Average Utility Costs in Hawaii
Typical monthly utility costs in Hawaii are about $547.47/mo, based on 1,000 kWh of electricity and 5,000 gallons of water (plus sewer and trash where available). Compare Hawaii cities below to find cheaper vs more expensive areas.
Electric: HECO (Oahu) and HELCO (Hawaii Island) use Schedule R tiered rates + monthly ECRC. Water: Honolulu BWS (Oahu), Hawaii County DWS (Hilo). Sewer: Honolulu ENV (Oahu); Hawaii County (Hilo—contact for rates). Trash: Honolulu curbside (no separate fee); Hawaii County varies.
Why are Hawaii utility costs so similar across cities? Unlike mainland states with multiple electric providers and municipal utilities per city, Hawaii uses island-wide or county-wide monopolies. All six Oahu cities (Urban Honolulu, East Honolulu, Pearl City, Waipahu, Kailua, Kaneohe) are served by the same three providers—Hawaiian Electric (HECO), Honolulu Board of Water Supply, and Honolulu ENV—so rates are identical. Hilo uses Hawaii Electric Light (HELCO) and Hawaii County DWS, which follow similar tariff structures. No retail electric choice or competing water utilities exist, so you’ll see comparable estimates across the cities we cover.

Assumptions: 1,000 kWh/month and 5,000 gallons/month (where applicable). "Average" values represent the median city estimate; water/sewer/trash medians exclude $0 entries when service or published rates vary by address. Actual bills vary by usage, fees, and provider.
