Average Electric Bill in Arizona
Residential · 12-month average, September 2025 – August 2026.
That works out to about $1,951 a year. Among the 50 states and DC, Arizona has the 19th highest average residential bill.
Data current through August 2026 — the latest available from the U.S. EIA, which publishes monthly figures on a roughly two-month delay.
What makes up the bill
Price × usage = bill, exactly: 15.39¢/kWh × 1,057 kWh ≈ $163. A state can land high on either factor — Arizona pays below the national rate but uses much more power than average.

Trend since 2008
Each point is a trailing 12-month average, which strips out the summer/winter swing and leaves the underlying trend. Bills start in January 2008 because that is when EIA began reporting customer counts.

Arizona electricity bills in context
Arizona's average monthly residential electricity bill is $163, ranking it 19th most expensive of the 50 states and DC. This is $5 above the national average of $158, a difference of 2.7%. Arizona achieves this above-average bill despite paying 15.39¢/kWh, which is below the national rate of 18.07¢/kWh. Homes use more electricity here: the state average is 1,057 kWh per month against the national 876 kWh, and this higher usage drives the bill above the national figure.
Over the past year, Arizona's bill rose from $160 to $163, a gain of 1.9%. Over the longer span since August 2021, it has climbed 21.5%, from $134. Since December 2008, when records begin, the bill has grown 44.6%, from $112. The annual bill averages $1,956.
Seasonal swings are sharp. August 2026 peaked at $269, while February 2026 fell to $102, a spread of $167. The twelve-month average of $163 sits between these extremes. Among bordering states, Arizona's bill exceeds those of Nevada ($122), Colorado ($114), Utah ($105), and New Mexico ($101), but sits just below California's $164.

How this is calculated
EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.
bill = revenue ÷ customers · averaged over 12 months (September 2025 – August 2026)
Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Arizona may pay well above or below $163. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
