EV vs Gas Savings Calculator

Strip the EV vs gas debate down to the per-mile fuel cost and the gap is hard to argue with. A typical gas sedan at 25 MPG burning $3.40/gallon costs $0.136 per mile in fuel. A typical EV at 0.13 kWh/mile (3.5 mi/kWh efficiency typical for mid-size EVs) at $0.13/kWh average U.S. residential electricity costs $0.017 per mile. That is a roughly 8x difference per mile.

For a typical 12,000-mile year, gas fuel costs $1,632 and EV electricity costs $204 — a $1,428 annual fuel-only gap. Charge on a TOU off-peak rate of $0.08/kWh and EV cost drops further to $0.010/mile or $124/year. Owners in California or the Northeast with $0.25+/kWh rates see a smaller but still substantial gap: roughly $0.033/mile, or $396/year vs $1,632 for gas — still 4x cheaper.

The exception worth noting: a Hummer EV or Rivian R1S towing at 2.0 mi/kWh on a $0.30/kWh rate hits $0.15/mile, basically a tie with gas at $0.13/mile. Heavy EVs in expensive markets are the only realistic case where electricity does not crush gas on per-mile cost. Use the calculator above with your specific car and rate to see your actual gap.

The U.S. Department of Energy and AAA both publish annual maintenance cost data. EVs consistently come in 35 to 45% lower across the typical ownership window, with the gap widening past year five.

What Goes Away

• Oil changes: $60 to $120 per service, 2 to 4 services per year for ICE = $120 to $480/year. EV cost: $0.
• Spark plugs and ignition coils: $150 to $400 every 60,000 miles for ICE. EV cost: $0.
• Timing belt/chain: $400 to $1,200 every 80,000 to 100,000 miles on most ICE. EV cost: $0.
• Transmission service: $150 to $400 every 60,000 miles on ICE. EV cost: $0 (single-speed gearbox in most EVs).
• Exhaust system, catalytic converter, O2 sensors: $500 to $2,500 in lifetime repairs typical. EV cost: $0.

Brake Wear: 2x Longer Life on EVs via Regen

Regenerative braking (the motor acts as a generator under deceleration, slowing the car and recapturing energy) means EV brake pads last roughly twice as long as ICE brake pads. ICE owners typically replace front pads at 40,000 to 60,000 miles. EV owners often see 80,000 to 120,000 miles before pad replacement, sometimes more on cars with strong one-pedal driving modes (Tesla, Bolt, Leaf e-Pedal). Lifetime brake savings: $400 to $800 over 100,000 miles.

What EVs Still Need

Cabin air filter ($30 to $80/year), wiper blades, washer fluid, brake fluid (every 2 to 3 years on most EVs), and tire rotation. Battery coolant flush is occasionally required (every 60,000 to 100,000 miles, $150 to $300). Total EV maintenance averages $0.06/mile vs $0.10/mile for ICE per DOE data.

One real cost where EVs lose to gas cars is insurance. Insurance industry data from 2024-2026 shows EVs cost roughly 5 to 15% more to insure than equivalent ICE vehicles, with luxury EVs (Lucid Air, Mercedes EQS, BMW iX) running 20%+ higher.

Why EVs Cost More to Insure

• Higher repair costs: EV body shops are still rare, parts can take weeks, and battery damage in a moderate collision can total a $40,000 car if the pack is breached.
• Specialized labor: EV-certified technicians charge premium hourly rates, often $150 to $200/hour vs $80 to $130 for ICE shops.
• Higher MSRP: Even with $7,500 federal tax credit, most EVs cost more upfront, which raises comprehensive and collision premiums.
• Faster acceleration: Insurance actuarial models flag EVs as performance vehicles given typical 0-60 times of 4 to 6 seconds on mainstream models.

Real Numbers

A Toyota Camry insurance bill might run $1,400/year for full coverage. The equivalent Tesla Model 3 typically runs $1,600 to $1,750/year — about $200 to $350 more. The insurance gap eats into the fuel savings, but does not erase it. Net annual savings (fuel minus insurance increase) still land at $1,000 to $1,300 for typical mid-size EVs.

