EV vs gas true cost: beyond fuel savings
Complete EV vs gas cost comparison including fuel, insurance, maintenance, depreciation, and incentives.
Put the advice next to real savings examples
The guide gives you the decision framework. The rolling examples show how much the numbers can move once model and location enter the picture.

Why simple fuel comparisons mislead
Most EV vs gas comparisons stop at fuel cost. But ownership cost includes insurance (often higher for EVs), depreciation (varies hugely by model), financing cost, maintenance, and any state/federal incentives. Running all five variables together gives the true picture.
Fuel savings: the foundation
At national averages (16¢/kWh, $3.50/gal), an EV saves $1,000–$1,500/year over a 28-MPG gas car at 15,000 annual miles. In high-gas states (California, Hawaii, Washington) or with a TOU electricity plan, savings reach $1,800–$2,500/year. In low-electricity-rate states like Texas, savings can be even higher.
- ·National average: EV saves ~$1,100/yr vs 28 MPG gas car
- ·California (expensive gas + TOU): $1,800–$2,500/yr savings
- ·Texas (cheap overnight electricity): $1,400–$1,800/yr savings
- ·Mostly fast charging: savings compress to $400–$700/yr
Maintenance savings
EVs avoid oil changes ($80–150/year), transmission service, spark plugs, timing belts, and exhaust system work. AAA's annual maintenance cost study consistently shows EVs saving $700–$1,000/year versus comparable gas vehicles. Brake pads often last twice as long due to regenerative braking.
Insurance: often a headwind
EV insurance typically runs $200–$600/year more than equivalent gas cars. This partially offsets fuel savings. The gap is narrowing as more insurers develop EV pricing expertise. Tesla insurance is particularly expensive ($2,500–$4,000/year for many drivers); mainstream EVs from Hyundai and Kia are closer to parity.
Depreciation: the biggest variable
A Model Y depreciates ~38% over 5 years — similar to a RAV4. A Nissan Leaf may depreciate 55–65%. Choose a model with strong demand and network support, and your total ownership cost improves significantly. Depreciation on popular EVs now looks similar to popular gas vehicles of the same segment.
The bottom line
For most drivers who charge mostly at home and keep the car 5+ years, EVs come out $5,000–$15,000 cheaper in total cost of ownership vs a comparable gas vehicle over 5 years — after accounting for all five cost categories and the federal tax credit. The math gets better as gas prices rise and electricity rates hold steady.
Best Level 2 home chargers
Installing a Level 2 charger is the biggest convenience upgrade in EV ownership — full battery every morning.
Most homes do best with a 40–48 A charger on a dedicated 240 V circuit, but the right pick depends on your panel, connector type, and whether you want smart scheduling for off-peak utility rates.
Wi-Fi, app control, works with any EV. Most flexible amperage (16–50 A).
40 A / 240 V, UL certified, metal enclosure — no-frills workhorse.
Native NACS connector, up to 48 A. Best-in-class for any Tesla.
Plugs into 240 V dryer outlet — no install needed, take it anywhere.
Budget $800–$1,500 installed for many Level 2 setups. A short wiring run from a modern panel can be less, while older homes, long conduit runs, permits, trenching, or panel upgrades can push the project higher.
Before buying hardware, ask your electrician whether your home supports a plug-in NEMA 14-50 unit or should use a hardwired charger. Hardwired installs are often cleaner outdoors and can support higher amperage.
