What Arizona Residents Should Know
Electricity in Arizona averages $0.138 per kWh — below the national average — while regular gasoline runs $3.35 per gallon, which is near the U.S. mean. At these rates, an average EV costs roughly $0.04 per mile to drive compared to about $0.11 per mile for a 30-mpg gas car. Over 12,000 miles a year, that translates to approximately $840 in annual fuel savings for the EV owner.
Arizona utilities offer time-of-use rates with off-peak pricing as low as $0.080 per kWh. Charging overnight during off-peak hours can cut your per-mile EV cost by up to 67% compared to peak rates. If you pair off-peak charging with a Level 2 home charger, you can keep annual fuel costs well under $288 — a fraction of what most gas vehicles cost to fuel.
Fuel is only part of the story. EVs skip oil changes and spark plugs and wear brakes far more slowly thanks to regenerative braking, typically saving another $0.04–$0.06 per mile in maintenance — roughly $500–$700 a year at 12,000 miles. The EV case is strongest for Arizona drivers who can charge at home and keep the vehicle for several years; if you rely mostly on public fast charging or drive very little, the advantage narrows.
Arizona residents may also be eligible for up to $250 in state EV incentives. With the federal clean vehicle credits having ended September 30, 2025, state programs are now the main purchase incentive, and they can still meaningfully shorten the payback period on a new electric vehicle. Use the calculator above to see exactly how long it takes an EV to break even in your situation.
