How do gas and electricity costs compare in Arizona? The average residential electricity rate in Arizona is 15.6 cents per kilowatt-hour (kWh). That is below the national average residential electricity rate of 18.8 cents per kWh. The national average electricity rate across all sectors (residential, commercial, and industrial) is 14.2 cents per kWh. These electricity rates matter because they directly affect how much it costs to charge an electric vehicle at home. Most EV owners charge at home overnight using standard residential electricity, so the residential rate is the most relevant number for comparing fuel costs between gas and electric vehicles. Here is how the cost per mile breaks down in Arizona: Gasoline vehicle (average 25.4 MPG): $0.203 per mile Electric vehicle (average 0.30 kWh per mile): $0.047 per mile Driving electric in Arizona is approximately 77% cheaper per mile than driving on gasoline. Is it cheaper to drive electric in Arizona? Based on the average driver covering 15,000 miles per year, here is what annual fuel costs look like in Arizona: Gasoline vehicle: approximately $3,048 per year (at $5.16 per gallon and 25.4 MPG average) Electric vehicle: approximately $702 per year (at 15.6 cents per kWh and 0.30 kWh per mile) That is an estimated annual savings of $2,347 by driving electric in Arizona. Over a typical 5-year ownership period, that adds up to roughly $11,734 in fuel savings alone, not counting the additional maintenance savings that come with an electric vehicle (no oil changes, fewer brake replacements, and no transmission service). These estimates assume home charging at residential electricity rates. Public DC fast charging is typically more expensive, ranging from $0.30 to $0.60 per kWh depending on the network and location.
