Open tool →Where EVs save money — the actual buckets
EVs typically win on running costs in four places: fuel (electricity is much cheaper per mile than gasoline), maintenance (no oil, no spark plugs, less brake wear), fuel-tax exposure (varies by state) and incentives (state and utility programs you verify yourself). They typically lose on insurance (slightly higher, because the cars cost more), upfront purchase price, and tire wear (heavier, torquier cars eat tires a little faster).
Fuel cost is the biggest single saving
For a typical driver doing 12,000 miles a year, home charging electricity costs roughly $500 a year. The same miles in a 28 MPG gas car at $3.50/gallon costs about $1,500. That $1,000-per-year gap is the biggest single line item in most EV savings comparisons. The EV vs Gas Savings Calculator plugs your own numbers into that math.
Maintenance is the second saving
Electric drivetrains have far fewer moving parts than internal combustion engines. No oil changes, no spark plugs, no timing belts, no transmission service, no exhaust work. Regenerative braking stretches pad life out to 150,000+ miles for many drivers. Real-world EV maintenance averages around $300–400 a year, against $600–800 for a typical gas car — another $300–500 a year that compounds over the life of the car.
Tax credits and incentives
The IRS says the federal new and used clean vehicle credits are not available for vehicles acquired after September 30, 2025 (new, used; read October 15, 2026). Earlier acquisitions can follow different rules, so check the IRS pages before counting any federal credit. State and utility incentives are separate: check your state energy office and electric utility for current programs, and enter only amounts you have verified.
When does the math break even?
Most new EVs cost more upfront than a comparable gas car, but the running-cost savings catch up surprisingly quickly. The EV Break-Even Calculator works out exactly how many years until the savings pay back the premium for your specific situation. The default incentive is $0, so the result reflects only the price premium and your running-cost savings.
