Gas vs Electric: What's the Real Cost?

EVs cost more upfront but significantly less to fuel and maintain. The true comparison isn't sticker price — it's the 5-year total cost of ownership, which accounts for fuel, maintenance, insurance, and depreciation. When you run those numbers, many EV owners come out ahead, especially with the federal tax credit reducing the purchase price gap.

The 5-year window is the standard in the industry because it captures enough fuel and maintenance savings to overcome the EV's higher purchase price for most buyers. After 5 years, EVs tend to be even more favorable since they continue to have lower operating costs while gas cars may face increasing repair bills as they age.

Where EVs Save the Most: Fuel

Fueling an EV at home costs roughly $0.03–$0.05 per mile at average US electricity rates (about $0.16/kWh). A gas car getting 28 MPG at $3.50/gallon costs about $0.125 per mile — roughly 3x more. A driver putting 12,000 miles per year on a gas car spends around $1,500 in fuel annually. The same miles in an EV costs about $400–$600 at home charging rates. That's $900–$1,100 in annual savings, or $4,500–$5,500 over five years just on fuel.

Public DC fast charging erodes this advantage — typically running $0.30–$0.50/kWh, it narrows the gap to about 1.5x cheaper than gas rather than 3x. Drivers who rely heavily on public charging (apartment dwellers without home charging) will see smaller fuel savings.

Where EVs Save the Most: Maintenance

Electric vehicles have far fewer moving parts than gas engines. No oil changes, no spark plugs, no timing belts, no transmission fluid, and no exhaust system. EV owners typically spend $300–$600/year on maintenance (mostly tires and brake fluid), compared to $800–$1,200/year for gas vehicles. Regenerative braking also extends brake pad life significantly — many EV owners go 100,000+ miles before needing brake work.

Over 5 years, the maintenance savings add up to $1,500–$3,000 for the average driver. Combined with fuel savings, total operating cost savings of $6,000–$8,500 over 5 years are realistic for many buyers.

The Purchase Price Gap

EVs still carry a price premium over comparable gas vehicles — typically $5,000–$12,000 more before incentives. The federal EV tax credit (up to $7,500 for new vehicles, $4,000 for used) closes much of that gap for qualifying vehicles. State incentives in California, Colorado, New York, and others can add another $1,500–$5,000 on top.

Not all EVs qualify. The vehicle must be assembled in North America, and there are income caps ($150,000 for single filers, $300,000 for joint) and MSRP limits ($55,000 for cars, $80,000 for trucks and SUVs) for the federal credit. Always verify eligibility on the IRS website before purchasing.

When a Gas Car Still Makes More Sense

For drivers who put on fewer than 8,000 miles per year, the fuel and maintenance savings may not offset the higher EV purchase price within a 5-year window. If you frequently take long road trips without access to a fast-charging network, range anxiety and charging time become real practical concerns. And if you can only charge at public stations — not at home — your electricity costs are higher and the savings are smaller.

Hybrid vehicles often make sense as a middle ground: lower purchase price than a full EV, significantly better fuel economy than a gas car, and no range concerns. Toyota and Honda hybrids in particular have strong reliability records that can make them the lowest total-cost option over 10+ years.

How to Read Your Calculator Results

This calculator compares 5-year total costs including purchase price, fuel, and maintenance. It does not factor in insurance (EVs often cost 10–20% more to insure due to higher repair costs) or depreciation differences. For a complete picture, factor in your local electricity rate, your actual annual mileage, and whether you'll have access to home charging.
