What can change your real cost
- Your own rate. The Hawaii average is 46.41 cents per kWh; your bill may show more or less. Time-of-use plans can charge less at night.
- Public fast charging. It is priced by the network and usually costs more than home power. These numbers are home charging only.
- Driving and weather. EPA figures are test results. Cold weather, highway speed and heavy loads use more power.
- Gas prices. The gas side uses a national average. If gas near you is far from $4.28, the savings change.
Common questions
How much does it cost to charge an EV at home in Hawaii?
About $17.23 per 100 miles for the median model year 2026 EV (37.13 kWh per 100 miles, EPA) at Hawaii's average home electricity price of 46.41 cents per kWh (EIA, Year-to-Date through August 2026). At 11,106 miles a year that is about $1,914. A Tesla Model 3 Premium RWD costs $11.44 per 100 miles; a Chevrolet Silverado EV Extended Range WT costs $22.20.
Is charging an EV cheaper than gas in Hawaii?
For the median EV, yes. The same 11,106 miles in the median regular-gasoline car (22 mpg combined, EPA) at the national average gas price of $4.28 a gallon costs about $2,161 a year, against $1,914 to charge at home in Hawaii. That is about $247 less. This uses the national gas price because we have no state gas prices; a higher or lower price near you changes the gap.
Where does Hawaii rank for home electricity price?
Hawaii is number 51 of 51 (50 states and DC), where 1 is the lowest price. Its 46.41 cents per kWh is 155% above the US average of 18.19 cents (EIA, Year-to-Date through August 2026).
What does a Level 2 home charger cost to install in Hawaii?
A typical range is $940 to $3,125, an estimate that includes the 240-volt circuit, the outlet or hardwired charger and a permit, from local electrician pay and material prices. Panel size and the distance from the panel to the garage move the price the most.
Does public fast charging cost the same as charging at home?
No. Public fast chargers set their own prices and they are usually higher than home electricity. This page covers home charging only and does not give a public charging price.
Can my rate be different from the state average?
Yes. The number here is the average for all homes in the state. Some utilities have time-of-use plans with a lower price overnight, and some have tiers that cost more as you use more. Your bill shows your own cents per kWh; type it into the formula below.