EVs eat tires roughly 20 to 30% faster than equivalent ICE vehicles, for two reasons: instant torque and curb weight. A Tesla Model 3 weighs about 4,050 lb vs 3,300 lb for a Toyota Camry. A Rivian R1T weighs 7,100 lb vs 4,700 lb for a Ford F-150. The extra mass plus instant 100% torque from a stop means more force on each tire contact patch.

Real Tire Mileage

An ICE sedan typically gets 50,000 to 60,000 miles on a set of all-season tires. EVs of similar size typically get 35,000 to 45,000 miles. EV tires often cost more upfront because of low rolling resistance compounds and noise-cancelling foam liners (an EV-specific NVH feature). A Model 3 Continental ProContact RX tire costs roughly $250 vs $180 for a Camry equivalent.

Annual Tire Cost Comparison

• Camry: 12,000 mi/year, 55,000 mi tire life, $720 set = ~$157/year amortized.
• Tesla Model 3: 12,000 mi/year, 40,000 mi tire life, $1,000 set = ~$300/year amortized.
• Annual gap: $143 more per year in tire cost for the EV.

Like insurance, tire wear is a real cost that erodes — but does not erase — EV fuel savings. The corrective tip: EV-specific tires (Tesla Model 3 owners often run Michelin Pilot Sport All Season 4 EV) can extend tire life by 15 to 25% versus generic all-season rubber.

Where you live changes the EV vs gas math more than which car you pick. The table below ranks 10 representative states by combined EV economics: electricity rate (lower is better), gas price (higher gas = better EV math), and 2026 incentives.

The used EV market has matured considerably. A 2021 Tesla Model 3 Long Range that originally sold for $52,000 now trades for $24,000 to $28,000. The math on used EVs is appealing — but only if the battery is healthy.

Federal Battery Warranty: Your Floor

All EVs sold in the U.S. since 2012 carry an 8-year / 100,000-mile federal battery warranty (longer in California). The warranty covers excessive capacity loss (typically defined as falling below 70% of original capacity). When buying used, prioritize cars still inside the federal warranty window. A 4-year-old EV with 50,000 miles still has 4 years and 50,000 miles of battery coverage left, which de-risks the largest single component cost.

Battery Health Inspection

Before buying any used EV, get a battery state-of-health (SoH) reading. Tesla shows it directly on the touchscreen with a 100% range estimate. For non-Tesla EVs, services like Recurrent (free for buyers) or local independent EV shops can pull SoH data via OBD-II. Healthy 4 to 5 year old EVs typically show 88 to 95% of original capacity. Anything below 85% on a 5-year-old car is a warning sign.

Used EV Tax Credit

The federal Used Clean Vehicle Credit covers 30% of the sale price up to $4,000 for qualifying used EVs (under $25,000 sale price, 2-year-old or older car, qualifying buyer income). This credit alone can bring a $20,000 used Bolt EV down to $16,000 net cost after tax filing — making it one of the cheapest cars per mile to operate in America.

Trucks are the hardest test case for EV economics because they consume the most energy. A direct 5-year ownership comparison between the F-150 Lightning Extended Range (131 kWh battery, 320 mi range) and the F-150 XLT 3.5L EcoBoost (22 MPG combined) shows the EV still wins, but by a thinner margin than smaller EVs.

Assumptions: 75,000 mi over 5 years, 2.4 mi/kWh Lightning ER mixed driving, $0.13/kWh, 22 MPG F-150, $3.40/gal, AAA maintenance averages.

The Lightning is essentially break-even with the EcoBoost on 5-year total cost despite higher MSRP, because of fuel and maintenance savings plus the federal credit. Owners who tow heavily push the math worse for the Lightning (efficiency drops to 1.5 to 2.0 mi/kWh under tow load). Owners who drive higher miles (20,000+/year) push the math better. For full home-charging cost details on a Lightning-class truck, see the home EV charging cost guide. Adding a Level 2 home charger before June 30, 2026 qualifies for the federal Section 30C credit (30% of cost up to $1,000) — see the federal credit and rebate guide and the EV charger rebate hub for stackable state programs.

