; low-mileage drivers (<8,000 mi/year) may take 10+ years. Enter your exact prices and annual mileage above for a personalized break-even calculation.
What costs more: charging an EV or filling up a gas car?
Charging is cheaper. Home charging at $0.13/kWh and 4 mi/kWh = $0.033/mile vs. $0.117/mile for gas at $3.50/gal, 30 MPG. For 12,000 mi/year: ~$395 electricity vs. ~$1,400 gas — over $1,000 savings annually. Public DC fast charging runs $0.30–0.45/kWh, raising EV cost to $0.08–0.11/mile — still usually cheaper than gas. Maximum savings come from home charging overnight on off-peak electricity rates.
What EV tax incentives are available in the US in 2025?
The federal Clean Vehicle Credit offers up to $7,500 for new EVs (income limits: $150k single/$300k joint; MSRP cap $55k cars/$80k SUVs/trucks). A $4,000 used EV credit applies to pre-owned EVs under $25k. States add more: California up to $4,500, Colorado $5,000, New York $2,000. Incentives change frequently — verify current eligibility on fueleconomy.gov or the IRS Clean Vehicle Credit page before purchasing.
Is a plug-in hybrid better than a full electric car?
It depends on your situation. Plug-in hybrids (PHEVs) offer 20–50 miles of EV range plus a gas engine as backup — ideal with limited home charging or frequent long trips. Full EVs deliver the lowest per-mile running costs and zero tailpipe emissions but require charging access. If you drive under 40 miles daily and can charge at home overnight, a full EV typically wins on 5-year TCO. PHEVs bridge the gap for uncertain charging situations.
What is range anxiety and is it still a concern in 2025?
Range anxiety — fear of running out of battery — is shrinking fast. Most 2025 EVs offer 250–400+ miles of range, and the US now has 170,000+ public charging outlets, including Tesla Superchargers open to all brands. Apps like PlugShare and ABRP simplify long-trip planning. For daily commutes under 50 miles, home overnight charging eliminates range anxiety entirely. The main remaining concern is fast-charging availability in remote rural areas.
How much does EV maintenance cost vs a gas car?
EVs cost 30–50% less to maintain annually. You skip oil changes ($80–150, 2–3×/year), spark plugs, timing belts, and exhaust system work. Regenerative braking extends brake pad life 2–3×. You still need: tire rotations, cabin air filter, coolant checks, and wiper blades. Typical annual EV maintenance: $400–600 vs. $800–1,200 for a gas car. Over 5 years that is $2,000–3,000 in maintenance savings — a significant part of the EV financial case.
How does cold weather affect EV range?
Cold temperatures reduce EV range 15–40% at 20°F (−7°C) compared to 70°F (21°C). Battery chemistry slows in the cold and cabin heating draws significant power from the pack. Mitigations: precondition the battery and cabin while still plugged in, park in a garage, use seat heaters instead of main HVAC. Most EVs show a real-time winter-adjusted range estimate. In cold-climate regions, add a 25–30% range buffer when selecting an EV model.
How does battery degradation affect EV resale value?
EV batteries typically lose 2–3% capacity per year, retaining 80–85% health at 8–10 years. Most manufacturers warrant the battery for 8 years/100,000 miles to at least 70% capacity. Degradation rarely requires replacement within the first decade. Newer EVs (Tesla, Hyundai Ioniq, Chevy Bolt) display battery state-of-health reports. For resale, buyers increasingly check these reports; strong battery retention correlates with higher used-car prices on the private market.
How much does EV insurance cost compared to a gas car?
EV insurance runs 5–15% higher on average, mainly due to higher repair costs — specialized parts and high-voltage battery systems increase labor rates. Average annual premiums: $1,500–$2,200 for EVs vs. $1,200–$1,800 for comparable gas cars. Some insurers offer EV-specific discounts; Tesla Insurance (in ~15 states) uses telematics pricing. Get at least three quotes — insurance cost can vary by $500+/year between providers for the same EV model.
What is the environmental impact of switching to an EV?
An average US EV produces 60–80% fewer lifecycle CO₂ emissions than a gas car, even accounting for battery manufacturing (~10–12 tonnes CO₂ upfront). The EV breaks even with a gas car on lifetime emissions in about 1–3 years on the average US grid. As the grid adds more renewables, the advantage grows each year. Charging on solar or wind reduces per-mile emissions to near zero. This calculator estimates your annual CO₂ savings in kilograms.
How long does it take to charge an EV at home?
Level 1 (120V outlet): adds 4–5 miles/hour — adequate for under 40 miles/day. Level 2 home charger (240V, $500–$1,000 installed): adds 20–30 miles/hour, fully charging most EVs in 6–10 hours overnight. Level 3 DC fast chargers at public stations: 100–200+ miles in 20–30 minutes, but cost 2–3× more per kWh. For daily use, Level 2 is the practical choice and the installation qualifies for a 30% federal tax credit (up to $1,000).
Does an EV save more money in city or highway driving?
EVs are most efficient in city driving, where regenerative braking recaptures energy lost in deceleration. At highway speeds (70+ mph), EV efficiency drops 20–30% — similar to how gas fuel economy falls on highways. Gas cars are relatively more efficient on highways vs. city stop-and-go. Even so, highway EV charging still costs less per mile than gas. City commuters extract the largest savings, but highway drivers still reduce fuel costs significantly compared to gasoline.
How do I calculate the break-even point between a gas and electric car?
Formula: Break-even (years) = (EV net cost − gas car cost) ÷ annual savings. Example: $37,500 net EV vs. $30,000 gas car = $7,500 premium. Annual savings: $1,000 fuel + $400 maintenance = $1,400/year. Break-even: $7,500 ÷ $1,400 = 5.4 years. After break-even, every year saves $1,400. This calculator does this automatically — enter your vehicle prices, mileage, and energy rates to see your exact break-even year and total savings.
