Average Electric Bill in Arizona
Residential · 12-month average, July 2025 – June 2026.
That works out to about $1,933 a year. Among the 50 states and DC, Arizona has the 18th highest average residential bill.
Data current through June 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: 15.40¢/kWh × 1,046 kWh ≈ $161. A state can land high on either factor — Arizona pays below the national rate but uses much more power than average.

Arizona is $5 a month above (+3.3%) the U.S. average of $156. Neighboring states share fuel mixes, weather, and often a grid operator, which makes them a closer benchmark than the national 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 electricity bill is $160, placing it 19th among the 50 states and DC, counting down from the most expensive. This is $5 higher than the national average of $155, a difference of 3.1%. Arizona's price of 15.41¢/kWh is lower than the national rate of 17.84¢/kWh, but the state's homes use 1,041 kWh per month on average, compared with the national average of 871 kWh. The higher usage pulls the bill above the national level despite the below-average rate.
Over the past year since June 2025, Arizona's average bill has dropped slightly, declining 0.6% from $161. Over the longer run, the increases are steeper: the bill has risen 17.9% since May 2021 and 42.5% since December 2008, when records began. Seasonal swings are pronounced, with August 2025 reaching a peak of $263 and February 2026 dropping to a low of $102, a gap of $161 between peak and lowest month.
Among Arizona's neighbours, only California matches its average bill at $160. Nevada, Colorado, Utah, and New Mexico all cost less to heat and cool over the year, with New Mexico's average of $98 the lowest at the border.

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 (July 2025 – June 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 $161. 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.