The debate between electric vehicles and gas-powered cars often comes down to one question: which one costs less to operate? The answer, for the vast majority of American drivers, is the EV, and it is not even close.

Fuel Costs: Electricity vs Gasoline

The average American drives approximately 12,000 miles per year. At the national average gas price of $3.50 per gallon and a typical sedan fuel economy of 27 MPG, that translates to roughly $1,556 per year in gasoline costs. The same 12,000 miles driven in an average EV achieving 3.5 mi/kWh at $0.16/kWh costs approximately $549 per year in electricity. That is an annual savings of over $1,000 just on fuel.

The savings grow even more dramatic for drivers who commute longer distances or own less fuel-efficient vehicles. A Ford F-150 owner averaging 22 MPG and paying $3.50/gallon spends about $1,909 per year on gas. Switching to an electric truck or SUV could cut that cost by 60% to 70%.

Maintenance Cost Advantage

Beyond fuel savings, EVs have significantly lower maintenance costs. Electric motors have far fewer moving parts than internal combustion engines. There are no oil changes, no transmission fluid, no timing belts, no spark plugs, and no exhaust system components to replace. According to the U.S. Department of Energy, EV maintenance costs average roughly $0.06 per mile compared to $0.10 per mile for gas vehicles. Over 12,000 miles per year, that is an additional $480 in annual savings.

Estimates based on 12,000 miles/year, $3.50/gal, 27 MPG gas car, 3.5 mi/kWh EV at $0.16/kWh. Maintenance figures from DOE and AAA data.

Price per Mile: The Bottom Line

When you combine fuel and maintenance, the average gas car costs roughly $0.16 to $0.19 per mile to operate, while a comparable EV costs $0.05 to $0.07 per mile. That three-to-one cost advantage compounds year after year. Over a typical 5-year ownership period, an EV driver can save $6,600 to $8,000 in operating costs compared to a gas vehicle. Charge at home with an affordable Level 2 charger and your savings grow further by avoiding expensive public charging fees.

Your EV charging costs depend heavily on where you live. Electricity rates across the United States range from as low as $0.10/kWh in states like Louisiana and Oklahoma to over $0.30/kWh in Hawaii and parts of New England. This variation means your annual EV fuel cost could differ by hundreds of dollars depending on your state.

Here is a quick comparison for 12,000 miles driven at 3.5 mi/kWh:

*Gas cost based on 27 MPG at $3.50/gal. Actual gas prices vary significantly by state.

Even in the most expensive electricity states, driving an EV still costs less than gasoline. To calculate your exact savings based on your local rates, use the calculator above or visit our EV Charging Cost Calculator for a detailed per-session cost breakdown.

The upfront cost of an EV is often higher than a comparable gas car, but the total cost of ownership (TCO) tells a very different story. When you factor in fuel savings, reduced maintenance, and available tax credits, many EVs reach a break-even point surprisingly quickly.

Breaking Down the TCO

Let us look at a real-world example comparing a Toyota Camry (gas) to a comparable Chevrolet Equinox EV over 5 years and 60,000 miles:

Estimates based on $3.50/gal, 27 MPG, $0.16/kWh, 3.45 mi/kWh. Tax credit assumes eligibility. Charger cost reflects an affordable Level 2 unit under $300 or a portable EV charger.

Home Charger: A One-Time Investment

A home EV charger is a one-time purchase that pays for itself within months. A quality Level 2 charger costs between $200 and $500, and it saves you $500 to $1,200 per year compared to relying on public DC fast charging. At the average driver's fuel savings of $84 per month compared to gas, even a $500 charger pays for itself in under 6 months. Use the calculator above to find your exact break-even point by entering your charger cost.

Maintenance Savings Add Up

The maintenance advantage of EVs is substantial over a vehicle's lifetime. No oil changes (saving $120 to $200 per year), dramatically reduced brake wear thanks to regenerative braking (saving $100 to $200 per year), and no transmission servicing. Over 10 years, these savings can exceed $5,000 to $8,000. The only significant EV-specific maintenance item is eventual battery replacement, but modern EV batteries are warranted for 8 years or 100,000 miles and typically last well beyond that.
