How much does it cost to charge an EV at home in Hawaii?

Data checked October 2026

Short answer

Charging an EV at home in Hawaii costs about $125.31 a month for 1,000 miles in a Tesla Model Y Long Range AWD — 12.5¢ a mile, versus 18.4¢ for a 27.2 mpg car on $5.01 gas.

Hawaii pays 46.41¢/kWh on average for Jan–Aug 2026 — 155% above the U.S. average of 18.19¢, the 1st most expensive of the 50 states and DC.
Regular gasoline averaged $5.01/gal in the West Coast less California region (EIA, week of Oct 19, 2026), so home charging saves about $705 a year at 12,000 miles.
Efficiency matters as much as price: a Tesla Model Y Standard RWD (24 kWh/100 mi) costs $111.38 a month here, a Ford F-150 Lightning ER (48) $222.77.
Ask your utility about a time-of-use or EV rate: overnight energy is often priced well below the average shown here.
270 kWh a month is 53% on top of the 511 kWh an average Hawaii home used each month in 2025.

How to cut it

Set the car or charger to start after your utility's peak window (often 4–9 pm); on an EV or time-of-use plan that is the cheapest single change.
A Level 2 charger idles at about 7 W — roughly 60 kWh a year.
Cold weather and highway speeds raise kWh per mile; the EPA figure is a combined average.

How this was worked out

1,000 mi × 27 kWh/100 mi = 270 kWh; × 46.41¢ (Hawaii average, Jan–Aug 2026, EIA) = $125.31. Gas: 1,000 ÷ 27.2 mpg × $5.01 = $184.08.

EIA's state average includes delivery and fixed customer charges spread over every kWh; your marginal cost for extra kWh may be a little lower. Enter your own rate in the calculator.
