Average Electric Bill in Hawaii
Residential · 12-month average, September 2025 – August 2026.
That works out to about $2,732 a year. Among the 50 states and DC, Hawaii has the 1st 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: 44.27¢/kWh × 514 kWh ≈ $228. A state can land high on either factor — Hawaii pays well above the national rate but uses less 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.

Hawaii electricity bills in context
Hawaii's average residential electricity bill is $228 per month, the highest of the 50 states and DC. This figure stems from two forces working in opposite directions. Households here pay 44.27¢/kWh, far above the national average of 18.07¢/kWh—a difference of 26.20¢/kWh that pushes the bill sharply upward. However, homes use only 514 kWh per month, compared with the national average of 876 kWh, which pulls it downward. The price effect dominates: the bill runs $70 above the national average of $158, or 43.7% higher.
Over the past year from September 2025 to August 2026, the average bill climbed 9.8% from $207. Over five years since August 2021, it has grown 33.3% from $171. Since December 2008, it has risen 11.6% from $204. Within the twelve-month window, bills peaked at $269 in August 2026 and fell to their lowest in February 2026 at $182, a swing of $87 around the annual average.

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 Hawaii may pay well above or below $228. 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.
